“…The infection occurs through the ingestion of food contaminated with the mites, containing the cysticercoid larva (Acha and Szyfres, 2003). Human cases have already been identified in Sri Lanka (Karunaweera et al, 2001;Amarasinghe et al, 2020), China (Sun et al, 2006), Vietnam (Xuan et al, 2003), Saudi Arabia (El-Dib et al, 2004), Argentina (Servia´n et al, 2020), andBrazil (Pac¸oê t al., 2003;Lopes et al, 2015). Most Nematoda identified have already been reported in domestic or wild pigs.…”

Tayassuidae Suidae Helminths Infectious diseases Zoonoses ConservationThis study identifies gastrointestinal parasites in the feces of Pecari tajacu (caititu) and Sus scrofa domesticus (domestic pig) in southeastern Piauı´, Brazil. The region covers 2 protected areas, Serra da Capivara National Park and Serra das Confuso˜es National Park, and surrounding communities. Fecal samples from 64 animals, 42 from domestic swine and 22 from caititu, collected between 1985 and 2013, were analyzed by optical microscopy. Helminths and/or protozoa were found in 64% of the domestic pig samples and 27% of the caititu samples, totaling 18 morphospecies:

“…Several studies conducted in both children and adults in Sri Lanka from 1924 to 2019, found that school children across the country were positive for hookworm, whipworm, roundworm and Bertiella infection, especially those living in urban areas ( Amarasinghe et al, 2020 ; De Silva et al, 1994 ; Sorensen et al, 1996 ; Gunawardena et al, 2011 ; Galgamuwa et al, 2016 ; Ediriweera et al, 2019 )., The reason attributed to Bertiella infections was that the main reservoir hosts, the toque macaques, were regular visitors to human settlements ( Amarasinghe et al, 2020 ), which may pose a threat, especially to small children as well as to domestic animals. Furthermore, alternations to the availability of foraging and roosting sites and the quality and quantity of food macaques consumed due to anthropogenic activities and urbanization, may lead in several ways to increase the parasite burden in macaque populations ( Weyher et al, 2006 ).…”

Understanding variations in host-parasite relationships with urbanization is vital for both, public health management and conservation of endemic animals with high anthropogenic interactions. Toque macaques ( Macaca sinica ) are such endemic old-world monkeys in Sri Lanka. Three macaque sub species inhabit the main climatic zones of the island; M . s. sinica , M . s. aurifrons and M . s. opisthomelas inhabit the dry zone, wet zone, and montane regions of the island, respectively. This study aimed to examine parasite prevalence in this host in association with urbanization. A total of 180 fecal samples were collected from the three sub species of toque macaques inhabiting the main climatic zones (dry, wet, and montane) in Sri Lanka; 20 samples each were collected from urban, suburban, and wild populations representing each climatic zone. Twenty gastrointestinal (GI) parasite genera types i.e . five types of protozoan cysts, two types of trematode ova, four types of cestode ova, eight types of nematode ova, and a single type of acanthocephalan ova were identified. The overall prevalence of parasites was 62% (112/180) with the highest prevalence of Strongyloides infection. In all three sub species, toque macaque populations with proximity to human settlements, including urban and suburban populations, manifested a greater GI parasitic prevalence, mean ova/cyst counts and species richness, compared to their wild counterparts. Importantly, records of five parasite types in toques in Sri Lanka are reported for the first time, while Moniliformis type was reported as a first record in free ranging macaques, globally. This study clearly demonstrated that human contact and habitat modification may influence patterns of parasitic infections in macaques. As most of the parasite types identified manifest zoonotic potential, with public health implications, close associations of macaques may cause a threat to human well-being.
