Abstract

Insights

This study identifies Haemophilus pittmaniae and Haemophilus sputorum as new causes of urethritis in men who have sex with men. Antibiotic susceptibility testing showed these bacteria are treatable with common antibiotics.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Urology

Background:

  • First-time report of Haemophilus pittmaniae and Haemophilus sputorum associated with urethritis.
  • Focus on men who have sex with men engaging in unprotected intercourse.

Purpose of the Study:

  • To investigate the association of specific Haemophilus species with urethritis.
  • To determine the antibiotic susceptibility of isolated pathogens.

Main Methods:

  • Urethral exudate cultures and PCR for common genital pathogens.
  • Identification of microorganisms using MALDI-TOF mass spectrometry.
  • Antibiotic susceptibility testing via diffusion gradient method.

Main Results:

  • Haemophilus pittmaniae and Haemophilus sputorum were successfully isolated.
  • Both species demonstrated susceptibility to ampicillin, cefixime, and trimethoprim/sulfamethoxazole.
  • Specific susceptibilities noted for H. pittmaniae (tetracycline) and H. sputorum (moxifloxacin).

Conclusions:

  • Increased prevalence of potentially resistant Haemophilus species in genital infections.
  • Highlights the need for enhanced surveillance of these bacteria.
  • Recommends considering Haemophilus spp. in the differential diagnosis of genital infections.

Sexually Transmitted Infections01:26

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...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

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.

Bacterial Phylum Spirochaetes01:30

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...

Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Urinary Tract Infection II: Pathophysiology

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...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
