Next, eggs hatch in the intestine of the definitive host and circulate in the bloodstream until they reach suitable organs. Symptoms and diagnosis
The symptoms for coenurosis vary depending on where the cyst is located. Prevention and treatment
In sheep, the usual treatment is surgical trepanation to remove the brain cyst, one of the few economically viable surgeries in farm animals. The site of the cyst can usually be estimated based on the neurological symptoms and skull thinning. Treated sheep typically regain sufficient function to rejoin the flock and necropsy indicates that the site of the cyst collapses and scars, relieving pressure on the brain.In the rare cases where a human is infected, both surgical and pharmaceutical treatments are available. Since the disease is so uncommon in humans, no vaccine has been developed for it. Epidemiology
T. multiceps is commonly found in France, England, Brazil, Africa, and the United States. T. serialis is found in Canada and the United States
T. brauni is found in North America, Rwanda, and the Republic of Congo
T. glomerata is found in Nigeria and the Republic of Congo

Hosts
The definitive hosts for coenurosis are dogs, foxes, and other canids. The intermediate hosts for coenurosis can vary depending on the Taenia spp. In T. multiceps, sheep are the intermediate hosts, but goats, cattle, horses, and antelopes are also common hosts. T. multiceps can affect any tissue, but it normally targets the brain in animal hosts. In T. serialis, rabbits and rodents are the intermediate hosts. T. serialis commonly targets subcutaneous and intramuscular tissue.
Pneumocystosis is a fungal infection that most often presents as Pneumocystis pneumonia in people with HIV/AIDS or poor immunity. It usually causes cough, difficulty breathing and fever, and can lead to respiratory failure. Involvement outside the lungs is rare but, can occur as a disseminated type affecting lymph nodes, spleen, liver, bone marrow, eyes, kidneys, thyroid, gastrointestinal tract or other organs. If occurring in the skin, it usually presents as nodular growths in the ear canals or underarms.It is caused by Pneumocystis jirovecii, a fungus which is usually breathed in and found in the lungs of healthy people without causing disease, until the persons immune system becomes weakened.Diagnosis is by identifying the organism from a sample of fluid from affected lungs or a biopsy. Prevention in high risk people, and treatment in those affected is usually with trimethoprim/sulfamethoxazole (co-trimoxazole).The prevalence is unknown. Less than 3% of cases do not involve the lungs. The first cases of pneumocystosis affecting lungs were described in premature infants in Europe following the Second World War. Signs and symptoms
Pneumocystosis is generally an infection in the lungs. Involvement outside the lungs is rare but, can occur as a disseminated type affecting lymph nodes, bone marrow, liver or spleen. It may also affect skin, eyes, kidneys, thyroid, heart, adrenals and gastrointestinal tract. Lungs
When the lungs are affected there is usually a dry cough, difficulty breathing and fever, usually present for longer than four weeks. There may be chest pain, shivering or tiredness. The oxygen saturation is low.
