Question

s Streptococcus pneumoniae aerobic, facultative anaerobic, or anaerobic? I've been finding mixed answers in every source I have checked.

Answer 1

*Is

Answer 2

most of streptococci that cause human infection are facultative anaerobes although some are strict anaerobes.strptococcus pneumonia belongs to alpha hemolytic str.which produce a greenis zone of partial hemolysis.

Answer 3

Streptococcus pneumoniae is a fermentative aerotolerant anaerobe.

Answer 4

What is your source? I'm doing a report and I need an academic/scholarly source

Answer 5

harrisons principles of internal medicine
ananthanarayanan and jayaram panicker textbook of microbiology for medical students

Answer 6

which sources did u check?

Answer 7

Oh okay. I am doing a report for Microbiology and was just using government and university sites. I do not have access to those books.

Answer 8

n http://textbookofbacteriology.net/S.pneumoniae.html
this textbook is on line

Answer 9

That is the one I originally found. This website says differently : http://www.atsu.edu/faculty/chamberlain/Website/studio.htm

Answer 10

i dont know it is aerotolerant anaerobe meaning it can grow in aerobic media as well .u might as well ask chamberlain.....

Answer 11

The following report compares the results of aerobic and anaerobic cultivation for the primary isolation of Streptococcus pneumoniae (the pneumococcus) from the respiratory tract of children. Of 414 specimens of respiratory tract secretions cultured, 65 (15-7%) yielded pneumococci; 31 (47-7%) grew both aerobically and anaerobically, but 34 (52-3%) strains were isolated only from the anaerobic culture. Pneumococci cultured anaerobically with added carbon dioxide characteristically produce large mucoid colonies which are more easily distinguished than the 'normal' colonies commonly seen in the mixed flora isolated from respiratory sites. This advantage justifies the inclusion of anaerobic culture when attempting to isolate Str. pneumoniae from clinical material.
which means its more of an anaerobe thAn an aerbe

Answer 12

I understand. That makes more sense now.
