Blastocystis Sp: a Neglected Zoonotic Protozoan

خلاصه انگلیسی

The significance of Blastocystis as a cause of human and animal disease remains unknown. It has been suggested that the organism is zoonotic. This study was undertaken to determine the prevalence of Blastocystis sp in stray dogs, which may be implicated as a reservoir for human infection. During the period April-September 2007, 50 stray dogs were collected from different parts of urban Sari, in Mazandaran Province, Iran. They were immediately transported to Sari Medical School, where they were necropsied; the gastrointestinal tract was opened completely and searched for Blastocystis sp The specimens were examined by wet mount and formalin-ether concentration methods. Blastocystis sp were found by light microscopy in 14 (28%) of 50 fecal samples from the youngest (2 months) to the oldest (4 years) dogs in this study. Six of 21 male (28.6%) and 8 of 29 female (27.6%) dogs had Blastocystis sp in their fecal matter. No correlation between the presence of Blastocystis sp and the age or sex of the host was found in dogs studied. The high prevalence of the organism in dogs indicates that stray dogs may be an important source of Blastocystis sp infection for humans.
