A Polymerase Chain Reaction (PCR) and Southern blot hybridization for the detection of Theileria annulata are described. The PCR used primers amplifying a 785 base-pair fragment of the T. annulata gene which encodes the 30 kDa major merozoite surface antigen, Tams1. The sensitivity of the PCR in bovine blood was 1 piroplasm in 1 microl of blood. T. buffeli,(More)
Spotted fever group (SFG) rickettsiae have recently been identified for the first time in UK ticks. This included the findings of Rickettsia helvetica in Ixodes ricinus and Rickettsia raoultii in Dermacentor reticulatus. This paper further investigates the occurrence of SFG rickettsiae in additional geographically distinct populations of D. reticulatus, and(More)
Streptococcus mutans Ingbritt was grown anaerobically in a chemostat with a glucose limitation, as well as with an excess of glucose (amino acid limitation) at dilution rates (D) between 0.05 and 0.4 h(-1) (mean generation time = 12 to 1.5 h). The glucose-limited culture produced cells having 1.5- to 6.0-fold greater glycolytic activity than the cells from(More)
BACKGROUND Leptin is a protein produced by adipose tissue that circulates to the brain and interacts with receptors in the hypothalamus to inhibit eating. In obese humans, serum leptin is up to four times higher than in lean subjects, indicating that human obesity is associated with a central resistance to the weight-lowering effects of leptin. Although the(More)
A comparison was made of the properties of Streptococcus mutans Ingbritt grown in continuous culture under conditions of excess glucose (nitrogen limitation) and limiting glucose at mean generation times of 1.7 to 14 h. Only low levels of glucoamylase-specific glycogen were formed in cells from either culture, and the total carbohydrate content of the cells(More)
Crimean-Congo haemorrhagic fever virus (CCHFV) is one of the most widespread of all medically important arboviruses with ticks of the Hyalomma spp. serving as the main vectors. Infection of livestock by CCHFV serves as a route of exposure to humans, as a reservoir of disease and as a route of importation. This study discusses the pathways and data(More)
We have constructed a genetic linkage map of human chromosome 16 based on 46 DNA markers that detect restriction fragment length polymorphisms. Segregation data were collected on a set of multigenerational families provided by the Centre d'Etude du Polymorphisme Humain, and maps were constructed using recently developed multipoint analysis techniques. The(More)
The localization of the autosomal dominant polycystic kidney disease locus (PKD1) within an array of anonymous polymorphic DNA sequences on chromosome 16 band p13 was determined by multipoint mapping. Nine polymorphic DNA markers, including two hypervariable sequences, were used to study 19 PKD1 and 21 reference families. PKD1 was found to lie proximal to(More)
The production of monoclonal antibodies to the bloodstages of the haemoprotozoan parasites Babesia caballi and Babesia equi and the characterization of their corresponding antigens are described. Species specific and immunogenic proteins of both parasites were identified using SDS-PAGE, Western blotting and ELISA. These proteins were then electroeluted from(More)
