Immunocompromised persons are at increased risk for a large group of infections that are either uncommon or much less severe in the immunocompetent host. These opportunistic infections broaden the diagnostic considerations in differential diagnosis of community-acquired pneumonia in patients with immunodeficiencies. This article highlighted epidemiologic factors, clinical presentations, and treatment options for four selected opportunistic infections that represent varied classes of pathogens: nematodes (S stercoralis), mycoses (C neoformans), bacteria (P aeruginosa in patients with HIV infection), and viruses (measles virus).

Undetected chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections can lead to cirrhosis and liver cancer. Syrian migrants are the largest non-European migrant group in the Netherlands with HBV and HCV prevalence rates above 2%. This study aimed to reach Syrian migrants for HBV and HCV testing using point-of-care tests (POCT).

Introduction: Recurrent opportunistic infections are particularly common in patients infected with human immunodeficiency virus (HIV). However, these opportunistic infections have also been reported in HIV-negative patients, especially those with primary immunodeficiency disorder (PID), a condition that involves a large heterogeneous group of disorders arising from defects in immune system development and/or function.
Case: Here, we report a very rare case of recurrent opportunistic infections in a non-HIV-infected patient combined with mutations in complement component C6 and nuclear factor kB subunit 1 ().

Introduction: Opportunistic infections (IO) are infections of microbiota (fungi, viruses, bacteria, or parasites) that generally do not cause disease but turn into pathogens when the body's defense system is compromised. This can be triggered by various factors, one of which is due to a weakened immune system due to Diabetes Mellitus (DM), which increases the occurrence of opportunistic infections, especially in the oral cavity. Fungal (oral candidiasis) and viral (recurrent intraoral herpes) infections can occur in the oral cavity of DM patients.
