The morphological and cytochemical changes in HeLa cells infected with herpes virus have been studied at frequent intervals during infection and related to the growth of virus and the multiplicity of the virus inoculum. Infection with a high multiplicity inoculum produced enlargement and extrusion of small ribonucleoprotein (RNP) bodies in the nucleoli (nucleolini) to form RNP bodies in the nuc...

The deoxyribonucleic acid (DNA) of Escherichia coli B is converted by colicin E2 to products soluble in cold trichloroacetic acid; we showed previously that this DNA degradation (hereafter termed solubilization) is subject to inhibition by infection with phage T4 and that at least two modes of inhibition can be differentiated on the basis of their sensitivity to chloramphenicol (CM). This repor...

this study attempts to examine the multilingualism in algeria, in other words, the phenomenon of linguistic diversity which characterizes the algerian reality and its relationship. for that matter the article visualizes the linguistic level of learners especially children, highlighting the characteristics of the multiplicity of its causes and manifestations. here, the descriptive methodology is...

Replication of Human Immunodeficiency Virus type 1 (HIV) in infected CD4+ T cells represents a key driver HIV infection. The life cycle is characterised by the heterogeneity with respect to multiplicity infection and variability viral progeny. This can result from phenotypic diversity as well random effects fluctuations kinetics biochemical reactions underlying virus replication cycle. To quant...

High titers of interferon were induced by the psittacosis agent in guinea pig leukocyte cultures. Optimal yields of interferon were produced from freshly prepared guinea pig leukocyte cultures containing 4 x 106 cells per ml inoculated with a psittacosis/cell multiplicity of 1.0 and incubated at 35 C for 24 hr. Leukocytes obtained from 2to 4-month-old guinea pigs produced 20 times more interfer...

The genetic diversity of Plasmodium falciparum (P falciparum) infections in humans is implicated in the pathogenesis of malaria. This study provides the first estimate of the genetic diversity and genotype multiplicity of Plasmodium falciparum infection in children with uncomplicated P falciparum malaria in Osogbo, Nigeria. One hundred and one isolates were used for analysis of parasite populat...
