Pasteurelosi aviária 1. Pasteurella anatipestifer - descrição de um surto em aves

Abstract

A Pasteurella anatipestífer outbreak is described in different domestic fowl species. High morbidity and mortality; nervous symptoms and diarrhoea; central nervous system congestion and fibrinous serosity was observed. Peripferical blood and tracheo-bronchic secretion smears showed Gram negative cocobacili with bipolar stain. Peripherical blood culture in chicken blood agar showed characteristical colonies from Gram negative cocobacili with bipolar stain. Motility and biochemical finding confirmed P. anatipestifer. In vitro test with amicacin, streptomicyn, penicilling, gentamicin, cloramphenicol, sulfazotrin, furaltadone, lincomycin, showed sensitive, while tetracycline, neomycin and sulfametroprim, resistance. The oxytetracycline in drinking water helped in the control of this outbreak. The clinical, anatomopathologic, epidemical finding, isolation and identification, differential diagnostic and therapeutics methods are discussed.
