Dioctophymosis in a free-ranging maned wolf (Chrysocyon brachyurus): clinical-therapeutic, ultrasonographic and pathological aspects - case report / [Dioctofimose em um lobo guará (Chrysocyon brachyurus) de vida livre: aspectos clínico-terapêuticos, ultrassonográficos e patológicos - relato de caso]

Dioctophymosis is the disease caused by Dioctophyma renale, a large nematode, popularly known as giant kidney worm, and whose definitive hosts are the domestic dog and many wild mammal species. There are some reports of maned wolf parasitism by D. renale, however, in most cases the reports are restricted to the finding of the parasite during necropsy, without clinical assessment. The present report aimed to describe the clinical-therapeutic, ultrasonographic and pathological aspects of D. renale parasitism in a free-ranging maned wolf, emphasizing the treatment with an association of doramectin, praziquantel, pyrantel pamoate, and febantel that resulted in complete elimination of the parasite.(AU)

A dioctofimose é a doença causada pelo Dioctophyma renale, um nemátodo grande, popularmente chamado de verme gigante do rim e que tem como hospedeiro definitivo o cão doméstico e inúmeras espécies de mamíferos silvestres. Existem alguns relatos do parasitismo do lobo-guará por D. renale, contudo, na maioria das vezes, os relatos se restringem apenas ao achado do parasita durante a necropsia, sem a correlação clínica. O presente relato objetiva descrever os aspectos clínico-terapêuticos, ultrassonográficos e patológicos do parasitismo por D. renale em um lobo-guará de vida livre, enfatizando o tratamento com uma associação de doramectina, praziquantel, pamoato de pirantel e febantel, o que resultou na eliminação completa do parasita.(AU)

Performance and Serum Biochemical Profile of Broiler Chickens Supplemented with Piper Cubeba Ethanolic Extract

Piper cubeba is an Asian pepper used in popular medicine for its known antimicrobial, antiparasitic, and anti-inflammatory actions. The study evaluated the effects of dietary inclusion of Piper cubeba ethanolic extract (PE) as a replacement for anantibiotic growth promoter (AGP) on the performance and biochemical serum profile of 1- to 21-d-old broilers (Cobb®). Two hundred one-d-old broilers were housed in experimental battery cages and distributed in a completely randomized design. The following treatments were applied: negative control (NC) - basal diet; positive control (PC) - basal diet with addition of AGP; and the basal diet with inclusion of 0.17%, 0.34%, and 0.52% of PE (NCE1, NCE2, and NCE3, respectively). Growth performance, biochemical serum profile and internal organ weights were evaluated. Birds fed the AGP presented higher feed intake compared with the other treatments (p 0.05). The PC, NC, and NCE1 treatments presented higher weight gain compared with those fed NCE2 and NCE3 (p 0.05). The NC, NCE1, and NCE2 diets promoted better feed conversion ratio than the PC and NCE3 (p 0.05). Lower triglyceride serum levels were determined in broilers fed the NC and NCE1 diets. Amylase serum levels were lower in NCE1 and NCE2 treatments compared with the NC (p 0.05), whereas those obtained with the PC and NCE3 diets were not different (p>0.05) from the others. Organ relative weights were not influenced by the treatments. The inclusion of 0.17% of PE did not compromise the growth performance, biochemical serum profile or organ relative weights of 21-d-old broilers.(AU)
