Abstract: This study uses a variety of methods, including culturing, the vitek2 system to confirm Salmonella typhmuruim infection in sheep and calves. The study includes 200 animals (100 sheep and 100 calves) that had diarrhea, some of which had blood, and it collected 200 rectal sample swabs and cultured them on various media, such as (nutrient agar, bismuth agar, brian heart agar, EMB (eosin-methylene blue agar) and using differentiation and selective media for Salmonella as (SS agar) and (XLD) agar, which produces black centers colonies due to (H2S production)on these media. After culturing of the 200 rectal samples, the present study's findings showed that 170 (85%) of the samples had positive growth while 30 (15%) of the samples had no growth. Out of 100 sheep rectal samples, 55(55%) showed colonies of S. Spp. while 15(15%), 5(5%), and 15(15%) showed E. coli, Staphylococcus, and Shigella, respectively, with 10(10%) of the samples showing no bacterial growth. The calf's rectal samples also revealed that 45 (45%) out of 100 samples had colonies of Salmonella spp., while 20 (20%), 5 (5%), and 10 (10%) had colonies of E. coli, Staphylococcus, and Shigella, respectively. Twenty (20%) of the samples showed no bacterial development. The current study's high percentage of diarrheic sheep and calves are as follows: 100(50%), 35(17. 5%), 10(5%), and 25(12. 5%) for E. coli, Staphylococcus, and Shigella, respectively. 30 (15%) did not show any bacterial growth, according vitek2 system which showed resistance of isolates to almost antibacterials drugs with slightly sensitive to some of which as (Enrofloxacin, Colistin, Ceftazidime, and Ciprofloxacin) in both sheep and calf.
