Pathological and Bacteriological study of Dog Skin Disease In Iraq Governorates

Abstract

Askin disease is the most important organ in the body and it's the first line of defense mechanism which account 15-25% of animal total body weight current study aimed to isolation the pathogenic bacterial from dog skin in Iraq Governorates (Baghdad, Erbil, Anbar, Sulaymaniyah) During a period 6 months (January-June) 2023. 200 different breed, sex, edge dogs K9, ornamental and stray dog were examined.

Investigation the gross and microscopic pathological change with clinical signs of bacterial effected dog skin. by using diagnostic tools for that swabs are taken using a sterile cotton swab containing nutrition broth until the bacteria grow.   After taking the swab, the lesion site is sterilized and a sample is taken using Biopsy punch with a diameter of 8 mm.

The swab was transferred to the laboratory to be cultured in dishes containing culture media. The samples taken by Biopsy punch were also preserved in formalin and then transferred to the tissue cutting unit to make slides.

Results revealed pathogenic bacteria in media and VITEK® 2 Compact system from 200 samples 100 sample where pathogenic bacterial isolate as following 50% Staphylococcus pseudintermedius 20% Proteus Mirabilis 20% pseudomonas aeruginosa and 10% Escherichia coli clinical signs and gross lesion revealed skin allopecia, ulcer, red odema, pedunculate cauliflower nodules, dermatofibroma and Papilloma. While microscopic lesion revealed skin ulcer, hyperplasia acanthosis, hyperkeratosis, granulation tissue with apoptosis, necrosis poly and mononuclear inflammatory cells abscessation.
