A single-celled microorganism that belongs to a group of prokaryotic organisms, characterized by the absence of a nuclear membrane and capable of reproducing predominantly by binary fission. It can take on various shapes including spherical, rod-like, and spiral, and plays a significant role in ecological systems, contributing to processes such as decomposition and nutrient cycling.
A type of microorganism commonly found in diverse environments, which can be either harmless or pathogenic, sometimes causing diseases in plants and animals while also being involved in fermentation and decay processes.
A microscopic organism that exists in various forms, often responsible for important biological processes and reactions, including some that can lead to infection; it thrives in numerous habitats, highlighting its adaptability and significance in natural systems.

A type of weapon that utilizes bacteria to cause illness or death in living organisms, often deployed in warfare or bioterrorism scenarios.
A biological agent that involves pathogenic microorganisms with the purpose of inflicting harm or destabilizing a population through infectious disease.
A form of weaponization that harnesses the harmful properties of bacteria to create a strategic advantage in conflicts or warfare contexts.
The scientific study focused on bacteria, encompassing their characteristics, behaviors, and interactions, which extends into the fields of medicine and agriculture.
A branch of microbiology that investigates the physiology, genetics, and ecology of bacteria, particularly in relation to their roles in various biological processes and diseases.
The discipline that explores the various types of bacteria, their structural and functional properties, and their impact on human health and the environment, aided by advancements in technology like molecular biology and electron microscopy.
A type of bacteria that derives energy from photosynthesis, using substances like hydrogen sulfide instead of oxygen-producing processes, which means they do not release oxygen during their metabolic activities. Examples include purple sulfur bacteria and green sulfur bacteria.
Bacteria that can convert light energy into chemical energy through photosynthesis, primarily living in anaerobic environments and utilizing alternative electron donors, thereby not contributing to oxygen generation.
Microorganisms capable of producing their own food using light energy, but unlike plants, they do not produce oxygen, often found in aquatic habitats where sulfur compounds are abundant.
Related to or characteristic of bacteria, which are microscopic single-celled organisms that can be found in various environments and can have both beneficial and harmful effects on living organisms.
Pertaining to a condition or disease caused by the multiplication or presence of bacteria in the body or in a specific environment.
Describing substances or properties that originate from or are influenced by bacterial activity.
