“…We believe that D. caninum and Taenia spp. were the most frequent parasites since, despite the extreme climatic conditions of Mexicali Valley, these parasites fulfill most of their biological cycle within the intermediate and definitive host [ 17 ]. T. canis was also one of the most frequent parasites detected, this nematode has a thick shell that enables egg survival in the external environment for many years and confers them resistance to the harsh environmental conditions in soil [ 18 ].…”

Stray dogs are one of the main reservoirs of intestinal parasitic infections and some have zoonotic potential. An epidemiological survey was carried out between September 2017 and May 2018 in Mexicali Valley, this area sacrifices around 92,470 head of cattle monthly, which represents 27% of the national slaughter and has 71,307 hectares for crops. In this period the Municipal Animal Control Center during their routine visits to the Mexicali Valley captured 103 dogs. All the dogs were evaluated using copromicroscopic techniques to detect intestinal parasites. The general frequency of parasitic infections was 28.15% (29/103), the most frequent parasite being Dipylidium caninum 16.50% (17/103), followed by Taenia spp. 6.79% (7/103), Taenia hydatigena 2.91% (3/103), Taenia serialis 0.97% (1/103), Taenia pisiformis (0.97%), Toxocara canis 3.88% (4/103), Toxascaris leonina 1.94% (2/103), and Cystoisospora spp. 1.94% (2/103). No significant statistical associations were found between parasitic infections and the studied variables (sex, age, and size) however; there was a significant statistical association with the capture area. Most of the parasites found in this survey have potential to affect the human population and animal production.

“…Irrespective of the results of direct microscopy, the samples were cultured on Sabouraud's Dextrose Agar (SDA) containing 0.5 mg/mL chloramphenicol and 500 mg/L cycloheximide. The plates incubated at room temperature (25-30°C), and examined daily for fungal growth for up to four weeks (11). Suspected fungal colonies were sub-cultured on SDA slants to obtain pure cultures, which were then sub-cultured on Potato Dextrose Agar (PDA) (Oxoid, UK) to facilitate distinctive spore formation.…”

“…The zoophilic dermatophytes may precipitate zoonoses in humans with these human infections resulting most often from direct contact with an infected animal or through indirect contact with contaminated environments (10), such as fungus-bearing hair and scales from infected animals. According to Akpolat et al, (11), the prevalence of superficial mycoses caused by zoophilic dermatophytes is significant worldwide, especially in the tropical countries with warm and humid climate, crowded living and poor sanitary conditions (12).…”

Background: Dermatophytosis (ringworm) is a zoonotic fungal skin infection caused predominantly by Microsporum canis, Microsporum gypseum and Trichophyton spp. It is highly transmissible and, while normally self-limiting, could be problematic due to its potential to cause disease in certain human populations. The occurrence and associated risk factors of dermatophytoses in dogs presented at three veterinary clinics in Osogbo, and Ilorin, Nigeria between July and November 2019 were investigated in this study. Methodology: This was a descriptive cross-sectional study of 325 dogs with lesions suggestive of dermatophytosis, selected by simple random sampling from three veterinary clinics in Osogbo and Ilorin, purposively selected for the study due to high patronage of the veterinary hospitals by dog owners. Using conventional mycological sampling techniques, plucked hairs and skin scrapings were obtained the dogs. The samples were emulsified in 10% potassium hydroxide, examined microscopically for fungal elements and cultured using standard mycological procedures. Information on dog demographic characteristics and risk factors for dermatophytosis were collected using structured questionnaire. The association between risk factors and demographic variables with the occurrence of dermatophytoses was determined using Chi-square test (with Odds ratio and 95% confidence interval) and p value < 0.05 was considered statistically significant. Results: Positive cultures for dermatophytes were obtained from samples of 48 (14.8%) dogs with M. canis 37.5% (18/48), M. gypseum 27.0% (13/48) and T. mentagrophytes 8.3% (4/48). Other fungi identified were Aspergillus flavus 12.5% (6/48) and Malassezia canis 12.5% (6/48). The age distribution of positive dogs were < 1 year (50.0%, n=24), 1-3 years (29.2%, n=14) and > 3 years (20.8%, n=10), while the risk factors associated with dermatophytosis included sex of dogs (p=0.0428), history of dermatophytosis (p<0.0001), clinical presentation (p<0.0001) and lesion type, especially kerion and pustular lesions (p=0.0297). Conclusion: These findings established the occurrence of dermatophytosis in dogs kept for companionship (i. e., pets), security and breeding purposes in the two States in Nigeria. Our findings underscore the need for routine mycological investigations in dogs to facilitate early detection of cases and prompt institution of treatment interventions, thereby preventing zoonotic transmission of dermatophytes to their owners, handlers and veterinarians.

“…Soil contact is an identified risk factor [1]. This may be due to GIT parasite-positive dogs with unrestricted movement defecating in the soil, contaminating it with parasite eggs and oocysts [25]. This could favor zoonotic transmission and the (re-)infection of other dogs [19,26].…”

Background and Aim: Canine gastrointestinal tract (GIT) parasites are of public health and veterinary concern and are harmful to both humans and animals. The risk of transmitting GIT parasites can be minimized depending on dog owners’ knowledge and management practices. Therefore, this study aimed to assess dog owners’ general knowledge and practices regarding GIT parasites. Materials and Methods: A structured questionnaire containing 10-point Likert statements was administered to 130 respondents in Cebu, Philippines, to obtain information about their profile (age, sex, civil status, and educational attainment) and data regarding their home environment, number of dogs and other pets owned, and their knowledge and practices regarding canine GIT parasites. These respondents had previously provided canine stool samples for fecalysis. Results: Most respondents were female (65.4%), 18–24 years old (55.4%), single (71.5%), and educated to college level (49.2%). Housing styles were mostly gated (76.9%), and >50% had a garden. The majority owned 1–3 dogs (56.9%) and did not own any other pets (73.8%). All knew about canine GIT parasites. There was a significant association between GIT parasite positivity in dogs and the owner’s sex (p = 0.005). Gastrointestinal parasite positivity was also associated with the owner’s knowledge about the transmission of parasites from the mother’s milk to her puppies (p = 0.001), canine intestinal parasites potentially causing weight loss, diarrhea, and vomiting (p = 0.001), and dogs potentially becoming infected with parasites from licking or sniffing the soil or grass where other animals have been (p = 0.005). Moreover, there was a significant association between GIT parasite positivity and the owner’s practice of daily cleaning of the areas where the dog defecated (p = 0.001), deworming every 6–12 months (p = 0.001), and unfailingly following the vaccination and deworming schedule (p = 0.006). Finally, the summative knowledge and practice level of the owners were significantly associated with GIT parasite positivity (p = 0.001). Conclusion: This study highlights the need for continuous education of dog owners to maintain good knowledge and practices to prevent GIT parasite infection. Frequent deworming (once a month) of adult dogs is recommended. Keywords: dogs, intestinal parasites, soil, vaccination.
