BMS 424 Chapter 1 DNA‚ RNA‚ Historical Experiments & Structures Frederick Griffith Experiments with Streptococcus pneumoniae S. pneumoniae comes in two strains‚ smooth and rough strains S Smooth : Secrete a polysaccharide capsule; Protects bacterium from immune system of hosts; Produce smooth colonies on solid media. R Rough : Unable to form capsule; Produce colonies with a rough appearance. Griffith conducted experiments in 1928 using two strains of S. pneumoniae: type IIIS and type IIR :

History of tattoos Did you know that the first sign of tattoos were discovered on the “Iceman” dating back over five thousand centuries? These tattoos were simple lines and dots‚ but the significance is unknown. The word tattoo is said to have two major derivations- from the Polynesian word ‘ta’ which means striking something and the Tahitian word ‘tatau’ which means ‘to mark something’. After reading this‚ one will know the background and history of tattoos‚ the evolution of the equipment used

INTRODUCTION Pneumonia is an inflammation of the lungs caused by an infection. It is also called Pneumonitis or Bronchopneumonia. Pneumonia can be a serious threat to our health. Although pneumonia is a special concern for older adults and those with chronic illnesses‚ it can also strike young‚ healthy people as well. It is a common illness that affects thousands of people each year in the Philippines‚ thus‚ it remains an important cause of morbidity and mortality in the country. There are many

I. INTRODUCTION Pneumonia is an inflammation of the lung parenchyma caused by various microorganisms‚ including bacteria‚ mycobacteria‚ fungi‚ and viruses. Pneumonias are classified as community- acquired pneumonia (CAP)‚ hospital-acquired (nosocomial) pneumonia (HAP)‚ pneumonia in the immunocompromised host‚ and aspiration pneumonia. There is overlap in how specific pneumonias are classified‚ because they may occur in differing settings. Those at risk for pneumonia often have chronic underlying

3.2. Screening and optimization of the most effective factors on protease production by S. marasensis 3.2.1. One-facto-at-a-time Since protease production and growth of S. marasensis SR-081 Halo was affected by nutritional factors and culture conditions‚ the medium was initially optimized by one-factor-at-a-time method. Maximum growth of the strain and protease production was observed at pH 7‒8 (Fig. 2a and 2b)‚ 40 ºC (Fig. 2c and 2d)‚ and inoculum size of 10% (v/v) (Fig. S5a)‚ that to reduce the
