Procedures for In Vitro Cultivation of Treponema pallidum, the Syphilis Spirochete
Published on: January 24, 2025
[Syphilis as a chronic systemic infection].
Summary
Syphilis infections in Russia are rising, with a significant increase in latent forms. Factors like asymptomatic cases and antibiotic misuse contribute to the chronicity of this serious infection.
Area of Science:
- Infectious Diseases
- Epidemiology
- Microbiology
Context:
- The last Sexually Transmitted Diseases (STDs) epidemic in Russia (1994-2004) saw over 2.7 million syphilis infections.
- Current syphilis morbidity shows 37% latent forms, with 1.5% being late latency.
Purpose:
- To analyze the contributing factors to the increased prevalence of latent and late latent syphilis.
- To discuss the mechanisms behind the chronicity of syphilitic infections.
Summary:
- Increased late latency in syphilis may stem from a rise in asymptomatic cases, misuse of antibiotics, concurrent chronic viral infections (herpes, hepatitis B/C) affecting immunity, and substance abuse reducing treatment efficacy.
- Syphilis chronicity can be attributed to treponemes' inert cell surface, lack of outer membrane proteins, protected niche, and incomplete macrophage phagocytosis.
Impact:
- Highlights the persistent challenge of syphilis as an "infectio magna" requiring vigilant diagnostic and therapeutic approaches.
- Emphasizes the need for comprehensive management strategies to combat the rising rates of latent syphilis and its complications.

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...
Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
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...
American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
Stages of Infection
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...
Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
