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
