What is EB and S?

Osteomyelitis

The first day i reported to Ms. Teoh Sok Li, Head of Quality Assurance(QA) Department, she ordered me to assist a QA assisstant, named Yong. End of the day, I didn't do much but intro myself to other staffs in QA. So, it was an ice-breaking day!

Second day, there are chances for me to flip through some documents in QA office. From their daily laboratory card, I can clearly see that sensory assessment, physical test as well as microbe test are being run for certain products.

'EB' and 'S' which appear under microbe test catch my eyes. After verification, i got to know that EB stands for Enterobacteriaceae and S is Salmonella. EB are a large family of bacteria, including many of the more familiar pathogens, such as Salmonella and Escherichia coli. EB are rod-shaped, basically 1.5 micro meter in length. They are facultative anaerobes and possess Gram-negative stains.

Whereas Staphylococcus aureus is a sperical bacterium which cause a range of illnesses from minor skin infections, such as pimples, impetigo, boils, cellulitis folliculitis, furuncles, carbuncles, scalded skin syndrome and abscesses, to life-threatening diseases, such as pneumonia, meningitis, osteomyelitis endocarditis, Toxic shock syndrome (TSS), and septicemia. Illness cause by Staph aureus is usually associated with hygiene aspetc as they are frequently living on human's skin and in nose. About 20-30% of population are 'staph carrier'

Tropical fruit- Soursop.

Neighboor gave us 2 soursops where the auntie said it's not local but origin from Sabah. Mum stored in fridge for few days and its skin turns black.

Today, i peeled it off while it's cold. The flesh of the fruit consists of an edible white pulp and a core of undigestible black seeds. The flesh's texture is pudding-liked, white in color, and taste like sweet mango! Compared to dragon fruit which contains uncountable seeds, seeds of soursop are kind of frustrated because they are large in size! I cant digest but to spit them out.


After some research done, I had found out that soursop is native to Carribean, Central and South America, and is commonly grown in South-East Asia. It is adapted to areas of high humidity and relatively warm winters, temperatures below 5 °C will cause damage to leaves and small branches, and temperatures below 3 °C can be fatal.


Nutritionally, the fruit is high in carbohydrates, particularly fructose. The fruit also contains significant amounts of vitamin C, vitamin B1 and vitamin B2. People in Caribbean believe that laying the leaves of soursop on a bed below a person with a fever will break the fever by the next morning. Boiling the leaves and drinking as a tea are believed to induce sleep too!
