Abstract
The present study demonstrated bacterial etiology of skin affections and their antibiogram profiling of different animal species of various age groups. A total of 255 samples from cattle, buffalo, dogs, goats, sheep, camel and horses were collected over a period of two years (2012-2014) from Mathura, (U.P.) India, and nearby surrounding areas. Clinical samples were collected from variety of skin disorders, subjected to laboratory isolation and identifica- tion as per standard protocols. The bacterial infection, Staphylococcus aureus, was the most common isolate (36.22 %), followed by E. coli (34.59 %), Pseudomonas (20.54), Bacillus (16.21), Klebsiella (12.43), Micrococcus spp (8.11 %), Strep- tococcus pyogens (7.56), Proteus (6.49), Clostridium (3.78), Gram negative non-lactose fermenter (2.7%), Gram positive non-spore producing bacilli (2.16) and Fusobacterium (0.54 %). Bacterial isolates obtained were subjected to in vitro antibiotic sensitivity testing by disc diffusion method against 23 commercially available antimicrobial discs. Results of the current study revealed maximum sensitivity to gatifloxacin (94.03%), amikacin (85.7%), mild sensitivity to spar- floxacin (44.85%) and gentamicin (43.48%); emergence of multi-drug resistant bacterial strains of Staphylococcus aureus, Pseudomonas aeruginosa, E.coli appeared to be an important finding. Present study is intended to document the complex microbial inhabitants of wounds from animals and their antimicrobial sensitivity pattern and strongly recommended the use of antimicrobial sensitivity testing to know the rapidly changing pattern of antibiotic activity. The study will further aid to the existing literature for planning new alternative therapeutic strategies against rising global health havoc of multidrug resistance.
Highlights
Skin affections including wound infections are frequent complications following lacerations, injuries, penetrating trauma, animal fights, bites etc
Due to paucity of significant work done over animals in this regard, the current study was performed to explore the blueprints of bacterial agents involved in various types of wounds and skin infections with the history of being unresponsive to earlier treatment in different animal species of various age groups, and their sensitivity pattern was assessed against commonly used antibiotics
Present study mainly focused on screening of bacterial agents involved in cases of skin infections, wounds and from abnormal skin growth from variety of animal species which were unresponsive to earlier treatments
Summary
Skin affections including wound infections are frequent complications following lacerations, injuries, penetrating trauma, animal fights, bites etc. Due to paucity of significant work done over animals in this regard, the current study was performed to explore the blueprints of bacterial agents involved in various types of wounds and skin infections (chronic, deep suppurative, open, gun-shot, lacerated, incised, ulcerated wounds etc.) with the history of being unresponsive to earlier treatment in different animal species (cattle, buffalo, goat, horse, camel, sheep, dog) of various age groups, and their sensitivity pattern was assessed against commonly used antibiotics. A total of 255 samples of wound and skin affections with the history of being unresponsive to earlier treatment were collected from various animal species including cattle, buffalo, goats, sheep, horses, dogs and camel, irrespective of gender and age to screen the cases of superficial wounds and skin infections of animals for bacterial causes from clinical cases and field in and around the Mathura city (Table 1).
