Aufgrund einer hohen Rate von Nierenveränderungen in einem bayrischen Schlachtunternehmen, welche jedoch nicht immer zum Ausschluss des jeweiligen Organs führten, war das Ziel dieser Arbeit, den Anteil an makroskopisch veränderten bzw. unveränderten sowie für untauglich zum menschlichen Verzehr bewerteten Nieren von Schlachtschweinen im Rahmen der Fleischuntersuchung zu erheben. Darüber hinaus sollten die Veränderungen sowohl der tauglichen als auch der untauglichen Nieren mittels pathologisch-anatomischer Untersuchung charakterisiert werden. Um zukünftige Entscheidungen bezüglich „tauglich/untauglich“ am Schlachtband zu erleichtern, erfolgte an ausgewählten typischen Läsionen eine histopathologische Untersu-chung zur Verifizierung der makroskopischen Diagnose. Des Weiteren sollte eine makroskopische und histo-logische Charakterisierung des „Status quo“ einer Schweineniere im Jahre 2012 anhand dieser Stichprobe unternommen und mit Beschreibungen in der Literatur verglichen werden. Im Untersuchungszeitraum (zwei mal fünf Tage im Juli und August 2012) wurden die Nieren von insgesamt 6235 Schlachtschweinen (120-130 kg) aus dem „Einzugsgebiet Oberbayern“ untersucht. Weitere 98 Nieren dienten als Kontrolle und der Charakterisierung einzelner Veränderungen. Am Schlachtband wurden 12 237 Nieren nach äußerer Adspektion in die Gruppen „ohne besonderen makroskopischen Befund“ (o.b.B.), „Ein-ziehungen im Bereich der Nierenrinde mit und ohne Beteiligung der Kapsel“ (E.R.m./o.K.) ohne Berücksichti-gung weiterer, eventuell zusätzlich vorliegender Befunde, „Vorliegen einer persistierenden fetalen Lappung“ (p.f.L.) und „sonstige Befunde“ unterteilt. Eine ausführliche pathologisch-anatomische Untersuchung erfolgte an insgesamt 2010 von den amtlichen Fachassistenten untauglich bewerteter Nieren. 400 Proben wurden histopathologisch mittels H.-E.-Färbung und teils unter Anwendung von Spezialfärbungen (PAS-Reaktion, Movat-Versilberung, Azan-Färbung) sowie immunhistochemischer Methoden (CD3, CD79a, MAC387, Lami-nin, PCV-2-Antigen) beurteilt. Dabei erfolgte sowohl die Charakterisierung der makroskopisch sichtbaren Läsionen, als auch die Befundung angrenzender, makroskopisch unauffälliger Parenchymanteile. Daneben standen die Daten über Konfiskatabzüge bei Lungen, Herzen und Lebern der Tiere zur Verfügung. An 75,35 % aller Nieren konnten makroskopische Befunde erhoben werden, wobei 16,91 % der Organe un-tauglich beurteilt wurden. 70,52 % der 10 168 tauglichen Nieren zeigen bei der äußeren Adspektion Läsionen (64,93 % E.R.m./o.K.; 3,10 % p.f.L.; 2,49 % sonstige Befunde). Während die Rate untauglicher Nieren zwi-schen den Untersuchungswochen (UW) vergleichbar war (15,96 % bzw. 17,90 %) traten zwischen den Un-tersuchungstagen (UT) deutliche Abweichungen (9,70 %–26,96 %) auf. Ähnliches wurde bei den tauglichen Nieren ohne einen makroskopischen Befund beobachtet (17,67 %–37,59 % pro UT bzw. 28,33 % 1. UW und 19,81 % 2. UW). Der Anteil an Schweinen mit zusätzlichen Konfiskatabzügen bei Lunge, Herz und/oder Le-ber war bei Tieren mit mindestens einer untauglichen Niere bzw. zwei tauglichen Organen nahezu gleich groß (25,62 % bzw. 23,72 %), bei solchen mit zwei tauglichen o.b.B.-Nieren betrug er 29,19 %. 