Pesquisa de parásitos gastrointestinales en pequeñas explotaciones ovinas del municipio de Toca, Colombia
Provedor de dados: 101
Autores: Pulido-Medellín,Martín O; García-Corredor,Diego; Díaz-Anaya,Adriana; Andrade-Becerra,Roy.
Con el objetivo de identificar los principales huevos y quistes de parásitos gastrointestinales presentes en las muestras de materia fecal tomadas en diferentes explotaciones ovinas del municipio de Toca Boyacá, se colectaron 90 muestras de materia fecal extraídas directamente del recto de ovinos de raza criolla, con el fin de identificar microscópicamente huevos y quistes de parásitos gastrointestinales. Los animales muestreados pertenecían a unidades familiares agropecuarias que no superaban los 20 animales. Las muestras se procesaron por la técnica de Ritchie modificada; el tipo de estudio aplicado fue de corte transversal simple y se realizó un análisis descriptivo para determinar la prevalencia en porcentaje de cada uno de los parásitos. El total de...

The accuracy of the FAMACHA© method was evaluated on the identification of female sheep fed two levels of crude protein, naturally infected with Haemonchus contortus, by means of the correspondent hematocrit value. Forty-seven female sheep of the breeds Santa Inês (n = 16), Texel (n = 16) and Ile de France (n = 15) aged between eight and twelve months were assigned to two treatments, 12 or 16 % crude protein in the diet. All the animals were wormed thirty days before the first data collections, which were done fortnightly between July 2005 and March 2006. The color of the ocular conjunctiva was individually evaluated according to the precepts of the FAMACHA© method and the hematocrit value of each animal was obtained in laboratory. A correlation of...

Moderate pathogenic effect of Ligophorus uruguayense (Monogenoidea, Ancyrocephalidae) in juvenile mullet Mugil liza (Actinopterygii, Mugilidae) from Brazil
Provedor de dados: 42

ABSTRACT Monogenoidea pathogenic activity can elicit various histological responses in fish. Species of Ligophorus are specific parasites of mullets, and its relationship with host fish may result in a moderate pathogenic action. In order to ascertain this relationship, estuarine mullets (Mugil liza) were collected in an estuary, reared in laboratory, for three weeks, and forwarded for histological and parasitological analyses. Ligophorus uruguayense (Monogenoidea) infestation in the gills of the mullets was identified. The severe infestation by only one species of Monogenoidea may result from the specificity of these parasites to mullets. Mullets submitted to histological analysis exhibited respiratory epithelium detachment; mild, moderate and severe...

Bovine demodicosis: a case report
Provedor de dados: 45
Autores: Lemos,L.S.; Santos,A.S.O.; Sales,L.G.; Silveira,L.S.; Carvalho,E.C.Q.
Tissues samples collected at necropsy from a 9 year-old Holstein cow were fixed in buffered 10% formalin for histological examination. Macroscopic finding did not reveal typical nodular cutaneous lesions. Vulvar microscopic sections of cutaneous tegument showed mites (Demodex bovis), alone and grouped in hair follicles and sebaceous glands.
