Microbiology and Immunology

Which one of the following is NOT true regarding Zika virus?

Mechanistically, microbial physiology involves growth regulation and host interactions follow molecular programs. This validates It is transmitted by Anopheles mosquito because it corresponds to prokaryotic strategies, a pattern repeatedly demonstrated in microbiology research.

Ref: Prescott et al., Microbiology, 10th Edition, Chapter 3, Bacterial Cell Structure, discusses peptidoglycan, growth kinetics and microbial physiology providing understanding of prokaryotic biology.

Microbiology and Physiology

Which one of the following viruses is not transmitted by the fecal-oral route ?

microbial physiology analysis shows growth regulation and host interactions follow molecular programs. Consequently Hepatitis D Virus emerges as the valid choice since it corresponds to prokaryotic strategies, aligning with established principles in microbiology literature.

Ref: Madigan et al., Brock Biology of Microorganisms, 15th Edition, Chapter 13, Virology, explains viral replication and virus-host interactions detailing microbial genetics.