2010 näher unter-suchte Nieren wiesen in 0,35 % keinen, in 21,59 % einen bzw. in 78,26 % mehr als einen (bis zu sechs) unterschiedliche Befunde auf. Bis auf das Vorliegen von Nephrosen, akuter Glomerulonephritiden sowie einiger Entwicklungsstörungen konnten alle in der Literatur beschriebenen Nephropathien der Schweineniere nachgewiesen werden. Trotz identischem makroskopischem Bild variierten die histologischen Befunde bei ausgewählten Veränderungen. Die häufigsten Läsionen untauglicher Nieren waren E.R.m.K. (bei 72,09 %), welche sich histologisch als in Binde- und Fettgewebe eingebettete arterielle, venöse und Lymphgefäße dar-stellten und am ehesten als Missbildungen zu betrachten sind. Die bei 33,88 % beobachteten E.R.o.K. zeig-ten histologisch eine Fibrose oder eine chronische interstitielle (interst.) Nephritis, wobei vermutlich prä- und postnatale Insulte an der Entstehung beteiligt waren. An schlachtungsbedingte Petechien erinnernde Herde auf der Rindenoberfläche stellten sich in 96,8 % als entzündungsassoziierte Blutungen um teils alterierte Gefäße dar. Die unterschiedlichen Formen einer nicht-eitrigen interstitiellen Nephritis (multifokal, diffus, teils mit Fibrose) konnten makroskopisch bei ca. 13,5 % der untauglichen Nieren beobachtet werden, wobei histo-logisch teils die in der Literatur beschriebenen „Entzündungspattern“, aber auch teilweise kein histomorpho-logisches Korrelat nachgewiesen werden konnte. Während die makroskopische Diagnose einer embolisch-eitrigen Herdnephritis (0,1 %) und Pyelonephritis (0,2 %) sicher gestellt werden konnte, bereitete die einer solitären Pyelitis Schwierigkeiten. Makroskopisch als akute/subakute sowie chronische „infarktähnlich“ ange-sprochene Läsionen (bei insgesamt 9,66 %) wiesen nicht das klassische histologische Bild eines Infarktes auf, sondern passen zum Teil zu vaskulopathiebedingten „Subinfarkten“ oder stellten sich als fokale interst. Nephritiden dar. In makroskopisch unveränderten Nieren (Kontrollnieren) bzw. in unveränderten Bereichen veränderter Nieren (untaugliche, taugliche veränderte Nieren) zeigten über 96 %, unabhängig vom makro-skopischen Befund, eine graduell variable mononukleäre interstitielle Nephritis. Der Nachweis von tertiärem lymphatischen Gewebe („Follikel“) schwankt, abhängig vom makroskopischen (Haupt-)Befund der Niere, zwischen 0 % und 85 % (Kontrollnieren 30 %). Darüber hinaus zeigten ca. 78 % aller Proben eine Proliferation der Mesangiumzellen und/oder Endothelzellen sowie 100 % aller Proben eine graduell variable Sklerose und/oder Hyalinose („Minimal Change Nephrotic Syndrome“). Es kann festgestellt werden, dass das in der anatomischen Literatur beschriebene makroskopische Bild der Schweineniere nur in ca. 25 % aller Nieren an diesem Schlachthof vorliegt. Bezüglich der Entscheidung „tauglich/untauglich“ am Schlachtband erweist sich die pathologisch-anatomische Untersuchung als ausrei-chend und nötig. Hinsichtlich einer exakten pathologischen und ätiologischen Diagnose sind dieser Methode jedoch Grenzen gesetzt. Die histologischen Untersuchungen zeigen, dass von dezenten nicht-eitrigen interst. Nephritiden und Pyelitiden in nahezu jeder Niere am Schlachthof auszugehen ist, was, zusammen mit den glomerulären Veränderungen und dem Auftreten des tertiären lymphatischen Gewebes, für eine chronische Immunstimmulation bzw. für subklinische Infektionen der untersuchten Schweine spricht. Von einem Ge-sundheitsrisiko für den Verbraucher dürfte beim Großteil der Läsionen nicht auszugehen sein, doch zeigt die Unsicherheit in der fleischhygienerechtlichen Bewertung angeborener oder degenerativer Defekte die Not-wendigkeit eines „Positivkataloges“ für Organe von Schlachttieren. Ob und inwieweit diese interst. Nephritis in Zukunft lebensmittelrechtlich relevant wird, bleibt abzuwarten. Diese Arbeit sollte Anlass zu aktuellen ver-gleichenden Studien geben, um regionale, epidemiologische und genetische Einflüsse auf bestimmte Läsio-nen zu untersuchen, wie sie durch NIEBERLE und COHRS (1970) vor Jahrzehnten durchgeführt wurden.

Para tal avaliação adotou-se o programa estatístico R utilizando-se o método estatístico de correlações de Pearson.

