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...
Isolation, pathogenicity and disinfection of Staphylococcus aureus carried by i...
Oliveira,Pollianna S.; Souza,Simone G.; Campos,Guilherme B.; Silva,Danilo C.C. da; Sousa,Daniel S.; Araújo,Suerda P.F.; Ferreira,Laiziane P.Currently, hospital infection is a serious public health problem, and several factors may influence the occurrence of these infections, including the presence of insects, which are carriers of multidrug-resistant bacterial species. The aim of this study was to isolate staphylococci carried by insects in two public hospitals of Vitoria da Conquista, Bahia and to identify the resistance profile, pathogenicity and...
