Molecular analysis of the N gene of canine distemper virus in dogs in Brazil

Eleven central-nervous-system samples collected from stray dogs between 2000 and 2004 were found positive by RT-PCR, which amplified a 480bp fragment of the N gene of canine distemper virus (CDV). Phylogenetic analysis based on partial N-gene sequences showed four major clusters. All dog strains segregated into cluster I, with a mean nucleotide identity of 95.8% and 95.6% with the Onderstepoort and Lederle vacc...

Prevalence of virulence factors in Escherichia coli strains isolated from the g...

The prevalence of virulence genes expressing fimbriae, production of hemolysin, colicin and aerobactin, was determined in Escherichia coli isolates from healthy cow’s genital tract not showing clinical signs of infection. The presence of fimbriae expression genes (pap, sfa, afa) was assayed using specific primers in a polymerase chain reaction; none were detected in any of the isolates. Yet, a prevalence of 90....

Occurrence of toxigenic Escherichia coli in raw milk cheese in Brazil

The occurrence of toxigenic Escherichia coli in raw milk cheese was surveyed in Middle Western Brazil. Fifty samples of cheese from different supermarkets were analyzed for E.coli. The isolates were serotyped and screened for the presence of verotoxigenic E. coli (VTEC) and enterotoxigenic E. coli (ETEC) by Polymerase Chain Reaction (PCR). The susceptibility to thirteen antimicrobial agents was evaluated by the...

Virulence factors of Escherichia coli isolated from diarrheic calves

One hundred seventy-three Escherichia coli strains isolated from calves from northwestern São Paulo State, having diarrhea were examined for the production of thermolabile (LT) and thermostable (ST) enterotoxins and for the presence of virulence factors associated with bovine colibacillosis. Eighty-five (49.1%) of the E.coli strains produced toxins; 53 isolates were detected as producing STa toxin, and 9 also p...

A twenty-year survey of dermatophytoses in Braga, Portugal

Modifications in social habits together with the increase of emigration have contributed not only to increased dermatophytoses but also to an altered etiology. During the last few years, Braga has suffered a radical change from a rural to a cosmopolitan life-style.
