RESUMO
The prevalence of Salmonella spp. was investigated in 109 wild birds poached in the illegal wildlife trade in Rio de Janeiro; most of them are passerines from Thraupidae family and three from Psittacidae. One strain of Salmonella ser. Typhimurium and two strains of Salmonella ser. Panama were isolated from passerine species and all of them showed resistance to multiple antimicrobial drugs, like ampicillin, ceftriaxone, ceftiofur, tetracycline, gentamicin, nalidixic acid, ciprofloxacin, and enrofloxacin. PFGE showed 100% similarity among the Salmonella ser. Typhimurium strain isolated from a Temminck's seedeater (Sporophila falcirostris) and the strains isolated from a human outbreak, in southern Brazil. The two Salmonella ser. Panama strains isolated from two chestnut-capped blackbirds (Chrysomus ruficapillus) present in the same catch showed the same clonal origin and have never been associated with epizooties and human outbreaks. Potential for dissemination of resistant Salmonella through situations offered by captive management and the isolation of the same strain from wild birds and human sources may become a problem for the conservation of natural populations and to public health.

Em abril de 1988 e maio de 1990 foram isoladas 81 amostras de Neisseria gonorrhoeae de pacientes atendidos em laboratórios públicos e privados. Dentre os isolados, 54.32 por cento foram resistentes à penicilina, 43.21 por cento à ampicilina, 7.41 por cento à gentamicina e 69.14 por cento à tetraciclina. Três amostras produziram ß-lactamase, representando uma ocorrência de 3.7 por cento de Neisseria gonorrhoeae produtora de penicilinase na população estudada.
