Nineteen species of anopheline and culicine mosquitoes are reported from larval collections made in northern Jordan and the Jordan Valley. Culex judaicus, Culiseta annulata, and Uranotaenia unguiculata are reported as new records for Jordan. The impact of agricultural development and man-made changes on the mosquito fauna of Jordan is discussed.

in order to compare pcr technique with smear method to find out theileria annulata in the cows carrier,cattle over one year was referred to the slaughter, samples were taken randomly since february 88 till may 89. we took blood from ear vein, then fixed with methanol & colored with gimsa at least we sarched for parasits under objective lenses (100x). also for pcr,we took 9ml blood from jagular ...

* E-mail: [email protected] ABSTRACT This study was carried out on 68 naturally infected buffaloes with Theileria annulata, in addition to 25 parasite-free buffaloes, distributed in small herds at Dakahlia and Gharbya governorates, Egypt, to demonstrate the clinical picture associated with theileriosis, with particular emphasis on the oxidative stress and ketosis relationship. The clinical...

Single dilution ELISAs were standardised for the determination of antibody titres against Theileria annulata using three antigens namely soluble piroplasm, cellular schizont or soluble schizont antigens. Antibody titres of 20 cattle serum samples of known identity were determined by multi-dilution ELISA using the three antigens. The ratio of the optical density (OD) of known positive and known ...

A reverse line blot (RLB) assay was developed for the identification of cattle carrying different species of Theileria and Babesia simultaneously. We included Theileria annulata, T. parva, T. mutans, T. taurotragi, and T. velifera in the assay, as well as parasites belonging to the T. sergenti-T. buffeli-T. orientalis group. The Babesia species included were Babesia bovis, B. bigemina, and B. d...

Mixed-genotype infections occur frequently in natural populations. Parasite genotypes are expected to interact within a host: competing for shared nutrients and being affected by the host's immune response to each other. Theoretically, competing parasites can be expected to exhibit increased rates of replication. Here, we investigate whether interactions between clones of Theileria annulata, a ...

Live attenuated vaccines are used to combat tropical theileriosis in North Africa, the Middle East, India, and China. The attenuation process is empirical and occurs only after many months, sometimes years, of in vitro culture of virulent clinical isolates. During this extensive culturing, attenuated lines lose their vaccine potential. To circumvent this we engineered the rapid ablation of the ...

AIM This study aims to develop and to standardize a polymerase chain reaction (PCR) assay that will diagnose clinical as well as carrier state of the disease and to compare the results with conventional microscopy technique. MATERIALS AND METHODS A herd of crossbred cattle with the previous history of theileriosis in village Lahli, district Rohtak, Haryana, was selected for this study. A tota...

Infection of bovine leukocytes by the apicomplexan parasite Theileria annulata results in alteration of host cell gene expression and stimulation of host cell proliferation. At present, the parasite-derived factors involved in these processes are unknown. Recently, we described the characterisation of a parasite gene (TashAT2), whose polypeptide product bears AT hook DNA-binding motifs and may ...
