Unexpectedly, I find microbiology interesting somehow
This audiovisual describes in detail the life cycle of the Onchocerca volvulus and its role in causing blindness in Ghana. Clinical examples of persons afflicted with this disease are shown to elucidate the effects of the disease. According to the presentation, the disease is transmitted by the bite of black flies of the family Simuliidae. The method by which the flies acquire the organism is carefully outlined, as is the process by which the infective larvae enter the wound and develop into male and female worms, which mate and cause a tissue reaction in man. This reaction produces fibrous nodules which often appear externally as lumps. If ocular invasion occurs, blindness can result. Treatment of the disease by surgical removal of the nodules or by administration of the drug diethylcarbamazine is discussed. Measures to control the breeding grounds of the flies with DDT are also noted.
Things you must know about Hantavirus [USMLE Quick Review] Orthohantavirus is a genus of single-stranded, enveloped, negative-sense RNA viruses in the family Hantaviridae within the order Bunyavirales. Members of this genus may be called orthohantaviruses or simply hantaviruses. Orthohantaviruses typically cause chronic asymptomatic infection in rodents.
A new, subvariant of Omicron has emerged, which some have begun calling “son of Omicron,” but public health officials say it’s too soon to tell what kind of real threat, if any, this new strain will present.
In the meantime, it’s worth watching BA.2, the World Health Organization says. The subvariant has been identified across at least 40 countries.
BA.2 accounts for only a small minority of reported cases so far. The one exception is Denmark, a country with robust genetic sequencing abilities, where estimates range from 50% to 81% of cases.
