Pantoea

Pantoea

July 29th – Pantoea is a genus of Gram-negative bacteria of the family Enterobacteriaceae, recently separated from the Enterobacter genus. This genus includes at least 20 species. Pantoea bacteria are yellow pigmented, ferment lactose, are motile, and form mucoid colonies. Some species show quorum sensing ability that could drive different gene expression, hence controlling certain …

Bifidobacterium and Alloscardovia Omnicolens

July 28th – Most of the members of the genus Bifidobacterium, including the related organism Alloscardovia omnicolens, are inhabitants of the gastrointestinal tract and oral cavity of humans and animals and have been considered nonpathogenic for humans. However, the actual site of isolation and the clinical significance of A. omnicolens and of Bifidobacterium species are …

Enterobacter Cloacae

Enterobacter Cloacae

July 27th – Enterobacter cloacae is a clinically significant Gram-negative, facultatively-anaerobic, rod-shaped bacterium. Enterobacter cloacae is a member of the normal gut flora of many humans and is not usually a primary pathogen. Some strains have been associated with urinary tract and respiratory tract infections in immunocompromoised individuals. Treatment with cefepime and gentamicin has been …

Ehrlichia Chaffeensis

Ehrlichia Chaffeensis

July 26th – Ehrlichia chaffeensis is an obligate intracellular gram-negative species of rickettsiales bacteria. It is a zoonotic pathogen transmitted to humans by the lone star tick (Amblyomma americanum). It is the causative agent of human monocytic ehrlichiosis. Genetic studies support the endosymbiotic theory that a subset of these organisms evolved to live inside mammalian …

Coxiella Burneti

Coxiella Burneti

July 25th – Coxiella burnetii is an obligate intracellular bacterial pathogen, and is the causative agent of Q fever. The genus Coxiella is morphologically similar to Rickettsia, but with a variety of genetic and physiological differences. C. burnetii is a small Gram-negative bacterium that is highly resistant to environmental stresses such as high temperature, osmotic …

Chlamydia Psittaci

Chlamydia Psittaci

July 24th – Chlamydia psittaci is a lethal intracellular bacterial species that may cause endemic avian chlamydiosis, epizootic outbreaks in mammals, and respiratory psittacosis in humans. Potential hosts include feral birds and domesticated poultry as well as cattle, pigs, sheep and horses. Chlamydia psittaci is transmitted by inhalation, contact or ingestion among birds and to …

Campylobacter Coli

Campylobacter Coli

July 22nd – Campylobacter coli is a Gram-negative, microaerophilic, nonendospore-forming, S-shaped bacterial species within genus Campylobacter. At least a dozen species of Campylobacter have been implicated in human disease (campylobacteriosis), with C. jejuni and C. coli the most common. In humans, 85% to 95% of infections by the Campylobacter species involve C. jejuni, while C. …
