Última A review on the diagnosis infection in cattle of Schistosoma bovis: current status and future prospects Ciência Rural Aradaib,Imadeldin Elamin; Ahdelmageed,Elabbas Mohamed; Hassan,Sanaa Ali; Riemann,Hans Peter. Bovine schistosomiasis, caused by Schistosoma bovis, is a serious veterinary problem in many parts of the worid. The current methods used for the diagnosis of the disease include clinical signs, pathological lesions, parasitological and serological techniques. As clinical signs and parasitological lesions caused by S. bovis are indistinguishable from those induced by other trematode parasites, confirmation of diagnosis by these methods is unreliable. Parasitological techniques used to demonstrate eggs of the parasite in fecal or tissue samples represent the most accurate method for detection of an active S. bovis infection. The tissue of choice for detection of S. bovis infection is the liver because of the visible macroscopic lesion that can be seen in...

Ano: 1995 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-84781995000300029 ELISA FOR BOVINE SCHISTOSOMIASIS VACCINE EVALUATION: A PRELIMINARY REPORT Ciência Rural Aradaib,Imadeldin Elamin; Abbas,Babiker; Osburn,Bennie; Bushara,Hamid Omer; Taylor,Martin. Six calves were immunized with schistosomula of Schistosoma bovis irradiated at 3 or 20 Kilorad (Krad) and three calves were kept as controls. Twenty four weeks post immunization, three calves (one from the 20 Krad and two from the 3 Krad group) were challenged with normal cercaria of S. bovis. The immune response was monitored by agar gel immunodiffusion (AGID) and the Enzyme Linked Immunosorbent Assay (ELISA) using adult worm antigen. Using AGID, precipitin lines were observed only with sera from challenged animals. Using ELISA, the immune response of the vaccinated calves was first detected by 2-3 weeks, peaking by 6-8 weeks post vaccination. The immune response of the three challenged calves was elevated by 2 weeks post challenge, peaking at 8-10 weeks...

Ano: 1994 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-84781994000300020 Experimental bovine schistosomiasis in zebu calves Ciência Rural Aradaib,Imadeldin Elamin; Abbas,Babiker; Riemann,Hans Peter; Osburn,Bennie Irve. Five calves were each experimentally infected with 30,000 cercariae of Schistosoma bovis and three calves were kept as controls. S. bovis eggs first appeared in feces of the infected animals by week 5 post infection and all animals were shedding by week 6 post infection. Between week 7 and 9 post infection, where fecal egg counts were highest, the infected animals developed mucoid and then hemorrhagic diarrhoea and they became dull and depressed. Packed cell volumes and hemoglobin concentrations of the infected animals showed progressive reductions compared to the uninfected control calves. The animals were necropsied and perfused at week 12 post infection and tissue egg densities and worm burden were determined.
