Chronic Chlamydia trachomatis infections in infants
JAMA
|January 15, 1992
Summary
Many infants with Chlamydia trachomatis infections persist with the condition for months or years without treatment. This prolonged infection can be mistaken for abuse, highlighting the need for accurate diagnosis.
Area of Science:
- Pediatric Infectious Diseases
- Microbiology
- Immunology
Background:
- Chlamydia trachomatis is a common bacterial pathogen affecting infants.
- Congenital C. trachomatis infections can lead to prolonged illness if untreated.
Purpose of the Study:
- To investigate the natural history of Chlamydia trachomatis infections in infants.
- To understand the persistence and serovar-specific antibody responses in infected infants.
Main Methods:
- Bacteriologic and serologic study of an inception cohort of 22 infants with C. trachomatis infections.
- Monitoring infection persistence in various anatomic sites and antibody responses.
Main Results:
- 35% of infants remained infected at 1 year of age.
- One infant had persistent conjunctival, nasopharyngeal, and oropharyngeal infection for over 28 months.
- Serologic data indicated infection acquisition solely at birth, with matching serovars between mothers and infants.
Conclusions:
- Infants can harbor C. trachomatis infections for extended periods without antimicrobial therapy.
- Prolonged infant C. trachomatis infections may be misdiagnosed as sexually transmitted infections or abuse.

01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:22American 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...
