Article Abstract
is a basidiomycetous yeast responsible for considerable HIV-related morbidity and mortality. A cachectic 26-year-old HIV-positive man with a CD4 count of 103 cells/μl presented with fever, breathlessness, and bilateral lower limb weakness. A brain computed tomography scan could not elucidate the neurological deficit. His blood was sent for culture and serum cryptococcal antigen detection, with the latter testing as negative. By the fourth day of admission, the patient's condition had deteriorated drastically. A lumbar puncture was performed, and like his serum sample, the cerebrospinal fluid also tested negative for cryptococcal antigens. By this time, was isolated from the admission blood culture. The laboratory diluted both the serum and cerebrospinal fluid specimens to retest for cryptococcal antigens, and finally, an antigen titer of ≥1:2560 was recorded.

Cryptococcosis is a fungal infection commonly found in immunocompromised individuals, but it can also affect immunocompetent individuals. A pregnant woman with myasthenia gravis, HIV-negative, died after a diagnosis of tuberculosis. An autopsy revealed a mediastinal mass and organ involvement, indicating a disseminated cryptococcal infection.

Cryptococcus is an opportunistic pathogen responsible for cryptococcosis, a fungal infection with high mortality, particularly in immunocompromised individuals. Accurate and rapid species identification is critical for effective diagnosis and treatment. This study developed and standardized a multiplex PCR protocol targeting the polymorphic PRP8 gene, a novel molecular marker proposed for differentiation of C.

In the wild, the nematode primarily feeds on microbes, which are abundant in rotting vegetation. Studies show that several gram-positive and gram-negative bacterial populations predominantly constitute the gut microbiome, but surprisingly lack any yeast species. To understand the lack of yeast in the intestine of , we studied the behaviour of worms on pathogenic and non-pathogenic yeast diets.

Background: Despite efforts to optimize therapy for HIV-associated cryptococcal meningitis (CM), survival outcomes remain poor. It is unclear how the cerebrospinal fluid (CSF) cellular immune phenotype and activation contribute to 2-week and 1-year survival following CM.
Methods: We compared baseline CSF mononuclear cell phenotype and activation among adults with HIV-associated cryptococcal meningitis who died within 2-weeks of CM diagnosis to survivors who were alive at 1-year.

Background: Tuberculosis (TB) and human immunodeficiency virus (HIV) infection are infectious diseases that pose serious threats to human health. TB and HIV can interact to promote the progression of diseases. This study aims to provide basic evidence for the formulation of disease prevention and control strategies.
