Avaliação da recuperação das lesões cutâneas por meio da terapia larval utilizando como modelos ratos Wistar /

Nitsche, Maria José Trevizani. January 2010 (has links)
Resumo: A terapia larval consiste na aplicação de larvas vivas estéreis de dípteros obtidas em laboratório sobre lesões, feridas crônicas ou infectadas tendo como finalidade a cicatrização a partir da remoção de secreção e tecido necrosado pelo inseto facilitando, assim, o processo de cicatrização. Apesar da fácil aplicabilidade e do baixo custo, para garantir maior segurança e sucesso em relação a este procedimento dois fatores têm de ser alcançados: a esterilidade das larvas a serem aplicadas e a garantia de que a espécie selecionada para este fim fará uso, durante o seu processo de alimentação na ferida, somente de tecido necrosado. No presente estudo foi avaliada a esterilização e a viabilidade pós-esterilização de larvas de Chrysomya megacephala e Chrysomya putoria (Diptera: Calliphoridae) em hipoclorito de sódio a 0,5% e 1,0%. Adicionalmente, foi avaliado o desempenho (qualidade e tempo de tratamento) dos imaturos dessas mesmas espécies no desbridamento de feridas cutâneas induzidas, usando como modelo animal ratos Wistar. A escolha das espécies foi motivada pela facilidade de obtenção em todo território brasileiro, levando em conta ainda seu comportamento e biologia já descritos em literatura. Os melhores resultados em relação à sobrevida e viabilidade das larvas foram obtidos com o uso do hipoclorito de sódio a 0,5% como agente esterilizante. Após o processo de esterilização, 5-10 larvas/cm2 com 24 horas de vida pós-eclosão, foram aplicadas sobre as lesões induzidas, as quais por sua vez foram cobertas com gaze estéril e esparadrapo. Após 16 horas o curativo foi removido, constatando que as larvas ainda se encontravam vivas e permaneciam apenas no local da lesão, sem invadir tecidos saudáveis, havendo desaparecido o tecido necrótico e as secreções. No grupo controle, sem aplicação de larvas, o tecido necrosado e a secreção ...

Despite the easy applicability and low cost, to ensure greater safety and success in relation to this procedure two factors must be achieved: the sterility of the larvae to be applied and ensure that the species selected for this purpose will use during their feeding process in the wound, only necrotic tissue. In this study we evaluated the sterilization and viability poststerilization of the larvae of Chrysomya megacephala and Chrysomya putoria (Diptera: Calliphoridae) in sodium hypochlorite 0.5% and 1.0%. Additionally, we evaluated the performance (quality and length of treatment) of immatures of these same species in the debridement of wounds induced, using rats as animal model. The choice of species was motivated by the ease of collecting around Brazil, taking into account their behavior and biology has already been described in literature. The best results regarding the viability and survival of larvae were obtained from the use of sodium hypochlorite at 0.5% as a sterilizing agent. After the sterilization process, 5-10 larvae/cm2 with 24 hours of post-hatching, were applied over the induced lesions, which it were covered with gauze and adhesive tape. After 16 hours the bandage was removed, noting that the larvae were still alive and remained only at the injury site, without invading healthy tissue, having gone necrotic tissue and secretions. In the control group without the application of maggots, the necrotic tissue and secretion increased in quantity, considering the same interval of treatment biotherapic. Skin fragments with a size of 1 cm2 from the margin to the center of the lesion were removed from ...

Detecção e estudo sobre o efeito da metanfetamina e do ecstasy no desenvolvimento de imaturos de três espécies de Chrysomya (Diptera: Calliphoridae) de importância forense /

