| preliminary observations on helminth parasite populations of the dromedary in northern mali. | an abattoir survey on gastrointestinal parasites of the dromedary (camelus dromedarius) was carried out in march/april 1987 in northern mali. parasitological examination of the digestive tract contents of 11 dromedaries revealed that haemonchus longistipes was the predominant parasite with a prevalence as high as 85.7%. the genera impalaia, trichostrongylus, cooperia, and oesophagostomum were also recovered, but with a lower level of infection and frequency. the larval stage of the canine cestod ... | 1992 | 1466143 |
| [haemonchosis in camels]. | over the last thirty years, several surveys referring to the gastrointestinal parasites in the dromedary have shown high infestation rates by haemonchus longistipes. certain other studies have pointed out the economic and clinical importance of the camel haemonchosis. the author presents an overview of established knowledge on this major disease for the dromedary, which has hitherto been underestimated. the known features belonging either to this species or inferred from sheep haemonchosis, as a ... | 1989 | 2662272 |
| haemonchus longistipes railliet & henry, 1909 in goats in the sudan. | haemonchus longistipes specimens were collected from experimentally infected sudanese goats and camels for morphological studies. the specimens from goats were much smaller than those from camels, but their infectivity to camels was not affected by their passage in goats. goats inhabiting the same areas as camels in the sudan were found to be naturally infected with h. longistipes, but sheep were not and were resistant to experimental infection. | 1985 | 3989266 |
| the pathogenesis of experimental haemonchus longistipes infection in camels. | the pathogenesis and clinical signs of haemonchus longistipes infection were studied in four experimentally infected camels two of which were adults and the other two were young. in the former animals, an acute infection developed, characterized by mucoid diarrhoea, anorexia, anaemia, loss of body weight, oedema of the lower parts of the limbs, general malaise and death at 8-10 weeks post-infection. in the two younger camels, a less dramatic disease was encountered with less severe symptoms and ... | 1984 | 6538365 |
| experimental infection of sheep by the camel stomach worm, haemonchus longistipes. | an attempt has been made to infect sheep by haemonchus longistipes with the objective of developing a relatively cheap and manageable model of camel haemonchosis. a large proportion of inoculated animals (28/34) developed patent infections; the prepatent period was short, lasting for 3 to 4 weeks in the majority of infected animals. worm burdens were low and so was the total egg output. most of the recovered worms were reduced in size. | 1984 | 6541839 |
| the pathogenesis of experimental haemonchus longistipes infection in goats. | goats are highly susceptible to haemonchus longistipes and could therefore serve as an inexpensive model to study camel haemonchosis. the course of the disease in goats is similar to that in camels and to h. contortus infection in sheep and goats. unlike the age-dependency of camel haemonchosis, however, the severity of h. longistipes infection in goats is dose-dependent and varies from mild to hyperacute. | 1983 | 6643762 |
| the prevalence and pathogenesis of naturally-occurring haemonchus longistipes infection in sudanese camels. | camel haemonchosis is prevalent in the sudan, especially during the rainy season, with a decrease in prevalence in the dry season possibly due to delayed maturation of the worms. the naturally occurring disease in sudanese camels is characterized by emaciation, anaemia, oedema of the lower parts of the limbs, eosinophilia, hypoproteinaemia, hypoalbuminaemia, hyperglobulinaemia and eosinophilia, as well as elevated blood urea concentrations. | 1984 | 6736305 |
| establishment of camel isolates of haemonchus longistipes and trichostrongylus colubriformis in goats. | two main nematode parasites, haemonchus longistipes and trichostrongylus colubriformis, have been reported to cause morbidity and mortality in camels. although goats are usually reared with camels in the combined animal husbandry system prevailing in northern india, these parasites have not been reported in goats. therefore, it was planned to conduct an experimental cross-transmission study of h. longistipes and t. colubriformis isolated from camels and transferred to young goats. twelve healthy ... | 1993 | 8128589 |
