Abstract:

Currently nosocomial infections caused by Serratia marcescens and Enterobacter cloacae have been increasing for this reason its clinical interest has increased as well. Moreover Salmonella spp. is considered major pathogenic bacteria due to multiple outbreaks of food poisoning which is caused, as well as gastrointestinal infections. The aforementioned strains are within the family Enterobacteriaceae, this group of microorganisms are characterized by their ubiquity, and are found in soil, water and in the large intestine of some insects and animals, including man. In addition to its ubiquity these organisms are resistant to multiple drugs, hence the severity of the problem, therefore it is necessary to search for new alternatives for treatment and control such as the use of probiotics as numerous studies show the importance of lactic acid bacteria (LAB), considered as probiotics in the treatment and prevention of digestive disorders in man. Conditioned medium freeze dried Bifidobacterium longum and Lactobacillus casei was added on culture of Serratia marcescens, Enterobacter cloacae and Salmonella spp. Determination was made by determination of colony forming units per ml. High antibacterial activity was observed. These findings add to the various investigations with probiotics aimed at treating gastrointestinal infections.
