The present study was carried out to evaluate the occurrence of Salmonellae in raw broiler parts and determine antimicrobial resistance profile isolated strains. Twenty-four (39.3%) samples were positive for Salmonella twenty-five strains isolated, since two different serovars detected one single sample. Enteritidis most prevalent serovar. Among isolates, 95.2% belonged Phage Type 4 (PT4) (20/21) 4.8% PT7 (1/21). Twenty-two (88%) resistant at least agent, generating eight patterns. S....
Este estudo foi realizado com o objetivo de determinar a prevalência Salmonella sp em suínos abatidos frigoríficos sob inspeção federal no Rio Grande do Sul. Amostras fezes e linfonodos foram coletadas três diferentes Estado. A partir da análise microbiológica das amostras 300 animais, encontrou-se uma 55,66%, 17,6% isolamentos dos linfonodos, 18,3% 19,6% ambos os materiais. Foram identificados 26 sorovares 226 isolados sp. Os mais prevalentes foram: Typhimurium (24,3%), Agona (19,9%), Derby...
A kombucha é uma bebida fermentada por cultura simbiótica de bactérias e leveduras microbiologicamente ativas (SCOBY) com propriedades apontadas como benéficas à saúde. Foi realizado estudo descritivo kombuchas produzidas em escala Porto Alegre/RS, sendo coletados amostras para o isolamento microrganismos presentes na kombucha, bem nos insumos utilizados (SCOBY chá verde). As bebidas foram analisadas nas versões original saborizada sem homogeneização, triplicata, perfazendo um total 12...
The present study aimed at evaluating the effect of prebiotic Bio Mos™ (2 kg/ton up to 10 days; 1 from 21 and 0.5 days slaughter), probiotic Lac XCL 5x™ (by spray-mixing), a combination two supplements (prebiotic + probiotic), one growth promoter antimicrobial agent (Avilamycin 15 ppm). Birds were orally challenged with inoculated Salmonella Enteritidis (SE) 10(6) CFU 3 age. Four hundred eighty male Ross chicks used. experiment lasted 28 days, analyses conducted Cecum liver bacterial...
Stenotrophomonas maltophilia is an emerging nosocomial pathogen responsible for several infections in immunocompromised patients. To characterize the antimicrobial resistance and virulence potential of this microorganism a Brazilian hospital, total 936 samples were collected from environment medical devices, 100 isolates clinical specimens obtained same hospital. S. was found 3% collected, especially bed rails hospital rooms. The smf-1 gene detected 23% 42% isolates, respectively, almost all...
In order to study the epidemiology of Salmonella Enteritidis outbreaks and determine source contamination so that a recurrence can be avoided, detailed characterization is necessary. Thus, purpose this was verify whether rep-PCR able discriminate among isolates. Phage typing, detection virulence genes antimicrobial resistance testing were also associated results. One hundred two S. isolates from broiler carcasses, food, human, pigs, poultry-related samples, nine other countries genotypically...
Estudou-se a prevalência de Salmonella spp. em suínos ao abate e compararam-se os resultados obtidos no isolamento na sorologia modo determinar fase mais importante infecção (granja ou transporte/espera pré-abate) relação número portadores encontrados abate. Foram avaliados 40 rebanhos três diferentes empresas do sul Brasil, com colheitas sangue linfonodos mesentéricos 20 animais por lote. O soro foi submetido ELISA produzido antígeno somático Typhimurium. A frequência variou 62,5% 85,0%,...
Noventa e três amostras de embutidos coletados no Mercado Público Central Porto Alegre foram analisadas quanto à presença Salmonella sp. contagem coliformes fecais. Todos as apresentaram ausência sp., enquanto, em relação aos fecais, constatou-se que quatorze frescais encontravam-se acima do padrão estabelecido pela portaria n° 451, vigor momento da coleta. Entretanto, se fossem considerados os parâmetros estabelecidos na Resolução 12, atualmente, apenas cinco seriam consideradas fora...
Na prevenção da ocorrência ou na interrupção evolução de enfermidades infecto-transmissíveis comuns aos animais e seres humanos, como é o caso salmonelose, uso um desinfetante capaz agir sobre agente causal quando em vida livre, no ambiente, exerce grande importância. No entanto, a resistência microbiana, intrínseca adquirida, pode apresentar-se limitante deste instrumento sanitário. Objetivando monitorar sensibilidade Salmonella Typhimurium, 96 amostras isoladas suínos abatidos Estado do...
O objetivo do presente estudo foi acompanhar a produção de queijo frescal leite cabra, avaliando qualidade higiênica processamento pela quantificação coliformes, S. aureus e mesófilos totais. A três diferentes lotes acompanhada, sendo coletadas amostras várias etapas processamento. Além disso, pertencente ao lote acompanhado foram na prateleira um estabelecimento comercial durante seu período validade. Os suabes coletados semeados em ágar sangue ovino; as água submetidas à Colimetria; demais...
Campylobacter is not routinely tested in foodborne disease investigations Brazil. Here, we studied the occurrence of among other food-related bacteria commonly found outbreaks reported Rio Grande do Sul State, Southern Seventy-two food samples were analyzed by using culture-based detection methods during 18-month investigation 36 outbreaks. The sampled foods from all negative for . However, at least one investigated foodborne-related was detected 29.17% (21/72) samples. Taken together, these...
Healthcare-associated infections (HAIs) represent a global challenge and an even more staggering concern when related to microorganisms capable of resisting surviving for long periods in the environment, such as Acinetobacter spp. Strategies that allow reduction pathogens from hospital environments additional barrier infection control protocols, minimizing transmission hospitalized patients. Considering antimicrobial properties copper, here, bacterial load presence were monitored on high...
The objective of this study was to assess the level and type antibiotic resistance in Salmonella stra ins isolated from swine slaughtered Rio Grande do Sul, Brazil. agar diffusion method used test 226 samples against 14 antimicrobial drugs. highest were found sulfonamide 83.2%), tetracycline (42.9%), sulfamethoxazole/trimethoprim ( 18.6%), ampicillin (18. 1 %). Strains serovars Typhimurium Agona most resistant. Serovar particular showed a significantly greater number multi-resistant (against...
In southern Brazil the isolation of Salmonella from pigs and pork has been previously reported. The aim this study was to compare results seroprevalence intestinal contents slaughtered pigs, identify probable contamination source for these herds. Blood 58 herds (15 pigs/herd) were sampled. Three fecal samples originating same herd pooled, resulting in five pools/herd. Fecal pools submitted an protocol as described.
A collection of porcine S. typhimurium strains isolated in the state Rio Grande do Sul, Brazil during 1999/2001 was submitted to phage typing, antimicobial susceptibility test and rep-PCR.
