Lentiviruses (LV) are nononcogenic viruses, belonging to the Lentivirinae subfamily. The name comes from the Latin word “lenti”, meaning “slow”. According to the definition of B. Sigurdsson, they are causing infections in a limited number of hosts with a long incubation period (months and years) and progressive course, accompanied by damage in definite organs/tissues and a lethal outcome (Sigur...

conclusions in conclusion, the prevalence of hbv infection was low in the south of iran, but genotype d represented the major hbv genotype in this population. among the variables, age, duration of hd, history of blood transfusion, and using shared hd devices influenced the prevalence of hbv among hd patients. results both kinds of assay determined that nine (5.88%) patients were hbv positive (h...

conclusions prevalence of hiv/hcv coinfection is considerably low in turkey. the extremely rare prevalence of idu might have a role in this low prevalence. background rate of coinfection with human immunodeficiency virus (hiv) and hepatitis c virus (hcv) varies in different countries. this may be attributable to common transmission routes as well as social, economic, and cultural factors. objec...

The term “slow infection” was introduced for the first time by the Icelandic researcher B. Sigurdsson in 1954 (Sigurdsson, 1954). With this term, he designated the interaction of the virus with the host, characterized by a prolonged (many months and even years) incubation period, at what time several organs or systems become affected and thereafter, results in slow, but progressive development ...

conclusions hiv/hcv co-infection is an important medical problem in north-eastern poland. a history of incarceration and younger age at hiv diagnosis were additional to idu risk factors for hcv seropositivity in this cohort. patients and methods adult hiv-1 infected patients, with at least one antihcv result, treated in one of polish hiv/aids reference centers, participated in this cross-sectio...

Cell-associated bovine immunodeficiency virus (BIV) and cell-free BIV were subjected to increasing temperatures, including pasteurization conditions. To determine the effect of heat treatment on BIV viability, reverse transcriptase activity and infectivity of the heat-treated virus were assessed. BIV was inactivated by heating to 47 degrees C for 30 min and by low- and high-temperature pasteuri...
