New aspects of the life cycle of Pneumocystis carinii

Zeitschrift Für Parasitenkunde
M E VossenJ H Meuwissen


Pneumocystis is recognized as a cause of pneumonitis in vertebrates, including man. So far an extra-cellular life cycle has been proposed; thick-walled cysts are the site of the formation of so-called intracystic bodies. These intracystic bodies are set free and are supposed to develop into free living thin-walled Pneumocysts ("trophic" stage) (Seifert and Pliess, 1960; Vavra and Kucera, 1970; Campbell, 1972). In this paper we present, based on elaborative ultrastructural studies, data on the existence of both intra-cellular and extra-cellular stages of the parasite which result in a new proposal for the life cycle of the parasite. This short communication will be followed by a more detailed description of our observations.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration

HLA Genetic Variation

HLA genetic variation has been found to confer risk for a wide variety of diseases. Identifying these associations and understanding their molecular mechanisms is ongoing and holds promise for the development of therapeutics. Find the latest research on HLA genetic variation here.

Super-resolution Microscopy

Super-resolution microscopy is the term commonly given to fluorescence microscopy techniques with resolutions that are not limited by the diffraction of light. Here are the latest discoveries pertaining to super-resolution microscopy.
