Community Acquired Pneumonia (CAP) is the most common respiratory tract infection in day to day practice. The knowledge of organism commonly causative of CAP helps in early empirical treatment initiation.
To study the microbiological profile of patients with community acquired pneumonia and to study drug sensitivity pattern.
Hospital based cross sectional study among 100 patients with CAP was conducted in a tertiary care hospital of Southern India. Sputum culture showed that out of 100 patients 39 had an identifiable etiology with 12 patients having evidence of mixed infection.
Micro-organisms isolated in sputum culture were Streptococcus pneumoniae (31%) followed by, Pseudomonas pyogens (15%), Klebsiella pneumoniae (13%). AFB smear was found to be positive in 6 patients. Organisms were found to be sensitive for piperacillin plus tazobactum (41%), aminoglycocides (amikacin-46%, gentamicin-31%), third generation cephalosporins (Cefotaxim-36%, Ceftriaxone-18%) and macrolides (Erythromicin-31%, Azithromycin-18%). Sensitivity to chloramphenicol was observed in 31% sputum culture positive patients. Ciprofloxacin sensitivity was seen among 49%.
Most of the organisms were found to be sensitive to monotherapy with extended spectrum beta lactamases, third generation cephalosporins, fluroquinolones, macrolides.
社区获得性肺炎(CAP)是日常医疗实践中最常见的呼吸道感染。了解CAP常见的致病微生物有助于尽早开始经验性治疗。
研究社区获得性肺炎患者的微生物学特征并研究药敏模式。
在印度南部一家三级护理医院对100例CAP患者进行了基于医院的横断面研究。痰培养显示,100例患者中有39例有可确定的病因,12例有混合感染的证据。
痰培养分离出的微生物依次为肺炎链球菌(31%)、化脓性假单胞菌(15%)、肺炎克雷伯菌(13%)。6例患者抗酸杆菌涂片呈阳性。发现微生物对哌拉西林加他唑巴坦(41%)、氨基糖苷类(阿米卡星-46%、庆大霉素-31%)、第三代头孢菌素(头孢噻肟-36%、头孢曲松-18%)和大环内酯类(红霉素-31%、阿奇霉素-18%)敏感。31%痰培养阳性患者对氯霉素敏感。49%的患者对环丙沙星敏感。
大多数微生物对广谱β-内酰胺酶、第三代头孢菌素、氟喹诺酮类、大环内酯类单药治疗敏感。
