Unimicrobial appendicitis due to non-vaccine serotype of streptococcus pneumoniae: Implications for and management and prevention. Indian Journal of Medical Microbiology. 2001 Apr-Jun; 19(2): 59-61http://imsear.searo.who.int/handle/123456789/53897The aetiology of appendicitis is usually polymicrobial. We report a rare case of appendicitis caused by Streptococcus pneumoniae as the only causative organism. The case assumes significance because it occurs in the absence of any predisposing factor for invasive pneumococcal infection, it is unimicrobial, it may lead to the misdiagnosis of primary peritonitis due to pneumococcus, and it undermines the efficacy of polyvalent pneumococcal vaccine.engJournal Article
