Flea-borne Spotted Fever

	Flea-borne Spotted Fever Flea-borne spotted fever or California pseudotyphus is a condition characterized by a rash of maculopapules or furuncle A boil, also called a furuncle, is a deep folliculitis, which is an infection of the hair follicle. It is most commonly caused by infection by the bacterium ''Staphylococcus aureus'', resulting in a painful swollen area on the skin caused by an ...s. It is caused by '' Rickettsia felis''.

	Infectious Disease (medical Specialty) Infectious diseases or ID, also known as infectiology, is a medical specialty dealing with the diagnosis and treatment of infections. An infectious diseases specialist's practice consists of managing nosocomial ( healthcare-acquired) infections or community-acquired infections and is historically associated with hygiene, epidemiology, clinical microbiology, travel medicine and tropical medicine. Scope Infectious diseases specialists typically serve as consultants to other physicians in cases of complex infections, and often manage patients with HIV/AIDS and other forms of immunodeficiency. Although many common infections are treated by physicians without formal expertise in infectious diseases, specialists may be consulted for cases where an infection is difficult to diagnose or manage. They may also be asked to help determine the cause of a fever of unknown origin. Specialists in infectious diseases can practice both in hospitals (inpatient) and clinics (outpatient). In hospit ...

	Furuncle A boil, also called a furuncle, is a deep folliculitis, which is an infection of the hair follicle. It is most commonly caused by infection by the bacterium ''Staphylococcus aureus'', resulting in a painful swollen area on the skin caused by an accumulation of pus and dead tissue. Boils which are expanded are basically pus-filled nodules. Individual boils clustered together are called carbuncles. Most human infections are caused by coagulase-positive ''S. aureus'' strains, notable for the bacteria's ability to produce coagulase, an enzyme that can clot blood. Almost any organ system can be infected by ''S. aureus''. Signs and symptoms Boils are bumpy, red, pus-filled lumps around a hair follicle that are tender, warm, and painful. They range from pea-sized to golf ball-sized. A yellow or white point at the center of the lump can be seen when the boil is ready to drain or discharge pus. In a severe infection, an individual may experience fever, swollen lymph nodes, and fatigu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Rickettsia Felis ''Rickettsia felis'' is a species of bacterium, the pathogen that causes cat-flea typhus in humans, also known as flea-borne spotted fever. ''Rickettsia felis'' also is regarded as the causative organism of many cases of illnesses generally classed as fevers of unknown origin in humans in Africa. Transmission and concerns Until recently, fleas have been the recognised vectors of ''Rickettsia felis'' and it is present in cat flea populations of North and South America, Southern Europe, Africa, Thailand and Australia. Human infection usually results from flea feces coming into contact with scratched or broken skin. More recently, some authorities have published increasing concerns about the role of more and more species of arthropod vectors of this organism; ''Rickettsia felis'' has by now been detected in many arthropods in the wild, including various species of mites, ticks, blood-sucking bugs in the genus ''Cimex'', sucking lice, flea species of various types, both free-living ...

	American Tick Bite Fever ''Rickettsia parkeri'' (abbreviated ''R. parkeri'') is a gram-negative intracellular bacterium. The organism is found in the Western Hemisphere and is transmitted via the bite of hard ticks of the genus ''Amblyomma''. ''R. parkeri'' causes mild spotted fever disease in humans, whose most common signs and symptoms are fever, an eschar at the site of tick attachment, rash, headache, and muscle aches. Doxycycline is the most common drug used to reduce the symptoms associated with disease. Biology ''R. parkeri'' is classified in the spotted fever group of the genus ''Rickettsia''. Genetically, its close relatives include '' R. africae'', '' R. sibirica'', '' R. conorii'', '' R. rickettsii'', '' R. peacockii'', and '' R. honei''. The organism has been isolated from numerous species of ticks in the genus ''Amblyomma'': '' A. americanum'' in the United States; ''A. aureolatum'' in Brazil; '' A. maculatum'' in Mexico, Peru, and the United States; '' A. nodosum'' in Brazil; ''A. oval ...

picture info	List Of Cutaneous Conditions Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying meso ...
