description Enteroparasitosis in dogs constitutes a veterinary and public health challenge in rural Andean settings. This observational, cross-sectional and analytical study assessed infection prevalence, co-infection patterns, and associated factors in 105 owned dogs sampled door-to-door in Picup during January–February 2022. Fecal samples were examined using direct smear with saline/Lugol, Sheather’s flotation, spontaneous sedimentation, and modified Ziehl–Neelsen staining. The prevalence of at least one parasite was 65.7% (69/105; 95% CI: 56.2–74.1). The most frequently detected parasites were Ancylostoma spp. (47.6% overall; 72.5% among positives), Toxocara canis (16.2%), Trichuris vulpis (10.5%), Dipylidium caninum (7.6%) and Cystoisospora spp. (7.6%), while Cryptosporidium spp. was detected in 1.0%. Among positive dogs, monoparasitism predominated (68.1%), followed by biparasitism (26.1%) and triparasitism (5.8%). Male dogs showed a higher prevalence than females (PR = 1.60; 95% CI: 1.10-2.31; p = 0.013), and reported external deworming was associated with higher prevalence of infection (PR = 1.39; 95% CI: 1.01-1.90; p = 0.042). No associations were found with age, street access, cohabitation with other species, dog function, diet type, number of dogs per household, previous endoparasitic infection, or internal deworming (all p > 0.05). In the multivariable analysis, male dogs (aPR = 1.70; 95% CI: 1.20-2.41; p = 0.003) and external deworming (aPR = 1.56; 95% CI: 1.16-2.08; p = 0.003) were associated with a higher prevalence of enteroparasites, while vaccination showed a protective effect (aPR = 0.70; 95% CI: 0.54-0.91; p = 0.008). These findings indicate a high prevalence of intestinal parasites, dominated by hookworms, and highlight the need to implement One Health strategies.

La enteroparasitosis en perros constituye un desafío veterinario y sanitario en contextos rurales andinos; este estudio observacional, transversal y analítico estimó la prevalencia de infección, describió patrones de coinfección e identificó factores asociados en 105 perros con propietario muestreados puerta a puerta en Picup durante enero-febrero de 2022. Las heces se evaluaron mediante frotis directo con solución salina/Lugol, flotación con solución de Sheather, sedimentación espontánea y tinción de Ziehl–Neelsen modificada. La prevalencia de ≥1 parásito fue 65,7% (69/105; IC95%: 56,2-74,1). Las detecciones más comunes fueron Ancylostoma spp. (47,6% del total; 72,5% entre positivos), Toxocara canis (16,2%), Trichuris vulpis (10,5%), Dipylidium caninum (7,6%) y Cystoisospora spp. (7,6%); Cryptosporidium spp. se observó en 1,0%. Entre los positivos predominó el monoparasitismo (68,1%), seguido de biparasitismo (26,1%) y triparasitismo (5,8%). Los perros machos presentaron mayor prevalencia que hembras (RP = 1,60; IC95%: 1,10-2,31; p = 0,013) y la desparasitación externa reportada se asoció con mayor positividad (RP = 1,39; IC95%: 1,01-1,90; p = 0,042). No se hallaron asociaciones con edad, acceso a la calle, convivencia con otras especies, rol del can, tipo de alimento, número de perros por vivienda, antecedente de endoparasitosis ni desparasitación interna (todas p>0,05). En el análisis multivariable, los perros machos (RPa = 1,70; IC95%: 1,20-2,41; p = 0,003) y la desparasitación externa (RPa = 1,56; IC95%: 1,16-2,08; p = 0,003) se asociaron con mayor prevalencia de enteroparásitos, mientras que la vacunación mostró un efecto protector (RPa = 0,70; IC95%: 0,54-0,91; p = 0,008). Se concluye que la prevalencia de parásitos intestinales es elevada y dominada por ancilostomídeos, con implicancias para acciones de Una Salud.
