Diagnosis and treatment of HEp-2 cells contaminated with mycoplasma

Braz. j. biol; 81 (1), 2021
Abstract Contamination of primary and cell cultures by mycoplasmas is one of the main economic and biological pitfalls in basic research, diagnosis and manufacture of biotechnological products. It is a common issue which may be difficult to conduct surveillance on. Mycoplasma presence may affect several ...

'Candidatus Mycoplasma haemoalbiventris' and tick-borne pathogens screening in white-eared opossums (Didelphis albiventris) from Curitiba and Foz do Iguaçu Cities, Paraná State, southern Brazil

Abstract Hemoplasmas are epierythrocytic bacteria that infect mammals. 'Candidatus Mycoplasma haemoalbiventris' was detected in white-eared opossums (Didelphis albiventris) from southern and central-western Brazil. The present study aimed at: i) screening opossums for tick-borne (TBP) pathogens (Piroplas...

Investigation of Mycoplasma spp. in birds of the Rio de Janeiro Zoo by isolation and PCR

Pesqui. vet. bras; 40 (3), 2020
Brazil is one of the countries with the most abundant avifauna in the world. The confinement of birds associated with close contact with other animals and humans favor the spread of agents of respiratory diseases. Among them, mycoplasmas can cause asymptomatic or apparent disease that manifests in birds ...

Survey of vector-borne and nematode parasites involved in the etiology of anemic syndrome in sheep from Southern Brazil

Abstract Although anemia has been historically linked to Haemonchus contortus infection, other infectious agents, such as hemotropic mycoplasmas and tick-borne disease pathogens, may also lead to anemic crisis in sheep. This study has aimed to investigate infections related to anemia in a sheep herd from...

Prevalence of ureaplasma urealyticum, mycoplasma hominis and human papillomavirus coinfection in people attending a sexually transmitted infections (STI)/HIV reference centre in Salvador, Bahia, Brazil

Introduction: Ureaplasma urealyticum and Mycoplasma hominis are frequently found at many women’s and men’s urogenital tract, and have been associated with non-gonococcal urethritis, cervicitis, infertility, chorioaminionitis and adverse pregnancy outcomes. Some studies show high prevalence of human p...

Molecular detection of vector-borne agents in cats in Southern Brazil

Abstract This study used serological and molecular methods to investigate the occurrence of vector-borne pathogens (VBP) with zoonotic potential in cats neutered at the University Veterinary Hospital in Canoinhas, Santa Catarina. The combined PCR and serological results revealed that 17 (56.6%) cats were...

Molecular detection of Bartonella, Ehrlichia and Mycoplasma in feral dogs of El Pedregal de San Angel Ecological Reserve in Mexico City

Abstract Free-ranging and feral dogs represent a group of unattended companion animals. They impact wild animal populations by predating native species, displacing predators and introducing exotic pathogens. The aim of this work was to describe the molecular occurrence of Rickettsia, Ehrlichia, Anaplasma...

Detection of Hemotropic Mycoplasma sp. in white-eared opossums (Didelphis albiventris) from Southern Brazil

Abstract Opossums are marsupials from the New World of the genus Didelphis and known as synanthropic animals due to their proximity with human beings. To date, 'Candidatus Mycoplasma haemodidelphis' has been solely found infecting the North American opossum (Didelphis virginiana). Accordingly, the aim of...

Bacteria isolated from the lower respiratory tract of sheep and their relationship to clinical signs of sheep respiratory disease

Pesqui. vet. bras; 39 (10), 2019
Respiratory diseases are among the most important diseases in sheep flocks. Herein was studied the bacterial etiology of respiratory disease and the clinical signs of 99 female and male sheep breed in the states of São Paulo (SP) and Rio de Janeiro (RJ), Brazil. After physical examination of animals, tr...

First molecular detection of Mycoplasma ovis (Hemotropic mycoplasmas) from Sheep in Brazil

Abstract Mycoplasma ovis is an emerging zoonotic pathogen with a worldwide distribution and can cause mild to severe hemolytic anemia, icterus, and poor weight gain in animals. Although M. ovis has been described in small ruminants worldwide, data on M. ovis in sheep in Brazil is unknown. The objective o...
