Serosurvey of anti-treponema pallidum (syphilis), antihepatitis C virus and ant...
Felipetto,Laís Giuliani; Teider-Junior,Pedro Irineu; Silva,Felipe Fortino Verdan da; Couto,Anahi Chechia do; Kmetiuk,Louise BachABSTRACT Homeless persons have been considered as one of the most susceptible populations to sexually transmitted infections. In Brazil, these population experienced an increase of 140% from 2012 to 2020. Accordingly, the present study aimed to assess the seroprevalence of anti-Treponema pallidum, anti-HCV, anti-HIV antibodies, and the risk factors associated with homeless persons in a daytime attendance shelte...
Ovarian hormones influence immune response to Staphylococcus aureus infection
Souza,Clarissa Leal Silva e; Oliveira,Hellen Braga Martins; Santos Júnior,Manoel N.; Silva,Mariângela de Oliveira; Coqueiro,Igor LopesABSTRACT Objective: Staphylococcus aureus infections remain associated with considerable morbidity and mortality in both hospitals and the community. There is little information regarding the role of ovarian hormones in infections caused by S. aureus. The aim of this study was to evaluate the effects of ovariectomy in the immune response induced by S. aureus. Methods: Female mice BALB/c were ovariectomized (OVX...
Microbiological and molecular detection of Mycoplasma bovis in milk samples fro...
Salina,Anelise; Timenetsky,Jorge; Barbosa,Maysa S.; Azevedo,Cristiane M.; Langoni,HelioABSTRACT: The genus Mycoplasma includes more than 200 bacterial species that cause disease in animals. It is responsible for causing mastitis in bovines and may be related to other manifestations, such as arthritis and pneumonia in calves and heifers. The present study aimed to detect Mycoplasma bovis isolated from milk samples of bovine clinical mastitis, and to compare the isolation rates in two culture media...
Bacteria isolated from the lower respiratory tract of sheep and their relations...
Franco,Mariane F.; Gaeta,Natália C.; Alemán,Mario A.R.; Mellville,Priscilla A.; Timenetsky,Jorge; Balaro,Mário F.A.; Gregory,LilianABSTRACT: 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, tracheobronchial flushing samples were obtained. The usual bacteria and Mycoplasma spp. were searched,...
Bacterial pathogens of the lower respiratory tract of calves from Brazilian rur...
Gaeta,Natália C.; Ribeiro,Bruno L.M.; Alemán,Mario A.R.; Yoshihara,Eidi; Nassar,Alessandra F.C.; Marques,Lucas M.; Timenetsky,Jorge; Gregory,LilianABSTRACT: Bovine respiratory disease (BRD) is considered the major cause of economic losses in dairy and beef cattle production. The study aimed to detect the most important bacteria related to respiratory disease in tracheobronchial fluid samples of healthy and dairy calves with clinical signs of BRD in Brazilian rural settlements. Hundred and forty-one mongrel dairy calves were randomly selected from 42 famil...
Molecular characterization of ureaplasmas isolated from reproductive tract of g...
Oliveira,Rosângela C.; Yamaguti,Maurício; Marques,Lucas M.; Buzinhani,Melissa; Rizzo,Huber; Meira-Junior,Enoch Brandão de Souza; Guimarães,Ana Márcia S.Abstract Ovine/caprine ureaplasmas have not yet been assigned a species designation, but they have been classified into nine serotypes. Herein ureaplasmas were searched for in 120 samples of vulvo vaginal mucous from sheep and 98 samples from goats at 17 farms. In addition, semen samples were collected from 11 sheep and 23 goats. The recovered ureaplasma were from sheep and goats from animals without any reprod...
Intra-uterine experimental infection by Ureaplasma diversum induces TNF-α media...
Silva,Jamile R.; Ferreira,Lício F.A.A.; Oliveira,Percíllia V.S.; Nunes,Ivanéia V.; Pereira,Ítalo S.; Timenetsky,Jorge; Marques,Lucas M.Ureaplasma diversum is an opportunistic pathogen associated with uterine inflammation, impaired embryo implantation, infertility, abortions, premature birth of calves and neonatal pneumonia in cattle. It has been suggested that the intra-uterine infection by Ureaplasma diversum can cause vascular changes that hinder the success of pregnancy. Thus, the aim of this study was to evaluate the changes of intrauterin...
Evaluation of a PCR multiplex for detection and differentiation of Mycoplasma s...
Mettifogo,Elena; Buzinhani,Melissa; Buim,Marcos R.; Timenetsky,Jorge; Ferreira,Antonio J. PiantinoMycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) are the mycoplasma infections of most concern for commercial poultry industry. MG infection is commonly designated as chronic respiratory disease (CRD) of chickens and infections sinusitis of turkeys. MS causes sub clinical upper respiratory infection and tenosynovitis or bursitis in chickens and turkeys. The multiplex PCR was standardized to detect sim...
Quality Control of Biotechnological Inputs DetectingMycoplasma
Netto,Cristiane; Soccol,Vanete Thomaz; Sepulveda,Lya; Garcia,Gabriel Henrique Oliveira; Timenetsky,JorgeThe aim of this work was to study the Polymerase Chain Reaction (PCR) as a tool of quality control of bovine sera and cellular cultures used in the biotechnological industry. A total of 46 samples of bovine sera derived from two slaughterhouses and 33 samples of BHK21 cells derived from two biotechnological industries were evaluated using the primers GPO-3 (sense) and MGSO (antisense). The PCR technique sensibi...
Experimental infection of BHK21 and Vero cell lines with different Mycoplasma spp.
Netto,Cristiane; Soccol,Vanete Thomaz; Sepulveda,Lya Madureira; Timenetsky,JorgeMycoplasma spp, belongs to the class Mollicutes and is capable to produce alterations in cellular cultures causing damages to the biotechnological industry. Bioproducts generally require two essential inputs, bovine serum and cells. The study herein aims to evaluate the mycoplasma concentrations that affect the growing of BHK21 and Vero cells. The species used were: Mycoplasma orale, M. salivarium, M. arginini ...
