Parasitismo gastrointestinal en cuyes (Cavia porcellus) de tres comunidades de Huancavelica, Perú
Revista Científica de la Facultad de Ciencias Veterinarias
Las parasitosis producidas por protozoarios y helmintos constituyen problemas sanitarios en la crianza productiva de cuyes (C) raza Perú; sin embargo, conocimientos relacionados a su etiología, dinámica de infección y epidemiología son limitados. Esto dificulta el diseño de programas de control óptimo y rentable. Se identificó la presencia de parásitos gastrointestinales en C de comunidades de Huando, Mariscal Cáceres y Yauli, Huancavelica-Perú, determinándose la fauna, frecuencia, carga parasitaria, grado de infección y su relación con procedencias y sexo. Se muestrearon 156 C entre ambos sexos, se recolectó 20 gramos (g) de heces por animal y se analizaron por técnicas coprológicas de flotación – sedimentación, Ziehl–Neelsen modificada y McMaster Modificado. La prevalencia de endoparásitos fue 82,5 %: siendo los protozoarios más frecuentes con 82,7 %, que los Nematodos, con 38,5 %. Eimeria caviae tuvo frecuencias de 85,7; 80,0 y 83,3 % en comunidades de Huando, Mariscal Cáceres y ...

The objective of the study was to estimate the prevalence of gastrointestinal helminthiasis in guinea pigs of family production-commercial district of Matahuasi, Concepción province, Junín. Also, determine the genera and / or species of gastrointestinal helminths; load and type of parasitism (monoparasitism, biparasitism or poliparasitism), degree of agreement between the differential count of parasites to post mortem examination vs coprological techniques and the sensitivity / specificity of coprological techniques in the diagnosis of gastrointestinal helminthiasis in guinea pigs. 262 gastrointestinal tracts were acquired from guinea pig collection centers in the district of Matahuasi, under the family-commercial raising system, from January to March 2017. Each acquired gastrointestinal tract was immediately linked at strategic points in order to individually analyze the following organs: stomach, small intestine and large intestine, as well as fecal samples obtained from the rectum. Sample processing was performed by differential parasite count for post mortem examination and complementary coprological techniques (Flotation and modified Dennis) in the laboratory of Microbiology and Parasitology-Parasitology Section of the FMV-UNMSM. The collected helminths were subjected to alcohol-phenol clearance processes for their morphological identification and quantification of parasitic load. A high prevalence of gastrointestinal helminths of 82.8 ± 4.6% was found, where Paraspidodera uncinata, Capillaria spp., Trichostrongylus axei and Trichuris spp. with percentages of 74, 34, 6.1 and 3.4% respectively. The average number of helminths per animal was 24.7, where Paraspidodera uncinata, Capillaria spp., Trichostrongylus axi and Trichuris spp. showed averages of 23.5, 8.7, 1.2 and 1.2 respectively. Likewise, among parasitism types, monoparasitism (50.4%) was the most frequent, followed by biparasitism (30.2%). On the other hand, when evaluating the degree of concordance between the coprological techniques, he found Kappa (K) values equal to 0.19 and 0.13 indicating that he was of the poor type. Additionally, the sensitivity and specificity of the modified flotation and Dennis techniques were determined, with sensitivities (39.6, 29.5%) and specificities (89.9, 93.3%) respectively.
The parasitic fauna of 21 Chimango caracaras (Milvago c. chimango) from Chillán city (36° 34' S- 72° 06' W) was analyzed. Three species of Nematoda (prevalences between parentheses) are reported: Porrocaecum depressum (Ascarididae) (38.1 ± 10.6%), Cyrnea (Procyrnea) spinosa (Habronematidae) (52.4 ± 10.9%) and Capillaria tenuissima (Capillariidae) (71.4 ± 9.9%). No species of Trematoda, Cestoda, Protozoa or Trichinella were reported. No histologic injury atributed to gastrointestinal parasites was observed.
Aim: To Identify and to determine the frequency of gastrointestinal parasites in canines at the SAIS Tupaca Amaru community located in Canchayllo district, in Jauja, Junin-Peru. Methods: 97 fresh stool samples were collected and analyzed using four laboratory techniques: direct exam, concentration techniques through flotation and sedimentation, and Ziehl Neelsen stain. Results and conclusions: Total frequency of gastrointestinal parasites was 73,2 % (71/97). Seven species were identified: Toxocara (38 %), Toxascaris (14,1 %), Ancylostoma (16,9 %), Strongyloides (22,5 %), Taenia (1,4 %), Isospora (2,8 %), y Crypstosporidium (35,2 %). 70, 4 % of the samples contained a single parasite. Associations of two species were found in 28.2 % of samples. One sample (1,41 %) with the presence of three parasites was found. Additionally, males had higher presence of parasites (61,9%) than females (38,1%); likewise there was higher presence in adults (71,1%) than puppies (28,9%) and finally there were more parasites in canes fed with home diet (59,8%). The results provide information to justify the development of parasite control programs in this community. KEYWORDS: canines, parasites, zoonosis, toxocariasis

Agouti paca (Rodentia: Agoutidae) en cautiverio en el trópico mexicano Abstract: Previous reports showed that the tepezcuintle (Agouti paca) is commonly infested by gastrointestinal parasites (GIP), mainly Eucoccidiida and helminths. However, there is no available information on the frequency of those parasites and their faecal egg excretions at different moments during the year. These information would provide a valuable baseline for the establishment of control strategies against GIP in tepezcuintles under captivity. The objectives of the present study were to determine the prevalence of GIP orders and genera that infest tepezcuintles under captivity and, to describe the dynamics of faecal egg and oocyst excretion in a year. Ten tepezcuintles were sampled (faeces) twice every month for twelve months. The faecal samples were processed by the flotation and McMaster techniques. Two orders of parasites were determinated: Strongylida and Eucoccidiida. Two genera of nematodes were also determinated: Strongyloides and Trichuris. The prevalence of Strongylida eggs, Eucoccidiida oocysts and Trichuris sp. eggs reached 10-20 % of animals in certain months. The most important genus was Strongyloides, found in 60 to 100 % of the animals year round. The average excretion of eggs in the group was 45 to 372 eggs per gram. Tepezcuintles kept under captivity in Yucatan are parasited with Strongyloides sp throughout the year, but only occasionally had oocysts of Eucoccidiida and eggs of Strongylida and Trichuris sp.
