OBJECTIVES To determine the prevalence of Mutans Streptococci (MS) in children and to evaluate the relationship between the salivary levels of MS in children and their parents. MATERIAL AND METHODS 100 children aged 3-6 years along with their parents (100 mothers and fathers each) were included in the study. The children were segregated depending upon their age and level of caries experience....

Piroplasmosis is a serious debilitating and sometimes fatal disease. Phylogenetic relationships within piroplasmida are complex and remain unclear. We compared the intron-exon structure and DNA sequences of the RPS8 gene from Babesia and Theileria spp. isolates in China. Similar to 18S rDNA, the 40S ribosomal protein S8 gene, RPS8, including both coding and non-coding regions is a useful and no...

Hyalomma anatolicum anatolicum nymphs were collected from two localities in the Sudan: Eddamer in Northern Sudan and Wad-Medani in Central Sudan. They were allowed to moult to adult ticks, which were assessed for Theileria infection in their salivary glands using Feulgen stain. At Eddamer, 49.6% of 123 ticks examined were infected with Theileria and the mean intensity of infection was 1.3 (i.e....

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 ...

A PCR-based survey of hemoprotozoa parasites detected Babesia bigemina, Theileria orientalis and Trypanosoma theileri among cattle and water buffalo in Vietnam, and a new Babesia sp. closely related to Babesia ovata was detected in cattle only. In addition, Theileria annulata and Trypanosoma evansi were not detected in both cattle and water buffalo. Phylogenetic analysis detected T. orientalis ...

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...

PURPOSE Streptococcus mutans has been implicated as the major causative agent of dental caries. Although restorative treatment for caries is thought to temporarily eliminate the carious challenge, there are few reports of alterations in salivary mutans streptococci (MS) numbers and no reports of changes in salivary IgA antibody to S. mutans following restorative treatment. METHODS This study ...

We tried to develop an experimental system for quantifying piroplasm transmission in Theileria sergenti infection using a SCID mouse model, of which red blood cells (RBC) had been substituted with bovine (Bo). A mouse hybridoma cell producing antibody against Holstein RBC was established for distinguishing Holstein RBC from Japanese Black RBC by a immuno-staining method. T. sergenti piroplasms ...
