Question

Explain organ specific and tissue specific manifestation with examples

Answer 1

Organ specific manifestation is the ability or adaptation of a microbe, to infect specific organ of an organism in a particular type of disease, e.g. in case of TB, the organ infected is lungs.

Organ – Specific and Tissue-Specific Manifestations. The disease-causing microbes enter the body through these different means. ... The body is very large when compared to the microbes. So there are many possible places, namely the organs or tissues, where they could go.

Answer 2

Organ specific manifestation means that the pathogen which enters in the body finds or makes a particular organ its place of growth. Most of the time these microbes seems to have evolved to home in those organs which are some or the other way connected to the point of entry for example if they enter through air via nose they are most likely to go to the lungs and will make their manifestation point in the lungs where as tissue manifestation or tissue specific manifestation means that that microbes and pathogens grow in a particular tissue that those microbes and pathogens are very much particular about their growth in a particular tissue only and this is in the same way through the point of entry leading to a particular tissue. This need not to be always applicable for example in the case of AIDS HIV virus which enters through through sexual organs but gets spreads to the lymphatic nodes so it need not to be the case every time but most of the time it is .
