Independentemente dos resultados encontrados, foram coletadas amostras de leite para análises microbiológicas e de contagem de células somáticas (CCS). O isolamento microbiológico foi realizado em ágar sangue de ovino 5% e em ágar MacConkey, com 72 horas de incubação em aerobiose a 37oC. Foram procedidas, a cada 24 horas, leitura e identificação dos isolamentos. A ocorrência de quadros de mastite clínica foi representada por um único caso (0,14%) entre os 735 quartos mamários analisados, ocorrendo na fase inicial da lactação e envolvendo microrganismos de origem ambiental (Morganella morganii, Enterobacter aerogenes). Foram considerados quadros de mastite subclínica aqueles com resultados positivos ao CMT acompanhados de exame microbiológico positivo. A freqüência observada de quadros de mastite subclínica entre os 734 quartos mamários estudados foi de 20,03%, dos quais isolou-se principalmente microrganismos contagiosos. Os resultados negativos ao CMT predominaram durante todo o estudo (69,07%), independente da fase de lactação ou estação do ano consideradas, tendo sido observados resultados positivos do exame microbiológico em 57,58% das amostras CMT negativas. Foi elevada a freqüência de microrganismos classificados como contagiosos entre as amostras de leite analisadas, independente da estação do ano e da fase de lactação, entre os quais prevaleceu o Corynebacterium spp. (47,67%), entre os 579 microrganismos pertencentes a 19 gêneros bacterianos crescidos em cultura pura ou em associação. Considerando-se a falta de homogeneidade entre as variâncias, as contagens de células... / A total of 735 mammary quarters from buffalo cows were submitted to inspection, palpation, strip cup test and California Mastitis Test (CMT) in order to diagnose clinical and subclinical mastitis. Independent of the observed results, milk samples were collected from each mammary quarter to microbiological exams and automatic somatic cell counts (SSC). Milk samples were inoculated in 5% ovine blood agar and MacConkey agar and incubated for 72 hours under 37oC and aerobic condition. Growth observations and identifications were performed every 24 hours. One (0,14%) out of 735 mammary quarters studied presented clinical mastitis. It occurred in first stage of lactation (0 to 60th day post calving) and environmental microorganisms were isolated (Morganella morganii, Enterobacter aerogenes). Mammary quarters presenting positive results to CMT and microbiological exams were considered as subclinical mastitis cases and these represented 20,03% among 734 studied samples. CMT negative results were the most frequent observed during the study (69,07%), independent of lactation stage or season of the year considered. Among these CMT negative milk samples, 57,58% were positive in microbiological exams. There was a high occurrence of contagious microorganisms among the 579 identified bacteria from 19 different genus, isolated in pure or in association. Corynebacterium spp. was the most prevalent (47,67%), in every lactation stage or season of the year. Considering the absence of a normal distribution, somatic cell counts were submitted to a logarithmic transformation, log2(CCS/100)+3, originating the transformed somatic cell count (TSCC). There were statistically significant differences between TCCS means from milk samples with positive (2,23) and negative (1,71) results to CMT. Such differences were also observed in milk...

Resumo: Sabendo-se do grande potencial dos bubalinos como produtores de carne e da importância da análise das fibras musculares para a caracterização da qualidade da carne, objetivou-se neste estudo avaliar as isoformas da miosina de cadeia pesada (MyHC) e os tipos de fibras dos músculos Longissimus dorsi (LD) e Semitendinosus (ST) de 28 bubalinos Mediterrâneo não-castrados e a possível modulação de acordo com os diferentes pesos de abate (450, 480, 510 e 540 kg). Amostras dos músculos foram coletadas e submetidas às técnicas de eletroforese (SDS-PAGE), m-ATPase e NADH-TR. Foram analisadas a porcentagem relativa das isoformas de MyHC, assim como, frequência, área e diâmetro das fibras musculares. Constatou-se que bubalinos Mediterrâneo não possuem a isoforma MyHC IIb, apresentando somente três isoformas de MyHC (IIa, IIx/d e I), cujas porcentagens não variaram significativamente (P > 0,05) entre os pesos de abate. A presença de fibras musculares híbridas (IIA/X) nos músculos LD e ST permitiu a classificação dos tipos de fibras pela atividade contrátil, em fast e slow. Para ambos os músculos, a frequência foi maior para as fibras fast em todas as categorias avaliadas, porém houve diferença (P < 0,05) na frequência dos tipos de fibras dos músculos LD e ST de acordo com os pesos de abate. Os animais abatidos aos 540 kg obtiveram maiores valores para área e diâmetro das fibras, tanto para o LD quanto para o ST. O músculo ST apresentou maiores valores de área e diâmetro que o músculo LD para todos os pesos de abate avaliados, revelando o crescimento mais tardio. / Abstract: Knowing of the great productive potential of the water buffalo as meat producer and of the importance of the research of muscle fiber types for the characterization of the meat quality, the aim of the study was to evaluate Myosin Heavy Chain Isoforms (MyHC) and the muscle fiber types of Longissimus dorsi (LD) and Semitendinosus (ST) muscles of 28 Mediterranean buffaloes not-castrated and its possible modulation according with the different slaughter weights (450, 480, 510 and 540 kg). Samples of the muscles were collected and submitted the electrophoresis (SDS-PAGE), m- ATPase and NADH-TR techniques. The relative percentage of isoforms MyHC were measured, as well as, frequency, area and diameter of muscle fiber types. The absence of MyHC IIb isoform in Mediterranean buffaloes was evidenced, which had only three MyHC isoforms (IIa, IIx/d and I), whose percentage had not varied significantly (P > 0.05) between the slaughter weights. The presence of hybrid fibers (IIA/X) in muscles LD and ST allowed to the classification of the fiber types for a contraction activity, in fast and slow. For both muscles, the frequency was higher for fiber fast in all the evaluated categories, however had differences (P < 0.05) in the frequency of muscle fiber types LD and ST in the slaughter weights evalueted. The animals of slaughter weight 540 kg showed higher values for area and diameter of the fibers, as much for the LD as well as the ST. Muscle ST presented greater values of area and diameter then muscle LD for all slaughtered weights evaluated, disclosing the more delayed growth. / Orientador: André Mendes Jorge / Coorientador: Maeli Dal Pai Silva / Banca: Cristiana Andrighetto / Banca: José Roberto Sartori / Mestre
