Background: Pulmonary tuberculosis (PTB) has recently become a major problem in developed countries especially in immune compromised HIV infected individuals. Cytokines, their genes and receptors have been implicated in the protective immunity, pathophysiology and development of tuberculosis.   Material & Methods: In the present study the genotype frequencies of a number of polymorphic genes co...

The Rhesus (Rh) blood group is the most polymorphic human blood group and it is clinically significant in transfusion medicine. Especially, D antigen is the most important and highly immunogenic antigen. Due to anti-D, it is the cause of the hemolytic disease of the newborn and transfusion reaction. About 0.1%-0.5% of Asian people are RhD-negative, whereas in the Thai population, the RhD-negati...

OBJECTIVE This case-control study was undertaken to evaluate the association of HLA-B51 antigen and its allelic types with Behçet's disease (BD) and with recurrent aphthous stomatitis (RAS), to investigate the degree of this association with diagnostic types and clinical variables of BD. METHODS The DNA typing of HLA-B51 by nested PCR-SSP was performed in 61 patients with BD, 56 patients with...

BACKGROUND: Entomological methods may provide important tools for monitoring the progress of lymphatic filariasis elimination programs. In this study, we compared dissection of the vector, Culex quinquefasciatus, with the polymerase chain reaction (PCR) to assess filarial infection levels in mosquitoes in the context of a lymphatic filariasis elimination program in Leogane, Haiti. METHODS: Mosq...

BACKGROUND The objective of this study was to investigate HLA-DRB1*and DQB1* allelic polymorphisms in Iranian patients with hydatidose. This is the first survey dealing with the correlation between HLA-DRB1* and DQB1* alleles and cystic echinococcosis in Iranian patients. METHODS The study was carried out on 56 patients with confirmed cystic echinococcosis and 30 apparently healthy individual...

Background and Objective: The outcome of hepatitis B virus (HBV) infection may be influenced by host factors like Human Leukocyte Antigen (HLA). We have investigated HLA-A and DRB1 alleles in patients with persistent hepatitis B infection compared to subjects who had spontaneously recovered from HBV infection. To complete the findings of this study we performed another survey in certain HLA all...

BACKGROUND Severe and potentially fatal hypersensitivity reactions to drugs, particularly antiepileptics, are clinically unpredictable. Recent evidence has revealed a strong and specific association between the implicated drug, the type of adverse reaction, and the particular HLA genotype. An urgent need exists for rapid diagnosis of HLA status to guide drug prescription; however, traditional H...

Several bacteria belonging to the family Pasteurellaceae might act as pathogens in rabbits. In particular, Pasteurella multocida is considered to be an important one and outbreaks caused by this species result in considerable economic losses. However, proper identification of P. multocida at the species and even more so at the subspecies level is often not very precise. Moreover, Pasteurellacea...
