| |
| − | | |
| − | *Caused by ''Mycoplasma haemofelis ( ''until recently, known as'' Haemobartonella felis)
| |
| − | *Organism found on surface of erythrocytes
| |
| − | *Common in roaming tom-cats of 1-3 years old
| |
| − | *Possibly transmitted via bite wounds or arthropods
| |
| − | *Recoverd cats become carriers
| |
| − | | |
| − | *Clinical signs
| |
| − | **Peracute disease is associated with severe anaemia and immunosuppression, and can be rapidly fatal
| |
| − | **Fever, anaemia, depression, weakness and jaundice occur in the acute form
| |
| − | **Anaemia, lethargy and weight loss occur in the chronic form
| |
| − | **Recovery can occur with a regenerative bone marrow response
| |
| − | **Severe feline infectious anaemia may occur in the presence of feline leukaemia virus
| |
| − | | |
| − | *Diagnosis
| |
| − | **Organism intermittently seen on the surface of red blood cells in Giemsa-stained blood smears
| |
| − | **Immunofluorescence of blood smears
| |
| − | **Reduced packed cell volume; regenerative anaemia
| |
| − | | |
| − | *Treatment
| |
| − | **Doxycycline for 3 weeks early in the course of the disease
| |
| − | **Blood transfusion
| |
| − | **Flea control

| − | ===Canine haemobartonellosis===
| |
| − | | |
| − | *Dogs infected with ''Haemobartonella canis'' usually asymptomatic
| |
| − | *Acute haemolytic anaemia may occur in dogs after splenectomy, immunosuppressive drug therapy or immunosuppressive infections
| |
| − | | |
| − | | |
| − | ===Q fever===
| |
| − | | |
| − | *Caused by ''Coxiella burnetti''
| |
| − | *Influenza-like disease of humans in contact with farm animals
| |
| − | *Transmitted to humans by inhalation from parturient sheep, goats and cattle
| |
| − | *Organisms replicate in female genital tract and mammary glands of ruminants
| |
| − | *Shedding occurs in uterine discharges, foetal fluid and milk
| |
| − | *Infections in animals usually subclinical
| |
| − | *Sporadic abortions occur in sheep, goats, cattle, cats
| |
| − | *Infertility may result in ruminants, as well as placentitis or endometritis
| |
| − | *Hepatitis, myocarditis and interstitial pneumonia may occur in affected foetuses
| |
| − | *Diagnosis: MZN-stained smears of placental tissue and uterine discharges; immunofluorescence; PCR; culture; serology
| |
| − | *Control: disposal of infected placenta and separation of pregnant ruminants; inactivated vaccines
