Hump sore was found in 25% of 25, 000 cattle. The filariae were mainly confined to the superficial skin and once were found in blood from the ear vein. No rise of temperature nor systemic disturbance were noted. S. assamensis is viviparous. To transmit larvae from diseased cattle to unaffected ...

Examination of blood samples from 353 cows, 48 buffaloes, 172 goats, 12 dogs, 4 cats, a donkey and 69 ducks revealed microfilariae in 22 (6.2%) cows, one buffalo and one dog. The exact identity of the parasites was not established but those from cows were reported to be of Setaria and Onchocerca...

Of 8,000 flies caught while feeding on sores of zebu cattle in Bangladesh, 7,160 were Musca conducens. Of these, 2.02% were infected with Stephanofilaria assamensis, showing that M. conducens is the intermediate host.

Epizootiology, clinical picture, diagnosis, treatment using tincture of iodine and recommended prophylaxis of Stephanofilaria assamensis infections in zebu in Bangladesh are briefly discussed.

The author, seeking to elucidate the epidemiology of stephanofilariasis in zebu cattle in East Pakistan, examined monthly biopsy specimens from 111 zebu cattle with hump sore in 1969-70. The results are shown in two tables giving the monthely occurrence of eggs, and immature and adult forms of S....

An investigation was carried out to determine the biology and incidence of S. assamensis infection in zebu cattle in East Pakistan. Development occurs in the biting fly Musca conducens the larval stages developing in the intestine and then in the thoracic muscles of the insect. Infective forms...

A clinical and histological description is given of S. assamensis infection, which is often encountered in the lowlands of East Pakistan and commonly known as "hump sore". The incidence on some dairy farms is as high as 90-100%. The disease occurs during all seasons of the year, with the highest...

In Bangladesh, near Mymensingh, parasitic infections were found in 33.55% of 7,000 diseased cattle. Fascioliasis was found in 585 (8.35%), gastro-intestinal nematodes in 346 (4.94%) and other gastro-intestinal helminths (including Schistosoma sp.) in 115 (1.62%) and humpsore in 1.45%.
