“…[10]. They are commonly classified into soil-transmitted helminth (STH) groups [11]. Some types of STH worms that infect dogs have been reported as zoonotic agents, namely, Ancylostoma ceylanicum, Available at www.veterinaryworld.org/Vol.14/February-2021/16.pdf Ancylostoma caninum, and Toxocara canis [12].…”

Background and Aim: Several free-roaming dogs can be easily found in the public areas of Bali. They go out in search of foods and friends and defecate everywhere. In general, these groups of dogs do not receive good healthcare from their owners and are generally threatened by some disease-causing organisms, especially helminths. This study was conducted to identify and measure the prevalence of soil-transmitted helminths (STHs) that cause infection in free-roaming dogs in Bali Province, Indonesia. Materials and Methods: A total of 1611 fresh dog fecal samples were collected from all areas of Bali Province and subjected to qualitative fecal examination using flotation techniques to obtain STH eggs. Results: The incidence of STHs in free-roaming dogs was 38.36%. However, three types of STHs were identified, including Ancylostoma spp., Ascaris spp., and Trichuris spp. Ancylostoma spp. had the highest prevalence of 37.8%, followed by Ascaris spp. and Trichuris spp. at 6.02% and 0.87%, respectively. Multiple infections of these worms were also recorded. The polyparasitism prevalence of Ancylostoma spp. and Ascaris spp. was 3.85%, followed by that of Ancylostoma spp. and Trichuris spp. at 0.5% and that of Ascaris spp. and Trichuris spp. at 0.06%. There were no altitude-wise differences in the prevalence of STH infection. Conclusion: The prevalence of STHs was high in free-roaming dogs. This finding necessitates more serious attention as it affects both animal and public health.

“…Other authors in similar studies also verified the presence of this helminth in fecal samples (Bricarello et al, 2018;Ferraz et al, 2019). It is a parasite of zoonotic importance, with a direct life cycle and infection occurs through the ingestion of embryonic eggs contained in the soil (Di Cesare et al, 2012;Jia-Chi et al, 2016). Despite few cases reported in humans in the past with Trichuris vulpis, it is considered a parasite of zoonotic importance as a causative agent of visceral larva migrans (Sakano et al, 1980) and intestinal infections in humans (Dunn et al, 2002).…”

In Brazil, dogs and cats have free access in public areas in some cities, such as squares, parks and beaches, despite restrictive laws for their permanence in these places. Animals infected with intestinal parasites contaminate the environment through their feces. The present study aimed to verify the occurrence of helminth eggs, oocysts and protozoan cysts in stool samples from three beaches in Greater Florianópolis, Santa Catarina, Brazil, from March 2017 to April 2018. Stool samples were processed by the Willis-Mollay flotation technique and the Hoffman sedimentation technique. The percentage of 47.65% of positive samples for helminths or protozoa was found on the southern beaches of Florianópolis island, with an occurrence of 52.78% at Morro das Pedras Beach and 42.86% at Campeche Beach. At Pinheira beach, in Palhoça, 56.66% of the samples were contaminated with one or more zoonotic parasites. In this study, the most prevalent parasites on the three beaches analyzed were hookworms and Trichuris vulpis, followed by Giardia spp. and Cystoisospora spp. Samples containing Toxocara spp. eggs were collected at Pinheira beach. It is concluded that the contamination of the beaches in the present study constitutes a public health problem, considering the possibility of zoonoses transmission. The importance of implementing sanitary programs for the control of parasites in dogs and cats is emphasized, as well as awareness and education programs, in order to reduce environmental contamination in public places.

“…Dogs and pigs are also known to harbour STHs reported to be zoonotic in different parts of the world. These zoonotic STHs include hookworms: Ancylostoma and Toxocara species in dogs, as well as Ascaris and Trichuris species in pigs [3][4][5][6]. The accurate diagnosis of STH infection plays a very important role in the treatment, prevention, and control of the parasites.…”

Soil-transmitted helminth (STH) infections are caused by roundworms, hookworms, whipworms, and thread worms. Accurate diagnosis is essential for effective treatment, prevention, and control of these infections. This study evaluates a new diagnostic method called Single-image Parasite Quantification (SIMPAQ), which uses a lab-on-a-disc (LoD) technique to isolate STH eggs into a single imaging zone for digital analysis. The study evaluates the purification performance of the SIMPAQ technique for detecting STH eggs in animal samples. This was a cross-sectional study conducted among 237 pigs and 281 dogs in the Morogoro region in Tanzania. Faecal samples were collected and processed with the LoD technique, as well as flotation and McMaster (McM) methods for comparison purposes. The overall prevalence of STH infections was high as per the LoD technique (74%), followed by McM (65.44%) and flotation (65.04%). Moreover, the overall performance of the LoD technique, using McM as the gold standard, was 93.51% (sensitivity), 60.89% (specificity), 81.91% (PPV), and 83.21% (NPV). The LoD technique exhibited high prevalence, sensitivity, and NPV, which demonstrates its value for STH egg detection and its crucial role in the era of accurate STH diagnosis, promoting proper management of the infection.
