This study evaluated the capacity of Listeria monocytogenes and Salmonella Typhimurium to form pure mixed biofilms on polypropylene surface analyzed expression genes related biofilm formation within 24 h 120 h. The planktonic sessile growth L. S. were incubation temperature. There was no statistical difference between total population not only in biofilms, but also at 12 °C 37 °C. Pure able maintain viable cells for 3000 10 with counts greater than when incubated h, a increase biofilms....
The aim of this study was to investigate the presence adenovirus (AdV), rotavirus (RV), and hepatitis E virus (HEV) in beef, pork, chicken meat cuts retail trade city Uruguaiana, RS, Brazil. A total 131 products were collected (beef, n = 55; chicken, 47; 29) from 18 commercial establishments (supermarkets, 7; butchers, markets/grocery stores, 4). All samples evaluated for AdV, RV, HEV. genomes RV AdV identified 29% (n 38) 5.34% 7) samples, respectively. HEV not any samples. Chicken had a...
This study aimed to evaluate the antimicrobial and antibiofilm activities of black pepper essential oil (BPEO) piperine effect on gene expression in a multispecies biofilm composed Listeria monocytogenes, Salmonella Typhimurium, Pseudomonas aeruginosa polypropylene surface. The minimal inhibitory concentrations BPEO were 100 25 mg/mL, respectively, against this consortium microorganisms. Sessile cell counts 5.35–7.35 log CFU/cm2 varied over time. total population eradicated ranged from 78.9%...
Annual ryegrass (Lolium multiflorum Lam.) is widely used for feeding ruminants, and the conservation of this material as haylage can be an alternative to farms. The aim work study nutritional microbiological value annual (L. pre-dried stored with different dry matter contents (250, 350, 450, 550, 650 750 g kg-1) in anaerobic environment. experimental design was completely randomized six treatments four replications. pH presented at time opening silos showed a linear increase 0.003 units each...
The swine production chain can be a reservoir of antimicrobial-resistant
This study aimed to evaluate the effectiveness of a water spray system in cleaning conveyor belts contaminated with Salmonella and Listeria monocytogenes. Samples were obtained from modular smooth four slaughterhouses Brazil, bacterial presence was assessed sprayed unsprayed belts. From each belt, 400 cm2 sampled using sponges at various time periods (T0: 5:00 h; T1: 9:00 T2: 17:00 h, T3: 22:00 h), these samples submitted for L. monocytogenes detection. The results expressed as frequencies...
The spring forage emptiness is an obstacle to the development of Brazilian livestock, including in Bioma Pampa region. Feed strategies for this period contributed livestock and conservation biome. objective work was know nutritional potential forages during use as planning. experiment had a completely randomized design, with ten four replicates. chemical composition, vitro dry matter digestibility (IVDMD) total digestible nutrient content (NTD) elephant grass, brachiaria cultivars Convert...
This study aimed to evaluate the preoperational cleaning process of a poultry slaughterhouse regarding microbial ecology, microorganisms indicators hygienic-sanitary conditions, Listeria monocytogenes and Salmonella spp. Three hundred twenty samples were collected from surfaces meat cut conveyor belts before (n = 160) after count mesophilic aerobes, Enterobacteriaceae, Pseudomonas spp., in addition detection L. identification ecology by sequencing 16S rRNA gene. The hygiene reduced counts...
ABSTRACT: This study evaluated the sanitary hygienic quality and presence of pathogenic microorganisms in raw meats fresh sausages marketed city Uruguaiana, Rio Grande do Sul (RS), Brazil. We analyzed 238 samples sausages, beef, pork, chicken from 18 commercial establishments (butchers, supermarkets, groceries). Samples were subjected to enumerate hygiene indicator (mesophilic aerobes enterobacteria) detection Salmonella spp. Listeria monocytogenes. The mean counts mesophilic enterobacteria...
The aim of this study was to measure the chemical composition, microbiological profile, fermentative characteristics and aerobic stability olive bagasse silages in natura added with corn bran, soybean rice bran different times sampling. completely randomized design arrangement plots subdivided 4x3 time, five replications. In were allocated main treatments, subplots sampling allocated. studied by determination dry matter (DM) content, pH ammoniacal nitrogen (NH3-N), determining populations...
Evaluating and characterizing production systems using farm characteristics allows the diagnosis of failing points. This can be used to improve productive zootechnical indices. Little is known about milk in state Rio Grande do Sul, therefore, aim this study was characterize Northwest, Center Western Southwest mesoregions considering infrastructure, handling, quantity composition, nutritional intake cattle. To conduct study, 38 Milk Production Units (MPUs) registered at Municipal Secretaries...
ABSTRACT: Surface contamination by pathogenic and deteriorating microorganisms is a constant concern in the food industry. Therefore, this study we evaluated antimicrobial activity of silver nanoparticles (AgNPs), produced using essential oil Lippia origanoides Kunth ethanolic extract Hymenaea martiana Hayne, against bacteria used milk processing. For this, AgNPs were synthesized their was for minimum inhibitory bactericidal concentrations, time-kill, interference on biofilm, application...
The aim of this study was to investigate the impact Good Manufacturing Practices (GMP) on identification and prevention bacteria that could pose a risk patient meals. used two GMP checklists microbiological sampling bacteria, performed six months apart, assess facility’s ability reduce bacterial counts. results showed hygiene deficiencies in all areas hospital. However, there significant improvement compliance following implementation an action plan (p = 0.0234). Before intervention, 55.55%...
This study aimed to assess hygienic-sanitary indicators and the presence of pathogenic agents in fresh cheeses produced through informal methods. A total 51 samples cheese, which were without sanitary inspection sold informally, analyzed for Listeria monocytogenes, Salmonella spp., Bacillus cereus, coagulase-positive Staphylococcus, Escherichia coli, Pseudomonas Mycobacterium bovis, tuberculosis, Coxiella burnetii using microbiological biomolecular analyses. The results revealed detection...
O controle leiteiro é uma ferramenta de gestão alta relevância dentro da bovinocultura leite, a qual tem por objetivo acompanhar situação produtiva das vacas forma individual e todo o lote, bem como estabelecer melhorias diagnosticar erros. Este manejo permite ainda, obter um melhor resultado produtivo econômico do rebanho. No presente estudo foi realizado acompanhamento produção leiteira no Tambo leite Unipampa, registrando diariamente os resultados posteriormente comparando-as com...
