Salmonella is one of the major causative agents foodborne infections. Salmonellosis becomes more dangerous when strains resistant to several antibiotics are found in food, especially chicken, primary transmission vehicles this pathogen for humans. The present study aimed estimate occurrence chicken carcasses from state Mato Grosso, Brazil, as well determine antibiotic resistance profile and genotypic characteristic multi-drug (MDR) isolates. During a 15-month period, 01/2014 05/2015, 850...
Abstract The emergence and reemergence of mosquito-borne diseases in Brazil such as yellow fever, zika, chikungunya, dengue have had serious impacts on public health. Concerns been raised due to the rapid dissemination chikungunya virus across country since its first detection 2014 Northeast Brazil. In this work, we carried out on-site training activities genomic surveillance partnership with National Network Public Health Laboratories that led generation 422 genomes from 12 Brazilian states...
Fish is a nutritionally rich product; however, it easily contaminated by pathogenic microorganisms, such as Salmonella spp. Therefore, this study aimed to identify the best concentration of sodium hypochlorite (NaClO), exposure time, and water temperature that allow most effective antimicrobial effect on viable population Thus, Enteritidis ATCC 13076 Schwarzengrund were exposed different time frames, ranging from 5 min 38.5 min, temperatures between °C, NaClO concentrations 0.36 6.36 ppm,...
Salmonella spp. is not part of the fish microbiota, being introduced through contaminated water or improper handling. In slaughterhouses, five parts per million (ppm) free chlorine recommended in washing step to eliminate this pathogen. However, still detected processing plants due persistent contamination as a result chlorine–organic matter interactions that reduce effectiveness. Therefore, study aimed test whether organic contained culture media and washes interferes with efficacy at 2 5...
A contaminação de alimentos tem aumentado a cada ano, e atualmente representa um risco potencial para saúde humana. Staphylococcus spp. foi isolado processados in natura identificados através dos teste Gram, catalase, coagulase, DNAase, termonuclease, acetoína (VP) metabolismo carboidratos (glicose, maltose manitol). Foram selecionadas cepas com evidente reação realizada análise enterotoxinas estafilocócicas, por imunoenzimático (VIDAS - Staph Enterotoxin bioMerieux). Reação positiva...
Os alimentos são passíveis de contaminação por diferentes agentes etiológicos, podendo levar a doenças manifestadas ação microorganismos patogênicos ou suas toxinas. Pesquisou-se ocorrência cepas Staphylococcus, assim como sua capacidade para produção enterotoxinas em leite produzido e/ou comercializado no Estado Pernambuco, Brasil. Foram isoladas e selecionadas 109 Staphylococcus coagulase positiva negativa in natura. A identificação das foi realizada meio testes morfológicos bioquímicos,...
Salmonella is one of the major causative agents foodborne infections. In this study, 225 samples different types cheeses produced by Brazilian dairy industry were analysed. Samples submitted to a spp. investigation using conventional microbiology, multiplex polymerase chain reaction (multiplex PCR) and disc‐diffusion method. The occurrence was 1.33% (3/225); two strains ( S . Infantis Schwarzengrund) detected in Prato cheese, strain S. Anatum) Mozzarella cheese. three showed resistance...
Shiga toxin-producing Escherichia coli (STEC) is a group of emerging pathogens that can cause human diseases, including hemolytic uremic syndrome (HUS) and hemorrhagic colitis (HC). Monitoring slaughtering stages checking contamination points are crucial for the production safe food. In this context, aim study was to verify by STEC strains, determine evaluate resistance profile 12 antimicrobials used in both veterinary medicine. A total 80 samples were obtained from eight collection (pen...
Fat replacement by carboxymethyl cellulose (CMC) and inulin (IN) for the manufacture of low-fat lamb patties was investigated utilizing mixture design. The effect fat, CMC, IN levels on texture, color, weight loss, patty diameter reduction, sensory characteristics investigated. presence CMC decreased hardness (p < 0.05). While also springiness, cohesiveness, gumminess, chewiness 0.05), no adhesiveness observed > increased L* (lightness), a* (redness), b* (yellowness) values in raw patties,...
The Brazilian state of Mato Grosso is the largest producer and exporter beef in country, but few studies relevance have been conducted to evaluate microbiological safety its products. This study aimed estimate prevalence Listeria monocytogenes (LM) export-approved from characterize isolates terms molecular properties antimicrobial resistance. From a total 50 samples analyzed, sp. was isolated 18 (36% prevalence). confirmed 6 (12% Among serotype groups assessed by multiplex PCR, 4 (4b, 4d or...
Salmonella and Escherichia coli are the main bacterial species involved in food outbreaks worldwide. Recent reports showed that chemical sanitizers commonly used to control these pathogens could induce antibiotic resistance. Therefore, this study aimed describe efficiency of organic acids when inactivating wild clinical strains E. coli, targeting a 4-log reduction. To achieve goal, three methods were applied. (i) Disk-diffusion challenge for acids. (ii) Determination MIC two (acetic lactic),...
This study aimed to evaluate the occurrence of parasitic organisms in crisp lettuce sold supermarkets Cuiabá, MT. Forty five samples randomly collected triplicate from three large supermarket chains (9 company A, 27 B and 9 C), which were different suppliers called: F1, 2, 3, 4 5 analyzed. Samples analyzed by two techniques for detection organisms: spontaneous sedimentation simple centrifugation. 66.7% samples(30/45) showed contamination, comprising 182 types parasite, there 67 Ascaris sp.,...
Neste trabalho foram avaliadas as qualidades microbiológica, física e química de polpas frutas congeladas diferentes sabores marcas, comercializadas no município Cuiabá – MT. O experimento foi conduzido em DIC, disposto um arranjo fatorial 3 x 2, amostras três marcas (X, Y Z) dois períodos coletas (junho/2014 outubro/2014), triplicata. Foram realizadas análises de: coliformes a 35 oC 45 oC, Salmonella spp., fungos filamentosos leveduras, cor (L*a*b*), pH, acidez titulável, sólidos solúveis,...
Enterobacteriaceae, coliforms, and Escherichia coli counts are important hygiene indicators may be pathogenic. Thus, the aim of present study was to determine microbiological contamination in head meat, esophagus, diaphragm, boning scraps evaluate hygienic conditions processing these products. The Petrifilm® (3M) method for determining total E. applied 104 samples. APHA, European Union, PAHO/WHO, Brazil/MAPA recommendations were followed. Bleeding skinning knives contaminated with (61.5%)....
Characterize Escherichia coli and E. -producing (STEC) isolates from Brazilian beef to determine heat resistance the presence of transmissible locus stress tolerance (tLST).Twenty-two STEC previously isolated characterized as by PCR were subjected different survival challenges (60°C 71°C). Furthermore, three tLST-positive one tLST-negative isolate selected for WGS analysis. Phenotypic results indicated that 3/22 (13.64%) resistant, 12/22 (54.54%) moderately 7/22 (31.82%) sensitive...

ABSTRACT: In this study, the kinetic parameters of mesophilic, psychrotrophic and lactic acid bacteria in vacuum-packed beef at 1 °C 4 were estimated from experimental growth curves produced by samples stored during 21 60 days, respectively. a separate experiment, survival multidrug resistant (MDR) Salmonella enterica O:4,5 1°C was also characterized. The shelf-life 16.1 days (95% CI: 14.8 - 17.3 days), whereas it longer than because mesophiles count towards end experiment 12.5 ln CFU.g-1...
