| onchocerca fasciata railliet and henry, 1910 and its nodule development in camels in saudi arabia. | a total of 192 male camels of three age groups (young, adult and old) from saudi arabia were examined for onchocerca fasciata infection by detection of microfilariae in skin snips and nodules in the nuchal ligaments and subcutaneous tissues of the neck and shoulder. the overall prevalence rates were 10.9 and 33.3%, respectively. the prevalence rate by the skin snip technique and the number of microfilariae per gram of skin were higher in young and adult camels than in old camels. however, the pr ... | 1991 | 1897120 |
| incidence and intensity of onchocerca fasciata railliet and henry, 1910 in local camels in saudi arabia. | onchocerca fasciata railliet & henry, 1910, which occurs in subcutaneous nodules, shows a site preference to the anterior parts of its host, camelus dromedarius l., i.e. the nuchal ligaments, neck, and shoulders. although the incidence of infection was generally high (59%), the infected camels did not exhibit any apparent disease. the intensity of infection ranged between 2 and 29, with a mean of 10.8 nodules per infected host. | 1986 | 3706990 |
| onchocerciasis in camels (camelus dromedarius) in saudi arabia. | during a survey in 1980-81, 125 of 478 (26.2%) camels in saudi arabia were found infected with onchocerciasis. the prevalence rates in local and imported camels were 93/272 (34.2%) and 32/206 (15.5%), respectively. the disease was characterized by hard nodules in the connective tissue around the nuchal ligaments and in the subcutis. the nodules consisted of cavities containing live, degenerate or dead onchocerca fasciata, inflammatory cells, fibrosis and calcification. the microfilariae were con ... | 1984 | 6520373 |
| [redescription of onchocerca fasciata r. and h., 1910, a parasite of the dromedary (author's transl)]. | onchocerca fasciata r. and h., 1910, a parasite of the dromedary is redescribed for material collected at abha, saudia arabia. this onchocerca, which is the only representative of the genus in camelids, is by its primitive morphology closest to species parasitic in equids (o. reticulata, o. cervicalis and o. raillieti). | 1981 | 7325527 |
| evidence of onchocerca fasciata (filarioidea: onchocercidae) in camels (camelus dromedarius): i-prevalence, nodular lesions appearance and parasite morphology. | examination of 3376 imported and 200 local egyptian camels was carried out during the period extending between september 1997 and august, 1998. these animals were carefully examined for the presence of onchocerca fasciata nodules and subsequently for o. fasciata adult parasites. results of this study revealed that imported camels had the higher infection rate (2.75%), while those of local origin showed no palpable or detected onchocerca nodules. distribution of these nodules was mainly on the tw ... | 2000 | 10714469 |
| the nematode parasite onchocerca volvulus generates the transforming growth factor-beta (tgf-beta). | transforming growth factor-beta (tgf-beta) is a highly conserved cytokine that has a well-known regulatory role in immunity, but also in organ development of most animal species including helminths. homologous tgf-b genes and mrna have been detected in the filaria brugia malayi. the in situ protein expression is unknown for filariae. therefore, we examined several filariae for the expression and localization of latent (stable) tgf-beta in adult and larval stages. a specific goat anti-human laten ... | 2009 | 19452170 |
| onchocerca fasciata: histochemical demonstration of succinate and nadh dehydrogenase. | the activities of selected enzymes of the respiratory chain system in onchocerca fasciata (filarioidea: onchocercidae) have been investigated histochemically. thus, the localization and distributions of nadh dehydrogenase (ec 1.6.99.3), succinate dehydrogenase (sdh) (ec 1.3.99.1) and cytochrome oxidase (ec 1.9.3.1) were investigated in various tissues of the adult female worm by employing mtt, nitro bt (dehydrogenases) and dab (cytochrome oxidase). different tissues varied considerably in their ... | 1996 | 8960199 |
| onchocerca fasciata: enzyme histochemistry and tissue distribution of various dehydrogenases in the adult female worm. | histochemistry studies of key dehydrogenases in the glycolytic pathway and related enzymes and the tricarboxylic acid (tca)-cycle enzymes were carried out on adult female onchocerca fasciata. the distribution pattern and enzymatic activities of 6-phosphogluconate dehydrogenase (6-gpdh), lactate dehydrogenase (ldh), mitochondrial glycerol-3-phosphate dehydrogenase (gpdh), nicotinamide adenine dinucleotide (phosphate) [nad+(p)]-linked isocitrate dehydrogenase (icdh), and nad+(p)-linked malate dehy ... | 1996 | 8825442 |
| histochemical localization of key glycolytic and related enzymes in adult onchocerca fasciata. | the activities of some key enzymes of the glycolytic and pentose phosphate pathways were investigated histochemically in adult female onchocerca fasciata (nematoda: filarioidea). the distribution patterns of phosphofructokinase (pfk), aldolase (ald), glyceraldehyde 3-phosphate dehydrogenase (g3pdh) and glucose 6-phosphate dehydrogenase (g6pdh) in different tissues of the worm were determined by employing nitroblue tetrazolium (nbt). the glycolytic enzymes pfk, ald, and g3pdh were distributed thr ... | 1994 | 7706683 |
| histochemical distribution of hydrolytic enzymes in adult onchocerca fasciata (filarioidea: onchocercidae). | histochemical techniques were employed to study the tissue distribution of hydrolytic enzymes in adult female onchocerca fasciata (filarioidea: onchocercidae). different tissues differed considerably in the localization and distribution of the six enzymes studied. acid phosphatase (acpase) activity was detected in the cuticle, hypodermis and reproductive organs. alkaline phosphatase (alkpase) activity was largely absent. adenosine triphosphatase (atpase) was found in the somatic musculature and ... | 1994 | 8036235 |
