Summary
Haemophilus species (spp.) are rare causes of urethritis, often linked to unprotected sex. Multidrug-resistant strains are emerging, necessitating consideration for persistent symptoms.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Urology
Background:
- Haemophilus species (spp.) are uncommon pathogens implicated in urethritis.
- Understanding their characteristics is crucial for effective diagnosis and treatment.
Purpose of the Study:
- To characterize patients with positive urethral samples for Haemophilus spp.
- To investigate the prevalence and antibiotic susceptibility of Haemophilus spp. in urethral infections.
Main Methods:
- Retrospective study conducted at Bordeaux University Hospital (January 2018 - July 2019).
- Analysis of urethral samples positive for Haemophilus spp.
- Antibiotic susceptibility testing performed on isolated strains.
Main Results:
- Haemophilus spp. identified in 10 urethral samples from nine patients (mean age 33.8 years).
- Most patients reported unprotected sexual activity.
- Haemophilus parainfluenzae (9 samples) and Haemophilus influenzae (1 sample) were identified.
- All tested Haemophilus spp. showed resistance to amoxicillin and tetracycline.
- One case of persistent urethritis due to multidrug-resistant Haemophilus parainfluenzae was observed.
Conclusions:
- Haemophilus spp. represent a rare etiology of urethritis.
- Consideration of Haemophilus spp. is important for persistent urethral symptoms.
- The rise of multidrug-resistant Haemophilus spp. poses a significant clinical challenge.

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...

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...

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...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
