Lactobacillus Genus Identification Isolated from Gastrointestinal Tract of Chickens after Bee Products Application Using FISH and RTQ PCR Methods.

The general objective of this study was to examine the effect of bee products on the lactobacilli colonization of chickens. Bee products were administered to both feed mixtures in various amounts in addition to the control group. First experimental group was with propolis in feed mixture with the addition of 400 mg propolis per 1 kg of compound and second group was with pollen in feed mixture with the addition of 450 mg pollen per 1 kg of compound. In this experiment, quantitative counts of lactobacilli in ceca of 49-day-old chicken (Ross 308) using classical and fluorescence in situ hybridization (FISH) method were investigated. Counts of lactobacilli on Man, Rogosa and Sharpe (MRS) agar were monitored. To check the reliability of traditional methods of cultivation samples were evaluated by fluorescence in situ hybridization (FISH). Lactobacillus cells, isolated from gastrointestinal tract, were detected after hybridization of fluorescently labeled probe with bacterial cells. Counts of colony forming units (CFU) of lactobacilli were compared in experimental and control treatments, respectively. The lowest count was detected in the control experimental group. The highest count was detected in the third experimental group where was 450 mg of pollen added to 1 kg of feed mixture. Using Real-time polymerase chain method (PCR), we identified the species range of the genera Lactobacillus in the intestinal tract of broiler. Detected species from the genus Lactobacillus were L. crispatus, L. salivarius and L. acidophilus. [ABSTRACT FROM AUTHOR]
