Estudo da prevalência de endoparasitos em fezes de cães domiciliados na zona norte de Porto Velho, Rondônia, Brasil

Abstract

É necessária a identificação das endoparasitoses mais comuns, pois algumas podem ser caracterizadas como zoonoses. Dentre as possíveis infecções, destacam-se Ancylostoma spp. e Toxocara canis. Os principais sintomas de infecção observados são desarranjo gastrointestinal, emagrecimento e vômito. Este estudo teve como objetivo identificar as endoparasitoses mais comuns em cães domiciliados na zona norte de Porto Velho-RO, destacando a principal e criando um parâmetro do risco de possíveis zoonoses para a população. Foram coletadas 40 amostras de fezes de cães no período de setembro a novembro de 2019 e feito a análise microscópica utilizando a técnica de Willis e Mollay para preparação das lâminas. Em 40 amostras, 35 foram constadas presença de ovos de helmintos, sendo o mais prevalente identificado o Ancylostoma spp.

Parasitosis in Pet Dogs from Rondônia, Amazon Biome, and Human Perception of Zoonoses

“…Our findings revealed a significant proportion of infected pet dogs in the municipality of Rolim de Moura, underscoring the necessity for further investigation given the substantial sample size. Previous studies showed a high prevalence of gastrointestinal parasite infections in pet dogs in two cities within the state, where infection rates reached 84.2% (72/95) and 87.5% (35/40) [9,10]. Correspondingly, similar research conducted in other states of the northern region also reported elevated infection rates.…”

“…This region is renowned for its biodiversity but faces substantial anthropogenic pressure due to extractive activities and agricultural potential [7]. Gastrointestinal parasitosis in dogs is highly prevalent in this region, exceeding 80% in certain areas [2,[8][9][10]. However, there is a dearth of data regarding pet dog owners' perceptions of parasitic diseases in dogs and their significance as zoonoses in this region, despite the existence of perception studies conducted in other areas of Brazil and globally [3,[11][12][13].…”

Occurrence of gastrointestinal parasites in dogs from Cuiabá, Mato Grosso

“…Ancylostoma spp. is frequently diagnosed in canine parasitological surveys and have been reported as the most frequent nematode genus in dogs in Brazil (Alves et al, 2005;Labruna et al, 2006;Oliveira et al, 2009;Pereira & Barbosa, 2013;Andrade et al, 2015;Snak et al, 2019;Lopes et al, 2021;Lusa et al, 2021).…”

“…Around the world, there are some reports of gastrointestinal parasitism in dogs, and the frequencies of the parasites detected were 26.5% (80/302) in Villahermosa, Mexico (Torres-Chablé et al, 2015); 40% (120/300) in Central Queensland, Australia (Gillespie & Bradbury, 2017); 26.8% (41/152) on the Lower Dir district, Pakistan (Khan et al, 2020); 63.5% (148/233) in northern Spain (Regidor-Cerrillo et al, 2020); and 11.9% (43/360) on the Shendi area, Sudan (Sulieman et al, 2020). Likewise, different occurrences are reported in Brazil, 20.5% (635/3099) in São Paulo (Ferreira et al, 2016); 43.2% (147/340) on the northeastern region (Zanetti et al, 2019); 72.55% (74/102) in Caxias do Sul (Lusa et al, 2021); and 87.5% (35/40) in Porto Velho (Lopes et al, 2021). In the midwestern region, occurrences of 48.3% (97/201) were found in Goiânia (Oliveira et al, 2009) and 85% (85/100) in Cuiabá (Ramos et al, 2015).…”

“…Some of the helminths that most frequently infect dogs are Ancylostoma spp., Toxocara spp., Trichuris vulpis, and Dipylidium caninum, and the most common protozoa are Giardia duodenalis and Cystoisospora spp. (Curi et al, 2017;Kostopoulou et al, 2017;Mircean et al, 2017;Saldanha-Elias et al, 2019;Snak et al, 2019;Regidor-Cerrillo et al, 2020;Lara-Reyes et al, 2021;Lima et al, 2021;Lopes et al, 2021;Lusa et al, 2021).…”