Lima, Carolina Gonçalves Palanch de. January 2009 (has links)
Orientador: Patrícia Jacqueline Thyssen / Banca: Wesley Augusto Conde Godoy / Banca: Carolina Reigada / Resumo: A Entomologia Forense utiliza dados de desenvolvimento e aspectos ecológicos de insetos que se alimentam de corpos em decomposição com o objetivo de auxiliar a resolução de casos na área forense. Uma das principais aplicações, entre outras, é a estimativa do intervalo pós-morte (IPM) que pode ser baseada no ciclo biológico de uma dada espécie. Porém, a falta de informação ou conhecimento sobre as variáveis que interferem de forma direta ou indireta sobre a taxa de desenvolvimento de diferentes espécies pode gerar dados imprecisos em relação à idade do inseto e, consequentemente, ao IPM. Recentemente, devido ao aumento no número de óbitos relacionados ao abuso de drogas, análises toxicológicas têm sido direcionadas a insetos necrófagos, visando complementar informações acerca da causa da morte, assim como garantir maior acurácia ao cálculo do IPM, uma vez que certas substâncias ingeridas antes do óbito podem alterar a taxa de desenvolvimento de algumas espécies que se alimentam dos tecidos de cadáveres. Esse ramo mais recente da entomologia forense é conhecido como Entomotoxicologia. No presente estudo objetivou-se observar o efeito de diferentes concentrações de metanfetamina e ecstasy, derivados anfetamínicos que tiveram seu consumo aumentado nas últimas décadas no Brasil, na taxa de desenvolvimento de imaturos dos califorídeos Chrysomya albiceps (Wiedemann), Chrysomya megacephala (Fabricius) e Chrysomya putoria (Wiedemann), quando acrescidos em dieta artificial apropriada. A anfetamina, metabólito da metanfetamina, não afetou de forma significativa o desenvolvimento larval de C. megacephala, no entanto, aumentou o tempo de desenvolvimento de imaturos de C. putoria, em especial a fase de pupa. O MDMA, principal componente do ecstasy, não alterou a taxa de desenvolvimento larval de C. albiceps e C. putoria, mas acelerou consideravelmente...

One of its main aplication, among others, is to estimate the pos-mortem interval (PMI) that can be based on the life cycle of a specific species. However, the lack of information or knowledge about the variables that can change directly or indirectly the development rate of different species can lead to inaccurate data about the age of the insect and, consequently, the PMI. Recently, due to the increasing number of death related to drug abuse, toxicological analyses have been directed to necrophagous insects intending to provide complementary information about the cause of death, as well as to asure a more acurate estimate of PMI, once some substances ingested before death can modify the development rate of some species that feed on cadaver tissues. This new branch of Forensic Entomology is known as Entomotoxicology. The aim of the present study was to observe the effect of different concentrations of methamphetamine and ecstasy, two amphetamine-like drugs which abuse rose among Brazilians in the last decades, on the development rate of immature of Calliphoridae Chrysomya albiceps (Wiedemann), Chrysomya megacephala (Fabricius) and Chrysomya putoria (Wiedemann), when added to artificial diet proper for them to complete their development. Amphetamine, methamphetamine's metabolite, did not affect significantly the larval development of C. megacephala, although it increased the time of development of C. putoria maggots, specially the pupa stage. MDMA, the main compound of ecstasy, did not alter the larval development rate of C. albiceps nor C. putoria but it accelerated, considerably, the development rate of C. megacephala. Through immunohistochemical analyses it was tried to detect amphetamine in larvae of C. megacephala and C. putoria, but the results were... (Complete abstract click electronic access below) / Mestre

Utilization of Blow Flies (Phormia regina) as Vertebrate Resource Diversity Indicators

Ashton Brooke Jones (13150290) 08 September 2022 (has links)
<p>  </p> <p>Blow flies are often utilized in the field of forensic science due to their ability to aid in the estimation of time since death. Currently, estimations of postmortem interval require assumptions to be made and are prone to a margin of error, prompting research that may contribute to more accurate postmortem interval estimations and help to fill in the gaps of unknown information. Blow flies are necrophagous, feeding on feces and carrion, and therefore, are constantly sampling the environment. This behavior can be exploited in order to monitor the biodiversity in an environment. Through analysis of DNA isolated from the guts of blow flies, information can be obtained regarding what animals have died in an environment, what animals are still living in that environment, and the abundance and diversity of the animals present in a specific environment. Using fly-derived ingested DNA is a viable method for vertebrate resource identification and biodiversity monitoring. Over the course of a two-summer sampling period, in and around two national parks, a total of 162 blow fly (<em>Phormia regina</em>) samples returned a positive vertebrate DNA identification, with 33 species identified from five animal orders. Of the total number of flies collected and analyzed, 23.58% returned a positive vertebrate species identification. The method detected both abundant and common species based on National Park surveys, as well as some uncommon or unknown to the park species. In the SE region, 9 individuals belonging to the Rodentia order, 12 individuals belonging to the Artiodactyla order, 21 individuals belonging to the Carnivora order, 1 individual belonging to the Cingulata order, and 3 individuals belonging to the Lagomorph order were detected. In the SE region, 63% of the individuals detected belonged to the common category, 14% of the individuals detected belonged to the uncommon category, and 23% of the individuals detected belonged to the not in park/unknown category. In the NW region, 42 individuals belonging to the Rodentia order, 46 individuals belonging to the Artiodactyla order, and 28 individuals belonging to the Carnivora order were detected. In the NW region, 52% of the individuals detected belonged to the abundant category, 36% of the individuals detected belonged to the common category, and 12% of the individuals detected belonged to the uncommon category. The relative biodiversity of the sampled environment can be inferred. In the SE region, the Shannon Biodiversity Index was calculated to be 2.28 with an evenness of 0.844, while in the NW region, the Shannon Biodiversity Index was calculated to be 2.79 with an evenness of 0.855. Unsurprisingly, there was greater biodiversity in the Northwest Park samples than in the Southeast Park samples. Additionally, the ideal weather conditions for blow fly collection were determined be at a temperature of between 60- and 80-degrees Fahrenheit, a relative humidity between 50% and 60%, no precipitation, and a wind speed between 2 and 8 miles per hour. This information has further implications in the field of forensic science, specifically dealing with wildlife forensics, pathogen distributions, and can help to improve accuracy in regards to postmortem interval (PMI) estimations. </p> <p>  </p>

