Abstract
Background and Aim:Uncinaria infection often appears in domestic dogs. In the present study, parasitological examination of fecal samples from 782 dogs were analyzed for the presence of Uncinaria stenocephala.Materials and Methods:Fecal samples were analyzed by means of a standardized flotation method using a saturated salt solution containing NaNO3 (specific gravity 1.38), with a centrifugation step.Results:The highest prevalence rates were found among young adult dogs (8.3%), followed by puppies (5.4%); the lowest prevalence rates were found in dogs older than 3 years (4.3%). The prevalence was 5.8% among female dogs and 7.2% in male dogs. Coinfections with roundworms and protozoan parasites were frequently observed in U. stenocephala-positive dogs (15%). In total, three types of coinfections were registered. Coinfection of U. stenocephala + Sarcocystids oocysts was recorded in 19.1% of the dogs (n=10). This may relate to higher prevalence of S. oocysts in dogs (n=153; 19.5%). There were two cases of coinfection of U. stenocephala + Toxocara canis (3.9%), which may relate to low prevalence of T. canis (3.9 %). One case of coinfection of Dipylidium caninum + U. stenocephala (0.1%) also appeared.Conclusion:The present study showed that male dogs and young dogs were most susceptible to U. stenocephala infection.
Highlights
Hookworms are the most prevalent intestinal parasites of domestic dogs and cats
The larval stage of A. caninum is implicated in cutaneous larva migrans (CLM), which leads to common follicular dermatitis [2]
Eggs of U. stenocephala eggs were found in fecal samples from 51 dogs (6.5%) aged between 1 month and 8 years
Summary
Hookworms are the most prevalent intestinal parasites of domestic dogs and cats. The most common canine hookworms (Nematoda and Strongylidae) are Ancylostoma caninum, Ancylostoma braziliense, Ancylostoma ceylanicum, and Uncinaria stenocephala. A. caninum is a dog-specific parasite, while A. braziliense, A. ceylanicum, and U. stenocephala affect both dogs and cats [1]. Hookworms cause zoonotic diseases and have public-health significance [2]. The high frequency of occurrence of the larval stage of A. braziliense causes hookworm-associated cutaneous larva migrans (CLM). The larval stage of A. caninum is implicated in CLM, which leads to common follicular dermatitis [2]. Uncinaria infection often appears in domestic dogs. Parasitological examination of fecal samples from 782 dogs were analyzed for the presence of Uncinaria stenocephala