The dissertation investigates an interface between industrial architecture, the public realm and formal and informal programmatic functions mediated through an urban abattoir. Further, the dissertation examines the occupation of a deserted industrial site and revival thereof through new light industrial programming. The proposal focusses on the rejuvenation of the abattoir as a ritualistic and cognisant process and the contemporary application of the industrial typology mediated through regenerative architectural principles and sustainable technologies. A new public interface is explored to reconnect industrial architecture and industry to the “urban surface”, avoiding the mistakes of the past and preserving the future of the site and its surrounding context. The final design ameliorates the deserted wasteland condition by connecting the new abattoir to the industrial heritage of the site. The resultant design is an urban abattoir which interacts and expresses itself at various scales whilst always representative of the processes housed. The design creates a dialogue between the public and the abattoir by adopting the methodology of reclaiming the entire animal carcass as done in South African ritual slaughter. The design incorporates numerous sustainable systems to reduce the waste found in abattoirs. The project reconnects the contemporary abattoir to the productive urban network and emphasises the importance of architecture in the regeneration of a building typology.

The aim of this study was to determine the levels of cadmium (Cd) and lead (Pb) in livers and kidneys of cattle slaughtered at Grootfontein abattoir in Namibia. The study design was based on the epidemiological principles to detect a single animal whose kidneys or liver contained Cd or Pb residues. The Grootfontein area of Namibia has extensive base-metal ore reserves, which were and are still extracted and processed in localities used as livestock pastures. Namibia is also an arid country which predominantly uses borehole water for livestock and human consumption. These underground water bodies share the same space as base-metal ores. The anthropogenic activities in this area under the existing geological and hydrogeological circumstances offer opportunities for Cd and Pb to enter the food chain. Entry of Cd and Pb in the food chain leads to bioaccumulation in cattle kidneys and livers to concentrations above Codex Alimentarius Commission (CAC) standards, creating a possible public health risk. The CAC withdrew the maximum limit (ML) of 1mg kg-1 Cd in bovine kidneys and liver, but it has a provisional tolerable monthly intake (PTMI) of 0.025mg kg-1 human body weight. This CAC PTMI translates to a total exposure of 1.5mg Cd for a 60kg body weight person. The CAC ML for Pb in bovine offal is 0.5mg kg-1, while its provisional tolerable weekly intake (PTWI) of 0.025mg kg-1 human body weight is under review. This investigation intended to establish if Cd and Pb in the livers and kidneys of cattle slaughtered in the study area exceeded CAC human exposure limits. Liver and kidney specimens were collected from 31 randomly sampled mature cattle (estimated over five years old based on incisor teeth examined post slaughter). The specimens were analysed at a local mine laboratory, which was the only facility available and capable of performing the tests. They were digested using wet-ashing (the oxidation procedure). All liver digestates were analysed, while one kidney analyte was insufficient. Cd and Pb were measured using flame atomic absorption spectroscopy (FAAS). The detection limit (DL), which was the minimum metal concentration FAAS could measure was 0.2mg kg-1 for Cd and 1.1mg kg-1 for Pb. The laboratory could not refine the Pb DL which was more than twice the CAC ML. All livers had Cd concentrations below 0.2mg kg-1. One discarded kidney specimen was assigned a concentration below DL for analysis purposes. The Cd concentrations in 12 kidney specimens were below 0.2mg kg-1, between 0.288 and 1.221mg kg-1 in 16 and above 1.5mg kg-1 (2.6 - 3.64mg kg-1) in 3 specimens. The mean renal Cd concentration for the population (0.71±0.96mg kg-1) was statistically lower than 1.5mg kg-1 (p <0.05). Cd was therefore shown to be a chemical hazard for consumers of kidneys and a potential environmental hazard in the study area. Pb was negative in all of the 31 liver specimens, while in all the 30 kidney specimen digestates it was detected at concentrations below 1.1mg kg,-1. This result confirmed the presence of Pb as a potential chemical hazard found in bovine kidneys. However, a more sensitive analytical method was required to assess Pb food chain and public health hazard parameters in the study area. An epidemiological investigation of the study area using geographical information systems (GIS) to explore geographical factors that could have influenced exposure to Cd and Pb was done. While proximity to operational and decommissioned mining ventures appeared to result in higher mean renal Cd concentrations, the influence was not statistically significant. Feedlot rearing also appeared to cause higher mean renal Cd concentrations but the impact was also not statistically significant. It was concluded that Cd and Pb were chemical environmental contaminants which enter the animal and human food chain in the study area. A kilogram of bovine kidney-meat from