| − | ==Introduction==
| |
| − | Aelurostrongylosis is the disease caused by the cat lungworm [[Aelurostrongylus abstrusus]], which is found in many parts of Europe, the USA and Australia.
| |
| − |
| |
| − | ==Clinical signs==
| |
| − | The disease is often '''asymptomatic''', and serious respiratory problems usually occur due to a deficient immunity, following FIV infection for example.
| |
| − |
| |
| − | Respiratory signs are usually '''progressive and worstening'''. Heavy infections can cause '''severe bronchopneumonia''', with cats presenting with '''open-mouth breathing''' and abdominal effort.
| |
| − |
| |
| − | There might also be '''coughing and sneezing''' and systemic signs such as '''anorexia, lethargy and wasting'''.
| |
| − |
| |
| − | ==Diagnosis==
| |
| − | '''Radiography''' may reveal a diffuse interstitial pattern with focal peribronchial densities. An alveolar pattern may appear in severe cases.
| |
| − |
| |
| − | '''Bronchial lavage''' may reveal characteristic coiled larvae with an undulating tail and spine and eosinophilic inflammation.
| |
| − |
| |
| − | '''Haematology''' may reveal eosinophilia.
| |
| − |
| |
| − | '''Post mortem examination''' may reveal greenish nodules in the lungs.
| |
| − |
| |
| − | Microscopically, eggs and larvae in the alveolar spaces cause a foreign body type reaction (surrounded by mononuclear cells and giant cells). There is submucosal gland hypertrophy and smooth muscle hypertrophy in airway and vessel walls.
| |
| − |
| |
| − | ==Treatment and prevention==
| |
| − | Treatment is difficult and '''not often necessary''' unless the cat is showing clinical signs, as the disease is usually self-limiting.
| |
| − |
| |
| − | '''Fenbendazole''' for 21 consecutive days is usually effective. Ivermectin has also been used in some cases.
| |
| − |
| |
| − | '''Control''' is by prevention of hunting by cats.
