Sexually Transmitted Infections

943
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...

This manuscript describes the procedure to fabricate and characterize Griffithsin-modified poly(lactic-co-glycolic acid) electrospun fibers that demonstrate potent adhesive and antiviral activity against human immunodeficiency virus type 1 infection in vitro. Methods used to synthesize, surface-modify, and characterize the resulting morphology, conjugation, and desorption of Griffithsin from surface-modified fibers are...

Sexual Selection Class Simulation
ExpandNote: In this activity, you and your classmates will portray a sexually reproducing population consisting of an equal number of male and female animals. You will simulate several different mating scenarios to determine how relative quality, attractiveness, sex, and parental commitment affect mate choice and reproductive success. The goal of this activity is to maximize your progeny.
Hypotheses: There are several overall hypotheses for female and male...

Transmitting Plant Viruses Using Whiteflies

29.5K
Improving our understanding of and our ability to manage many of the insect-transmitted plant viruses requires the use of the vector. Insect transmission of plant viruses is a tritrophic interaction, and as such requires the manipulation of insects, virus, and plant. Vectors must be reared in large numbers and manipulated in such a way as to insure high rates of transmission to test plants. The basics of rearing and manipulating the whitefly, Bemisa tabaci (Hemiptera: Aleyrodidae), a vector of...

Area of Science:

  • Medicine
  • Infectious Diseases
  • Dermatology

Background:

  • Nonviral sexually transmitted diseases (STDs) can affect the perianal and anorectal regions.
  • Effective management requires understanding specific clinical presentations and treatment protocols.

Purpose of the Study:

  • To provide a practical overview for managing nonviral STDs in the perianal and anorectal areas.
  • To detail the clinical manifestations, diagnosis, and treatment for key nonviral STDs.

Main Methods:

  • Review of current medical literature and clinical guidelines.
  • Individualized discussion of specific nonviral STDs affecting the anorectal region.

Main Results:

  • Syphilis: Manifestations include chancres and condylomata lata; treatment involves penicillin.
  • Gonorrhea: Symptoms may include discharge and proctitis; treatment with ceftriaxone.
  • Chancroid: Characterized by painful ulcers; treated with azithromycin or ceftriaxone.
  • Donovanosis: Presents with granulomas; managed with azithromycin.
  • Lymphogranuloma venereum: Causes proctitis and fistulas; treated with doxycycline.

Conclusions:

  • Accurate diagnosis and timely treatment are crucial for managing nonviral STDs in the perianal and anorectal regions.
  • Adherence to evidence-based treatment guidelines ensures optimal patient outcomes and prevents complications.
