Lactobacillus are an industrially important group of probiotic organisms that
play an important role in human health by inhibiting harmful and pathogenic bacteria
growth, boosting immune function, and increasing resistance to infection. This study
aimed to isolate and identify Lactobacillus isolates from apparently healthy cow milk.
Lactobacillus isolates were obtained from 10/250 (4%) samples. Lactobacillus isolates
were identified according to phenotypic characterization and genotypic methods
including (16S rRNA gene sequences). According to the 16S rRNA gene sequencing
of the isolated bacteria they were belonged to the three species Lactobacillus
acidophilus as (50%), Lactobacillus amylovorus (30%), and Lactobacillus crispatus
(20%). All of the isolates were well identified by of molecular techniques. The current
results revealed the presence of different species of Lactobacillus in the cow milks
which is considered an important source of probiotics
