Bacterial Phylum Chlamydiae

Bacterial Phylum Chlamydiae

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 of...

Genital Herpes

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...

Sexually Transmitted Infections

Sexually Transmitted Infections

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...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

Trichomoniasis

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.

Bacterial Phylum Spirochaetes

Bacterial Phylum Spirochaetes

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 by a...

Area of Science:

Infectious Diseases
Public Health
Dermatology

Background:

Chancroid is a significant cause of genital ulcerative disease (GUD) worldwide.
Other common GUDs include syphilis, genital herpes, lymphogranuloma venereum, and donovanosis.
Chancroid is particularly prevalent in Africa, Asia, and Latin America.

Purpose of the Study:

To summarize the epidemiology of chancroid.
To highlight its global distribution and incidence compared to other GUDs.
To note its relative rarity in the United States.

Main Methods:

Literature review and synthesis of epidemiological data.
Comparative analysis of GUD incidence.
Geographic prevalence assessment.

Main Results:

Chancroid incidence can surpass that of syphilis in specific regions.
High prevalence observed in Africa, Asia, and Latin America.
Chancroid is considered uncommon in the United States.

Conclusions:

Chancroid remains a notable public health concern in many parts of the world.
Understanding regional variations in GUD prevalence is crucial for targeted interventions.
The low incidence in the US underscores the importance of surveillance and prevention strategies.
