Answer 1

Ans :-76) option A. Faecal contamination.

Caliform are the bacteria which are present in water and faeces of all warm blooded animals. The presence of these bacteria in water indicates the contamination with faeces.

Ans :-79) option D. Shaking hands.

Mostly direct person to person transmission of disease occurs when fluid of infected person come in contact with healthy person as in case of AIDS. So, during shaking hands no transfer of fluid so disease would not be transmitted.

Ans :-80) option D. Clostridium perfringens :- tetanus

Campylobacter jejuni is one of most common cause of food poisoning in Europe and US. People can get its infection by eating raw or undercooked poultry or eating something that touched it.

Clostridium perfringens causes food poisoning if food infected with it is taken.

Treponema palladium is spirochaete bacterium. It is transmitted only in humans. It causes disease like syphilis.

Ans :-82) option B. All the micro organism associated with healthy human body.

We have 10 times as many microbial cells as humans have. The bacteria in microbiome help to digest our food, protect our body from pathogens, produce vitamins etc.

Ans :-83) option B. Direct transmission

Direct transmission occurs when there is physical contact with human to human. In case of indirect transmission there is no physical humqn to human contact .

Vector borne disease are transmitted by bite of infected arthropod such mosquitoes.
