Severe enteritis in dogs associated with single and mixed infections
2024
Overview
Infectious enteritis is highly prevalent among dogs worldwide and, in some cases, it can be fatal. This study describes the clinical and laboratorial findings of single and mixed infections associated with severe enteritis in 76 dogs from Southern Brazil. Intestinal segments and/or fecal samples were subjected to histopathology and molecular detection of DNA viruses, bacteria and protozoa. Severe intestinal lesions were observed in most cases. Single infections were detected in 52.6% of cases, double (36.8%) and triple (10.5%) infections were also identified. Carnivore protoparvovirus 2 (CPV-2) was the most frequent agent in single infections (36.8%). Coinfection by CPV-2 and Giardia spp. was the most common in dual infections (19.7%), followed by CPV-2 and Cryptosporidium spp. (10.5%). The most frequent triple infection was CPV-2, Giardia sp. and Cryptosporidium spp. (6.6%). Our results shown that single and mixed infections are associated with severe enteritis in dogs in southern Brazil, mainly involving CPV-2 and Giardia sp. RESUMO: Enterites infecciosas são altamente prevalentes entre cães em todo o mundo e, em alguns casos, podem ser fatais. Este estudo descreve os achados clínicos e laboratoriais de infecções simples e mistas associadas a enterites graves em 76 cães do sul do Brasil. Segmentos intestinais e/ou fezes foram submetidos à análise patológica e detecção molecular de vírus de genoma DNA, bactérias e protozoários. Lesões intestinais severas foram observadas na maioria dos casos. Infecções únicas foram detectadas em 52,6% dos casos, e infecções duplas (36,8%) e triplas (10,5%) também foram identificadas. O Protoparvovírus carnívoro 2 (CPV-2) foi o agente mais frequente nas infecções simples (36,8% do total). Coinfecção por CPV-2 e Giardia sp. foi a mais comum em infecções duplas (19,7%), seguido por CPV-2 e Cryptosporidium spp. (10,5%). A tripla infecção mais frequente foi CPV-2, Giardia spp. e Cryptosporidium spp. (6,6%). Nossos resultados demostraram que infecções simples e mistas estão associadas a enterites graves em cães no sul do Brasil, envolvendo principalmente CPV-2 e Giardia sp.
