17. Antiserum may be described as -A) blood serum which contains Antibodies.
Usually Antiserum consist of Blood serum which is having antibodies one or more than one type of antibodies which provides immunity against specific antigens.
It can be artificially induced in different animals like mice, guinea pigs, hamsters, rabbits, horse etc. Antigen is injected to animals , so their body gives immune response. During giving immune response antibodies for that Antigen are produced by animal. So animal is having antibodies in the blood serum which is called as Antiserum.
21. Dignosis of infectious agents may include following levels- Answer is D. ALL OF THE ABOVE
Clinical observation, Antibody response, Isolation and Identification of causative agent. All three levels gives accurate diagnosis of disease. Especially for multidrug resistant microbes isolation, identification is essential.Clinical observation gives idea about which kind of infection it is?,antibody response tells about body's response against pathogen whether it is providing immunity or antigen concentration is increased. When infection becomes diificult to control or to determine particular strain of bacteria and giving treatment particularly against it, it is essential to isolate and identify pathogen.
