The primary function of most endospores is to ensure the survival of a bacterium through periods of environmental stress. They are therefore resistant to ultraviolet and gamma radiation, desiccation, lysozyme, temperature, starvation, and chemical disinfectants.
Recurring Cold & Flu Symptoms. Hi, I've been struggling for the last 5 weeks with recurring cold & flu symptoms, a lot of sneezing, now i have a cough which is quite chesty, by the weekend i feel completely drained, somtimes quite achy during the evenings. I'm taking paracetomol extra, not suffering from high temp though.
Cold symptoms can be different for everyone, but they typically appear about one to three days after exposure to a cold-causing virus, peak around day four, and taper off around day seven. The most common cold symptoms include sore or scratchy throat, nasal congestion or stuffiness, a runny nose, and a cough.
