Aim. Screening of vegetable crops for mixed viral infections caused by 8 viruses, and evaluation relative share different combinations pathogens using serological methods plant virus diagnostics. Methods. Double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was performed detection antigens. Results. For this study, the samples from plants with virus-like symptoms were collecte...

The aim of the present was to evaluate the prevalence of H9N2-specific antibodies among water buffaloes (Bubalus bubalis). To this end, blood samples were obtained from 80 randomly selected water buffaloes, 40 cases of which were obtained in the winter months, and 40 cases were sampled in the spring months. The presence of H9N2-specific antibody was determined by hemaggl...

Serological diagnosis of an acute infection can be done by the demonstration of seroconversion and/or agent-specific IgM antibodies in the serum samples. Seroconversion describes 4 fold or more increase in antibody levels of the serum samples which is collected at the acute and convelescent phase (10-15 days intervals) of an infection. As the detection of seroconversion is time-consuming, the a...

It is rather curious that, although ser for a multitude of constituents in and haematological laboratories, the ter has come to imply almost exclusively the ( of serum for antibodies, and, in part bodies related to microbial diseases serological techniques tend to be regarde as the prerogative of microbiologists. When one considers for how long a extent in biochemical laboratories the of tests ...

OBJECTIVE Recent studies have identified a set of serological markers for telomere dysfunction and DNA damage. The relevance of these serological markers in type 2 diabetes remains elusive. We investigated the association of serological markers (elongation factor 1α [EF-1α], stathmin, and N-acetyl-glucosaminidase) with leukocyte telomere length, a functional variant of uncoupling protein-2 (UCP...

BACKGROUND Following a suspected outbreak of scrub typhus in Kurseong, Darjeeling, the Armed Forces Medical College, Pune was requested by the National Institute of Epidemiology and the State authorities to undertake investigation of the ongoing scrub typhus outbreak and suggest containment measures. MATERIALS AND METHODS The epidemic team undertook clinical, entomological and serological stu...

In spite of extensive research devoted to all aspects of the problem of trichomoniasis (reviewed by the Societe fran9aise de gynecologie, '1957), we still know little about the factors which determine the severity of the infection. The clinical reaction to infection with Trichomonas vaginalis varies from the symptomless carrier state to acute vaginitis, and this variation might, in theory, be d...

We present a case of probable tuberculous meningitis in which serological changes 'diagnostic' of herpes simplex encephalitis were found. Evidence is provided that the serological changes in this case represent a true false positive, and that reliance on clinical plus serological criteria to diagnose herpes simplex encephalitis could result in failure to diagnose and treat tuberculous meningitis.

BACKGROUND Plague is endemic within the central highlands of Madagascar, where its main reservoir is the black rat, Rattus rattus. Typically this species is considered susceptible to plague, rapidly dying after infection inducing the spread of infected fleas and, therefore, dissemination of the disease to humans. However, persistence of transmission foci in the same area from year to year, supp...
