In blood culturing, the machine alerts us when the level of carbon dioxide increases. This indicates that there is most probably multiplication of micro organisms in a particular blood culture bottle.
Suppose the patient's specimen revealed scanty GPC in chains.
Could you offer a reason why a Gram done on the blood culture bottle may show no organisms. Even though the machine sounded an alert.
The acid fast smear shows AFB. Growth on selective agar is negative after 6 weeks.
Suggest a few reasons why this may be.
