La Pythiosis es causada por Pythium insidiosum, afecta la piel y el tracto gastrointestinal de especies
animales como caninos, equinos, bovinos, felinos y a humanos. El presente estudio plante\uf3 como objetivo
determinar los factores de riesgo asociados a casos compatibles con pythiosis gastrointestinal canina
tales como edad, raza, sexo, \ue9poca del a\uf1o en que ingresaron al laboratorio y la tasa de infecci\uf3n de la
enfermedad en el Servicio Diagn\uf3stico Anatomopatol\uf3gico del Hospital Veterinario "Dr. Humberto Ram\uedrez
Daza". Periodo Enero 2001 - Julio 2007. Se desarroll\uf3 una investigaci\uf3n documental, descriptiva con
dise\uf1o retrospectivo basado en el estudio de 46 casos de caninos con diagn\uf3stico anatomopatol\uf3gico
compatible con pythiosis gastrointestinal canina. Los resultados se analizaron con estad\uedstica descriptiva
a trav\ue9s de distribuci\uf3n de frecuencias con el paquete estad\uedstico SPSS 10.0 para Windows, asimismo, se
calcul\uf3 el Odds Ratio y la tasa de infecci\uf3n. Se obtuvo como resultado que los caninos se infectan
principalmente durante la \ue9poca de lluvia y presentan signos cl\uednicos entre los 7 a 10 meses postinfecci\uf3n,
con una mayor ocurrencia de la enfermedad en adultos j\uf3venes con edades comprendidas entre 1 y 2
a\uf1os sin mostrar predilecci\uf3n por sexo, igualmente, los caninos de raza fenot\uedpicamente pura y de talla
mediana a grande tienen m\ue1s probabilidades de padecer la enfermedad, lo que llev\uf3 a la conclusi\uf3n que
los casos compatibles con pythiosis gastrointestinal canina representan una enfermedad emergente que
presenta una alta tasa de infecci\uf3n en el Servicio Diagn\uf3stico Anatomopatol\uf3gico del Decanato de Ciencias
Veterinarias de la UCLA.
ABSTRACT
Risk Factors Associated to Compatible Case with Canine Gastrointestinal Pythiosis
Pythiosis is caused by Pythium insidiosum, affects the skin and gastrointestinal tract of animal species
such as dogs, horses, cattle, cats and human. This study posed designed to determine the risk factors
associated to compatible cases with canine gastrointestinal pythiosis such as age, race, sex and time of
year that they entered at the laboratory and the infection rate of the disease in the pathological diagnosis of
the Hospital Service Veterinarian Dr. Humberto Ramirez Daza. Period January 2001 - July 2007. Was
developed a documentary research gift descriptive retrospective design based on a study of 46 cases of
dogs with canine gastrointestinal pythiosis diagnosis compatible. Descriptive statistics were used through
the distribution of frequencies with SPSS 10.0 for Windows also calculated the odds ratio and the rate of
infection. The result was that the canines are infected mainly during the rainy season and showing clinical
signs approximately 7 to 10 months postinfection, with an increased occurrence of disease in young adults
aged between 1 and 2 years without showing preference for sex, too, the phenotypically pure-bred dogs and
large-middle class are more likely to suffer from the disease, which led to the conclusion that the cases
compatible with canine gastrointestinal pythiosis represent an emerging disease that has a high rate of
infection in pathological diagnosis Service's Office of Veterinary Science at UCL
