The 23-kDa piroplasm membrane protein of Theileria orientalis (p23) is an immunogenic protein expressed during the intraerythrocytic stage of the parasite; its function, however, remains unclear. To evaluate the host factor or factors that interact with p23, we examined the binding of p23 to components of the host cell surface. Recombinant p23 protein of the Ikeda genotype failed to bind to bov...

Alkaloid profiles of two Lupinus species growing naturally in Egypt (L. albus albus [synonym L. termis], L. varius orientalis) in addition to two New World species (L. hartwegii, L. densiflorus) which were cultivated in Egypt were studied by capillary GLC and GLC-mass spectrometry with respect to quinolizidine alkaloids. Altogether 44 quinolizidine, bipiperidyl and proto-indole alkaloids were i...

In the Bateson-Dobzhansky-Muller model of genetic incompatibilities post-zygotic gene-flow barriers arise by fixation of novel alleles at interacting loci in separated populations. Many such incompatibilities are polymorphic in plants, implying an important role for genetic drift or balancing selection in their origin and evolution. Here we show that NPR1 and RPP5 loci cause a genetic incompati...

Abstraet--Sclerotized oothecae from four species of cockroaches, Periplaneta americana, P. fuliginosa, Blatta orientalis and Blattella germanica, were examined by solid-state 13C-nuclear magnetic resonance and chemical analyses. The oothecae were composed of protein, water, calcium oxalate, diphenolic compounds, lipid, and uric acid. Calcium oxalate was the major soluble component in egg cases ...

Fatty acid profile of deep-sea mud shrimp (Solenocera hextii) and shovel-nosed lobsters (Thenus unimaculatus) harvested from south-west coast (Arabian Sea) India were evaluated compared. Palmitic oleic acids the principle saturated fatty monounsaturated acids, respectively in lobster species. T. unimaculatus contained greater concentrations C20-22 n-3 polyunsaturated such as docosahexaenoic eic...

Second-generation bioethanol production from sweet sorghum bagasse first extruded at different conditions and then treated with cell wall degrading enzymes and fermented with I. orientalis was determined. The twin extruder parameters tested were barrel temperature, screws speed, and feedstock moisture content using surface response methodology. The best extrusion conditions were 100°C, 200 rpm,...

The present study deals with the antibacterial activity of B. orientalis haemolymph against five bacterial strains namely, Pseudomonas aeruginosa, Proteus mirabilis, Staphylococcus aureus, Escherichia coli and Salmonella typhi. The results of the present study showed the maximum zone of inhibition against Escherichia coli, moderate effects were observed in Pseudomonas aeruginosa, Staphylococcus...

Aim The objective of this study was to examine the carrier status of theileriosis among apparently healthy cross-bred jersey cattle population of Odisha using conventional blood smear examination and polymerase chain reaction (PCR). Materials and Methods A total of 34 apparently healthy cross-bred Jersey lactating cows were considered in this study. Blood samples were subjected to microscopic...

During a year from 1999 to 2000, a total of 247 blood samples were collected from 214 cattle and 33 water buffaloes in 16 distinct geographical locations of Thailand and analyzed by allele-specific PCR amplification of major piroplasm surface protein (MPSP) genes of benign Theileria parasites. Four allelic MPSP gene types were determined namely C-type, I-type, B-type and Thai-type, which were o...

Many Koreans usually eat raw pond smelts, Hypomesus olidus, in the winter. This study was performed to evaluate the infection status with trematode metacercariae in pond smelts from January 1998 through February 1999. Among 1,305 fish collected, 459 were purchased from wholesale dealers in Chinchon-gun, Chungchongbuk-do, and the rest of them were caught with a casting net in Soyangho (Lake), Ta...
