Summary
Antimicrobial resistance in Neisseria gonorrhoeae is a growing problem. The combination of cefixime and azithromycin shows promising synergistic activity against resistant strains in vitro.
Area of Science:
- Infectious Diseases
- Microbiology
- Pharmacology
Background:
- Neisseria gonorrhoeae causes common sexually transmitted infections with increasing antimicrobial resistance.
- High rates of resistance to ciprofloxacin, tetracycline, and penicillin G are reported in Japan.
- Existing oral antimicrobial therapies show reduced clinical efficacy due to resistance.
Purpose of the Study:
- To investigate the in vitro activity of various oral antimicrobial combinations against Neisseria gonorrhoeae.
- To identify synergistic combinations that could overcome antimicrobial resistance.
Main Methods:
- Testing the in vitro activity of combinations including beta-lactam/azithromycin, fluoroquinolone/azithromycin, and beta-lactam/fluoroquinolone.
- Evaluating synergistic effects of these combinations against Neisseria gonorrhoeae isolates.
Main Results:
- The combination of cefixime (a beta-lactam) and azithromycin demonstrated significant synergistic activity.
- Other tested combinations showed varying degrees of efficacy but less synergy compared to cefixime/azithromycin.
Conclusions:
- Cefixime plus azithromycin represents a potentially effective synergistic combination for treating gonorrhea, particularly in the context of rising antimicrobial resistance.
- Further clinical studies are warranted to confirm the efficacy of this combination in vivo.

01:26Sexually 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...
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.
01:26Bacterial 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...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:27Streptococcal 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...
