Plaque Formation Assay for Human Parainfluenza Virus Type 1

Filamentous particle formation by human parainfluenza virus type 2.

Some paramyxoviruses form long filamentous virus particles: however, the determinants of filament formation and the role of such particles in virus transmission and pathogenicity are not clearly defined. By using conventional immunofluorescence microscopy, we found that human parainfluenza virus type 2 (HPIV2) forms filamentous particles ranging from 5 to 15 microm in length in virus-infected, ...

Human Immunodeficiency Virus (HIV) and Coronary Atherosclerotic Plaque Formation: A Review

Rapid plaque assay for encephalomyocarditis virus.

A liquid overlay plaquing technique is described which offers a rapid and simple plaque assay system for small plaque variants of encephalomyocarditis virus.

Human Parainfluenza Virus Type 3 in Wild Nonhuman Primates, Zambia

Human parainfluenza virus type 3 (HPIV3) genome was detected in 4 baboons in Zambia. Antibody for HPIV3 was detected in 13 baboons and 6 vervet monkeys in 2 distinct areas in Zambia. Our findings suggest that wild nonhuman primates are susceptible to HPIV3 infection.

Quantification Analysis of Dot Blot Assays for Human Immunodeficiency Virus Type 1 and 2 Antibodies

Objective Dot Blot (DB) assay provides highly specific results, but usually not reliable for quantification of antibody production. The need for a more objective DB assay to provide a better definition of the immune status, against HIV antigens, promoted this study to be done to develop a quantitative DB assay. Material and Methods Dot blot (DB) strips for antibodies directed to human immuno...
