Infection of a traumatic pelvic hematoma with Mycoplasma hominis
Sexually Transmitted Diseases
|April 1, 1978
Abstract:
Fever developed in a previously healthy young man who had sustained extensive pelvic trauma. Mycoplasma hominis was isolated in pure culture from six of seven specimens taken from a retroperitoneal hematoma over a one-week period, and mycoplasmacidal antibodies were present in high titer in the convalescent-phase serum. The fever abated after thorough surgical drainage of the infected hematoma.
Insights
A previously healthy man developed a fever after pelvic trauma. Mycoplasma hominis infection in a retroperitoneal hematoma was successfully treated with surgical drainage.
Area of Science:
- Infectious Diseases
- Trauma Surgery
- Microbiology
Background:
- Pelvic trauma can lead to complications such as hematoma formation.
- Retroperitoneal hematomas are potential sites for microbial infections.
- Early identification and management of infections are crucial in trauma patients.
Observation:
- A young man with extensive pelvic trauma developed a fever.
- A retroperitoneal hematoma was identified as the source of infection.
- Mycoplasma hominis was consistently isolated from the hematoma.
Findings:
- Mycoplasma hominis was identified as the causative agent of the retroperitoneal hematoma infection.
- High titers of mycoplasmacidal antibodies were detected in the patient's serum during convalescence.
- Surgical drainage of the infected hematoma led to the resolution of the fever.
Implications:
- Mycoplasma hominis should be considered in the differential diagnosis of infections following pelvic trauma.
- Prompt surgical intervention and source control are vital for managing such infections.
- This case highlights the importance of microbiological investigation in complex trauma cases.

01:25Urinary 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...
01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
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...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
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.
01:22Bacterial 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...
