Because each possibility is equally likely, genotypic ratios can be determined from a Punnett square. If the pattern of inheritance (dominant or recessive) is known, the phenotypic ratios can be inferred as well. For a monohybrid cross of two true-breeding parents, each parent contributes one type of allele. In this case, only one genotype is possible.
Occult (hidden) bacteremia is the presence of bacteria in the bloodstream of a child who has a fever but who looks well and has no obvious source of infection. Most commonly, occult bacteremia is caused by Streptococcus pneumoniae bacteria. Typically, children have no symptoms other than fever.
For the systemic immune response to bacterial infection in the blood, see sepsis. Bacteremia (also bacteraemia) is the presence of bacteria in the blood. Blood is normally a sterile environment, so the detection of bacteria in the blood (most commonly accomplished by blood cultures) is always abnormal.acteremia is different from sepsis (so-called blood poisoning or toxemia), which is a condition where bacteremia is associated with an inflammatory response from the body (causing systemic inflammatory response syndrome, characterised by rapid breathing, low blood pressure, fever, etc.).
