What are bacteria? Characteristics Features of bacteria Bacteria, as microscopic entities, exhibit a unique assemblage of features that distinguish them from eukaryotic organisms, fundamentally setting them apart within the vast expanse of biological taxa. These features are emblematic of their evolutionary lineage and functional adaptability, encapsulating their cellular architecture, metabolic pathways, and ecological roles. Size … Read more

What are Mesophiles? Habitat of Mesophiles Mesophiles are microorganisms that prefer moderate temperatures, typically thriving in environments ranging from 20°C to 45°C (68°F to 113°F). Their habitats are diverse and include a variety of natural and human-made settings. Adaptations of Mesophiles Mesophiles, organisms that thrive in moderate temperature environments, have developed specific adaptations that allow … Read more

Domain: Bacteria Phylum: Actinomycetota Class: Actinomycetia Order: Bifidobacteriales Family: Bifidobacteriaceae Genus: Gardnerella Species: G. vaginalis What is Gardnerella Vaginalis? Gardnerella vaginalis is a micro-aerophilic coccobacillus that is a constituent of the vaginal microbiota. This bacterium, while present in the vaginal flora, does not inherently lead to bacterial vaginosis unless its populations become predominant. Contrary to some … Read more

What is Campylobacteriosis? Campylobacteriosis is a common bacterial infection that primarily affects the gastrointestinal tract, leading to gastroenteritis. Here is some information about campylobacteriosis: Efforts to prevent campylobacteriosis focus on ensuring food safety, particularly in relation to poultry products, by implementing good hygiene practices during production, processing, and preparation. Public awareness campaigns about safe food … Read more

Salmonellae are common infections in both humans and animals. They practically populate any animal, including livestock, poultry, birds, reptiles, rodents, domesticated animals, and people. One of three clinical syndromes, such as gastroenteritis, enteric fever, or localised disease, are frequently brought on by salmonella infections in humans. Salmonella infections in animals also result in significant losses … Read more

Here are the key biological characteristics of Shigella: Sources and transmission of Shigella infection Epidemiology of Shigella infection The epidemiology of Shigella infection provides insights into the historical background, transmission dynamics, and global burden of … Read more

What is Vibrio parahaemolyticus Food Poisoning? Vibrio parahaemolyticus food poisoning is a type of acute gastroenteritis caused by the consumption of raw or undercooked seafood products contaminated with the bacterium. Here is information about Vibrio parahaemolyticus food poisoning: Characteristics of Vibrio parahaemolyticus Vibrio parahaemolyticus is a bacterium with distinct characteristics that contribute to its physiology and … Read more

Escherichia coli, commonly referred to as E. coli, is a type of Gram-negative bacterium. It is facultative anaerobic, meaning it can survive in environments with or without oxygen, and has a rod-shaped morphology. E. coli is predominantly found in the lower intestine of warm-blooded organisms, including humans (endotherms). Human strains of E. coli can be … Read more

Enteropathogenic Escherichia coli (EPEC) Enteropathogenic Escherichia coli (EPEC) are a group of strains of Escherichia coli that have been associated with diarrheal illnesses. The understanding of EPEC has evolved over time with the discovery of different mechanisms of pathogenesis. Here is a summary of the key points about EPEC: Advancements in techniques and a better … Read more

What is Enteroaggregative E. coli (EAEC)? Disease Caused by Enteroaggregative E. coli (EAEC) Pathogenesis Mechanism of Enteroaggregative E. coli (EAEC) The pathogenesis of Enteroaggregative Escherichia coli (EAEC) involves several stages and mechanisms. EAEC is primarily transmitted through the fecal-oral route, often through contaminated food and water sources. The pathogenesis of EAEC is a complex process … Read more
