Molecular survey of hemotropic mycoplasmas in crab-eating raccoons (Procyon cancrivorus) in southern Brazil.

Hemoplasmas are non-cultivable bacterial parasites of erythrocytes that infect domestic and wild animals, as well as humans. Their means of transmission and pathogenesis remain contentious issues and difficult to evaluate in wild animals. Procyon cancrivorus is a South American carnivore and occurs in all Brazilian biomes. In this study, we aimed to investigate occurrences of hemoplasmas infecting P. cancrivorus and to identify their 16S rRNA gene, in southern Brazil. DNA was extracted from spleen and blood samples of P. cancrivorus (n = 9) from different locations. Hemoplasma DNA was detected in six samples, based on 16S rRNA gene amplification and phylogenetic analysis. Four of the six sequences belonged to the "Mycoplasma haemofelis group", which is closely related to genotypes detected in Procyon lotor from the USA; one was within the "Mycoplasma suis group", closely related to "Candidatus Mycoplasma haemominutum"; and one was within the intermediate group between these clusters. Thus, these sequences showed that the molecular identity of hemoplasmas in the population studied was very variable. In five positive animals, Amblyomma aureolatum ticks and a flea (Ctenocephalides felis felis) were collected. The present study describes the first molecular detection of mycoplasmas in P. cancrivorus.

Os micoplasmas hemotrópicos (hemoplasmas) são parasitas bacterianos não-cultiváveis de eritrócitos que infectam tanto animais domésticos e selvagens, como seres humanos. A transmissão e a patogênese são discutíveis e difíceis de avaliar em animais selvagens. O mão pelada (Procyon cancrivorus) é um carnívoro Sul-americano, que ocorre em todos os biomas brasileiros. O objetivo do presente estudo é o de investigar a ocorrência de hemoplasmas infectando P. cancrivorus e identificar seu gene 16S rRNA no Sul do Brasil. O DNA foi extraído do baço e amostras de sangue de P. cancrivorus (n= 9). O DNA de hemoplasma foi detectado em seis amostras, com base na amplificação do gene 16S rRNA e na análise filogenética. Quatro das seis sequências pertencem ao "Grupo Mycoplasma haemofelis", que estão intimamente relacionadas aos genótipos detectados no Procyon lotor dos EUA; uma dentro do "Grupo Mycoplasma suis", que está intimamente relacionado ao "Candidatus Mycoplasma haemominutum", e uma dentro do grupo intermediário entre esses clusters, mostrando assim que há uma diversidade genética de hemoplasmas na população estudada. Em cinco animais positivos, foram coletados carrapatos Amblyomma aureolatum e uma pulga Ctenocephalides felis. O presente estudo traz a primeira detecção molecular de micoplasmas em P. cancrivorus.(AU)

Slaughter condemnation in bovine due to parasitic lesions and their economic impact in Federal Inspection System establishments in Brazil and in State inspection System in Rio Grande do Sul State.

Slaughter condemnations are important sources of information on cattle health. The incidence of bovine parasitic diseases is still very high in Brazil. These diseases, in addition to causing harm to the animals health, are neglected zoonotic diseases in several parts of world. The study analysed not only the Carcass losses, but also the economic damage resulting from slaughter condemnations due to parasitic causes. Cattle slaughter data from the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA), over the period of 2012 to 2015 and data from the Secretary of Livestock and Irrigation of the state of Rio Grande do Sul (SEAPI-RS) were analyzed between 2014 and 2018.The number of organs and carcasses condemned was multiplied by the respective values (in Brazilian Real) obtained from slaughterhouses and subsequently converted into dollars. Brazilian analysis in SIF (Federal Inspection System) establishments showed that more than 1.2 million organs (3,884,505 kg) and 20,000 carcasses (4,547,718 kg) were condemned only due to parasitic causes during post-mortem inspection. In Rio Grande do Sul, in state inspection establishments, more than 1.7 million organs (8,210,559 kg) and 5,000 carcasses (1,243,200 kg) were condemned. These data are alarming and support the need for public policies to control these parasitic diseases.

Abstract Slaughter condemnations are important sources of information on cattle health. The incidence of bovine parasitic diseases is still very high in Brazil. These diseases, in addition to causing harm to the animals health, are neglected zoonotic diseases in several parts of world. The study analysed not only the Carcass losses, but also the economic damage resulting from slaughter condemnations due to parasitic causes. Cattle slaughter data from the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA), over the period of 2012 to 2015 and data from the Secretary of Livestock and Irrigation of the state of Rio Grande do Sul (SEAPI-RS) were analyzed between 2014 and 2018.The number of organs and carcasses condemned was multiplied by the respective values (in Brazilian Real) obtained from slaughterhouses and subsequently converted into dollars.

Resumo Condenações durante o abate são importantes fontes de informação sobre a sanidade dos rebanhos. Ainda são altas as incidências de doenças parasitárias, as quais trazem consequências à saúde dos animais, são zoonoses e têm sua importância negligenciada em diversos países. O estudo objetivou quantificar não apenas as perdas encontradas, mas o prejuízo econômico resultante das condenações ao abate por causas parasitárias. Para isso foram analisados dados de abate de bovinos do Ministério da Agricultura Pecuária e Abastecimento, no período de 2012 a 2015, e dados da Secretaria da Agricultura Pecuária e Irrigação, do estado do Rio Grande do Sul, no período de 2014 a 2018. A quantidade de órgãos e carcaças condenados foi multiplicada pelos respectivos valores (em Reais), obtidos da indústria frigorífica e, posteriormente, convertidos para dólar. A análise brasileira de estabelecimentos com SIF (Serviço de Inspeção Federal) mostrou que mais de 1,2 milhão de órgãos (3.884.505 kg) e 20 mil carcaças (4.547.718 kg) foram condenados devido a causas parasitárias durante a inspeção. No estado do Rio Grande do Sul, nos estabelecimentos de inspeção estadual, foram condenados mais de 1,7 milhão de órgãos (8.210.559 kg) e 5 mil carcaças (1.243.200 kg). Os dados são alarmantes e ressaltam a necessidade de políticas públicas para controlar estas parasitoses.
