Antibiogram test
No significant correlation between neither different age groups nor different sexes of the horses and sensitivity of the eyes’ bacterial flora to Colistin, ceftiofur, florfenicol, amoxicillin, and ampicillin was indicated using Chi-squared and Fisher exact statistical tests (P>0.05) (Tables 3,4). However, unlike trimethoprim-sulfamethoxazole, significant differences in sensitivity to enrofloxacin, as well as ciprofloxacin between age groups of 1-5 and 5-10 along with 1-5 and older than 10, were indicated (p<0.05) (Table 5). Among all utilized antibiotics, only differences in sensitivity to trimethoprim-sulfamethoxazole were significantly correlated with the sex of horses in which neutered horses and intact mares were significantly different (p<0.05) while the difference between mare and stallion was insignificant (Table 6). As shown in Tables 5 and 6 since all isolated bacteria were sensitive to gentamicin and neomycin, statistical analysis was not possible.
