  • Skin and Soft Tissue Infections S. aureus causes a variety of cutaneous infections. Common predisposing factors include skin disease, skin damage (e.g., insect bites, minor trauma), injections (e.g., in diabetes, injection drug use), and poor personal hygiene. These infections are characterized by the formation of pus-containing blisters, which often begin in hair follicles and spread to adjoining tissues. Folliculitis is a superficial infection that involves the hair follicle, with a central area of purulence (pus) surrounded by induration and erythema.

  • Several species of flies are found commonly in houses. Some of them so closely resemble the true house fly that it requires very careful observation to distinguish them from it. One of these is the biting stable fly[2] (fig. 1). It occurs frequently in houses and differs from the house fly in the important particular that its mouth parts are formed for piercing the skin. This fly is so often mistaken for the house fly that most people think that the house fly can bite.

  • Tularemia is a zoonosis caused by Francisella tularensis. Humans of any age, sex, or race are universally susceptible to this systemic infection. Tularemia is primarily a disease of wild animals and persists in contaminated environments, ectoparasites, and animal carriers. Human infection is incidental and usually results from interaction with biting or blood-sucking insects, contact with wild or domestic animals, ingestion of contaminated water or food, or inhalation of infective aerosols.

  • The resettlement of humans on earth has never taken place as rapidly as it is doing now. As little as 1% of the earth’s total land mass is used as urban centres (cities) and these cities, astoundingly, carry 50% of the world’s population. Urban centres are extremely well suited to a group of insects which have associated their lives with humans and their activities. These urban insects cause pain, annoyance, emotional distress, disability and damage as a result of bites, stings and physical reactions, in addition to a plethora of diseases and other damage.
