COCCINELLA BURNETII SKIN
More rarely, it can cause yellowing of the skin and the whites of the eyes (jaundice). Hepatitis may cause abnormal enlargement of the liver (hepatomegaly). Pneumonia is often mild but can potentially progress to cause acute respiratory distress syndrome (ARDS). Pneumonia and inflammation of the liver (hepatitis) are commonly associated with acute Q fever. Many people also suffer from small areas of inflammation (granuloma). Additional nonspecific symptoms can potentially occur including cough, chest pain, sore throat, skin rash or gastrointestinal symptoms. Acute Q fever is characterized by flu-like symptoms such as high fevers, chills, muscle pain (myalgia), muscle weakness, fatigue and headaches. The acute form of Q fever starts approximately two to three weeks after exposure to the bacterium. Researchers believe that a variety of factors may influence the severity of Q fever including age, gender and a person’s general health, including pre-existing medical conditions (e.g., heart disease). Infection can result in no apparent symptoms (asymptomatic) an acute form of disease characterized by a flu-like illness that either goes away on its own (self-limited) or causes more serious symptoms or a chronic form that can be associated with serious complications. The symptoms of Q fever can vary dramatically from one person to another. burnetti was included on the list of possible bacteriological weapons. Since infection can occur because of airborne transmission and the bacterium is very resistant to environmental conditions such heat and pressure, C. People of all ages are susceptible to Q fever. Treatment for chronic Q fever is more complex and depends on an individual’s presenting symptoms. Acute Q fever is treated with antibiotics. Infections that do not cause outward symptoms (subclinical) or no symptoms (asymptomatic) are also common. Progression of Q fever from acute infection to chronic fever occurs in less than 5% of patients. Q fever causes highly variable symptoms ranging from acute (often self-limited) infection to fatal chronic infection. Other forms of transmission are rare but include tick bites and human to human transmission. Farm workers, especially those who work with animals, people who work in slaughterhouses and veterinarians are especially vulnerable to this disease. burnetii is spread mainly by breathing contaminated air or eating or drinking contaminated food. Animals such as cattle, sheep and goats are common bacterial hosts for this bacterium. Q fever is an infectious disease that is spread by the inhalation or ingestion of a bacterium known as Coxiella burnetii, which belongs to the order of Legionellales.

Infection during pregnancy has a specific clinical presentation (mostly asymptomatic), and may result in obstetric and fetal complications. Symptoms and complications are different between acute infection (i.e., a self-limiting febrile illness with varying degrees of pneumonia and hepatitis) and persistent focalised infections (e.g., endocarditis, vascular infection, osteoarticular infection, lymphadenitis). However, C burnetii small cell variant (pseudospores) can spread by air up to 10 kilometres from the source of infection so that exposure history is frequently lacking.
Many species of mammals, birds, and ticks are reservoirs of the bacterium, and the disease is spread globally through close contact with wild or domestic animals, especially their products of parturition, and also their urine, faeces, or milk.
