Study Notes
Gram-Negative Bacilli and Coccobacilli
-
Proteobacteria Delta Class: This class poses no known threat to humans, making them irrelevant in medical contexts.
-
Kingella: A member of the Beta Proteobacteria class linked to infections in the oropharynx, osteomyelitis in children, and gingival infections leading to endocarditis.
-
Bordetella pertussis: Utilizes virulence factors, including toxins that primarily cause destruction of respiratory tissues in young children.
-
Escherichia: Contains five pathogenic strain categories: enteropathogenic, enterotoxigenic, enterohemorrhagic, enteroaggregative, and enteroinvasive.
-
Proteeae Tribe Exclusion: Moraxella is not included in the taxonomy of the tribe Proteeae within the family Enterobacteriaceae.
-
Salmonella: Responsible for the majority of enterocolitis cases resulting from the consumption of contaminated foods.
-
Yersinia: Historically known for causing the Black Plague during the Middle Ages and continues to exist in modern times.
-
Pasteurella: Often associated with infections resulting from animal bites or scratches.
-
Haemophilus ducreyi: An opportunistic pathogen affecting groups such as alcoholics, sex workers, and injection drug users; causes the disease known as chancroid.
-
Vibrio Species Transmission: Vibrio parahaemolyticus and Vibrio vulnificus can be transmitted through the ingestion of raw oysters.
-
Campylobacter fetus: An opportunistic human pathogen that can cause spontaneous abortions in sheep and cattle.
-
Helicobacter pylori: Believed to be a causative agent of peptic ulcer disease in humans.
-
Porphyromonas gingivalis: Implicated in the development of atherosclerotic plaques related to inflammation stemming from periodontal biofilms.
