Cell Culture, Cytopathic Effect and Immunofluorescence Diagnosis of Viral Infection

Viruses are obligate intracellular parasites that require living cells in order to replicate. Cell culture for propagation and identification of viruses is an important component of the clinical virology laboratory. In general, diagnostic tests can be grouped into three categories: direct detection, virus isolation and serology. Direct examination methods can usually give a result either within the same or the next day. Immunofluorescence is widely used for the rapid diagnosis of virus infections by detection of virus antigen in clinical specimens and detection of virus-specific antibodies.

Evaluation of Serum Vitamin D: An Institutional Study in Mumbai

Aim: The aim of the study was to evaluate the levels of serum 25(OH)D levels in patients to identify the average vitamin D levels, the incidence of insufficiency and deficiency amongst the patients reporting to a dental hospital in Mumbai. Methods: Serum 25(OH)D levels of 100 randomly selected patients who reported to Nair Hospital Dental College in Mumbai were assessed to evaluate the vitamin D status. Serum levels below 10 ng/mL were categorized as “deficiency “and between 29-11ng/mL were categorized as “insufficiency” of vitamin D.

Validation of an Anti-Protective Antigen ELISA for Quantitative IgG Evaluation in B. anthracis Immunized Horses

The potency test for anthrax vaccines has historically involved the challenge of actively or passively immunized laboratory animals with a fully virulent strain of Bacillus anthracis. Lethal challenge studies with the archetypal virulent strains such as B. anthracis Ames strain present considerable difficulties in laboratory management and handling and are too inefficient for the early evaluation of alternative preventative and therapeutic interventions. An ELISA for the evaluation of antibody response to protective antigen (PA) in horses immunized with the Sterne 34F2 strain spore vaccine was developed. The objective of this work was to study the performance of this assay in terms of the guidelines set forth by the International Conference on Harmonics (ICH) and the Center for Biologics Evaluation and Research (CBER) for analytical procedures. We have demonstrated a working range for this assay (73-1581 EU/ml) on the bases of the following parameters: linearity (25 and 1,662 EU/ml, r2 = 0.9988, p < 0.001), accuracy (94.8 - 105.4 %, recovery within the range of 25 and 1,662 EU/ml), precision (≤ 17.6 % CV, repeatability; ≤ 15.7 and ≤ 13.1 % CV, intermediate precision per day and per analyst, respectively), limit of detection (2.25 EU/ml) and limit of quantitation (25 EU/ml). The assay was also demonstrated to be specific for the evaluation of anti-PA IgG antibodies. Based on the assay performance characteristics it was determined that the assay was adequate for use in B. anthracis immunogenicity testing in horses.

Field Evaluation and Use of a Non Commercial Peptide Enzyme Immunoassay for Human Immunodeficiency Virus Serotyping in Abidjan (Ivory Coast)

In West Africa, where Human Immunodeficiency Viruses 1 and 2 (HIV-1 and HIV-2) co-circulate, serological assays allowing the reliable serotyping of HIV infection are needed.

AIDS: Signs to Management of the Disease

Acquired Immune Deficiency Syndrome (AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV). They get it after being infected with the HIV virus. HIV (human immunodeficiency virus) is a retrovirus that primarily infects components of the immune system.

Vertebro-Spinal Hydatidosis: Case Report

Hydatid disease is caused by the larval form of parasitic tapeworm; Echinococcus granulosus. Primary spinal hydatid disease is rare. Primary bone localization is rare and it accounts between 0.5% and 4%. Spinal localization accounts for less than 1%. The infection may be misdiagnosed initially.
