Abstract Campylobacter fetus is a venereal pathogen of cattle and sheep, an opportunistic human pathogen. It often assumed that C. infection occurs in humans as zoonosis through food chain transmission. Here we show mammalian consists distinct evolutionary lineages, primarily associated with either or bovine hosts. We use whole-genome phylogenetics on 182 strains from 17 countries to provide evidence may have originated around 10,500 years ago “jumped” into during the livestock domestication...
O objetivo do presente trabalho foi investigar o potencial antimicrobiano oleorresina de Copaifera reticulata Ducke em isolados Staphylococcus coagulase positiva (SCP) provenientes casos otite externa cães. método microdiluição caldo utilizado para determinação da concentração inibitória mínima (CIM) e bactericida (CBM) copaíba. Em adição, determinado perfil suscetibilidade aos antimicrobianos dos SCP pelo difusão ágar. Oito classes foram usadas cálculo multirresistência antimicrobiana. A...
ABSTRACT: Bovine genital campylobacteriosis (BGC) is a venereal disease caused by Campylobacter fetus subsp. venerealis. In countries with large cattle herds, such as Brazil, where the use of natural breeding reproductive strategy common practice, BGC considered an important cause failure and economic losses. these cases, bull asymptomatic carrier bacterium infected females can have infertility even abortions. The techniques for diagnosis C. are isolation in culture medium identification...
Introduction: The majority of abortions in mares are associated with placental infections caused by opportunistic bacteria. Rhodococcus equi is widespread the environment stud farms and Klebsiella oxytoca found on mucosal surfaces horses. Both can occasionally cause infection abortion mares. To best our knowledge, however, there have been no reports R. K. coinfection experiencing placentitis abortion. present report describes an uncommon case a thoroughbred mare Brazil, which virulence...
1. This study determined the antimicrobial resistance profile and biofilm-forming ability of Salmonella enterica strains isolated from commercial broiler houses over a three-year period in southern Brazil.2. Of 720 drag swabs analysed, 37 (5%) tested positive for non-typhoidal spp. S. Heidelberg was most frequent serovar.3. Among resistant (83.8%; 31/37), common to tetracycline, ampicillin nalidixic acid. Multidrug found 65% (24/37) isolates, with large proportion multidrug (81%; 13/16).4....
A ceratoconjuntivite infecciosa (CI), embora raramente fatal, resulta em perdas econômicas significativas para os rebanhos bovinos e ovinos. Os principais agentes causadores dessa enfermidade são Moraxella bovis ovis. Em 2007 foi descrita uma nova espécie também responsável pela CI denominada bovoculi, que até o presente momento, não havia sido relatada no Brasil. Assim, objetivou-se com este trabalho caracterizar distinguir 54 isolados de spp. amostras clínicas oriundas 34 17 ovinos,...
Data about phylogenetic classification of Escherichia coli colonizing calves, lambs and foals are routinely neglected restricted to outdated methodologies, even in the context antimicrobial susceptibility (AS) testing. Thus, aim this study was determine diversity AS profile E. colony-forming units (CFUs) from faecal samples healthy animals. Five CFUs were randomly selected each culture calves (n = 13), 13) totalizing 195 phylo-typed by quadruplex PCR. The five 15 (five animal species; n 75...
Introduction: Mycobacterium goodii is a rapidly growing non‐tuberculous mycobacterium that has recently been associated with severe infections in animals and humans. The ecological niche of M. remains unclear, cases large remain either undiagnosed or misdiagnosed. Case presentation: We present case 5‐year‐old Holstein cow showing mastitis signs pronounced glandular hardening did not respond to antibiotic therapy. During the milk bacteriological culture, we observed Gram‐positive acid‐fast...
ABSTRACT: Blackleg, an acute myonecrosis caused by Clostridium chauvoei, is usually underdiagnosed since the rapid transport of adequate samples for laboratory testing difficult. This study tested a direct polymerase chain reaction (PCR) technique using common filter paper impregnated with cattle tissue obtained from animals suspected blackleg. Twenty-five samples, belonging to eleven Rio Grande do Sul State, Brazil, were analyzed. The PCR identified eight positive corroborating results...
Blackleg is an acute and frequently fatal infection that mainly affects cattle caused by Clostridium chauvoei. Formalin-killed, whole-cell vaccines are commonly used to control blackleg. The aim of this study was verify the protective efficacy two commercial against guinea pigs with strains C. chauvoei, a virulent field strain (SBP 07/09) reference in official tests (Manguinhos-Teixeira or MT). challenge were characterized whole genome sequencing, minimal inhibitory concentrations 15...
In this study 30 lactating sheep were used to evaluate the oxidative profile and leucocytes of animals with chronic mastitis.Groups, containing 15 each, divided into: group positive presenting clinical signs mastitis, control which did not present alterations in mammal gland or milk.Milk samples collected California Mastitis Test (CMT) microbiologic examination performed.In addition, total leukocytes, antioxidant capacity (TAC), oxidant status (TOS) nitric oxide measured through blood...
