Structural Elucidation of [RNQ+] prions Transmissible Infectivity
… of toxicity and propagation. The transmissible infectivity of in vitro formed fibers were tested by introduction into yeast and assayed for any presence of heterogeneity. Significant phenotypic variation, similar to what is observed with mammalian prions strains, is observed within yeast also. …

Infectivity and Epidemiological Studies on Bovine Parvovirus
Bovine parvoviruses (BPV) are widespread in the cattle population and associated with disease of the reproductive and possibly with the respiratory tract. The virus has been recovered from cattle with clinical signs of respiratory disease. Four established cell lines (bovine turbinates (BT), Madin …

The Effects of Microwave Radiation on the Infectivity of Trichinella Spiralis
… The effects of microwave radiation on the infectivity of "Trichinella spiralis" in young, white, laboratory mice were studied. Procedure. Mice were divided into two groups: 1) mice receiving isolated, irradiated larvae and 2) mice receiving larvae which were isolated from irradiated …

Infectivity and pathogenicity of toxoplasma gondii in vitro and in vivo
… to play an important role in pathogenesis and infectivity in mice, though its role in the control of infection in rat is still not very clear. Therefore, DA and AO rats that differ in the level of IFN-y production were employed to get an insight into the pathogenicity and infectivity ofT. …

Factors Influencing the Distribution, Growth and Infectivity of Casuarina-Infective Frankia
… revealed that Casuarina cladodes increased the infectivity of a soil inoculum by a factor of 3.2, whereas leaves of a sympatric check plant, Terminalia catappa (Combretaceae), barely increased the same soil's infectivity. Charcoal and clay added to the seedling growth substrate to bind organic …

Nanomechanical Analysis of Coronavirus Spike proteins and Correlation with Infectivity and Lethality
… model is presented to make predictions on the infectivity and lethality of SARS-CoV-2 variants based on molecular motions and vibrational patterns of the virus spike protein. Our analysis shows that epidemiological virus properties can be linked directly to pure nanomechanical, vibrational …

Effect of Metabolic Enzymes on Amylopectin Content and Infectivity of Cryptosporidium parvum
… to decrease amylopectin stores and subsequently infectivity of Cryptosporidium parvum oocysts/sporozoites in both fresh oocysts and stored oocysts. In addition, glycolytic enzymes and substrates: glucose, glucose-1-phosphate, and glycogen synthase were investigated to determine if they can be …

The cellular and molecular basis of the Nef requirement for HIV-1 infectivity
… activities, Nef is essential for full HIV-1 infectivity, a function highly prominent in lymphoid cells. So far, the mechanism by which Nef promotes HIV-1 infectivity has remained elusive. Over the course of 3 years, my PhD research activity has led to the identification of the host …

Factors influencing the infectivity of the potato cyst nematodes, Globodera rostochiensis and G. pallida
… in G.rostochlensis, was correlated with impaired infectivity and delayed development. Interspecific comparisons indicated that G. pallida is better adapted to hatch at lower temperatures and has a much slower initial rate of hatch. Motility and lipid depletion of both species were fastest at the …

Compartmental Hepatitis B Virus (HBV) Evolution, Replication and Infectivity in vivo and ex vivo
Hepatitis B Virus (HBV) is classically considered a hepatotropic virus, however, the presence of different HBV genomic molecules in lymphoid cells and tissues support its lymphotropic nature. Our previous studies showed that HBV evolved in a compartment- and disease phase-specific fashion. However, …

Targeting of adenovirus serotype 5 infectivity to EGFRvIII-expressing cells using a bispecific CAR-scFv.
… cells that express this receptor. Adenovirus infectivity is primarily mediated by binding of the globular carboxyl terminus of its fiber protein, known as the knob domain, to the coxsackievirus and adenovirus receptor (CAR), which is expressed on various cell types. Although we attempted three …

Mathematical analysis of tuberculosis models with differential infectivity, general contact rates, migration and staged progression
… dynamics (variable contact rates, differential infectivity, migration and staged progression. The first model under consideration covers the general contact rates and differential infectivity. The second model explores migration and staged progression. In this model, the spread of tuberculosis …

The role of HIV-1 subtype B Envelope transmission motifs in subtype C variant infectivity
… important for subtype B Env expression and viral infectivity, in our own sequence analysis subtype C variants did not carry the transmission motifs and the aim of this study was to determine whether His12 and PNG413 was important for subtype C Env expression, processing, function and viral …

Maintaining pathogens with short infectivity in seasonally structured tick populations: relative importance of three transmission pathways
Infectivity periods of different tick-borne pathogens in host species can vary widely, and the variation affects how the pathogens are maintained in tick populations. In addition to systemic and vertical transmission, cofeeding transmission has been proposed as an important route for the …

Real Time PCR-Based Infectivity Assay and Characterization of Cell Surface Receptors for Turkey Hemorrhagic Enteritis Virus
… assay along with a cell culture system, a novel infectivity assay was developed for the titration of THEV, as an alternative for the endpoint dilution assay. Applying the assay on nine batches of commercial HE cell culture vaccines, high variations in infectious virus titers were detected. The …