| adaptation to arid environment: haemonchus longistipes in dromedaries of saharo-sahelian areas of mauritania. | the adaptations of the trichostrongylid nematode haemonchus longistipes of dromedaries (camelus dromedarius) to the harsh environment of saharo-sahelian climate were assessed by means of (i) an epidemiological survey of dromedary infection in the south-west of mauritania, (ii) an estimate over a 3 year period of parasite distribution within the host population and of prolificacy of h. longistipes females recovered from natural populations of infected dromedaries sampled at nouakchott's slaughter ... | 1996 | 9017882 |
| host range and the maintenance of haemonchus spp. in an adverse arid climate. | three haemonchus species (haemonchus contortus, haemonchus placei and haemonchus longistipes) live in sympatry in sahelian areas such as mauritania (west africa). four host species (dromedary, zebu cattle, sheep and goats) share the same pastures for several months per year. experimental infection by h. contortus or h. placei was achieved only poorly in dromedaries, and h. contortus or h. longistipes infection failed to establish in zebu cattle. conversely, h. placei and h. longistipes successfu ... | 1998 | 9512988 |
| efficacy of closantel plus albendazole liquid suspension against natural infection of gastrointestinal parasites in camels. | oral administration of closantel in a dose of 10 mg/kg plus albendazole in a dose of 5 mg/kg liquid suspension was studied in 75 camels naturally infected with various types of gastrointestinal parasites. the camels involved were 15 pregnant she-camels, 20 non-pregnant she-camels and 40 male camels of various ages. each camel received a single oral dose of closantel (10 mg/kg) plus albendazole (5 mg/kg) orally. two weeks later, 20 camels of this group were re-dosed again with the same dose of th ... | 1999 | 10321589 |
| epidemiological studies on gastrointestinal helminths of dromedary (camelus dromedarius) in semi-arid lands of eastern ethiopia. | a total of 752 dromedaries were examined and 75% were found to be harbouring nematode eggs. the mean epg was 1831 and the range was from 100 to 21,200. the prevalence rates in the four-age groups examined were 59.6% (3-7 years), 72.4% (8-12 years), 76.1% (13-17 years) and 83.9% (18-22 years). the prevalence rate for females and males were 77.6 and 64.8%, respectively and for long dry, short rainy, short dry and long rainy seasons were 66, 80, 69 and 82.6%, respectively. the mean epg of faeces wa ... | 2002 | 11900928 |
| value of haemonchus longistipes purified antigens in diagnosis of gastro-intestinal nematodes infection in camels. | fractionated haemonchus longistipes crude antigen revealed 7 protein fractions at molecular weights of 93, 74, 67, 56, 32, 26 and 16 kda. the bands at 56, 32 and 26 kda reacted specifically with h. longistipes hyperimmune sera prepared in rabbit (1:100 dilution) using eitb technique. the eluted concentrated fractions as well as crude worm antigens were used in diagnosis of natural infection of gastro-intestinal nematodes (gin) only or associated with other parasites in camels using elisa techniq ... | 2007 | 19069956 |
| thiosulphate: cyanide sulphur transferase activity in some species of helminth parasites. | investigation on the characteristic pattern of enzymes in various organisms may be of particular importance, as this type of information can help to understand certain physiological and biochemical processes in living organisms. thiosulfate: cyanide sulfurtransferase (rhodanese) is a ubiquitous multifunctional enzyme, which its major function is generally believed to be in cyanide detoxification. the present study was conducted to determine the activity of this enzyme in some parasitic helminths ... | 2014 | 24808648 |
| haemonchus longistipes railliet & henry, 1909 (nematoda, trichostrongylidae) from the egyptian dromedary, camelus dromedarius (artiodactyla: camelidae), first identification on the basis of light and ultrastructural data. | haemonchus longistipes is a gastrointestinal abomasal nematode which is one of the most prevalent and pathogenic parasites infesting the stomach of ruminants. on the basis of light and ultrastructural data, the objective of the present study was to introduce a first identification of the cameline haemonchosis caused by h. longistipes. abomasa of 42 egyptian camels camelus dromedarius (artiodactyla: camelidae) were collected monthly from september 2013 to april 2014 from the main slaughter house ... | 2014 | 25273629 |
