Enzootic channels of the Canine parvovirosis in the Canton Guaranda, Bolivar Province, Ecuador

The objective was to know the behavior of the canine Parvovirosis (PVC) in mongrel dogs infected naturally by variants of PVC; for that reason, 2814 mongrel canines were used, beginning from retrospective data obtained among the years 2007-2010 in the Veterinary Hospital "Canine and Felines" of the city of Guaranda, Bolivar Province, Ecuador. The diagnosis of the illness was carried out by means of the application of the functional invariant of the clinical method and the use of the quick test Anigen (BIONOTE, seagu-dong Hwaseong-if, Gyeonggi-do, Korea). It was determined the occurrence of positive cases and the incidence of the PVC during the mentioned period, according to the procedures described by Thrusfield. The enzootic channels were built or of habitual behavior of the illness for the territory in the year 2011, starting from the series of time obtained among the years 2007-2010, by means of the method of the average of geometric mean of the rates of incidence, with the use of the program EPIDAT 3.1. To conclude, that the main epidemic indexes of the PVC will have the same behavior for the year 2011 and they can be modeled and predicted with high level of precision, whenever these can be expressed like a series of time.
