Enterobacterial colonization in captive red-eared sliders (Trachemys scripta elegans).

The handling of turtles and other reptiles can be associated with risk of pathogenic enterobacteria transmission, mainly Salmonella spp. The aim of this study was to identify the enterobacteria in cloacal swabs of 39 red-eared sliders (Trachemys scripta elegans). Cloacal swabs from 39 captive individuals were analyzed. After sample enrichment in brain-heart infusion broth and 1% peptone water, bacterial isolation was performed through cultivation in blood, MacConkey and xylose lysine desoxycholate agar. Bacterial identification was achieved through conventional tests and automated turbidity analysis. The results indicated the growth of Kluyvera ascorbata (38/39), Leclercia adecarboxylata (37/39), Raoultella planticola (30/39), Citrobacter freundii (20/39), Proteus spp. (15/39), and Escherichia coli (5/39). Salmonella spp. were not detected. The intestinal enterobacteria identified inthis study differed from that reported in the literature for other reptiles.

An outbreak of chlamydiosis in captive blue-fronted Amazon parrots (Amazona aestiva) in Brazil.

Fifty-eight blue-fronted Amazon parrot (Amazona aestiva) nestlings, recovered from the illegal trade, became ill at a wildlife rehabilitation center in São Paulo State, Brazil. Clinical signs observed were nonspecific, and the mortality rate was 96.5% despite initial treatment with norfloxacin. Postmortem examinations were performed on 10 birds. Liver and spleen smears showed structures suggestive of Chlamydophila psittaci in four cases. Diagnosis was confirmed by seminested polymerase chain reaction on tissue samples. Other birds from the same location showed no clinical signs of the disease, although high complement fixation titers to C. psittaci were found in 10 adult psittacines. All birds in the facility were treated with doxycycline. The two surviving nestlings did not recover after two doxycycline treatments and were euthanatized. The high mortality rate observed in this outbreak was attributed to poor conditions of husbandry and delays in the diagnosis and treatment of the disease. After diagnosis, improved control measures for chlamydiosis were instituted.
