Antibacterial efficacy of Moringa oleifera leaf extract against pyogenic bacteria isolated from a dromedary camel (Camelus dromedarius) abscess.

Abscess in camel is one of the most important bacterial infections. It causes anemia and emaciation, resulting in an economic loss due to carcass condemnation and a decrease in reproductive and production efficiency.

This investigation aimed to isolate the bacteria from abscesses in camels and evaluate the antibacterial activity of Moringa oleifera extracts.

Disk diffusion method and minimum inhibitory concentration were used for the evaluation of the antibacterial activity of M. oleifera extracts against isolated bacteria from camel abscesses.

The isolated bacteria were displayed relatively as follows: Corynebacteriumpseudotuberculosis (30.4%), Staphylococcus aureus (25.8%), Escherichiacoli (17.8%), Corynebacteriumulcerans (10.5%), Klebsiellapneumoniae (8.5%), Pseudomonas aeruginosa (8.5%), Micrococcus spp. (6.7%), Proteus vulgaris (5.2%), Citrobacter spp. (4.2%), and Staphylococcus epidermidis (1.7%). The drugs of choice for Corynebacterium isolates were ciprofloxacin and trimethoprim/sulfamethoxazole, whereas amikacin, ciprofloxacin, gentamicin, neomycin, novobiocin, streptomycin, and vancomycin were for Staphylococcus isolates. Moreover, the ethanol extracts of M. oleifera showed higher antibacterial efficacy than the cold aqueous extracts.

M. oleifera is considered one of the new infection-fighting strategies in controlling pyogenic bacteria responsible for camel abscesses.