Synthesiomyia nudiseta (Diptera: Muscidae) y su importancia en Entomología Forense e investigación aplicada

Ivorra, Tania 07 July 2015 (has links)
Synthesiomyia nudiseta (van der Wulp, 1883) es un múscido de origen tropical y subtropical, siendo la única especie conocida dentro del género Synthesiomyia Brauer & Bergenstamm, 1893. Se trata de una especie con gran importancia forense para la estimación del intervalo postmortem, en diferentes zonas del mundo (p. ej.: Costa Rica, Estados Unidos, India, Malasia, Tailandia). Su presencia en España y Europa es relativamente reciente y en los últimos años se ha citado con cierta frecuencia en autopsias realizadas en el Sureste de la Península Ibérica. Por todo ello, el estudio profundo del ciclo biológico y la biología de S. nudiseta reviste gran importancia e interés tanto en el campo de la investigación básica como aplicada. El principal propósito de esta Tesis Doctoral es establecer las bases que permitan su adecuada aplicación en el ámbito de la entomología forense en nuestro país. A continuación se indican los principales aspectos desarrollados en los diferentes capítulos de la memoria. En primer lugar, se estudia el efecto de la temperatura en el desarrollo preimaginal de S. nudiseta, analizando el crecimiento larvario (longitud) y el desarrollo de la pupa (peso, longitud y diámetro); también se registró el tiempo de desarrollo de cada una de las fases preimaginales y los diferentes estadios larvarios. Con toda esta información, se calculó la temperatura mínima de desarrollo (t0) y los grados-día acumulados (GDA) necesarios para su aplicación en el cálculo del intervalo postmortem. Finalmente se elaboró el diagrama isomorfo para la especie. En segundo lugar, se evaluó el efecto de la competencia larvaria de S. nudiseta con especies de Calliphoridae con importancia forense presentes en esta zona de Europa (Chrysomya albiceps, Lucilia sericata, Calliphora vicina). Los parámetros analizados fueron el tiempo de desarrollo de cada etapa preimaginal, la mortalidad y el tamaño de los adultos de cada una de las especies. En este último caso se utilizaron técnicas de geometría morfométrica mediante el cálculo del centroide y su relación con el tamaño de las alas. Se detectaron diferencias significativas en todos los aspectos analizados demostrando la importancia de la interacción de S. nudiseta con otras especies. El siguiente aspecto estudiado fue la caracterización morfológica y química de las glándulas salivares de S. nudiseta. Las larvas maduras de esta especie segregan una sustancia producida en sus glándulas salivares que permite mimetizar el pupario con el microhábitat donde se encuentre Se realizaron fotos al microscopio electrónico de barrido y con microscopía óptica convencional de esta sustancia. El análisis de las glándulas salivares y de la sustancia que producen permitió entender mejor este mecanismo de defensa pasiva durante el desarrollo preimaginal y se indicó su importancia a la hora de analizar evidencias forenses de origen entomológico. Por último, se participó en el desarrollo de una herramienta informática para la gestión automatizada de evidencias entomológicas mediante una aplicación en la que el conocimiento generado es compartido de manera colaborativa. Esta herramienta gratuita consta de dos partes: una base de datos y una herramienta específica para el cálculo del intervalo postmortem a través de los grados-día acumulados, las curvas de crecimiento y los diagramas isomorfos, entre otros datos que pueden ser introducidos de manera manual o automática.

