filariasis in dogs is caused by several species of filariids. because of importance of this infection in veterinary medicine and public health, it is necessary to carry out an epidemiological and cross sectional studies in various geographical areas and use of well-adapted diagnosis methods. in this study 205 capillary and whole blood samples were collected from doges in various counties of eas...

The aim of this study was to determine the prevalence and distribution of canine dirofilariosis from different districts of the Mazovian Province in central-eastern Poland. 462 dogs aged from 1.5-14 years were examined for dirofilariosis. Blood samples were examined for the presence of microfilariae using the Knott method, as well as the method of Kingston and Morton, after centrifugation in ha...

In 2011-2013 1588 samples of dogs' blood were examined for dirofilariosis using Knott method, as well as the Kingston and Morton method. The species of microfilariae was determined on the basis of morphometric characteristics. Samples were also examined using the Canine Heartworm Antigen Test. Positive samples were examined using a multiplex PCR assay for species confirmation. Microfilariae bel...

Canine dirofilariasis caused by Dirofilaria immitis is usually diagnosed by specific antigen testing and/or identification of microfilariae. However, D. immitis and at least six other filariae can produce canine microfilaremias with negative heartworm antigen tests. Discriminating these can be of clinical importance. To resolve discordant diagnoses by two diagnostic laboratories in an antigen-n...

Between July and August 2009, a total of two hundred crossbreed dogs in three contiguous littoralprovinces of Guilan, Mazandaran and Golestan were sampled. Circulating antigens and/or microfilariae ofDirofilaria immitis were found in 25.5% of dogs in the whole studied area. The highest infection rate wasfound in Guilan (51.42%), followed by Golestan and Mazandaran provinces (15.38% and 7.69%, r...

A very high prevalence of microfilaremia of 42.68 per cent out of 164 canine blood samples examined was observed in Cherthala (of Alappuzha district of Kerala state), a known human Brugia malayi endemic area of south India. The species of canine microfilariae were identified as Dirofilaria repens, Brugia malayi, and Acanthocheilonema reconditum. D. repens was the most commonly detected species ...

A survey on the prevalence of canine heartworm was conducted in 1, 495 dogs from Maranhão Island, State of Maranhão, Northeastern Brazil, from 1991 to 1994, by testing for microfilariae in blood. Of the total, 1,358 (12.8% of which were infected) were dogs with no known history; they included 1,265 homeless animals (10.3% with microfilariae) and 93 kept by owners at the time the survey was cond...

Onchocerca lupi, a zoonotic nematode infecting the eyes of carnivores, has been increasingly reported in dogs from Europe and the USA. In order to improve the current status of knowledge on this neglected filarioid, diagnostic imaging tools (i.e., ultrasound scan, computed tomography and magnetic resonance imaging) are herein used to diagnose canine onchocercosis in two dogs, which scored posit...
