Insights

Four South African patients with HIV infection developed meningitis caused by Cryptococcus neoformans var. gattii, serotype C. This marks the first report of serotype C meningitis in individuals with human immunodeficiency virus (HIV).

Area of Science:

  • Medical Mycology
  • Infectious Diseases
  • Public Health

Background:

  • Cryptococcus neoformans var. gattii is an emerging cause of fungal infections.
  • Serotype C is a less common serotype of Cryptococcus neoformans var. gattii.
  • Human immunodeficiency virus (HIV) infection is a known risk factor for cryptococcal meningitis.

Purpose of the Study:

  • To report the first cases of meningitis caused by Cryptococcus neoformans var. gattii, serotype C, in patients with HIV infection.
  • To highlight the potential for this specific fungal serotype to cause severe infections in immunocompromised individuals.

Main Methods:

  • Case series presentation of four patients.
  • Clinical data collection and microbiological analysis.
  • Identification of Cryptococcus neoformans var. gattii, serotype C, through laboratory testing.

Main Results:

  • Four patients from South Africa diagnosed with meningitis.
  • All patients had concurrent human immunodeficiency virus (HIV) infection.
  • Causative agent identified as Cryptococcus neoformans var. gattii, serotype C.

Conclusions:

  • Cryptococcus neoformans var. gattii, serotype C, can cause meningitis in patients with HIV infection.
  • This case series represents the initial documentation of serotype C meningitis in HIV-positive individuals.
  • Further research is needed to understand the epidemiology and clinical implications of this specific fungal serotype in immunocompromised populations.

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...

Bacterial 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...
