Bacterial Phylum Spirochaetes01:30

Bacterial Phylum Spirochaetes

58
Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Skin Diseases and Disorders

4.0K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Sexually Transmitted Infections

387
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

4.3K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Clinical Science

Background:

  • In 2015, two novel species related to Staphylococcus aureus were proposed.
  • Staphylococcus argenteus represents one of these newly identified species.

Discussion:

  • This study details five isolates of Staphylococcus argenteus from human infections.
  • The isolates were associated with bacteremia and skin and soft tissue infections.

Key Insights:

  • This marks the first identification of Staphylococcus argenteus in South America.
  • The findings confirm S. argenteus as a cause of both community-acquired and nosocomial infections.

Outlook:

  • Further research is needed to understand the epidemiology and clinical significance of S. argenteus.
  • Surveillance for S. argenteus in South America and globally is recommended.
