II- Stage of acute abscess

 (After about 1-2 weeks)
lung abscessIt is manifested with fever, toxaemia then the patient gets a severe attack of cough with expectoration of thick mucus plug followed by large foited sputum due to growth of anaerobes. This is usually followed by drop of fever & improvement of general condition .
