Introdução: A micoplasmose hemotrópica é uma doença causada por diferentes gêneros de Mycoplasma spp. como o caso do Mycoplasma haemofelis transmitido aos gatos pela picada de pulgas infectadas. Ao atingir o sistema circulatório do felino, o parasita se adere as hemácias, gerando resposta imune do hospedeiro levando a quadros de anemia hemolítica. Alguns felinos costumam ter anemia regenerativa como achado laboratorial devido a parasitemia causada pelo microrganismo, exceto em gatos positivos para FeLV. Os sinais clínicos são variáveis e incluem apatia, fraqueza, anorexia, mucosas pálidas, icterícias, no entanto alguns animais infetados são assintomáticos. É considerada uma doença oportunista. Objetivo: Realizar uma revisão de literatura sobre a doença abordando seus aspectos patogênicos, sinais clínicos, além dos métodos diagnósticos e os tratamentos comumente preconizados. Material e Métodos: Para a pesquisa bibliográfica foram acessados artigos científicos, publicados entre 2010 e 2021, utilizando os descritores “micoplasmose hemotrópica felina” e “hemobartonelose em gatos” nas plataformas digitais SciELO, Google Acadêmico e PubVet. Resultados: A doença possui como principal sinal clinico a anemia hemolítica em gatos imunocompetentes, em alguns casos, o hematócrito pode diminuir de repente colocando a vida do paciente em risco. A fisiopatologia dessa doença possui três estágios importantes: fase aguda, fase de recuperação e fase crônica. A infecção inicia-se com a fase aguda e os sinais clínicos neste período se manifestam de maneira leve, inaparentes. O diagnóstico se dar pela avaliação do esfregaço sanguíneo onde pode evidenciar o M. haemofelis em eritrócitos. A confirmação do diagnóstico também pode ser por meio de PCR. Para o tratamento utilizam-se antibióticos, sendo descrito na literatura preferencialmente o uso de doxiciclina, tetraciclina, oxitetraciclina, enrofloxacina, corticóides e fluidoterapia. A transfusão de sangue é realizada quando houver anemia grave. A terapia com corticoide suprime a hemólise imunomediada e a doxiciclina é efetiva contra o parasito. Conclusão: A infecção por M. haemofelis é considerada uma doença comum na medicina veterinária e se não tratada pode levar a morte do animal. Por se tratar de uma doença transmitida por picada de pulgas infectadas a melhor maneira de prevenir a doença é controlando os ectoparasitas permitindo que os animais tenham uma vida saudável.

Respiratory infections of sheep and goats cause heavy morbidity and mortality, leading to huge economic losses. Conventional methods of diagnosis that include isolation and identification of incriminating microbes are time-consuming and fraught with logistic challenges. Direct detection of incriminating microbes using molecular tools is gaining popularity in clinical, microbiological settings. In this study, a total of 50 samples (44 nasal swabs and 6 lung tissues) from sheep and goats were screened for the detection of different bacterial species by in vitro amplification of genus or species-specific genes. Histophilus somni was detected in 2% goat samples, Trueperella pyogenes in 20% goat nasal swabs, whereas 22% goat nasal swab samples were found positive for Mycoplasma spp. None of the samples from sheep was detected positive for H. somni, T. pyogenes, Mycoplasma spp. Similarly, all samples, irrespective, whether from sheep or goats, showed negative results for Pasteurella multocida, Mannheimia haemolytica, and Corynebacterium pseudotuberculosis.

Abstract The gopher tortoise (Gopherus polyphemus), a keystone species, is declining throughout its geographic range. Lack of knowledge with respect to the potential infectious diseases present within wild populations creates a dilemma for wildlife biologists, conservationists and public policy makers. The objective of this study was to conduct a health assessment of two previously unstudied gopher tortoise aggregations located at two sites in southeastern FL. Samples were collected from 91 tortoises (48 adults, 35 juveniles, 8 hatchlings) captured at Florida Atlantic University’s Harbor Branch Oceanographic Institute, in Fort Pierce, FL, USA in 2019, and Loggerhead Park in Juno Beach, FL, USA, during 2018–2019. Samples of blood, nasal swabs and oral/cloacal swabs were analyzed for hematology, plasma protein electrophoretic profiles and infectious disease testing including Mycoplasma spp. serology and polymerase chain reaction (PCR) assays for Ranavirus, Herpesvirus and Anaplasma spp. Hematological and plasma protein electrophoresis reference intervals are presented for adult and juvenile tortoises from both sites combined. Clinical signs consistent with upper respiratory tract disease (URTD) were observed in 18/91 (20%) tortoises, and antibodies to Mycoplasma agassizii were detected in 33/77 (42.9%) tortoises. Adult tortoises were significantly more likely than juveniles to have URTD clinical signs, and statistically significant, positive relationships were observed between the presence of antibodies to Mycoplasma spp. and carapace length, packed cell volume and plasma globulin concentrations. Anaplasma spp. inclusions were observed in 8/82 (10%) tortoises, but PCR detected Anaplasma sp. in 21/83 (25%) tortoises. Herpesvirus and Ranavirus were not detected in any blood or swab samples. This work contributes important baseline information on the health of gopher tortoises toward the southern end of the species’ range.

AbstractIn spring 2020, a severe disease outbreak with high morbidity and mortality was observed in a collection of 15 Horsfield’s tortoises (Testudo horsfieldii). Affected tortoises showed upper respiratory- and gastrointestinal tract signs, including rhinitis and stomatitis. Testudinid herpesvirus 1 (TeHV1) and Mycoplasma spp. were detected by PCR in oral swabs of affected animals. Histological examination of one deceased animal showed intranuclear inclusion bodies typical for herpesvirus infections in liver, spleen and oesophagus. The virus was likely introduced into the collection 2 years earlier by a clinically healthy Horsfield’s tortoise that was tested positive for TeHV1 by PCR.
