“…Dentre as espécieS de rã, a rã-touro se destaca por ser a principal espécie cultivada, devido aos seus índices zootécnicos. Mesmo sendo considerada uma espécie exótica, ela possui qualidades nutritivas, sabor suave e semelhantes as carnes brancas como frango e peixe (SARTURI, 2021;NASCIMENTO et al, 2019).…”

A carne de rã-touro possui baixo teor de colesterol, baixa quantidade de gorduras saturadas e alto teor de cálcio e proteínas. Características essa que fazem com que a carne de rã-touro, seja recomendada para o tratamento de algumas doenças. O presente trabalho visa determinar parâmetros bromatológicos e microbiológicos de linguiça a base de carne de rã-touro. De forma a cumprir esse objetivo, foram realizadas duas formulações, para formulação 1 (F1), com 36,23% de carne de rã-touro, 15,85% de carne suína, 45,29% de toucinho, e formulação 2 (F2), com 64,00% de carne de rã-touro, 16,19% de carne suína e 16,19% de toucinho. Os teores de umidade, proteína e cinzas, nas formulações não apresentaram diferença significativa entre si, somente teor de lipídios, que apresentou diferença entre as duas formulações, devido a presença de uma concentração maior de toucinho na formulação 1, quanto as análises microbiológicas, as duas formulações apresentaram ausência de contaminação, indicando boas condições de higiene e manipulação da matéria prima ou do produto final. Conclui-se que as linguiças de carne de rã, elaboradas e analisadas no presente estudo, se enquadram nos padrões da legislação vigente, apresentando características tecnológicas adequadas, demonstrando sua viabilidade comercial.

Spring viremia of carp virus (SVCV) is a rhabdovirus that primarily infects cyprinid finfishes and causes a disease notifiable to the World Organization for Animal Health. Amphibians, which are sympatric with cyprinids in freshwater ecosystems, are considered non-permissive hosts of rhabdoviruses. The potential host range expansion of SVCV in an atypical host species was evaluated by testing the susceptibility of amphibians native to the Pacific Northwest. Larval long-toed salamanders Ambystoma macrodactylum and Pacific tree frog Pseudacris regilla tadpoles were exposed to SVCV strains from genotypes Ia, Ib, Ic, or Id by either intraperitoneal injection, immersion, or cohabitation with virus-infected koi Cyprinus rubrofuscus. Cumulative mortality was 100% for salamanders injected with SVCV, 98–100% for tadpoles exposed to virus via immersion, and 0–100% for tadpoles cohabited with SVCV-infected koi. Many of the animals that died exhibited clinical signs of disease and SVCV RNA was found by in situ hybridization in tissue sections of immersion-exposed tadpoles, particularly in the cells of the gastrointestinal tract and liver. SVCV was also detected by plaque assay and RT-qPCR testing in both amphibian species regardless of the virus exposure method, and viable virus was detected up to 28 days after initial exposure. Recovery of infectious virus from naïve tadpoles cohabited with SVCV-infected koi further demonstrated that SVCV transmission can occur between classes of ectothermic vertebrates. Collectively, these results indicated that SVCV, a fish rhabdovirus, can be transmitted to and cause lethal disease in two amphibian species. Therefore, members of all five of the major vertebrate groups (mammals, birds, reptiles, fish, and amphibians) appear to be vulnerable to rhabdovirus infections. Future research studying potential spillover and spillback infections of aquatic rhabdoviruses between foreign and domestic amphibian and fish species will provide insights into the stressors driving novel interclass virus transmission events.
