RESUMO Durante o período de 2015 a 2021, foi avaliada a prevalência de endoparasitos em amostras fecais de cães provenientes do município de Niterói, RJ. As amostras foram analisadas no Laboratório de Apoio Diagnóstico em Doenças Parasitárias (LADDP) da Faculdade de Veterinária da Universidade Federal Fluminense (UFF), sendo usadas as técnicas de centrifugo-flutuação, sedimentação simples e mini-FLOTAC. Das 1.037 amostras analisadas, 30,6% (318/1.037) apresentaram resultados positivos para alguma infecção parasitária, sendo dessas 80,5% (256/318) positivas para apenas uma espécie de parasito e 19,5% (62/318) para infecções múltiplas. O parasitismo por Ancylostoma caninum foi o mais prevalente, com 39% (124/318), seguido por Giardia sp., 16% (51/318), Toxocara canis, 14,5% (46/318), Trichuris vulpis, 8,5% (27/318), Cystoisospora canis, 8,5% (27/318), Dipylidium caninum, 7,9% (25/318) e Cryptosporidium sp., 5,6% (18/318). O diagnóstico parasitológico de cães em áreas urbanas é a melhor alternativa para a avaliação da eficácia dos programas de controle de infecções parasitárias, incluindo aquelas com importância zoonótica. 201 2021 Niterói RJ LADDP (LADDP UFF, UFF , (UFF) centrifugoflutuação, centrifugoflutuação centrifugo flutuação, flutuação centrifugo-flutuação miniFLOTAC. miniFLOTAC mini FLOTAC.

ABSTRACT From 2015 to 2021 the prevalence of parasites was evaluated in fecal samples of dogs from the municipality of Niterói, RJ. The samples were examined at the Laboratory of Diagnostic Support in Parasitic Diseases (LADDP) of the Veterinary School at the Federal Fluminense University (UFF), using centrifugal flotation, sedimentation and mini-FLOTAC techniques. Of the 1,037 samples examined, 30.6% (318/1,037) showed positive results for some parasitic infections, of which 80.5% (256/318) were positive for only one species of parasite and 19.5% (62/318) for multiple infections. Parasitism by Ancylostoma caninum was the most prevalent, with 39% (124/318), followed by Giardia sp., 16% (51/318); Toxocara canis, 14.5% (46/318); Trichuris vulpis, 8.5% (27/318); Cystoisospora canis, 8.5% (27/318); Dipylidium caninum, 7.9% (25/318); and Cryptosporidium sp., 5.6% (18/318). The parasitological diagnosis of dogs in urban areas is the best choice to evaluate the efficacy of control measures adopted for parasitic infections, including those with zoonotic importance. 201 202 Niterói RJ LADDP (LADDP UFF, UFF , (UFF) flotation miniFLOTAC mini FLOTAC techniques 1037 1 037 1,03 306 30 6 30.6 318/1,037 3181037 318 (318/1,037 infections 805 80 5 80.5 256/318 256318 256 (256/318 195 19 19.5 62/318 62318 62 (62/318 prevalent 39 124/318, 124318 124/318 124 (124/318) sp sp. 16 51/318 51318 51 (51/318) canis 145 14 14.5 46/318 46318 46 (46/318) vulpis 85 8 8.5 27/318 27318 27 (27/318) 79 7 9 7.9 25/318 25318 25 (25/318) 56 5.6 18/318. 18318 18/318 . 18 (18/318) importance 20 (UFF 103 03 1,0 3 30. 318/1,03 318103 31 (318/1,03 80. 256/31 25631 (256/31 19. 62/31 6231 (62/31 12431 124/31 12 (124/318 51/31 5131 (51/318 14. 46/31 4631 4 (46/318 8. 27/31 2731 2 (27/318 7. 25/31 2531 (25/318 5. 1831 18/31 (18/318 10 0 1, 318/1,0 31810 (318/1,0 256/3 2563 (256/3 62/3 623 (62/3 1243 124/3 (124/31 51/3 513 (51/31 46/3 463 (46/31 27/3 273 (27/31 25/3 253 (25/31 183 18/3 (18/31 318/1, 3181 (318/1, 256/ (256/ 62/ (62/ 124/ (124/3 51/ (51/3 46/ (46/3 27/ (27/3 25/ (25/3 18/ (18/3 318/1 (318/1 (256 (62 (124/ (51/ (46/ (27/ (25/ (18/ 318/ (318/ (25 (6 (124 (51 (46 (27 (18 (318 (2 ( (12 (5 (4 (1 (31 (3
