Diversity of Protists I01:15

Diversity of Protists I

769
Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Fungal Phylum Microsporidia

338
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Sexually Transmitted Infections

782
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...

Bacterial Phylum Chlamydiae01:29

Bacterial Phylum Chlamydiae

353
The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic...

Urinary Tract Infection II: Pathophysiology

491
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

5.3K
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
  • Public Health

Background:

  • Shigella flexneri is a primary cause of diarrhea in low socioeconomic countries.
  • Shigellosis epidemiology and mortality data are lacking in these regions.
  • S. flexneri is a significant food and waterborne pathogen globally.

Purpose of the Study:

  • Synthesis of information on prevention and control strategies.

Main Results:

  • Various S. flexneri serotypes are prevalent globally.
  • Increasing multidrug-resistant strains are emerging worldwide.
  • Resistance to third-generation cephalosporins, azithromycin, and fluoroquinolones is rising.

Conclusions:

  • Continuous surveillance of antibiotic resistance is crucial for updating treatment guidelines.
  • Preventive measures including safe water, sanitation, and vaccine development are essential.
  • Addressing the burden of shigellosis requires a multifaceted approach.
