Neisseria gonorrhoeae Sequence Type 16676 in Disseminated Infections, Minnesota, USA, 2025
Emerging Infectious Diseases
|June 2, 2026
Summary
A new Neisseria gonorrhoeae strain (ST-16676) caused disseminated infections in Minnesota. This rapidly emerging strain showed tetracycline resistance and was detected via genomic surveillance.
Area of Science:
- Microbiology
- Genomics
- Epidemiology
Background:
- Neisseria gonorrhoeae is a significant public health threat.
- Disseminated gonococcal infections (DGIs) represent a severe manifestation of gonorrhea.
- Emergence of antimicrobial resistance in N. gonorrhoeae complicates treatment and control efforts.
Purpose of the Study:
- To investigate an outbreak of disseminated gonococcal infections in Minnesota in 2025.
- To characterize the Neisseria gonorrhoeae strain responsible for the outbreak, including its genetic makeup and antimicrobial resistance profile.
- To evaluate the utility of prospective genomic surveillance in detecting and responding to infectious disease outbreaks.
Main Methods:
- Genomic surveillance was employed for early detection of the Neisseria gonorrhoeae outbreak.
- Epidemiologic investigation was conducted to understand the transmission dynamics.
- Whole-genome sequencing was performed to characterize the outbreak strain, including identifying specific sequence types and resistance genes.
Main Results:
- An outbreak of Neisseria gonorrhoeae sequence type 16676 was identified in Minnesota in 2025.
- The outbreak strain was associated with disseminated gonococcal infections.
- The identified strain exhibited rapid emergence, carried a plasmid with a tetracycline resistance gene, and encoded a porB1a allele.
Conclusions:
- Prospective genomic surveillance is effective for detecting and investigating Neisseria gonorrhoeae outbreaks.
- The emergence of ST-16676 highlights the need for ongoing monitoring of gonococcal antimicrobial resistance.
- Understanding the genetic characteristics of emerging strains is crucial for public health interventions against gonorrhea.

01:18Trichomoniasis
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.
01:29Bacterial 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...
01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
