With the purpose of verify the presence of larvae from the genus Gasterophilus in the Rio Grande do Sul State, a study was undertaken using 395 horses taken to slaughter in the city of Pelotas. The material analysis revealed that 126 animals (31,90%) presented infection, with 100 animals (25,32%) infected by Gasterophilus nasalis, and 47 animals (11,90%) infected by G. intestinalis. These resul...

myiasis is the infection caused by a variety of dipterous (fly) larvae in vertebrate’s tissue (man and domestic or wild animals). species of gasterophilus are obligate parasite of horses, donkeys, zebras, elephants and rhinoceroses. there are records worldwide, but mostly, in tropical and subtropical regions. this case report describes a type of gastric myiasis caused by g. intestinalis in an o...

We investigated infections with Gasterophilus spp. in three equids within the Kalamaili Nature Reserve (northern China). We conducted necropsies on 6 Przewalski's horses (Equus ferus przewalskii) and 6 Mongolian wild asses (Equus hemionus) and administered ivermectin to 10 overwintering domestic horses to expel parasites during winter periods. All 22 equids studied (100%) were infested with Gas...

Antennae are among the most elaborate sensory organs in adult flies, and they provide rich information for phylogenic studies. The antennae of five out of eight species of Gasterophilus Leach (G. haemorrhoidalis (Linnaeus), G. intestinalis (De Geer), G. nasalis (Linnaeus), G. nigricornis (Loew) and G. pecorum (Fabricius)), were examined using scanning electron microscopy. The general morphology...

In 2006, 725 horses aged 8 months to 16 years from different farms from the southern-eastern part of Poland were examined post-mortem for the presence of botfly larvae. One hundred and four horses (14.75%) demonstrated the presence of botfly larvae. An average infection rate was 52 larvae but low rate dominated. The larvae found belonged to Gasterophilus intestinalis and Gasterophilus nasalis. ...

Gasterophilosis is a myiasis related with gastric ulcers in equids and even colics. A serological survey to assess the presence of IgG antibodies against Gasterophilus spp. in horses from an oceanic climate area was conducted. A total of 672 blood samples were analyzed by an enzyme-linked immunosorbent assay (ELISA) and excretory/secretory antigens from G. intestinalis second-instar larvae. Res...

The arthropod parasite burdens of 14 Cape mountain zebra (Equus zebra zebra), shot for survey purposes in the Mountain Zebra National Park in the eastern Cape Province, were determined. Three species of Gasterophilus larvae and 9 ixodid tick species were recovered. Larvae of Gasterophilus pecorum were the most numerous of the fly larvae recovered and Margaropus winthemi was the most abundant ti...
