Plague-infested animals are found in many other countries as well, especially in developing countries where health controls are not effective. Animals that commonly carry plague bacteria are largely rodents and Leporidae, but carnivores sometimes also become infected by their prey. Prey animals are not immune to the disease, and outbreaks of various strains of plague, such as sylvatic plague, have on occasion devastated populations of black-tailed prairie dogs and black-footed ferrets.Plague has been active in black-tailed prairie dog populations since the 1960s. In the United States outbreaks only occur in the western States and they are devastating, with mortality rates near 100% because the animals have no immunity to the plague. Survivors are the ones that happened not to become infected and colonies that recover from a plague outbreak remain at risk.Because black-footed ferrets prey on black-tailed prairie dogs, wild ferret populations also fall victim to sylvatic plague. An outbreak can kill nearly 100% of ferrets in a population, and surviving ferrets commonly face starvation because the prairie dogs are their main prey. Spray-and-vaccinate campaigns have aimed at preventing the spread of the plague among these animals.Similar septicemic problems occurs in many countries across the world, especially in developing countries where spending on health systems is very low and health controls are not effective. == References ==
There are several types, including:
X-linked chronic granulomatous disease (CGD)
autosomal recessive cytochrome b-negative CGD
autosomal recessive cytochrome b-positive CGD type I
autosomal recessive cytochrome b-positive CGD type II
atypical granulomatous disease

Treatment
Management of chronic granulomatous disease revolves around two goals: 1) diagnose the disease early so that antibiotic prophylaxis can be given to keep an infection from occurring, and 2) educate the patient about his or her condition so that prompt treatment can be given if an infection occurs. Antibiotics
Physicians often prescribe the antibiotic trimethoprim-sulfamethoxazole to prevent bacterial infections. This drug also has the benefit of sparing the normal bacteria of the digestive tract. Fungal infection is commonly prevented with itraconazole, although a newer drug of the same type called voriconazole may be more effective. The use of this drug for this purpose is still under scientific investigation. Immunomodulation
Interferon, in the form of interferon gamma-1b (Actimmune) is approved by the Food and Drug Administration for the prevention of infection in CGD. It has been shown to reduce infections in CGD patients by 70% and to decrease their severity. Although its exact mechanism is still not entirely understood, it has the ability to give CGD patients more immune function and therefore, greater ability to fight off infections. This therapy has been the standard treatment for CGD for several years. Hematopoietic stem cell transplantation (HSCT)
Hematopoietic stem cell transplantation from a matched donor is curative although not without significant risk. Prognosis
There are currently no studies detailing the long term outcome of chronic granulomatous disease with modern treatment.
