“…(Figure 2). This prevalence levels have been reported in several previous studies in Brazil (Oliveira-Arbex et al, 2017;Ramos et al;2020;Silva et al, 2020;Lima et al, 2021;Souza et al, 2023;Ugalde et al, 2023) and other countries, such as Mexico (Torres-Chablé et al, 2015), Algeria (Ziam et al, 2022), Nepal (Sukupayo & Tamang, 2023), Morocco (Idrissi et al, 2022) and Ecuador (Calvopina et al, 2023). Since most of the dogs investigated are adults, this data aligns with the literature, as infections by hookworms are the most common in adult dogs (over one year old) (Ferreira et al, 2016;Lima et al, 2021;Souza et al, 2023), and Toxocara sp.…”

The coproparasitological examination of dogs (n=278) from two Brazilian biomes (Amazon [AZ] and Atlantic Forest [AF]) by centrifugal flotation demonstrated positivity values of 54.2% (AF) and 48.5% (AZ). The most prevalent parasites in AF were hookworms (81.0% - 47/58), Toxocara sp. (17.3% - 10/58) and Trichuris vulpis (12.1% - 7/58); while in AZ they were hookworms (86.7% - 72/83), Toxocara sp. (18.1% - 15/83), Dipylidium caninum (13.3% - 11/83) and T. vulpis (10.8% - 9/83). PCR was performed using the partial mitochondrial genes cytochrome c oxidase subunit 1 (pcox1) and NADH dehydrogenase 1 (pnad1) in 25 fecal samples positive for Toxocara sp. eggs and found one sample positive for pcox1 and six positives for pnad1. The sequencing of these samples was unsuccessful due to the difficulties inherent in copro-PCR+sequencing. The sequencing of 14 samples of T. canis adult helminths retrieved 11 sequences of 414 bp for pcox1 and nine sequences of 358 bp for pnad1. The phylogenetic trees of these sequences confirmed the species T. canis. Intraspecific genetic variation was only observed for pnad1. This is the second study involving molecular analysis of T. canis in dogs from Brazil and adds new information through the use of pnad1.

“…In this investigation, a 50.20% prevalence rate of canine ancylostomiasis was determined, which is similar to the prevalence rate reported in urban and rural areas worldwide (40–100%) [ 26 ] and very close to the higher prevalence rate of 60% reported in endemic areas of South America [ 27 ]. The prevalence rate observed in this study is higher than that of domestic dogs in Europe, which is 1.7–33% [ 28 ]; and it is within the range of prevalences described in Asia 3.5% [ 10 ] to 79.1% [ 29 ], Africa 31.9% [ 30 ] to 53.8% [ 31 ], and Australia 6.9% [ 32 ] to 77.3% [ 33 ].…”

Background Ancylostoma spp. , including A. duodenale, A. braziliense, A. caninum, and A. ceylanicum, are hookworms that are transmitted from infected soil and by contact with domestic animals and rodent hosts, and can cause systemic disease and cutaneous larva migrans. The objective of this study was to describe the ecoepidemiology of Ancylostoma caninum and Ancylostoma spp. in urban-marginal sectors and in rural sectors located in Ecuador. Material/Methods Through addressed sampling, a total of 498 domestic dogs and 40 synanthropic rodents were analyzed via the following coproparasitic methods: direct, flotation, sedimentation with centrifugation using saline (egg identification), modified Baermann (larval identification), and morphometric methods (confirmation). A total of 236 people were surveyed, and a clinical analysis was performed via physical examination. The environmental variables were obtained through reports from the INAMHI of Ecuador and the use of online environmental programs. Through surveys, data related to social determinants were obtained. Epidemiological indicators (prevalence, morbidity, and mortality) were obtained through microbial analysis and surveys. Results A total of 250 domestic dogs were diagnosed with Ancylostoma caninum (50, 20%), and 41 were diagnosed with Ancylostoma spp. (8.23%). One synanthropic rodent (2.5%) was positive for A. caninum . In the clinical analysis, 3 patients were identified as positive (1.27%) for cutaneous larva migrans (CLM). Likewise, environmental variables and social determinants influence the transmission, prevalence, and nature of parasitism by hookworm. Conclusions People, domestic dogs, and rodents were infected with these parasites. Consequently, there is a risk of ancylostomiasis and cutaneous larvae migrans spreading.

“…Human acquisition of parasite‐borne zoonotic diseases follows direct contact with infected dogs or exposure to the environment, food or water contaminated with dog's faeces (Schantz, 2007). The zoonotic parasites have been predominantly found with the prevalence rates ranging from 44.3% to 100% in feral dog population from global geographies, like India, China, Morocco, Nigeria and Uruguay, especially in the rural setting (Ayinmode et al., 2016; Fang et al., 2015; Idrissi et al., 2022; Malgor et al., 1996; Traub et al., 2002). On the other hand, 15% of clinical cases and 93% sero‐prevalence of canine‐specific Ancylostoma spp.…”

BackgroundThe presence of intestinal parasites influences the growth and well‐being of canids. Additionally, infected dogs and their faeces with considerably higher eggs/oocysts released per gram (epg/opg) of zoonotic parasites contribute to parasitic spillover to humans, domestic animals and sympatric wildlife.ObjectivesThe current study aimed to reveal the prevalence of intestinal parasites (protozoa and helminths) and to list the zoonotically significant parasites in free‐roaming street dogs in Lalitpur Metropolitan City, Nepal.MethodsFresh faecal samples (n = 332) were collected from feral dogs of varying ages and sexes and transported to the research laboratory. The copro microscopic examination was carried out via direct wet mount, formalin ethyl acetate sedimentation, saturated salt flotation, acid‐fast staining and sporulation techniques.ResultsCoproscopy revealed an overall 95.7% (318/332) prevalence rate with 23 diverse species of intestinal parasites (10 protozoa and 13 helminths). Among them, 5 protozoa and 11 helminths possessed zoonotic potential, and their overall prevalence was 92.5%. Helminth's overall prevalence was double that of the protozoa (87.7% vs. 43%). Polyparasitism was dominant over mono parasitism (79.5% vs. 16.3%), and co‐infection of up to seven species of parasites at a time was recorded.ConclusionsUrban street dogs harboured a higher prevalence of intestinal parasites that varied with age and sex. Since most of the reported parasites are zoonotic, dog density and parasitic richness indicate a greater spillover risk to humans and domestic animals. Furthermore, this study also provides appropriate ‘baseline’ data for assessing effective control measures against parasitic infestations among street dogs and controlling their transmission to humans.
