Heaith hazard of antibiotic resistance enterococci isolated from row camel milk

الملخص EN

Enterococci spp.

were isolated and identified from Camel milk samples in order to evaluate its sensitivity pattern to common use antibiotics.

Thirty milk samples were randomlyobtained from local vendors and seller of camel milk from different zones in Upper Egypt (Arment city, Edfoo city and Daraw city).

Enterococci were isolated and enumerated using KF Streptcoccal culture media, identified using bio-chemical tests.

HemolIysin activity of E.fecalis was done.

The study focused on the resistance patterns of the selected hemolytic and non hemolytic E.fecalis strains to 6 antimicrobial active agents (Gentamycin, Nalidixic acid, Ampicillin, Oxytetracclin, Neomycin and Novobiocin).

36.66% of Camel milk samples were positive for enterococcus with a mean count of 1.72 x 104 ± 3.86 x 103cfu / ml, 14different strains were isolated, where, E.fecalis corresponded to 64.28 % hemolytic E.

fecalis to 7.14 %, E.facium 14,28 and eachE.

durans and E.hirai 7,14 %.

All isolates identified showed an important resistance to the antibiotic tested (singly or in combination) Ampicillin, Nalidixica acid and Neomycin showed the high resistance.

However, Novobiocin is considered sensitive.

The abundance of isolates showing multi drug resistance suggests that the sanitary quality of camel milk should be improved to decrease the incidence of enterococci.
