We wished to develop criteria for serological confirmation of human T-lymphotropic virus type I (HTLV-I) infection in healthy donors. Selected serum or plasma samples reactive by HTLV-I enzyme immunosorbent assay or gel-agglutination assays with at least one viral-specific band on Western immunoblot (WIB) were tested in six laboratories by four WIBs and four radioimmunoprecipitation assays (RIP...
Three different groups of hemolysis mutants were produced by treatment of the M. pneumoniae FH-P24 strain with N-methyl-N-nitro-nitrosoguanidine. The first group of mutants, strains P24-L1, L2, and L11, showed wide and clear hemolytic zones, and attaching ability to erythrocytes and to hamster lung cells were the same as the properties of the parent strain and produced significant microscopic l...
BACKGROUND Bovine leukemia virus (BLV) is worldwide distributed and highly endemic in Argentina. Among the strategies to prevent BLV dissemination, a control plan based on the selective segregation of animals according to their proviral load (PVL) is promising for our dairy productive system. The objective of this work was to study the relationship between the blood PVL and the antibody level, ...
The objective of this study was to determine whether the maternal infecting human immunodeficiency virus (HIV) type 1 clade affects mother-to-child transmission frequency. Mothers in the mother-to-child HIV-1 transmission study in Nairobi, Kenya, were grouped by HIV-1 status of their first enrolled child: uninfected, perinatally infected, or postnatally infected. Restriction fragment length pol...
lactide)-b-poly (N-vinylpyrrolidone-co-N-acryloxysuccinimide) (PLA-b-P (NVP-co-NAS), 19000–22000 g.mol 1, PDI= 1.5) were prepared by nanoprecipitation and characterized in terms of size (DLS) and critical micellar concentration (cmc). Imiquimod was incubated with the aqueous micellar solution for 1 hour and imiquimod loading in the micelles was quantified by fluorimetry. The micelles were furth...
High-dose nevirapine treatment has been reported to confer sustained antiretroviral effects, despite a rapid development of resistance. The use of this strategy was evaluated in 20 previously untreated human immunodeficiency virus type 1 (HIV-1) p24 antigenemic persons with CD4 cell counts between 100 and 500/mm3. Treatment consisted of 400 mg of nevirapine, after a 2-week lead-in dose of 200 m...
Approximately 1%-10% of patients with HIV infection have been reported to have salivary gland enlargement. Parotid swelling in patients with HIV is often associated with salivary gland disease, including benign lymphoepithelial cysts (BLECs). The presence of BLEC can serve as an indicator of HIV infection, and the diagnosis of HIV-associated BLEC is usually based on clinical course, HIV confirm...
DAB389IL-2 is a genetically engineered fusion protein that reduces human immunodeficiency virus type 1 (HIV-1) replication in activated, interleukin (IL)-2 receptor (IL-2R)-expressing human peripheral blood mononuclear cells (PBMC). The level of infectious virus released by cultured PBMC after treatment with DAB389IL-2 was measured by a quantitative microculture assay. The inhibition of p24 ant...
