ABSTRACT
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...

En la región central de Argentina, las características epidemiológicas y moleculares de las infecciones por Chlamydophila pneumoniae en reptiles son desconocidas. Para detectar C. pneumoniae, se usó la reacción en cadena de la polimerasa anidada que amplifica el gen rpoB en muestras de hisopado cloacal de 19 reptiles. Once (57,89 %) reptiles resultaron positivos. La secuenciación y el análisis filogenético corroboraron la presencia de esta bacteria. No se detectó ADN de C. pneumoniae en la faringe ni IgM anti-C. pneumoniae en el suero de los cuidadores; sin embargo, ellos presentaron títulos muy elevados de IgG anti-C. pneumoniae. La detección de ADN de C. pneumoniae en los reptiles demostró la circulación de este agente en el centro recreativo donde se realizó este estudio, lo que podría explicar la exacerbada respuesta inmunitaria en los cuidadores; este hallazgo sugiere la presencia de un potencial ciclo zoonótico. Se reporta aquí por primera vez la detección de C. pneumoniae en reptiles en Argentina
In the central area of Argentina, the epidemiological and molecular characteristics of Chlamydophila pneumoniae infections in reptiles are still unknown. A nested polymerase chain reaction of the rpoB gene was used to detect C. pneumoniae in cloacal swab samples from 19 reptiles at a recreational area. Eleven (57.89%) reptiles were positive; the sequencing and phylogenetic analysis confirmed the presence of this bacterium. Neither C. pneumoniae DNA in the caregivers'pharynges nor IgM antibodies anti-C. pneumoniae in their serum samples were detected; however, caregivers presented very high titers of IgG anti-C. pneumoniae. The detection of C. pneumoniae DNA in reptiles demonstrated the circulation of this agent in the recreational area and could be responsible for the exacerbated immune response of the personnel handling the reptiles, which suggests a potential zoonotic cycle. This is the first report of the detection of C. pneumoniae in reptiles in Argentina
