1 Haemophilia A is a recessive X-linked genetic disorder involving a lack of functional clotting Factor VIII and represents 80% of haemophilia cases. 2  Haemophilia B is a recessive X-linked genetic disorder involving a lack of functional clotting Factor IX.
There are other biochemical tests that help to identify Serratia marcescens in the lab. It is negative for the methyl red test due to their production of 2, 3 - butanediol and ethanol, but positive for the Voges-Proskauer test, which shows an organismâs ability to convert pyruvate to acetoin [4].ydrolysis of casein is not a common trait and is therefore useful in the differentiation of Serratia marcescens from the 438 strains of Enterobacteriaceae and Pseudomonadaceae families [12]. Serratia marcescens has the reproducible capability to break down casein producing a clearing on milk agar plates.
Serratia Marcescens symptoms are very similar regardless of what disease the bacterium causes. Some common diseases include Serratia Sepsis, Serratia plymuthica, Serratia liquefaciens, Serratia rubidaea, Serratia odorifera, and Serratia fonticola.remature children and infants with an existing diagnosis of sepsis, or after experiencing some kind of head surgery or neurosurgery may develop meningitis caused by Serratia Marcescens with symptoms including headache, fever, vomiting, stupor and may result in coma.
