“…eggs was found 5.2% of fecal samples. This finding is in accordance with the results of earlier studies in Iran [ 5 , 21 ]. This prevalence rate may appear low; indeed, fecal examination might underestimate the number of helminths eggs, especially those of cestode and proglottids compared to necropsy [ 22 , 23 ].…”

Parasitic helminth infections of dogs, wolves, foxes, and golden jackals in Mazandaran Province, North of Iran

et al. 2020

Background and Aim: There is a large amount of information on intestinal parasites in stray dogs and golden jackals (Canis aureus) in Mazandaran Province, Iran. However, there is little information about foxes and wolves, which have a potential role in the spread of dangerous parasitic diseases, such as echinococcosis and toxocariasis. The aim of the present study was to identify the genus or species of parasitic worms in stool samples obtained from carnivores in Mazandaran Province, Iran, from August 2017 to April 2018. Materials and Methods: A total of 274 fecal samples were collected from carnivores, including dog, fox, wolf, and C. aureus in three areas of Mazandaran Province, Iran. All specimens were examined by centrifugal fecal flotation using a solution of Sheather's sugar to detect helminths eggs. Then, all samples were assessed using a light microscope. Data analysis was performed by SPSS version. 18 (Chicago, IL, USA). Results: In this study, seven genera of helminths were observed, including Ancylostoma, Uncinaria, Toxocara, Dipylidium, Toxascaris, Taenia, and Spirocerca. The prevalence of helminth infections was 97.7% (127 out of 130), 56.7% (51 out of 90), 51.4% (18 out of 35), and 52.6% (10 out of 19), among dogs, C. aureus, foxes, and wolves, respectively. The highest prevalence of Ancylostoma and Toxocara infections occurred in the eastern and central areas of the province (42.1% and 35.7%, respectively). Conclusion: Based on the results of this study, the infection with intestinal zoonotic helminths in carnivores was an important public health factor in Mazandaran. Therefore, these infections can be potentially harmful to humans and other animals.

IntroductionDogs harbour zoonotic parasites that cause serious infections in humans, such as visceral larva migrans, ocular larva migrans, cystic echinococcosis, and alveolar echinococcosis. Studies on dogs’ gastrointestinal parasites in different geographical locations are required to increase knowledge of the risk of canine zoonoses in human populations.Material and MethodsThe presence of parasites was examined in 450 faecal samples collected from eight zones of Zanjan province, northwest Iran from June to November 2015. The samples were examined using the sedimentation concentration method and modified Ziehl-Neelsen staining.ResultsGastrointestinal parasites were found in 86 (19.1%) faecal samples. Sarcocystis spp. (7.3%), Taenia/Echinococcus spp. (5.6%), Toxocara spp. (1.8%), and Cystoisospora spp. (1.6%) were the most common parasites observed. The other detected parasites consisted of Dicrocoelium dendriticum (0.7%), Eimeria spp. (0.7%), Cryptosporidium spp. (0.4%), Physaloptera spp. (0.4%), Giardia spp. (1.3%), and Spirocerca lupi (1.3%). The lowest parasite infection rates belonged to Trichuris vulpis and Acanthocephalans (0.2% each).ConclusionThis study provides current information on the infection rates in dog populations in Zanjan Province. Furthermore, the study shows a high prevalence of gastrointestinal parasitic infections, including zoonotic ones and particularly Taenia/Echinococcus spp., potentially transmissible to humans and thus relevant to public health.

“…Reported prevalence of Taenia spp. in dogs' faecal samples range from 0.06 to 6.9% (Dyachenko et al, 2008;Cantó et al, 2011;Kohansal et al, 2017). The diagnosis of echinococcosis or taeniasis through the detection of the eggs in faeces is not definitive because the eggs of Echinococcus spp.…”

“…In practice, often times treatment of dogs for taeniid infection commences at this simple diagnostic stage. The prevalence of taeniid eggs in dogs' faeces is reported to be from as low as 0.25% to as high as 73.2% in different parts of the world (Dyachenko et al, 2008;Beiromvand et al, 2013;Swai et al, 2016;Kohansal et al, 2017) There is suspected presence of human echinococcosis in Nigeria (WHO, 2011). Few previous studies have attempted to report the prevalence of echinococcus or taeniid infections in stray dogs in Nigeria (Dada et al, 1979;Arene & Nweke, 1985;Ugochukwu & Ejimadu, 1985;Adediran et al, 2014).…”

Human association with taeniid infected dogs could pose risk of infection. Few studies exist on prevalence of taeniid infections in dogs in Nigeria, however, none have attempted to determine extrinsic factors associated with the prevalence among owned dogs. This study, therefore, aimed at determining taeniid infection and its associated intrinsic and extrinsic factors among owned dogs in Ibadan, Oyo State, Nigeria. A cross sectional study involving the screening of 185 dog faecal samples using the floatation method was done. Questionnaire was used to obtain data on intrinsic factors such as age, gender, breed; and extrinsic factors such as management and hygienic practices and environmental factors from participating dog owners. Data obtained were analysed using descriptive statistics and Fisher's exact test at α0.05. The mean age of the respondents was 35.7 ± 11.3 years, while the median age of the dogs was 20 months (Interquartile range 10.5 – 40). The prevalence of taeniid infection was 4.87%. Extrinsic factors such as the water source – tap water (Odds Ratio (OR): 5.5; 95% Confidence Interval (CI): 1.01, 36.8) and the feed types – dry foods (OR: 11.4; 95% CI: 1.1, 159.3) were significantly associated with taeniid infection. None of the intrinsic factors was significantly associated with taeniid infection. Taeniid infection is low among owned dogs in the study area. Source of water and the food type to dogs could be possible source of taeniid infection to dogs. Proper dog deworming and provision of clean water source could help reduce taeniid infection in dogs.
