The primary infection by Pneumocystis of normal, healthy infants is asymptomatic and goes undiagnosed. Microscopy diagnosis of Pneumocystis was sought in lung impression smears (LIS) from two ~3-month-old infants dying unexpectedly in the community. Pneumocystis nuclei and cysts were identified using Hema-Gurr with subsequent Gomori-Grocott staining in the same spot documenting that these stains may be complementary. LIS provide for an observer-dependent, inexpensive, and ready-available method for detection of Pneumocystis in infant lungs.

In parallel with the introduction of modern therapeutic and pharmacological interventions that have successfully resolved many diseases and conditions, previously deemed incompatible with life, there has been a significant increase in the number of patients experiencing secondary immunodeficiency. As a result, these patients are highly susceptible to various opportunistic infections. Among these infections, pneumocystis pneumonia (PCP) stands out as one of the most frequent and potentially life-threatening ones, necessitating prompt diagnosis and treatment.

Importance: Patients with achalasia face a higher risk of developing esophageal cancer (EC), but the surveillance strategies for these patients remain controversial due to the long disease duration and the lack of identified risk factors.

Objective: To investigate the prevalence of esophageal Candida infection among patients with achalasia and to assess the association of Candida infection with EC risk within this population.

Design, Setting, And Participants: This retrospective cohort study included patients with achalasia diagnosed at or referred for treatment and monitoring to the Erasmus University Medical Center in Rotterdam, the Netherlands, between January 1, 1980, and May 31, 2024.

Variable surface antigen expression, virulence, and persistent infection by malaria parasites.

SUMMARYThe human malaria parasite is known for its ability to maintain lengthy infections that can extend for over a year. This property is derived from the parasite's capacity to continuously alter the antigens expressed on the surface of the infected red blood cell, thereby avoiding antibody recognition and immune destruction. The primary target of the immune system is an antigen called PfEMP1 that serves as a cell surface receptor and enables infected cells to adhere to the vascular endothelium and thus avoid filtration by the spleen.

SUMMARYSporotrichosis is a subacute-to-chronic infection endemic to tropical and subtropical regions. It usually involves subcutaneous tissue but can occasionally cause extracutaneous infections, especially in hyperendemic areas. Extracutaneous infections are classified based on the anatomic location of the lesion and the route of infection (primary or multifocal).