approximately one in ten cattle (9.7%) carried more than 1.5mg Cd, exceeding the recommended CAC total dietary exposure for a 60-kg man. A mathematical model was used to estimate the risk of cattle with renal Cd concentration exceeding 1.5mg kg,-1, the expected number of cattle affected and the weight of meat entering the food chain. The estimated cattle population affected monthly was 5.95%, with a range of between 5 and 11 (mean = 8±4) cattle. These cattle were estimated to yield 8 to 18 (mean 13±6) kg bovine kidney-meat per month. A WHO standard-weight man who consumes a kilogram of kidney meat in this category in a month risks exposure to Cd doses beyond the CAC PTMI. The epidemiological triad of interactions between the host (cattle), agent (Cd and Pb) and the environment (proximity to mines) was used in order to suggest risk mitigation options. Recommendations from this study included advocacy on Cd and Pb in the food chain and developing partnerships with mining entities so that risk mitigation and communication can be better coordinated. Consumers are advised to reduce their monthly intake of kidney meat as this organ tissue has higher levels that those in other bovine organs and tissues. The cattle in the study were mature breeding animals (>5 years) and it is likely that this factor increased the risk of higher levels in kidneys as temporal determinants for bioaccumulation of Cd are important. The kidneys of younger animals would thus be less likely to contain significant Cd levels. Lastly, use of mathematical modelling, to translate research findings into quantitative estimates useful for public health safety programs, is recommended. / Dissertation (MMedVet)--University of Pretoria, 2012. / Paraclinical Sciences / unrestricted

This dissertation is a contribution to the ethnography of contemporary indigenous reindeer pastoralism in Norway: specifically, to the study of the neglected fields of reindeer killing and slaughtering practice. Its central contention is that in recent decades, the proliferation of human powers vested in the conduct of reindeer slaughter has created new conditions for practice, placing the identities of reindeer and herders at stake in new and still only dimly conceptualized ways. By exploring these, the dissertation aims to broaden existing debates concerning the so-called modernization of pastoral practice in Norway, drawing attention to some of its neglected aspects and inscribing them in a new register. Two principal strands inform the theoretical framework: one, approaches to the social study of knowledge that emphasise its practical, non-verbal and material aspects; and two, Foucauldian concepts of biopower as these may – or may not – be applicable to the human management of animal life.Individual chapters examine, in turn: the local politics of space on the Varanger peninsula, focusing particularly on links between the spatial management and the killing of reindeer; the practices and social relations of slaughter as it is conducted at the round-up corral; the social effects of the introduction of slaughterhouses, and of the regime of which they form a part; controversies surrounding specific slaughtering techniques and instruments, particularly the curved knife; and the politics of animal welfare discourse and practices in their application to reindeer herding. Finally, using the figure of animal sacrifice as a guiding trope, the concluding chapter attempts to situate some key aspects of the modernization of reindeer slaughter in relation to the operation of broader sacrificial economies that regulate the destruction of life at aggregate or populational levels. / Research Council of Norway

Depuis quelques années et dans plusieurs pays, un nouveau type de Staphylococcus aureus résistant à la méthicilline (SARM), le séquence type (ST) 398, a été fréquemment retrouvé chez les porcs et chez les fermiers en contact avec ces porcs. Au Canada, très peu d’informations sont disponibles concernant le SARM d’origine porcine. Une première étude dans notre laboratoire a permis de récolter 107 isolats de SARM provenant de deux abattoirs porcins du Québec. Le présent travail vise à caractériser les gènes de virulence et de résistance aux antibiotiques de ces SARM, d’étudier leur formation de biofilm en relation avec la spécificité du groupe agr et de vérifier la localisation plasmidique et la transférabilité de ces gènes à des souches de SARM d’origine humaine. Plusieurs souches ont démontré différents patrons phénotypiques de résistance aux antibiotiques. Vingt-quatre souches représentatives de ces isolats ont été soumises à une caractérisation plus approfondie par une étude génotypique en utilisant une biopuce à ADN et un grand nombre de gènes de virulence a été détecté codant pour des entérotoxines staphylococcales, des leucocidines, des hémolysines, des auréolysines, des facteurs d’immunoévasion, des superantigènes, des facteurs d’adhésion et des facteurs impliqués dans la formation de biofilm. Des gènes de résistance envers les aminoglycosides, les macrolides, les lincosamides, les tétracyclines et les biocides ont été également détectés par biopuce et leur localisation plasmidique a par la suite été déterminée. La transférabilité de ces gènes de souches porcines à des souches de SARM d’origine humaine a été démontrée par conjugaison bactérienne; ainsi le transfert