A Study of Gram Stained Specimens Obtained from Pediatric Inpatients of Kawasaki Medical School Hospital – Achievements from an elementary research experiment by a 2nd year medical student
This study was designed as an elementary medical research experiment course for a 2nd year medical student. All Gram stained specimens deriving from upper respiratory tract specimens collected from pediatric inpatients admitted to the pediatric ward of our hospital during 2018 October 1st through 31st were examined; the result was assessed as to whether or not it was in concordance with past reports or not. Gram-negative cocci (Moraxella catarrhalis -like), Gram-negative rods (Haemophilus influenzae -like), and Gram-positive diplococci (Streptococcus pneumoniae -like) were frequently encountered in this order; these three most encountered species were in concordance with previous reports, whereas their order was not. This difference in the order of frequency might be attributed to the legislation of vaccination against Haemophilus influenzae type b and Streptococcus pneumoniae .
