| The objective of the present trial was to characterize genetically strains of Campylobacter jejuni subsp. jejuni isolated from humans and several animal sources (bovines, swine, dogs, primates, wild boars and poultry). A total of 828 different animal samples (feces, carcass, aborted fetus and hysterectomized uterus) were analysed by means of routine bacteriological methods, and 36 C. jejuni strains were isolated. Thirty strains of human fecal origin were obtained in clinical analysis laboratories in the city of São Paulo. The 66 C. jejuni strains isolated were submitted to genetic characterization. Primers based on fla A gene were used in a polymerase chain reaction (PCR) and amplified a fragment of the 702 bp. PCR products were evaluated by means of... |

| A total of 192 samples of illegal cheese from different regions of the states of São Paulo and Minas Gerais, Brazil, were analyzed for the isolation and detection of Brucella spp. DNA by means of microbiological culture and polymerase chain reaction (PCR), respectively. Samples that yielded positive results were submitted to the analysis of the occurrence of Brucella abortus (biovars 1, 2 e 4), as well as to the differentiation of DNA in B19 vaccinal strain or Brucella abortus field strain using PCR. Although the microorganism was not isolated from any sample, PCR detected 37 positive samples (19.27%) using genus-specific primers. From these, all (100%) were Brucella abortus. Differentiation of the strain showed that 30/37 samples (81.08%) were vaccinal... |

| Leptospirosis is a widely distributed zoonosis that affects domestic and wild animals, and that has the man as the end point of its epidemiological chain. Leptospirosis diagnosis in primates is more difficult than in other animal species, as clinical signs and lesions are less evident and antibody response is detected only for short periods. The aim of this article was to describe the detection of Leptospira spp using polymerase chain reaction (PCR), in clinical samples from one captive black-capped Capuchin monkey (Cebus apella), which presented characteristics compatible with leptospirosis (jaundice and haemorrhagic kdney) in the macroscopic post-mortem examination. A friable kidney fragment and urine sample were cultured and submitted to experimental... |
