I know this is old but psuedomonas can also be found in the lungs, and its got a weird rotten but sweet smell when in the lungs... ick - Respiratory Therapist
Yike, APIC didn't take the time to review and expound on the correct definitions. Infectivity - is the ability of an agent to cause infection in a susceptible host, or the proportion of exposed persons who become infected. (# infected/# exposed)
Pathogenicity - the ability of a microbial agent to induce disease or the proportion of infected individuals who develop clinically apparent disease. (# ill/# infected)
Virulence - is the severity of the disease after the infection occurs, or the proportion of clinically apparent cases that are severe or fatal. (#severe cases/#total cases)
Infective dose - number particles to cause infection An inoculum size is the needed concentration of microorganisms for a standard test.
Immunogenicity - is the ability of an organism to produce an immune response after an infection that is capable of providing protection against reinfection with the same or similar organism. Chicken pox (varicella) and measles has a high pathogenicity, high infectivity, but low virulence. Meaning it is easy to get infected, and it will produce a disease reaction (lesions, etc.) but the virulence, is low, meaning the disease is not severe. Leprosy has a low infectivity, and low pathogenicity, but high virulence. It is difficult to get, and it is unlikely to develop disease, but if it does, the virulence is severe, so the person has debilitating results. Polio has high infectivity, low pathogenicity, and low virulence. Only 25 out of 100 people with polio will develop symptoms which are minor. And the virulence is low because only 1% will develop paralysis. The ability to multiply and grow is a bad definition, because the pathogen is still multiplying and growing whether you have a severe reaction or not.
biofilms on intravascular devices - think you have something and a Dissertation topic on your hands!!
Thank you so much! I had a lot of help watching your videos! :)
please google drive link

Hi, i just want to ask about contact precaution. Do we need to have a certain colony count for a bacteria to be considered under contact precaution?
Thank you ❤
Can you put the link to the google drive here please?

Thank you, I was just about to comment on that.
Where i can find practice test
Hi, Do you have any class currently running?
