This study aims to know the species blood-sucking flies, relative abundance, frequency, dominance their co...

The greenhead horse fly, Tabanus nigrovittatus Macquart, is frequently found in coastal marshes of the Eastern United States. The greenhead horse fly larvae are top predators in the marsh and thus vulnerable to changes in the environment, and the adults potentially are attracted to polarized surfaces like oil. Therefore, horse fly populations could serve as bioindicators of marsh health and tox...

Due to poor diagnostic facilities and a lack of medical alertness, allergy to Vespa wasps may be underestimated. Few allergens have been identified from Vespa wasps.Possible native allergen proteins were purified from the wasp venoms (WV) (Vespa magnifica Smith) by gel filtration, ion exchange chromatography, respectively. Their sequences were determined by Edman degradation and cDNA cloning. T...

Light microscopy revealed cuticular plaques restricted to the abdomens of both sexes of four species of brachycerous flies: Tabanus nigrovittatus Macquart, Apiocera barri Cazier, Hydrophorus viridiflos (Walker), and Dolichopus consanguineus (Wheeler). Using SEM, these plaques proved glabrous and unsculptured. Only at high magnification did they show small pits. TEM of the plaques showed the cut...

Horseflies are economically important blood-feeding arthropods and also a nuisance for humans and vectors for filariasis. They rely heavily on the pharmacological properties of their saliva to get a blood meal and suppress immune reactions of hosts. Little information is available on antihemostatic substances in horsefly salivary glands; especially no horsefly immune suppressants have been repo...

Mechanical transmission ofAnaplasma marginale by horse flies (Tabanidae) is thought to be epidemiologically significant in some areas of the United States. We compared the relative efficiencies of mechanical transmission of Anaplasma marginale by the horse fly, Tabanus fuscicostatus Hine, during acute infection (approximately 10(7) to approximately 10(9) infected erythrocytes [IE]/ml blood) wit...

Here, we report an outbreak of Trypanosoma vivax-induced trypanosomosis in Brazilian hair sheep on a farm in Paraíba state, a non-endemic region in northeastern Brazilian. Of 306 total sheep, 240 showed clinical signs and 216 died. Clinical signs included anorexia, lethargy, anemia, rough hair coat, weight loss, submandibular edema, abortion, and in some cases, neurological signs such as head p...

The present study was designed to asses specific IgE towards environment allergens in 42 healthy horses. Determination of this immunoglobulin in serum serve as diagnostic tools in allergic diseases to improve efficacy of the treatment and proper allergen selection to specific immunotherapy. Serum levels of allergen specific IgE were measured with equine monoclonal antibody, using 15 individual ...
