Enteric bacteria are considered important potential pathogens in avian clinical medicine, causing either primary or opportunistic infections. The aim of this study was to evaluate the frequency of enterobacteria in the intestinal microbiota of psittacine birds and to determine the antimicrobial susceptibility of the Escherichia coli isolates cultured. Fecal samples were collected from 300 parrots captured from the illegal wildlife trade in Goiás, Brazil and were processed using conventional bacteriological procedures. A total of 508 isolates were obtained from 300 fecal samples: 172 E. coli (33.9% of isolates; 57.3% of individuals); 153 Enterobacter spp. (30.1% of isolates; 51.0% of individuals); 89 Klebsiella spp. (17.7% of isolates; 29.7% of individuals); 59 Citrobacter spp. (11.6% of isolates; 19.7% of individuals), 21 Proteus vulgaris (4.2% of isolates; 7.0% of individuals), 5 Providencia alcalifaciens (0.98% of isolates; 1.67% of individuals), 5 Serratia sp. (0.98% of isolates; 1.67% of individuals), 3 Hafnia aivei (0.59% of isolates; 1.00% of individuals), and 1 Salmonella sp. (0.20% of isolates; 0.33% of individuals). Escherichia coli isolates were subsequently tested for susceptibility to the following antibiotics: amoxicillin (70.93% of the isolates were resistant), ampicillin (75.58%), ciprofloxacin (23.25%), chloramphenicol (33.14%), doxycycline (64.53%), enrofloxacin (41.28%), tetracycline (69.19%), and sulfonamide (71.51%). Multi-resistance to three and four groups of antibiotics occurred in 40 samples (23.25%) and 4 samples (2.32%), respectively. These results demonstrate that illegally traded birds are carriers of potentially pathogenic bacteria, including E. coli strains with antimicrobial resistance.
Resumo:A raiva é uma enfermidade infectocontagiosa que afeta mamíferos, inclusive o homem. Estima-se que a raiva dos herbívoros seja responsável por enormes prejuízos econômicos na América Latina. O morcego hematófago Desmodus rotundus é o principal transmissor do vírus rábico (VR). Este estudo teve como objetivo avaliar a evolução do diagnóstico laboratorial para raiva animal em cinco espécies animais, na série cronológica 1990-2010, na microrregião Quirinópolis, Goiás, Brasil. Para avaliação da distribuição dos casos diagnosticados foram utilizados resultados de diagnóstico laboratorial, realizados pelo Laboratório de Diagnóstico da Agência Goiana de Defesa Agropecuária. A partir destes, foi construído um banco de dados com as variáveis: município de origem do animal, resultado, mês e ano. Das 116 amostras analisadas, 9% (10) foram positivas para oVR e 91% (106) negativas. Todos os resultados positivos foram provenientes de bovinos. Dentre os municípios da microrregião, Itarumã apresentou maior número de casos positivos e Caçu enviou mais amostras. Houve tendência de aumento no envio de amostras e no número de exames laboratoriais. Também houve tendência ao aumento de diagnósticos positivos. Amostras da espécie bovina foram as mais analisadas, seguida de morcegos hematófagos. Em relação à época do ano, foram observados mais casos positivos no período da seca. Palavras-chave: Animais domésticos; epidemiologia; quirópteros; vírus rábico. Abstract:Rabies is an infectious contagious disease that affects mammals, including humans. Herbivore rabies is estimated to be the cause of major economic downturns in Latin America. The hematophagous bat Desmodusrotundus is the main transmitter of the rabies virus. The present study aimed at evaluating the laboratory diagnosis of animal rabies in five species of animals, in the 1990-
