First molecular detection of Coxiella burnetii in Brazilian artisanal cheese: a...
Rozental,Tatiana; Faria,Letícia Scafutto De; Forneas,Danielle; Guterres,Alexandro; Ribeiro,João Batista; Araújo,Flábio RibeiroABSTRACT Background: Global publications on Q fever have increased after the 2007 epidemic in the Netherlands. However, the epidemiology of Q fever/coxiellosis in Brazil is still poorly understood. Accordingly, there have been few studies investigating the presence of Coxiella burnetii in dairy products around the world, especially in Brazil, where consumption of fresh cheese made from raw-milk is very high. Ob...
Analysis of anti-tuberculosis drug resistance and sociodemographic and clinical...
Bonin,Camilla Resende; Fochat,Romário Costa; Leite,Isabel Cristina Gonçalves; Pereira,Thamiris Vilela; Fajardo,Marina de OliveiraABSTRACT Objective To determine the occurrence of anti-tuberculosis drug resistance and its association with sociodemographic and clinical characteristics of patients in a referral hospital. Methods This was a cross-sectional study based on data from patients who had mycobacterial culture identified and defined antimicrobials sensitivity profile (June 2014 to February 2016). The descriptive statistical analysis...

Validation of a real-time PCR assay for the molecular identification of Mycobac...
Sales,Mariana L.; Fonseca Júnior,Antônio Augusto; Orzil,Lívia; Alencar,Andrea Padilha; Silva,Marcio Roberto; Issa,Marina AzevedoMycobacterium tuberculosis is the major cause of tuberculosis in humans. This bacillus gained prominence with the occurrence of HIV, presenting itself as an important opportunistic infection associated with acquired immunodeficiency syndrome (AIDS). The current study aimed to develop a real-time PCR using Eva Green technology for molecular identification of M. tuberculosis isolates. The primers were designed to...
Autochthonous canine visceral leishmaniasis in a non-endemic area: Bom Sucesso,...
Silva,Marcio Roberto; Marques,Marcos José; Romanha,Alvaro José; Santa-Rosa,Idael Christiano de Almeida; Carneiro,Cláudia M.; Reis,Alexandre BarbosaThe article begins by describing a dog with characteristic symptoms of visceral leishmaniasis. A serum sample from this animal was positive by indirect immunofluorescence (IIF) performed in anti-Leishmania total IgG in 1999. Tissues from the same dog were also positive by polymerase chain reaction (PCR) in 2004, identifying Leishmania DNA in the cerebellum, liver, kidney, and intestine. This is the first report...
