Study Notes
Sexually Transmitted Diseases
- Syphilis is caused by Treponema pallidum and linked to the "Tuskegee Experiment."
- Congenital syphilis can be transmitted from mother to fetus, resulting in symptoms like nasal discharge and bone deformation.
- Primary syphilis is marked by the development of canchres from which fluid drains.
Zoonotic Diseases
- Leptospirosis is caused by Leptospira interrogans, often contracted through exposure to contaminated water or environments.
- Lyme Disease, transmitted by tick bites, often presents with a characteristic bulls-eye rash.
- A culture of spirochetes identified in the oral cavity of a syphilis patient is categorized under the genus Treponema.
Specific Pathogens and Their Diseases
- Borrelia hermsii is associated with Relapsing Fever, characterized by intermittent high fever episodes.
- Yaws, a nonsyphilitic Treponematoses, results in ulcers and lesions, particularly affecting children in Latin America.
- Bejel, or endemic syphilis, presents with skin lesions and is transmitted through shared utensils.
Gastrointestinal Pathogens
- Vibrio cholera causes secretory diarrhea, described as "rice water stool," and can lead to severe dehydration.
- Vibrio vulnificus is linked to gastroenteritis from raw oysters consumption.
- Helicobacter pylori produces urease, contributing to stomach ulcers, particularly in type O blood individuals.
Bacterial Characteristics and Diseases
- Cruciform bacteria are generally Gram-negative and associated with enteric diseases.
- Campylobacter jejuni and Campylobacter fetus are significant pathogens, with the latter linked to pneumonia in newborns.
- Mycoplasmas are unique bacteria without cell walls, leading to diverse ailments including pneumonia and urogenital infections.
Vector-Borne Diseases
- Rickettsia rickettsia is transmitted by ticks and causes Rocky Mountain Spotted Fever, which can be fatal if untreated.
- Epidemic typhus, resulting from lice bites, leads to a spotted rash and can affect the central nervous system.
- Coxiella burnetti transmissible materials include milk, urine, and droplets.
Oral Health and Dental Diseases
- Plaque consists of bacterial masses that produce acid, dissolving enamel and leading to dental caries.
- Dental caries and gingivitis are common conditions that can result in tooth loss if untreated.
- Streptococcus mutans is a key contributor to the early stages of tooth decay, particularly in individuals with high sugar intake.
Treatment and Prevention
- Tetracycline is effective against Mycoplasma pneumoniae, easing symptoms of respiratory infections.
- Scaling is a dental procedure aimed at removing calculus to prevent gingivitis development.
- Education on the importance of fluoride and a low-sugar diet can significantly reduce dental caries risk.
