Isolated bacteria
The relative frequency percentage of the isolated bacteria from studied horses’ eyes is indicated in Table 2 and Figure 1. The most frequently isolated bacterial was Bacillus cereus (24.75%) followed byMicrococcus luteus (11.88%), Bacillus licheniformis(10.89%), Pasteurella multocida (10.89%), Bacillus mutans (8.91%) Staphylococcus spp. (6.93%),Staphylococcus epidermidis (4.95%), alpha-hemolyticstreptococcus species (4.95%), Trueperella pyogenes(3.96%), Corynebacterium spp. (3.96%), Bacillus subtilis(2.97%), Corynebacterium pseudotuberculosis (1.98%),Listeria monocytogenes (0.99%), Actinomyces spp. (0.99%), Corynebacterium bovis (0.99%) and Mannheimia haemolytica (0.99%). There were no significant differences betweenBacillus cereus , Bacillus licheniformis , Micrococcus luteus , Pasteurella multocida , Bacillus mutans ,Staphylococcus spp., Bacillus subtilis, alpha-hemolyticstreptococcus species, Trueperella pyogenes ,Staphylococcus epidermidis , and Corynebacterium pseudotuberculosis isolated from eyes of 17 horses using chi-squared and Fisher exact tests(p>0.05). Statistical analysis of the frequency of Listeria monocytogenes , Actinomyces spp.,Mannheimia haemolytica, and Corynebacterium bovis was not possible due to isolating each of them from one individual horse.
