The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
Chain of infection; the chain of events that lead to infection. There is a general chain of events that applies to infections, sometimes called the chain of infection [14] or transmission chain. The chain of events involves several steps – which include the infectious agent, reservoir, entering a susceptible host, exit and transmission to new ...
Bacillus cereus infection Culture Vancomycin: No multiple bacteria Bacterial meningitis: Lumbar puncture (contraindicated if there is a mass in the brain or the intracranial pressure is elevated), CT or MRI Antibiotics No multiple bacteria Bacterial pneumonia: Sputum Gram stain and culture, Chest radiography Antibiotics No
Maternal infections account for 2 to 4% of all clinically diagnosed S. pyogenes infections. [9] The risk of sepsis is relatively high compared to other bacterial infections acquired during pregnancy, and S. pyogenes is a leading cause of septic shock and death in pregnant and postpartum women. [10]
Streptococcus is a genus of gram-positive or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota. [2] Cell division in streptococci occurs along a single axis , thus when growing they tend to form pairs or chains, which may appear bent or twisted.
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
But, each type of skin infection caused by staph bacteria is different. A few common skin infections caused by staph bacteria are: Boils – Boils are the most common type of staph infection, they are pockets of white pus that start where a hair follicle or oil gland is. The boil is tender and red where the infection is located on the skin.
Streptobacillus is a genus of fastidious microaerophilic Gram-negative bacteria, which grow in culture as rods in chains. [2] Their species associated with infection is S. moniliformis. Their reported susceptibilities and therapies are penicillin and erythromycin.
