Widespread Pig Farming Practice Linked to Shifts in Skin Microbiomes and Disease in Pond-Breeding Amphibians.

Farming practices may reshape the structure of watersheds, water quality, and the health of aquatic organisms. Nutrient enrichment from agricultural pollution increases disease pressure in many host-pathogen systems, but the mechanisms underlying this pattern are not always resolved. For example, nutrient enrichment should strongly influence pools of aquatic environmental bacteria, which has the potential to alter microbiome composition of aquatic animals and their vulnerability to disease.

Biosurfactant Produced by Salmonella Enteritidis SE86 Can Increase Adherence and Resistance to Sanitizers on Lettuce Leaves (Lactuca sativa L., cichoraceae).

Salmonella Enteritidis SE86 is an important foodborne pathogen in Southern Brazil and it is able to produce a biosurfactant. However, the importance of this compound for the microorganism is still unknown. This study aimed to investigate the influence of the biosurfactant produced by S.

Antagonistic activity of Lactobacillus acidophilus LA10 against Salmonella enterica serovar Enteritidis SE86 in mice.

Salmonella enterica serovar Enteritidis is one of the main pathogens responsible for foodborne illness in Brazil. Probiotic bacteria can play a role in defense and recovery from enteropathogenic infections. In this study, the ability of Lactobacillus acidophilus LA10 to colonise and exert antagonistic effects in the gastrointestinal tract was tested before and during experimental infection in conventional mice contaminated with S.

Survival and transfer of microorganisms from kitchen sponges to surfaces of stainless steel and polyethylene.

Introduction: Contaminated sponges might lead to cross-contamination in kitchens since they can transfer microorganisms to surfaces where microorganisms can survive for hours or days and contaminate food. The main objective of this study was to evaluate the transfer and the survival of bacteria from kitchen sponges to surfaces of AISI 316 stainless steel and polyethylene.

Methodology: Twenty-four sponges were collected from industrial kitchens in the state of Rio Grande do Sul and aseptically split into two equal parts.

[Microbiological monitoring of underground waters in cities of the Extreme West of Santa Catarina State].

The degradation of natural resources is increasing in alarming numbers, especially water sources that is constant changes in its quality. Because of this, more and more people come using groundwater for human consumption, but the big problem is contamination by these pathogenic microorganisms. The purpose of this study was to evaluate the microbiological quality of groundwater districts in the Extreme West of Santa Catarina, Brazil.
