Teat onchocercosis in cows with reference to prevalence, species involved and pathology

Galectins from Onchocerca ochengi and O. volvulus and their immune recognition by Wistar rats, Gudali zebu cattle and human hosts

“…Extraction of skin and uterine mff were done from O. ochengi infected cattle skin and O. ochengi adult female worms, respectively. This was done using the methods described by Beytut et al [ 62 ] for skin mff and that of Bianco et al [ 63 ] and Medina-De la Garza et al [ 64 ] for uterine mff with some modifications. Briefly, O. ochengi infected cattle skins (with palpable and visible nodules) around the umbilicus (udder/scrotum) were collected from the Ngaoundéré slaughter house from freshly slaughtered cattle.…”

“…The mixture was centrifuged for 30 min at 87 x g . After centrifugation, the preparation formed three phases with the mff accumulating in the middle phase, which was collected and washed four times in Pen/Strep (200 IU) PBS by centrifuging for 5 min at 87 x g [ 62 ].…”

Parasitic Aortitis due to Onchocerca armillata in Slaughtered Cattle in the Southeastern Region of Turkey

“…Alibasoglu et al [1] reported that onchocercosis was seen in the southeastern provinces of Turkey in cattle, was not seen in western Anatolia provinces, and it was concluded that the disease was seen in tropical climates. However, according to recent study conducted by Beytut et al [6] the parasite was also seen at Kars province where the climate is severely cold than that of southern regions, also some other cases reported from Greece [14] . This means that Onchocercosis can also be seen in cold places.…”

“…There is any report about parasitic aortitis caused by other Onchocerca species which is located around arcus aorta [1,8,10] . In this study, we decsribed parasitic aortitis due to Onchocerca armillata around arcus aorta In our country the prevalence and pathology of aortic onchocercosis have been only studied by Alibaşoğlu et al [1] and Beytut et al [6] . Alibaşoğlu et al [1] examined the aortas of animals around Cukurova and Western Anatolia regions and they seen intensive infestation in the Cukurova region.…”

“…Onchocerca armillata a parasite found in the wall of the aorta of cattle [1,2] buffalo [3] , sheep [3][4][5] , goat [6] and camels [7] . Onchocerca armillata is mostly observed in the south of the Asian regions and African continent closer to the equator [8][9][10] .…”
