Citrobacter koseri: Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes
Introduction Citrobacter koseri, formerly known as Citrobacter diversus, is a gram-negative bacterium that is a member of the Enterobacteriaceae family. It is an opportunistic pathogen capable of causing various infections, particularly in individuals with weakened immune systems or those who are hospitalized. It is a facultative anaerobe, meaning it can survive and grow in both the presence and absence of oxygen. It is motile due to the presence of flagella, which enables it to move within...
Morganella: Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes
Introduction Morganella is a genus of gram-negative bacteria belonging to the family Enterobacteriaceae. It was named after the bacteriologist Carl Wilhelm Julius Friedrich Julius Morgan, who first described it in 1906. The genus Morganella includes three species: M. morganii, M. psychrotolerans, and M. osloensis. Among the species in this genus, Morganella morganii is the most clinically relevant and frequently encountered. It is a facultative anaerobe, meaning it can survive in both aerobic (oxygen-rich) and anaerobic (oxygen-depleted)...
Citrobacter freundii: Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes
Introduction Citrobacter freundii is a species of Gram-negative bacteria that belongs to the Enterobacteriaceae family. It is a facultative anaerobe, meaning it can survive in both aerobic (oxygen-rich) and anaerobic (oxygen-deprived) conditions. It is commonly found in the environment, including soil, water, and sewage, as well as in the human gastrointestinal tract as part of the normal flora. While Citrobacter freundii is generally considered to be a harmless commensal bacterium, meaning it can coexist with humans...
