Dr. Marianne Black

Marianne Black is a South African infectious diseases researcher whose work centers on HIV-associated infections, antimicrobial resistance, and clinical microbiology. Affiliated with major academic hospitals and national surveillance networks, her research addresses the intersection of HIV, tuberculosis, and emerging pathogens within high-burden settings. Her scholarship reflects strong engagement with public health priorities in South Africa.

Her publications explore rifampicin-resistant tuberculosis diagnostics, non-tuberculous mycobacterial disease in people living with HIV, and complex opportunistic co-infections. She has contributed to national laboratory-based surveillance on Acinetobacter baumannii and bacterial meningitis, highlighting resistance patterns, mortality risks, and sequelae. Work on SARS-CoV-2 shedding among immunocompromised patients further demonstrates expertise in viral–host dynamics in vulnerable populations.

Across these studies, key strengths include antimicrobial stewardship, evaluation of diagnostic concordance, and analysis of clinical outcomes in resource-limited contexts. Her contributions support evidence-based treatment strategies, strengthen surveillance systems, and inform policy on antimicrobial resistance and HIV-related infectious complications.
