Nature has provided us with infections - acute and chronic - and these infections have both harmful and beneficial effects on the human system. Worldwide, a number of chronic infections are associated with a risk of cancer, but it is also known that cancer regresses when associated with acute infections such as bacterial, viral, fungal, protozoal, etc. Acute infections are known to cure chronic...

I read with great interest in a recent issue of CHEST (April 2014) the article by Khemasuwan et al, 1 who provided a comprehensive review of helminthic and protozoal infestations of the respiratory system. Regarding the protozoal infestations, however, I think the authors have omitted a group of fl agellated protists, the parabasalids, some of which are well-known protozoa and others of which a...

Parasitic protozoan infections represent a major health burden in the developing world and contribute significantly to morbidity and mortality. These infections are often associated with considerable variability in clinical presentation. An emerging body of work suggests that the intestinal microbiota may help to explain some of these differences in disease expression. The objective of this min...

After a useful account of sigmoidoscopy, a short historical survey and a discussion of their geographical distribution, the bacillary, protozoal, and helminthic dysenteries are described in considerable detail. Following this well documented and balanced survey, it is disappointing to have paratyphoid infections and food poisoning dismissed in four pages, especially as it is admitted that parat...

The brunt of the human immunodeficiency virus (HIV) pandemic has been borne disproportionately by resource-poor regions of the world, where tropical infectious diseases continue to hold greatest sway. As a result, our understanding of the epidemiological, biological, and clinical interactions between HIV and tropical pathogens has lagged, compared with our understanding of the interactions betw...

Diarrhoea is one of the top five causes death among paediatric and geriatric population in India. Bacterial, viral protozoal pathogens contaminating food water, or even opportunistic commensal microbes can lead to diarrhoeal infections. A number anti- infective antiparasitic agents are available for treating these However, they come along with their distinct side effects. Alternative systems me...
