Spotted Fever Rickettsiosis
Spotted fever rickettsiosis, also known as spotted fever group rickettsia (SFGR), is a group of infections that include Rocky Mountain spotted fever, Rickettsia parkeri rickettsiosis, Pacific Coast tick fever, and rickettsialpox Rickettsialpox is a mite-borne infectious illness caused by bacteria of the genus '' Rickettsia'' (''Rickettsia akari''). Physician Robert Huebner and self-trained entomologist Charles Pomerantz played major roles in identifying the cause of t .... The group of infections was created in 2010 as they are difficult to tell apart. References {{Tick-borne diseases Rickettsioses Bacterium-related cutaneous conditions Zoonoses Tick-borne diseases ...

Rocky Mountain Spotted Fever
Rocky Mountain spotted fever (RMSF) is a bacterial disease spread by ticks. It typically begins with a fever and headache, which is followed a few days later with the development of a rash. The rash is generally made up of small spots of bleeding and starts on the wrists and ankles. Other symptoms may include muscle pains and vomiting. Long-term complications following recovery may include hearing loss or loss of part of an arm or leg. The disease is caused by ''Rickettsia rickettsii'', a type of bacterium that is primarily spread to humans by American dog ticks, Rocky Mountain wood ticks, and brown dog ticks. Rarely the disease is spread by blood transfusions. Diagnosis in the early stages is difficult. A number of laboratory tests can confirm the diagnosis but treatment should be begun based on symptoms. It is within a group known as spotted fever rickettsiosis, together with ''Rickettsia parkeri'' rickettsiosis, Pacific Coast tick fever, and rickettsialpox. Treatment of ...

Rickettsia Parkeri Rickettsiosis
''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. ovale ...

Pacific Coast Tick Fever
Pacific Coast tick fever is an infection caused by ''Rickettsia philipii''. The disease is spread by the Pacific coast ticks. Symptoms may include an eschar. It is within a group known as spotted fever rickettsiosis together with Rickettsia parkeri rickettsiosis, Rocky Mountain spotted fever, and rickettsialpox Rickettsialpox is a mite-borne infectious illness caused by bacteria of the genus '' Rickettsia'' (''Rickettsia akari'').

Rickettsialpox
Rickettsialpox is a mite-borne infectious illness caused by bacteria of the genus ''Rickettsia'' (''Rickettsia akari''). Physician Robert Huebner and self-trained entomologist Charles Pomerantz played major roles in identifying the cause of the disease after an outbreak in 1946 in a New York City apartment complex, documented in "The Alerting of Mr. Pomerantz," an article by medical writer Berton Roueché. Although it is not transmitted by a tick (a characteristic of spotted fever), the bacterium is a part of the spotted fever group of ''Rickettsia'', and so this condition is often classified with that group. Signs and symptoms The first symptom is a bump formed by the bite, eventually resulting in a black, crusty scab. Many of the symptoms are flu-like including fever, chills, weakness and achy muscles but the most distinctive symptom is the rash that breaks out, spanning the infected person's entire body. Transmission The bacteria are originally found in mice and cause mites ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rickettsioses
A rickettsiosis is a disease caused by intracellular bacteria. Cause Rickettsioses can be divided into a spotted fever group (SPG) and typhus group (TG). In the past, rickettsioses were considered to be caused by species of Rickettsia. However, scrub typhus is still considered a rickettsiosis, even though the causative organism has been reclassified from ''Rickettsia tsutsugamushi'' to ''Orientia tsutsugamushi''.Examples of rickettsioses include typhus, both endemic and epidemic, Rocky Mountain spotted fever, and Rickettsialpox. Organisms involved include Rickettsia parkeri. Many new causative organisms have been identified in the last few decades. Most are in the genus ''Rickettsia'', but scrub typhus is in the genus ''Orientia''. Diagnosis No rapid laboratory tests are available to diagnose rickettsial diseases early in the course of illness, and serologic assays usually take 10–12 days to become positive. Research is indicating that swabs of eschars may be used for molecular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoonoses
A zoonosis (; plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite or prion) that has jumped from a non-human (usually a vertebrate) to a human. Typically, the first infected human transmits the infectious agent to at least one other human, who, in turn, infects others. Major modern diseases such as Ebola virus disease and salmonellosis are zoonoses. HIV was a zoonotic disease transmitted to humans in the early part of the 20th century, though it has now evolved into a separate human-only disease. Most strains of influenza that infect humans are human diseases, although many strains of bird flu and swine flu are zoonoses; these viruses occasionally recombine with human strains of the flu and can cause pandemics such as the 1918 Spanish flu or the 2009 swine flu. ''Taenia solium'' infection is one of the neglected tropical diseases with public health and veterinary concern in ende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
