BACKGROUND While doxycycline is recommended as an alternative treatment of syphilis in patients with penicillin allergy or intolerance, clinical studies to compare serological response to doxycycline versus benzathine penicillin in treatment of early syphilis among HIV-infected patients remain sparse. METHODS We retrospectively reviewed the medical records of HIV-infected patients with early ...

Visceral leishmaniasis (VL) is a zoonotic disease caused by leishmania species. Dogs are considered to be the main reservoir of VL. A number of methods and antigen-based assays are used for the diagnosis of leishmaniasis. However, currently available methods are mainly based on direct examination of tissues for the presence of parasites, which is highly invasive. A variety of serological tests ...

BACKGROUND Medical students come into contact with infectious diseases early on their career. Immunity against vaccine-preventable diseases is therefore vital for both medical students and the patients with whom they come into contact. METHODS The purpose of this study was to compare the medical history and serological status of selected vaccine-preventable diseases of medical students in Ger...

Twelve hundred and twenty-seven clinical isolates and eighty stock strains of viridans streptococci were tested for serological and physiological characteristics. Because the serological reactions of these strains varied, a differentiation scheme could not be based on these reactions. For the same reason, there could be no correlation of serological characteristics with physiological characteri...

Twenty-one dairy herds with a history of Neospora caninum-associated abortions were used for a longitudinal serological study. A total of 1,676 animals were blood sampled 3 times and used to evaluate a single serological screening for N. caninum antibodies. The results of the first serological screening were compared with the results based on three consecutive samples, whereby two or more posit...

Strategies for the prevention of cancer include those aimed at reducing the incidence of cancer (primary prevention) and cancer mortality through early detection of tumors (secondary prevention). The efficacy of prevention interventions is evaluated by clinical trials. The conduct of clinical trials is aided by the use of serological indicators of the carcinogenic process measured using plasma ...

BACKGROUND/AIMS The present study was launched to systematically characterize the molecular genotypes and quantitative serological biomarkers during the natural course of chronic hepatitis B (CHB) infection in a patient population from Chongqing, China. METHODS A total of 140 patients were enrolled and grouped according to the natural phases of HBV infection: HBeAg (+) immune tolerance, immun...

BACKGROUND The optimal treatment of early syphilis (primary, secondary and early latent) in HIV-infected patients remains controversial. The Center for Diseases Control STD Treatment Guidelines recommended 1 dose of benzathine penicillin G (BPG) regardless of HIV infection. However, many providers modify the treatment for early syphilis. METHODS We performed a retrospective chart review of al...

a living body produces in the body antisubstances which react with the substance is an antigen. The anti-substance is an antibody which is found in the blood, plasma or serum and is contained in the serum globulin. Serological reactions are antigen-antibody reactions. They are also called immunological reactions or biological reactions. The serological technique sets up these reactions. It is a...
