Insights

Coinfection with microsporidiosis and cryptosporidiosis is reported in an HIV-infected newborn. Early diagnosis through systematic screening is crucial for managing these opportunistic intestinal infections in immunocompromised infants.

Area of Science:

  • Medical Microbiology
  • Infectious Diseases
  • Pediatrics

Background:

  • Microsporidiosis and cryptosporidiosis are opportunistic infections causing severe intestinal disease in immunocompromised individuals.
  • These infections pose a significant threat, particularly to vulnerable populations like newborns with HIV.

Observation:

  • A case of microsporidiosis-cryptosporidiosis coinfection was identified in a 17-day-old, exclusively breastfed, HIV-infected female newborn.
  • The newborn had no known animal contact, suggesting an alternative transmission route.

Findings:

  • Systematic stool sample screening using specific staining and PCR confirmed the coinfection.
  • Two microsporidia species (Encephalitozoon intestinalis, Enterocytozoon bieneusi) and Cryptosporidium hominis were identified.
  • Human-to-human transmission, likely from the mother, is the probable source of infection.

Implications:

  • This case underscores the importance of systematic screening for intestinal microsporidiosis and cryptosporidiosis in HIV-infected newborns.
  • Early detection and management are vital for improving outcomes in immunocompromised infants with these infections.
  • Highlights the potential for direct human-to-human transmission of these pathogens in neonatal settings.

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,...

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

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...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...

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...