Molekulární markery pro detekci genetické variability přírodních populací forenzně významných druhů bzučivkovitých (Calliphoridae, Diptera)

KLOJDOVÁ, Martina January 2018 (has links)
This thesis was focused on suitability of selected molecular markers for detection of genetic variability of four species from the family Calliphoridae important in the forensic entomology. A set of eight markers, both mitochondrial (COI, ND6, CytB, CR) and nuclear (RP S12, RP S13, RP L12, PB2), were applied on samples from natural populations of representative species (Calliphora vicina, Lucilia caesar, Lucilia sericata, Phormia regina) most common in the Czech Republic. Level of detected variability was evaluated and compared, both with respect to the particular species as well as their geographic origin.

No. of bitstreams: 1 TAUHYL_Luis_Gustavo_2013.pdf: 16388420 bytes, checksum: 22a4e66470251df0d031f3ed7f9d2aec (MD5) Previous issue date: 2013-11-13 / Financiadora de Estudos e Projetos / The Family Calliphoridae is a diverse group of taxonomic, biogeographic, veterenary, forensic and medical importance, with more than 1200 species. The subfamily Toxotarsinae is endemic for the Neotropical region, has eleven species and is distributed mainly in the Andes countries and south of Brazil. Several authors have already studied this group and contributed with wide literature. The Toxotarsinae species are easily recognizable, but there are some difficulties to classify higher-specific taxa. This is the first phylogeny made for Toxotarsinae and it was necessary for better understanding of this group evolution. The aim of this work was to study the relationship among Toxotarsinae species through cladistics analysis. The character matrix was developed exclusively with morphological information. It was performed heuristic analisys using pacimony with equal weighting analyses obtained from Winclada and implied weighting obtained with TNT. The ingroup was compound for all Toxotarsinae species, Toxotarsus ambrosianus, T. nigrocyaneus, T. humeralis, S. chlorogaster, S. magellanica, S. dichroa, S. splendida, S. roraima, S. versicolor e S. maurii, and Neta chilensis, and the outgroup was compound by: Lucilia cuprina (Wiedemann, 1830), Calliphora nigribasis (Macquart, 1851) e Chrysomya megacephala (Fabricius, 1775). Equal weighting analysis resulted in only one most parsimoniously topology ((Sarconesia roraima + (Neta chilensis + S. magellanica)) + (S. splendida + (S. maurii + (S. versicolor + (S. dichroa + (S. chlorogaster + (Toxotarsus nygrocianeus + (Toxotarsus humeralis + Toxotarsus ambrosianus)))))))), with L=105, IC=58 e IR=71. Toxotarsinae appears as a monophyletic group, supported by nine synapomorphies. The ingroup species formed two branches: Sarconesia roraima+ supported by two synapomorphies, and S. splendida+ supported by ten synapomorphies. Implied weighting analysis resulted one tree, with different topologies with k values between 1 3. Based on the obtained topologies, the genus Sarconesia is polyphyletic and the other two genera, Neta and Toxotarsus, are among Sarconesia. The original Toxotarsus species remain togheter and supported by eleven synapomorphies at the apex of S. splendida+ clade. The taxa distribution in topology obligates the proposition of nomenclatural changes. Neta chilensis of S. roraima+ branch will be transferred to genus Sarconesia, and S. splendida+ branch will be transferred to Toxotarsus. An identification key was developed with the new combinations is presented. / A família Calliphoridae é um grupo de importância taxonômica, biogeográfica, veterinária, forense e médica e é composta por pouco mais de 1200 espécies. A subfamília Toxotarsinae é endêmica à região Neotropical, possui onze espécies e distribui-se, principalmente, nos países andinos e sul do Brasil. Vários autores já estudaram os Toxotarsinae, o que confere um amplo material de estudo. As espécies pertencentes a este grupo são facilmente reconhecidas, mas há certa dificuldade na classificação dos táxons supra-específicos, razão pela qual este estudo foi realizado. O objetivo do trabalho, portanto, foi o de estudar as relações de parentesco entre espécies de Toxotarsinae (Calliphoridae: Diptera) através de análise cladística. A matriz de caracteres foi desenvolvida exclusivamente com caracteres morfológicos. Foram realizadas análises heurísticas usando parcimônia com e sem pesagem nos programas Winclada e TNT, respectivamente. O grupo interno foi composto por todas as 11 espécies de Toxotarsinae, sendo três de Toxotarsus, Toxotarsus ambrosianus, T. nigrocyaneus e T. humeralis, sete de Sarconesia, S. chlorogaster, S. magellanica, S. dichroa, S. splendida, S. roraima, S. versicolor e S. maurii e uma do gênero monotípico Neta, Neta chilensis. O grupo-externo foi composto por três espécies: Lucilia cuprina (Wiedemann, 1830), Calliphora nigribasis (Macquart, 1851) e Chrysomya megacephala (Fabricius, 1775). A análise sem pesagem resultou em apenas uma topologia ((Sarconesia roraima + (Neta chilensis + S. magellanica)) + (S. splendida + (S. maurii + (S. versicolor + (S. dichroa + (S. chlorogaster + (Toxotarsus nygrocianeus + (Toxotarsus humeralis + Toxotarsus ambrosianus)))))))), com L=105, IC=58 e IR=71. Toxotarsinae aparece como um grupo monofilético, com suporte de nove sinapomorfias. As espécies foram agrupadas em dois ramos internos: Sarconesia roraima+ suportado por duas sinapomorfias e S. splendida+ por dez sinapomorfias. As análises com pesagem implícita resultaram em uma árvore, com mudanças na topologia apenas com valores de k entre 1 - 6. Com base nas topologias obtidas, tanto com como sem pesagem, o gênero Sarconesia apareceu como táxon polifilético, pois os dois outros gêneros, Neta e Toxotarsus, foram incluídos entre suas espécies. As espécies do gênero Toxotarsus permanecem juntas suportadas por onze sinapomorfias no ápice do clado S. splendida+. A distribuição dos táxons na topologia tem como consequência a proposição de alterações nomenclaturais. A espécie Neta chilensis será transferida para o gênero Sarconesia e as do clado S. splendida+ serão transferidas para o gênero Toxotarsus. Uma chave de identificação com as novas combinações é apresentada.

