background: in iran, despite the use of vaccine since 1976, we are still having local epidemics especially in the children aged 15-20 years old. since 1996, the yearly epidemics of measles have been reported in these groups in sistan- baluchestan province, south east of iran. the present study was conducted to determinate the level of immunity in this target population in zahedan. methods: a to...

【目的】ワクチン接種後の抗体価評価を行う事で、患者・健診受診者への情報提供及び、疫学的評価を目的とし検査を行った。プロゾーン現象を呈した臨床からの報告例は少なく、抗体測定における注意喚起を行う価値が高いと判断したため報告とした。

To investigate the markers useful for evaluating the long-term efficacy of interferon (IFN) therapy, the quantity of hepatitis C virus (HCV) RNA and two anti-HCV antibody titers (anti-N14 and anti-C-100-3 antibody) in 21 chronic hepatitis C patients were determined. In all complete responders, a sustained clearance of the virus and reductions in the anti-HCV antibody titers were observed during...

Oral bacteria cause infective endocarditis (IE), so severe periodontitis is thought to be high risk for IE. We suggest the identification of high-risk patients by an IgG antibody titer test against periodontal bacteria might become common screening test.

There are no contemporary data available describing human immunity to novel influenza A/H7N9. Using 1723 prospectively collected serum samples in southern Vietnam, we tested for antibodies to 5 avian influenza virus antigens, using a protein microarray. General-population antibody titers against subtype H7 virus are higher than antibody titers against subtype H5 and lower than titers against H9...

The "R-75" strain live, attenuated, serum inhibitor-resistant influenza B vaccine was administered intranasally by drops in two doses 14 days apart to 21 volunteers. Each vaccinee was paired with a close associate (roommate or workmate) who similarly received two doses of a placebo solution. Although about 50% of both vaccine and placebo recipients complained of symptoms after dosage, the sever...

background and objectives : haemorrhagic septicaemia (hs), caused by pasteurella multocida, is the most important bacterial disease of cattle and buffaloes in india. oil adjuvant vaccine (oav) is the most potent vaccine available for the control of hs. the study aims to evaluate the effect of alum co-adjuvantation of oav on emulsion stability and immune response. materials and methods : two dif...

and Implications There was a significant direct correlation between the presence of Salmonella in ileocecal lymph nodes and the titer of antibody to Salmonella in meat juice. It was also demonstrated that there is no significant correlation between titer of antibody in serum collected from pigs immediately prior to slaughter and the presence of Salmonella in the feces on the floor of pens. Thes...

Objectives: To explore the expression of maternal serum IgG anti-A (B) and neonatal direct anti globulin, free antibody and Red Blood Cell (RBC) antibody on the occurrence and development of ABO Haemolytic Disease of the New-born (ABO-HDN) and provide a valuable reference for the early diagnosis of the disease. Methods: we selected 546 cases of jaundice and hyperbilirubinemia neonates in our ho...

Research has demonstrated that porcine circovirus type 2 (PCV2) can be shed into boar semen, raising the possibility that artificial insemination may be an important route by which disease associated with PCV2 is transmitted. The objective of this experiment was to determine the effect of vaccination against PCV2 on ejaculate characteristics and PCV2-specific antibody titers in serum of PCV2-po...
