Rt-PCR probes targeted to different gene sequences of VEE (Venezuelan equine encephalitis) virus strain TC-83 were assessed for their sensitivity, specificity and non-specific cross-reactivity. A generic VEE virus amplimer (VNSP4F2/VNSP4R2), targeted against nsP4 was identified, which was sensitive (detected at least 10 pfu) and robust (worked over a wide(More)
We describe a multidisciplinary effort for creating interactive 3D graphical modules for visualizing optical phenomena. These modules are designed for use in an upper-level undergraduate physics course. The modules are developed in Open Inventor, which allows them to run under both Unix and Windows. The work is significant in that it applies contemporary(More)
Bacteriophage of Lactococcus lactis ssp. lactis and ssp. cremoris, isolated in the United States and Argentina, were compared with respect to host range, adsorption, latent period, burst size and immunological cross-reactivity. Only 1 out of 13 U.S. culture isolates was sensitive to Argentinian phage. Argentinian L. lactis ssp. lactis C2 mutants were(More)
Twelve strains of streptococci of serological groups N and D were isolated from rumen fluids of nine cows on four rations although both groups were not isolated from the same animal. The twelve were representative of a larger number of streptococci isolated by enrichment in milk. Generally, the physiological characteristics of the isolates indicated members(More)
Streptococcus lactis and Streptococcus cremoris have an important role in the fermentation of milk during the manufacturing of lactic products. Bacteriophages are spread in the plant environment and they may infect the starters causing technical and economic problems to the dairy industry. It is now known that the usual methods of control are not completely(More)
Three monoclonal antibodies (Mabs) specific for the envelope (E) protein of flaviviruses were evaluated for use in an antigen capture ELISA. Three combinations of Mabs and a combination of polyclonal antibodies (Pabs) were evaluated in antigen capture ELISAs for their ability to detect 18 flaviviruses. The Mab ELISAs detected 50% of flavivirus antigens with(More)
