4. Which of the following work to support Koch\'s Postulates? a. Serological tests showed that the sick individual produced antibodies against the pathogens, but healthy individuals did not. b. Salmonella was detected from the sandwich served at the school cafeteria where half the students had to be sent to the hospital with food poisoning. c.) An African village was wiped out by a mystery infection. A neighboring village sent two men to investigate since they had not heard from their friends for a week. Upon arrival, the men decided to bury the dead. A week later, these men also died of the same symptoms, eventually decimating their village also. d. Five computers in the office were found to be infected with a computer virus that allowed hackers to access their data. Five other computers were clean and therefore were not hacked.

Solution

Answer: The correct answers are C and D so would you please explain why C and D are the correct answer

The four Koch’s postulations are,

1). All the organisms suffering from the disease must contain the same pathogen and it should not be present in the healthy organisms.

2). The suspected causative microbe must be isolated from the affected organism and grown in microbial culture media.

3). The isolated organism \"should\" cause disease when introduced into an unaffected organism.

4). The microbe must be reisolated from the infected host and be identical to the inoculated microbe.

According to Robert Koch postulations, any infectious agent infects a host, resulted symptoms will be generated so that in the above case, if five computers in the office were found to be infected with a computer virus that allowed hackers to access their data, here symptoms of virus is to make computer software highly accessible to hackers. The isolated virus is going to cause, disease, when introduced into an unaffected computer. However, according to Koch postulate, five other computers were clean and therefore were not hacked. An African village was wiped out by a mystery infection. A neighboring village sent two men to investigate since they had not heard from their friends for a week. Upon arrival the men decided to bury the dead, after men died of same symptoms means. According to Koch\' postulates, the all the organisms suffering from the disease must contain the same pathogen and it should not be present in the healthy organisms & isolated organism \"should\" cause disease when introduced into an unaffected organism so that eventual decimating their village also
