Antibiotic resistance among staphylococcus species isolated from beef minced meat in north Khartoum locality

الملخص EN

This study measured the prevalence of antibiotic resistant among Staphylococcus species in minced beef meat at North Khartoum locality through identifying Staphylococcus species in minced meat and detecting the profile of resistance among Staphylococcus spp.

Some tests have been done to identify the Staphylococcus spp, using Gram stain and coagulation tests.

A sugars test (maltose, sucrose, lactose, and mannose) has been used to identify the negative staphylococci coagulation.

Staphylococcus aureus, which is more saprophytic cause of urinary tract infections, were identified by their resistance to novobiocin.

Mannitol agar was used as a selective medium and blood agar to confirm.

It was obtained that fifty Staphylococci strains were isolated from minced meat and identified as follows : 46 % of isolates were identified as S.aureus, 36 % of isolates were identified as S.delphini.

10 % of isolates were identified as S.

Pulveriri.

The highest resistance to antibiotics used was observed to penicillin.

Approximately 35 % of S.aureus, 22 % of S.

Dilphini, 60 % of S.

Pulveriri and 50 % of S.

Hyicus isolates were resistant to penicillin.

61 % of S.aureus and 67 % of S.delphini were also resistant to novobiocin.

It will concluded that, S.

Aureus appeared to be a major frequent bacterial contaminant of minced meat.

Some isolates of staphylococci species showed mutants to tetracycline and novobiocin.
