Pneumonia bacteriana em jabuti-piranga (Chelonoidis carbonaria): aspectos clínicos, microbiológicos, radiológicos e terapêutica / Bacterial pneumonia in red-footed tortoise (Chelonoidis carbonaria): clinical aspects, microbiological, radiological and therapeutic

A pneumonia é uma doença respiratória comum na clínica de répteis. Agentes infecciosos são capazes de causar pneumonia primária em répteis mantidos em cativeiro, porém na maioria dos casos, são secundárias a problemas de manejo, higiene e nutricionais. O objetivo desse trabalho foi relatar a ocorrência de pneumonia bacteriana em jabuti-piranga (Chelonoidis carbonaria), e descrever o diagnóstico clínico, microbiológico, radiográfico e a conduta terapêutica. O animal apresentava sinais de distúrbios respiratórios e foi descrito durante a anamnese que houve um diagnostico anterior de pneumonia. Os achados radiográficos foram sugestivos de pneumonia/edema pulmonar. Baseado nos exames radiográficos e sinais clínicos apresentados iniciou-se o tratamento com administração de Cloranfenicol (40mg/kg/SID/IM) por 10 dias. Foram isoladas Klebsiella spp. e Citrobacter spp. da cultura bacteriana realizada da coleta de lavado endotraqueal. Ambas com perfil de resistência múltipla aos antibióticos testados. Instituiu-se protocolo terapêutico utilizando Gentamicina (5mg/kg/IM), em sete aplicações com intervalos de 72h. Após o segundo protocolo terapêutico notou-se melhora dos sinais clínicos do animal, porém foi observada a persistência de secreção nasal. Foi realizado novo exame radiográfico, demonstrando discreta diminuição na opacidade do campo pulmonar direito e nenhuma alteração significativa no campo pulmonar esquerdo na projeção craniocaudal. Devido à permanência do sinal clínico apresentado, nova coleta de material endotraqueal foi realizada, e houve isolamento de Citrobacter spp. e Enterobacter spp. A partir dos resultados obtidos no antibiograma, instituiu-se novo protocolo com uso de amicacina (2,5mg/kg/IM), em sete aplicações com intervalos de 72h. Após antibioticoterapia, outro exame radiológico foi realizado, e demonstrou redução satisfatória do quadro pulmonar, e sinais clínicos...

Pneumonia is a common respiratory disease in clinical of reptiles. Infectious agents are capable of causing primary pneumonia in reptiles maintained in captivity, but in most cases are secondary to problems of management, hygiene and nutrition. The aim of this study was to report the occurrence of bacterial pneumonia in red-footed tortoise (Chelonoidis carbonaria), and describe the clinical, microbiologic, radiographic and therapeutic management. The animal showed signs of respiratory disorders and has been described in the clinical history before diagnosis of pneumonia. The radiographic findings were suggestive of pneumonia/pulmonary edema. Based on the displayed radiographic examination and clinical signs began treatment with administration of chloramphenicol (40mg/kg/SID/IM) for ten days. Were isolated Klebsiella spp. and Citrobacter spp. bacterial culture done collecting endotracheal lavage. Both with multiple antibiotic resistance profile tested. Treatment protocol was instituted using gentamicin (5mg/kg/IM) applications into seven intervals of 72h. There was improvement in clinical signs of the animal, but the presence of nasal secretion was still observed. New radiographic examination, demonstrating slight decrease in the opacity of the right lung field and no significant change in the left lung field in craniocaudal projection was performed. Because of the persistence of clinical signs presented new collection endotracheal material was performed, and there was isolation of Citrobacter spp. and Enterobacter spp. From the results obtained in the antibiogram, was instituted new protocol with the use of amikacin (2.5mg/kg/IM) applications into seven intervals of 72h. After antibiotic therapy, other radiological examination was performed, and showed satisfactory reduction in pulmonary function and clinical signs...

Vitamin A deficiency enhances the effects of 7-12 demethylbenz [A] anthracene [DMBA] induced skin carcinogenesis in albino rats

The present study was designed to see the effects of vitamin A deficiency in DMBA induced chemical carcinogenesis on skin of albino rats. The rats were kept on vitamin A deficient diet for 20 weeks and treated with 20 micro g/0.2ml of DMBA twice weekly. After 20 weeks 70% skin lesions were developed in animals taking vitamin A deficient diet [VAD] alone, while 90%skin lesions were seen in animals receiving VAD, DMBA group, however, 10-20% more skin lesions were seen in normal diet, DMBA and VAD DMBA group as compared to vad group. The results indicate that vitamin A deficiency enhances the effect of chemical carcinogenesis
