Jan 13 th Enteric virus – In GI tract. Transmission through inadequate hygiene ex. Meningitis – coating of spinal cord. Note list is fairly broad. Virus cultures – counting of placks takes about weeks. .. lack the technology to efficiently detect whether viruses exist in water. May test humans via antibodies (only present 10 days after infection), fecal sample ELISA – specific test to test for presence of protein Norwalk virus – RNA virus, low infectious dose, hard to decontaminate, stable in environment, can survive in low pH (stomach). Can test via antibodies but more commonly in stool samples. Calici virus because of its cupshape – infects humans; cannot study it because cannot culture it in lab or in animals. Astrovirus – RNA virus, person to person contact and water/sewage contamination. Virus do not have a lipid layer thus cannot be removed using detergents. Note virus do not exist in isolation in environment ex. Found in mucus – washing can eliminate mucus but DOES NOT KILL VIRUS. UV light will damage DNA killing virus. Adenovirus – person to person, water and food contamination.