Interações interespecíficas e comportamentais de moscas-varejeiras : abordagens ecológicas e médico-legais envolvendo populações naturais /

Galindo, Luciane Almeida. January 2009 (has links)
Orientador: Wesley Augusto Conde Godoy / Resumo: As interações interespecíficas em dípteros califorídeos de importância forense resultam de processos biológicos complexos, envolvendo comportamentos específicos capazes de influenciar tanto a abundância como a diversidade de insetos presentes nos substratos orgânicos em decomposição. Nesse sentido, a presença de determinadas espécies com forte ação interativa, como por exemplo, predadores, competidores ou parasitóides, pode interferir substancialmente na composição da fauna decompositora de cadáveres, com sérias implicações para a estimativa de intervalo pós-morte em investigações criminais. Em estudo prévio foi investigado em laboratório o comportamento de oviposição em L. eximia, C. megacephala e C. albiceps na tentativa de esclarecer se a postura de ovos em moscas-varejeiras ocorre meramente ao acaso, ou se a presença prévia de diferentes espécies pode influenciar a desova por parte das espécies que chegaram ao local subsequentemente. Os resultados encontrados indicam que as espécies L. eximia e C. megacephala escolhem sítios de oviposição em que não há a presença prévia de larvas de C. albiceps, uma espécie predadora intraguilda. Esses resultados sugerem estudos mais aprofundados, preferencialmente em populações naturais, focalizando sobre a interação entre larvas e adultos de moscas-varejeiras, já que há evidências de que fêmeas adultas são capazes de detectar a presença de larvas predadoras, o que influi na decisão oviposicional. Este estudo teve o objetivo geral de investigar a abundância, diversidade e dinâmica comportamental em populações de moscas-varejeiras no contexto de recursos alimentares efêmeros e limitados, considerando a ação da predação intraguilda. A proposta do estudo é criar duas frentes de investigação no contexto de ecologia comportamental, experimentação em campo e modelagem matemática populacional / Abstract: The interspecific interactions in calliphorid flies of forensic impoltance result of complex biological processes, involving specific behaviors capable of influencing both the abundance and the diversity of insects in organic substrates in decomposition. The presence of certain species with a strong interactive action, such as predators, competitors or parasitoids, can interfere substantially in the composition of the decomposer fauna of corpses, with serious implications for the postmortem interval estimate in criminal inquiries. In a previous study the oviposition behavior in L. eximia, C. megacephala and C. albiceps was investigated in laboratory in the attempt to clarify if the egg laying in blowflies occurs at random, or if the previous presence of different species may influence the oviposition of the species that had arrived subsequently at the substrate. The results suggest that the species L. eximia and C megacephala prefer oviposition substrates, without the previous presence of C. albiceps larvae, an intraguild predator species. These results suggest further studies, preferably in natural populations, focusing on the interaction between larvae and adult of blowflies, since there is evidence that females are able to detect the presence of predator. This study had the general objective of investigating the abundance, diversity and behavioral dynamic in populations of blowflies in the context of limited and ephemeral food resources, considering the effect of intraguild predation. The proposal of the study is to create two fronts of investigation in the context of behavioral ecology, experimentation in field and population mathematical modeling / Mestre
