The aim of this work was to study the correlation between intake and deposition of fatty acids in the Longissimus muscle of Nellore steers supplemented at pasture. The fieldwork was implanted in an area of 52 ha, formed of Brachiaria brizantha. Forty Nellore steers with initial average weight of 373.7 ± 14.9 kg and 26 months of age were used. The animals were distributed into four treatments: Control= T00 (supply only mineral salt), T03= Supply of concentrate in the amount of 0.3 % of Body Weight; T06= Supply of concentrate in the amount of 0.6 % of Live Weight , T09= Supply of concentrate in the amount of 0.9 % of live weight. Samples of concentrates and forages were collected for fatty acids analysis. The experiment lasted for 98 days. After this period the animals were slaughtered. Longissimus samples were vacuum packed and frozen for analysis of fatty acid composition. The results were statistically analyzed by estimating Pearson linear correlation coefficients. The results showed that there are correlations between the fatty acids consumed and fatty acids deposited in the muscle.

Objetivou-se estudar a correlação entre consumo e deposição de ácidos graxos no músculo Longissimus de novilhos nelore suplementados em pastagens. O trabalho de campo foi implantado numa área de 52 ha, formada de Brachiaria brizantha. Foram utilizados 40 novilhos da raça Nelore com peso inicial médio de 373,7 ± 14,9 kg e 26 meses de idade, distribuídos em quatro tratamentos: Controle= T00 (fornecimento apenas de sal mineral), T03= fornecimento de 0,3% concentrado em função do peso vivo; T06= fornecimento de 0,6 % concentrado em função do peso vivo; T09= fornecimento de 0,9 % concentrado em função do peso vivo. Amostras dos concentrados e da forragem foram coletadas para análise da composição de ácidos graxos. O período experimental foi de 98 dias. Após este período, os animais foram abatidos. Os resultados foram analisados por correlação linear de Pearson e teste t. Constatou-se que existem correlações entre os ácidos graxos consumidos e depositados no músculo.

Enteropathogenic Escherichia coli (EPEC) strains are important agents of infantile diarrhea all over the world, gaining even greater importance in developing countries. EPEC have also been isolated from various animal species, but most isolates belong to serotypes that differ from those recovered from humans. However, it has been demonstrated that several isolates from non-human primates belong to the serogroups and/or serotypes related to those implicated in human disease. The objective of this study was to evaluate the genetic differences between thirteen strains isolated from non-human primates and the same number of strains isolated from human infections. Human isolates belonged to the same serogroup/serotype as the monkey strains and the evaluation was done by analysis of random amplified polymorphic DNA. Dendrogram analysis showed that there was no clustering between human and monkey strains. Human and non-human isolates of the EPEC serotypes O127:H40 and O128:H2 shared 90 and 87% of their bands, respectively, indicating strong genomic similarity between the strains, leading to the speculation that they may have arisen from the same pathogenic clone. To our knowledge, this study is the first one comparing genomic similarity between human and non-human primate strains and the results provide further evidence that monkey EPEC strains correlate with human EPEC, as suggested in a previous investigation.

The occurrence of serum antibodies to Borrelia burgdorferi in professionals in close contact with wild animals was determined. Seventy eight technicians workers coming from two São Paulo public institutions housing wild animals had their blood collected (serum samples). All samples were submitted to ELISA for IgM and IgG antibodies against Borrelia burgdorferi. The results showed five positive (6.4%), two suspect (2.6%) and 71 negatives (91%) samples. Based on positive results it is concluded that the infection level is higher to that detected in the general population and similar to values of endemic areas, concluding that this assessed population could be considered at risk for Lyme disease.

Relata-se infecção septicêmica em cobras d’água (Helicops modestus) causada por Proteus vulgaris. Os animais iniciavam o processo apresentando abscessos puntiformes de coloração esbranquiçada na pele e após rápida evolução, morriam (100% de mortalidade). Descreve-se, ainda, a sensibilidade do P. vulgaris isolado dos animais a drogas antibacterianas.

As dermatomicoses dos animais domésticos constituem zoonoses importantes, urna vez que estes mantêm estreito contato com a espécie humana, dada a alta infectividade observada nesses processos. Relata-se a ocorrência de sete surtos de dermatomicoses, um por M. gypseum envolvendo um gato e um indivíduo do sexo feminino e os outros por M. canis envolvendo 20 indivíduos da espécie humana (adultos, jovens e crianças de ambos os sexos), 5 cães, 16 gatos e um macaco gibão (Hylobates lar).

Dermatomycosis in domestic animals are important zoonosis in view of the fact that they maintain close contact with human beings. Seven ringworm outbreaks are here described, one of M. gypseum involving a cat and a women and the remainder of M. canis involving 20 human beings (adults, young people and children), 5 dogs, 16 cats and a gibbon-monkey (Hylobates lar).
