Abstract Human papillomavirus (HPV) infection is common in sexually active women and viral persistence may cause intraepithelial lesions and eventually progress to cervical cancer (CC). The present study aimed to investigate epidemiological factors related to HPV infection and to evaluate viral persistence and CC precursor lesions frequencies in women from a city in the countryside of South Brazil. Three hundred women were recruited from a primary public health care clinic. The patients were interviewed and underwent sampling with cervical brushes for HPV-DNA detection/typing by a PCR-based assay and cytological analysis by Pap smear test. HPV was detected in 47 (15.7%) women. HPV infection was significantly associated with young age (<30 years) and low...

METHODS: Analysis of published DNA sequence of mucosal HPV types to select sequences of new primers. Design of an original nested-PCR assay using the new primers pair selected and classical MY09/11 primers. HPV detection and typing in cervical samples using the nested-PCR-RFLP assay. RESULTS: The nested-PCR-RFLP assay detected and typed HPV in cervical samples. Of the total of 128 clinical samples submitted to simple PCR and nested-PCR for detection of HPV,...

ABSTRACT Introduction: Nontyphoidal Salmonella serotypes are the main cause of human food-borne infection, including several hospitalization cases in the developing countries. Aim: To detect the main serotypes and to characterize the antibiotic resistance of human non-enteric and enteric nontyphoidal Salmonella from clinical isolates in Brazil. Methods: Salmonella serotypes were identified by microbiological and molecular methods. Susceptibility testing to antibiotics was performed by agar disk diffusion. Real-time PCRs were carried out for the detection of the genus Salmonella as well as serotypes Typhimurium and Enteritidis. Results: A total of 307 nontyphoidal Salmonella were isolated from 289 different patients in a reference laboratory (LACEN-RS)...

ABSTRACT Background Hepatitis B virus (HBV) infection is a major public health problem in Brazil. HBV endemicity is usually moderate to low according to geographic regions, and high prevalence of this virus has been reported in people of some specific Brazilian counties, including those with a strong influence of Italian colonization in southern Brazil. Analysis of HBV diversity and identification of the main risk factors to HBV infection are necessary to understand hepatitis B epidemiology in these high prevalence regions in southern Brazil. Objective To investigate epidemiological characteristics and HBV genotypes and subgenotypes circulating in a specific city with high HBV prevalence. Methods A cross-sectional study was performed with 102 HBV...

Mycoplasma gallisepticum (MS) and Mycoplasma synoviae (MS) are important avian pathogens and cause economic losses to the poultry industry. Molecular biology techniques are currently used for a rapid detection of these pathogens and the adoption of control measures of the diseases. The aim of this study was to develop and validate a technique for simultaneous detection of MG and MS by multiplex real time polymerase chain reaction (PCR). The complete assay (Multiplex MGMS) was designed with primers and probes specific for each pathogen and developed to be carried out in a single tube reaction. Vaccines, MG and MS isolates and DNA from other Mycoplasma species were used for the development and validation of the method. Further, 78 pooled clinical samples...

Mol. Biol. Alves,Camila Fernanda da Silveira; Grott,Camila Schultz; Lunge,Vagner Ricardo; Béria,Jorge Umberto; Tietzmann,Daniela Cardoso; Stein,Airton Tetelbom; Simon,Daniel. Abstract Approximately one-third of the individuals infected with human immunodeficiency virus type 1 (HIV-1) are co-infected with hepatitis C virus (HCV). Co-infected patients have an increased risk for developing end-stage liver diseases. Variants upstream of the IFNL3 gene have been associated with spontaneous and treatment-induced clearance of HCV infection. Recently, a novel polymorphism was discovered, denoted IFNL4 ΔG > TT (rs368234815), which seems to be a better predictor of spontaneous clearance than the IFNL4 rs12979860 polymorphism. We aimed to determine the prevalence of the IFNL4 ΔG > TT variants and to evaluate the association with spontaneous clearance of HCV infection in Brazilian HIV-1 patients. The IFNL4 ΔG > TT genotypes were... Tipo: Info:eu-repo/semantics/other Palavras-chave: IFNL4 genotypes; HIV/HCV co-infected patients; Spontaneous clearance.

Wortmann,André Castagna; Simon,Daniel; Mazzoleni,Luiz Edmundo; Sander,Guilherme Becker; Francesconi,Carlos Fernando de Magalhães; Nabinger,Débora Dreher; Grott,Camila Schultz; Rech,Tássia Flores; Mazzoleni,Felipe; Lunge,Vagner Ricardo; Bona,Laura Renata de; Milbradt,Tobias Cancian; Silveira,Themis Reverbel da. Abstract Functional dyspepsia and lactose intolerance (adult-type hypolactasia, ATH) are common conditions that may coexist or even be confounded. Their clinical presentation can be similar, however, lactose intolerance does not form part of the diagnostic investigation of functional dyspepsia. Studies on the association between functional dyspepsia and ATH are scarce. This study aimed to evaluate whether ATH is associated with symptoms of functional dyspepsia. Patients fulfilling the Rome III diagnostic criteria for functional dyspepsia underwent genetic testing for ATH. Dyspeptic symptoms were evaluated and scored according to a validated questionnaire. The diagnostic criteria for ATH was a CC genotype for the -13910C/T polymorphism, located upstream of...
