Antimicrobial resistance is a universal threat and leading to new awareness of antimicrobial use. The colonization tissues by some microorganisms carrying genes may pose risk spreading pathogens. Antimicrobials induce an unstable microbiome that compromises the animal's immunity. Indeed, dysbiosis has been linked many alterations in immune response. Here, we isolated bacterial colonizers from nasal microbiota sows describe phenotypic profile on different health managements. One hundred...
Abstract Background Baculovirus comprise the largest group of insect viruses most studied worldwide, mainly because they efficiently kill agricutural pests. In this study, two recombinant baculoviruses containing ScathL gene from Sarcophaga peregrina (vSynScathL), and Keratinase fungus Aspergillus fumigatus (vSynKerat), were constructed. their insecticidal properties analysed against Spodoptera frugiperda larvae. Results Bioassays third-instar neonate S. larvae with vSynScathL vSynKerat...
Equine farming generates a significant amount of waste, prompting the need for effective management. Composting enhanced by filamentous fungi holds promise this purpose. This study focused on inoculating Aspergillus fumigatus isolates in composting horse bedding made with wood shavings (Pinus elliottii). The experiment lasted 90 days, two treatment groups, control and inoculated, analyzing temperature, pH, electrical conductivity, total organic carbon nitrogen content, cellulose,...
Listeria monocytogenes and Salmonella spp. are considered important foodborne pathogens that commonly associated with foods of animal origin. The aim this study was to perform molecular characterization L. isolated from biofilms cattle poultry slaughterhouses located in the Federal District State Goiás, Brazil. Fourteen isolates one sp. were detected slaughterhouses. No All belonged lineage II, 11 different pulsotypes detected. Pulsed-field gel electrophoresis analysis revealed dissemination...
Pig productivity in Brazil has advanced a lot recent decades. Specialized breeds are more vulnerable to pathogens, which boosted the use of antimicrobials by farmers. The selective pressure generated favors emergence resistant bacteria, compromises effectiveness this treatment and limits therapeutic options. In addition increasing costs mortality rates production system, public awareness issue increased. authorities have imposed restrictive measures control banned their as growth promoters....

Avian cellulitis is an inflammatory process in the subcutaneous tissue, mainly located abdomen and thighs. This problem commonly observed poultry at slaughter it considered one of major causes condemnation carcasses Brazil. The aim this study was to perform microbial isolation lesions avian from a processing plant State Goiás order analyze antimicrobial resistance by antibiogram test detect genes polymerase chain reaction. A total 25 samples were analyzed, which 30 bacterial strains...
Listeria monocytogenes is a foodborne pathogen of global relevance that causes outbreaks and sporadic cases listeriosis, acquired through the consumption contaminated products, including milk or meat products ready-to-eat subjected to intensive handling. The objective present study was classify L. isolated from various food-related sources in Federal District Brazil surrounding areas sequence internalin A (inlA) genes these isolates assess their adhesion invasion capacity using Caco-2 cells....
ABSTRACT: The aim of this study was to identify the conjunctival bacterial flora healthy horses in Brasilia (Distrito Federal, Brazil), and evaluate antimicrobial susceptibility isolated strains. We examined 200 eyes 100 adult without any eye problems, belonging 1st Regiment Cavalry Guard (RCG) Brazilian Army Brasilia. Samples were collected from inferior fornix both eyes. Drug sensitivity test performed with antibiotics gentamicin (10µg), tobramycin chloramphenicol (30µg) ciprofloxacin...
This study aimed to verify the presence of Listeria monocytogenes , Salmonella spp., and Escherichia coli in two Brazilian swine slaughterhouses, as well perform antibiograms, detect virulence antimicrobial resistance genes, evaluate vitro biofilm-forming capability bacterial isolates from these environments. One Typhi isolate 21 E . were detected, while L was not detected. S isolated carcass cooling chamber’s floor, resistant several antimicrobials, including nalidixic acid, cefazolin,...
A síndrome do abscesso pituitário é uma doença neurológica responsável por casos esporádicos e surtos, principalmente em bezerros, ocasionando alto índice de mortalidade. Descreve-se a ocorrência os achados clínicos, laboratoriais anátomo-patológicos três bezerros com no Centro-Oeste Brasil. Os animais tinham 8-11 meses idade sinais clínicos mais marcantes relacionaram-se aos nervosos origem cerebral tronco encefálico evolução clínica 7-20 dias. hematologia revelou leucocitose neutrofilia...
Um total de 127 cepas Escherichia coli foi isolado suínos no Distrito Federal, testado para a presença genes enterotoxinas (STa, LT-I, LT-II, Stx1 e Stx2) resistência antimicrobiana. Das isoladas, oito (6,3%) possuíam enterotoxinas, sendo quatro (3,2%) positivas somente três (2,4%) STa uma (0,8%) positiva LT-I. Nenhuma das isoladas apresentou ou Stx2. Quanto ao perfil antimicrobiano, os antibióticos com maiores porcentagens foram lincomicina (100%), sulfonamidas (74,8%) tetraciclina (70,1%),...
ABSTRACT Hepatitis E is caused by the hepatitis virus (HEV) which currently known to be a zoonotic pathogen transmitted pigs. In Brazil, there no information about circulation of HEV in swine herd Federal District. Therefore, cross-sectional study was performed with sera from 449 domestic pigs, provided Secretary Agriculture Blood samples were collected between June and September 2014. A commercially available ELISA kit used for detection IgG antibodies. High seroprevalence antibodies found,...
This study aimed to isolate Campylobacter jejuni and coli from chilled chicken carcasses marketed in the Federal District Region surrounding areas, as well detect occurrence of antimicrobial resistance genes responsible for same. A total 105 were collected, which 7 (6.67%) positive C. 4 (3.81%) coli. These results obtained using both conventional microbiological isolation method polymerase chain reaction assays. All strains subjected susceptibility testing seven antimicrobials. The...
Objetivou-se determinar a microbiota da placa bacteriana subgengival de cães com doença periodontal (DP) e estabelecer o efeito antibioticoterapia. Avaliaram-se 20 graus variados DP coletaram-se amostras antes após Preconizou-se antibioticoterapia distinta em dois grupos, 10 animais cada: clindamicina (G1) metronidazol + espiramicina (G2). Observou-se crescimento bacteriano na maioria dos correlação entre severidade idade animais. Houve redução significativa no antibiograma demonstrou maior...
