A Study On The Taxonomy & Prevalence Of The Species Of Genus Ancylostoma & Effects On Natural Infections On Various - 1993

The study was conducted to determine the prevalence of Ancylostomes (Hookworms) in dogs, taxonomy of the species of the Genus Ancylostoina and their effects on various blood parameters of the infected canines.

For above purpose, samples were collected from dog hospital, College of Veterinary Sciences and different pet clinics in the city.

Faecal and blood samples were stored in the refrigerator, of Parasitology Laboratory.

Only those dogs which had high prevalerit in Ancylostomes were examined by different faecal examination methods, were selected to get mature ancylostomes, after killing the dogs. Preservation and staining of Ancylostimes was carried out by adopting the prescribed methods. The taxonomy of the species of the genus Ancylostoma was studied with the help of keys.

The collective over all prevalence of different types of Ancylostomes recorded in stray and pet dogs was 28%.

The species of Ancylostomes identified in our area were: Ancylostoina Caninum, Ancylostoma braziliense and Ancylostoma duodene1e.

The percentage of the above mentioned species were 100%, 33% and 2.5% respectively. Blood of infected dogs were exposed to various haematological studies including Hb estimation, erythrocyte sedimentation rate (ESR), packed cell volume (PCV), total erythrocyte count (TEC), total serum protien level (TSP) and differential leukocyte count (DLC).
liaematological examinations were made to compare the blood picture of healthy and infected dogs. For this purpose 20 blood samples each from healthy and infected dogs were examined.

The results of haematological examination showed a significant decrease in haemoglobin estimation total erythrocyte count, packed cell volume and total serum protien level, whereas a significant increase in erythrocyte sedimentation rate and differential leukocyte counts, like neutrophils, eosinophils and very little increase in basophils were also seen.
