Welcome to the Microbiology MCQs with Answers. In this post, we have shared Microbiology Online Test for different competitive exams. Find practice Microbiology Practice Questions with answers in Biology Tests exams here. Each question offers a chance to enhance your knowledge regarding Microbiology.

Microbiology is the science studying microorganisms: bacteria, viruses, fungi, and protozoa. Inquiry into diversity, physiology, and functions of these small organisms – contributors to ecological systems and human health, broadly gives microbiology its foundations. Understanding the microbial world and its implications in the environment, industry, and medicine is fundamental in the science of microbiology.

Major branches of microbiology involve bacteriology, virology, mycology, and parasitology. Bacteriology is concerned with the study of bacteria accompanied by their role in diseases. Virology, on the other hand deals with viruses, their interactions, and relationships between host and viruses. Mycology discusses fungi and their applications in both biotechnology and medicine while parasitology explores parasites that affect human and animals’ health.

The simple technologies include cultivation methods, microscopy, and molecular diagnostics. Breakthroughs in sequencing techniques and bioinformatics have transformed the field from relatively simple applications to very high-tech ones, allowing for detailed analyses of the microbial genome and its interactions.

Its applications include drug development and quality control in pharmaceuticals, health check on soil in agriculture, and in public health, with regard to infectious diseases, resistance to antimicrobial agents, and development of vaccines. That’s why it has a throbbing and essential application.
