Gastro intestinal parasites in Stray dogs in Ethiopia

Gugsa, G., Hailu, T., Kalayou, S., Abebe, N., & Hagos, Y. (2015). Prevalence and Worm Burdens of Gastro-Intestinal Parasites in Stray Dogs of Mekelle City, Tigray, Ethiopia. American-Eurasian J. Agric. & Environ. Sci., 15 (1): 08-15

Stray dogs (Canis familiaris) are ownerless native dogs of mostly non descriptive nature which roam
freely without human supervision and gastrointestinal parasites are common pathogens in these dogs and some are reservoirs of parasitic infections of humans. A study on gastrointestinal parasites of free roaming dogs was conducted from November 2009 to April 2010 with the objective of determining the prevalence and intensity of GI parasites of stray dogs and documenting the helminth biodiversity of stray dogs so as to provide baseline information on GI parasites infection of stray dogs on a local scale in Mekelle city. A total of 11 stray dogs were captured and euthanized. Necropsy finding was done and the contents of their alimentary canal were inspected. Statistical tests were performed using SPSS 15.0 windows version. The necropsy finding revealed that 72.72% free roaming dogs were found to be harborcestodes, nematodes and mixed infections. Five species of cestodes and two species of nematodes were found to be adult worms in their respective hosts. The highest parasite burdens (72.72%) were found for S. lupi and D. caninum and the lowest parasite burden was recorded for T. serrata (9.1%). The sex of the euthanized dogs had a significant difference in the prevalence of GI helminthes in the two sexes (p<0.05). Female dogs (100%) were found to be more likely infected by gastrointestinal helminthes than male dogs (62.5%). From the whole gastrointestinal parasites, the highest and lowest mean worm burdens were seen for S. lupi (9.13) and T. serrata (1), respectively. Of these reported parasites some of them have public health importance but dogs harbouring the parasites are living freely and friendly with the public. Hence, there should be a practice of regularand appropriate stray dogs control and health management of owned dogs. In addition, further epidemiological studies should be conducted to investigate the rate of seasonal infection and the level of environmental contamination