horizontal de certains gènes de résistance aux antibiotiques et de virulence a été observé. Ces travaux de recherche apportent une meilleure connaissance de la résistance aux antibiotiques et de la virulence des SARM d’origine porcine et de leur potentiel de contribution à l’émergence de certaines résistances et facteurs de virulence chez le SARM d’origine humaine. / In recent years and in several countries, a new type of methicillin-resistant Staphylococcus aureus (MRSA), the sequence type (ST) 398, has been frequently found in pigs and in farmers in contact with these pigs. In Canada, little information is available concerning MRSA from pigs. A previous study in our laboratory identified 107 MRSA isolates from two pig slaughterhouses in Quebec. This study was conducted to determine antimicrobial resistance and virulence genes of MRSA from abattoir pig, to study their biofilm formation in relation with agr specificity groups and to evaluate horizontal transfer of genes to a MRSA of human clinical origin. Different phenotypic patterns of antimicrobial resistance were observed in these MRSA and a representative subset of these isolates was selected for further characterization. Twenty-four porcine MRSA were characterized by a DNA microarray, the StaphyType of CLONDIAG. Our results demonstrated that the MRSA strains from the abattoirs contain several antimicrobial resistance genes responsible for macrolide and tetracycline resistance and virulence genes encoding staphylococcal enterotoxins, hemolysins, leukocidins, aureolysin, superantigens, immunoevasion, adhesion, and biofilm development. This study presents the first evidence that horizontal transfer of some of these genes can occur between MRSA of porcine and human origin. We also report for the first time biofilm formation in Livestock Associated-MRSA of porcine origin associated with agr group II. It is possible that biofilm formation favors colonization, persistence as well as zoonotic potential. This research provides a better understanding of antimicrobial resistance and virulence of MRSA from pigs and their potential contribution to the emergence of some resistance and virulence factors in MRSA of human origin.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The data presented in this thesis resulted from the gross and histopathological interpretation of lesions found in cattle slaughtered for human consumption. The survey for lesions in slaughtered cattle was started in 2011. During the two years of the M.Sci. program the survey was focus in parasitic lesions, which were reported and discussed in the M.Sci. dissertation. The remaining lesions are included in the present thesis and were surveyed in a prospective study (2011-2016) carried out at the Laboratório de Patologia Veterinária at the Universidade Federal de Santa Maria (LPV-UFSM). The purpose of the study describe the gross and microscopical morphology lesions found in cattle in slaughterhouses in order to help veterinary meat inspectors and pathologists alike in identifying lesions found in the carcass and viscera of cattle at meat inspection. During the survey, 540 lesions were observed in cattle at slaughterhouses from different locations in the State of Rio Grande do Sul, Brazil. Seventeen of those were toxic lesions; 65 were neoplastic; 117 were parasitic and 164 were classified as sundry, which included, among others, lesions provoked by improper proceedings during the slaughter (so called technopathies ), lesions with little or no clinical importance. The current study resulted in four scientific papers which are included in the thesis: (1) Atypical cases of actinomycosis in cattle; (2) Granulomatous lesions found in cattle slaughtered for meat production; (3) Mixed apocrine adenocarcinoma of the tail in a cow and (4) Tumors found in cattle from slaughterhouses. / Esta tese envolveu o estudo das lesões macro e microscópicas encontradas em bovinos abatidos para consumo e é o resultado de colheita e interpretação de lesões iniciadas em 2011. Durante o período de mestrado (2012-2014) realizou-se o levantamento das lesões parasitárias, que foram abordadas na Dissertação. As demais lesões serão abordadas nesta tese. Esse estudo prospectivo (2011-2016) foi realizado no Laboratório de Patologia Veterinária da Universidade Federal de Santa Maria (LPV-UFSM) e teve como objetivo descrever macro e microscopicamente as lesões de bovinos encontradas em abatedouros frigoríficos, a fim de auxiliar médicos veterinários responsáveis pelo serviço de inspeção, bem como patologistas veterinários, a identificar lesões encontradas em carcaças e vísceras dos bovinos abatidos. Durante esse período, 540 lesões foram observadas em bovinos de abatedouros frigoríficos de diferentes regiões do Rio Grande do Sul. Dessas, 17 foram lesões de origem tóxica; 65 neoplásicas; 117 parasitárias; 177 infecciosas e 164 foram classificadas como outras lesões , que incluíam lesões ocasionadas por falhas durante o abate (tecnopatias), lesões sem significado clínico importante, entre outras. Este estudo resultou em quatro trabalhos científicos: (1) Actinomicose atípica em bovinos; (2) Lesões granulomatosas encontradas em bovinos abatidos para consumo; (3) Mixed apocrine adenocarcinoma of the tail in a cow e (4) Tumores em bovinos encontrados em abatedouros frigoríficos. Esses quatros trabalhos estão anexados a esta tese.
