The objective of this study was to determine the effect of colostrum on microbial populations of yogurt and kefir. For this purpose, raw bovine colostrum is freeze-dried and added to yogurt and kefir on 8% and 16% (w/w; colostrum/product) dilutions. The results showed that, effect of colostrum on total mesophilic aerobic bacteria counts of yogurt and kefir are negligible. Streptococcus thermoph...

Ventilator-associated pneumonia (VAP) is a common nosocomial infection in mechanically ventilated patients. Biofilm formation is one of the mechanisms through which the endotracheal tube (ET) facilitates bacterial contamination of the lower airways. In the present study, we analyzed the composition of the ET biofilm flora by means of culture dependent and culture independent (16 S rRNA gene clo...

Heat-stable antibacterial activity in the following suspensions was demonstrated against Pseudomonas aeruginosa at pH 6.5, 6.0, and 5.5: (i) pooled colon contents of normal mice; (ii) an anaerobic, 48-h culture of normal mouse feces; and (iii) anaerobic, 48-h cultures of different bacteria from human colon flora (Escherichia coli, Bacteroides fragilis, Klebsiella pneumoniae, and Proteus mirabil...

The role that the vaginal flora plays in protecting the host from sexually transmitted infections (STIs), including HIV infection, is becoming increasingly appreciated. Significant alterations in the microbiological environment of the vag-inal ecosystem, such as those that occur in bacterial vaginosis (BV), appear to be a biological risk factor for the acquisition and transmission of STIs/HIV, ...

This study was carried out to determine the microorganism population affecting silage quality of sweet sorghum and mung bean cultivated with different sowing patterns as mixture or sole crop. Twin row (20×55 cm spacing), narrow (55 spacing) conventional (75 were used patterns. The mixtures formed based on plant densities alternative numbers bean. Sowing made alternation rows 1 plus (R1:1) 2 (R1...

Manipulation of the human gut microflora is being attempted as a means of introducing into the digestive tract new micro-organisms which are beneficial to the host or which are able to bring about advantageous changes to the equilibrium populations and metabolic activities of the indigenous flora. In theory, this can be achieved by ingestion of nutrients or growth substances specifically favour...

This study investigated the rate of potentially pathogenic bacteria in fresh soft cheeses made on small dairy farms in Serbia. This type of cheese is made on individual farms from cow, sheep and goat milk. White fresh cheeses from mountain villages of Serbia are economically important for these areas. The purpose of this study was to investigate the micro flora of white cheeses with special emp...

s: Probiotic mean live microorganisms that have beneficial effects on their host’s health. Although probiotic strains can be isolated from many sources; for human applications the main criteria is being human origin. Breast milk is an important nutrient source for neonates. Lots of studies showed that this fluid has beneficial effects on the health of neonates. One reason of being beneficial is...

Lactobacilli have long been considered to be protective flora in the vagina. In this study, samples were taken from the lateral vaginal wall of 19 healthy women, and 58 strains of Lactobacillus spp. were isolated from 10 of these women. The identification results revealed that Lactobacillus gasseri was the predominant lactobacilli in healthy women. The amounts of lactic acid and hydrogen peroxi...

The isolated and identified bacteria from yoghurt sample are of spp. Lactobacillus. The bacteria of this spp. are lactic acid producers. These spp. resembles to Lactobacillus acidophilus. A probiotic is a microorganism known to be friendly and beneficial to its host when consumed. In today's time, probiotics are a very popular subject of research among scientists and pharmaceutical companies .D...
