CHAPTER ONE
INTRODUCTION
Gram negative bacteria are bacteria that do not retain their crystal violet dye in the gram staining protocol. They are differentiated by their cell wall structure. The following characteristics are displayed by gram negative bacteria as follows
Cytoplasmic membrane
Thin peptidoglycan layer(much thinner than gram positive)
Outer membrane containing lipopolysaccharide outside the peptidoglycan layer
Porin exists in the outer membrane, which acts like pores
There is a space between the layer of peptidoglycan and the secondary cell membrane, called the periplasmic space
If present, flagella have four (4) supporting rings instead of two
No techoic acid or lipopolysaccharide

ABSRACT - [ Total Page(s): 1 ]In order to access the prevalence and sensitivity pattern of urinary pathogens, 60 midstream urine samples from students of Caritas University were investigated using cultural methods. Samples were examined microscopically and cultured in blood agar and Macckonkey agar. Disk diffusion method was used for antibiotic testing. Of the 60 urine samples 48 yielded significant growth with a prevalence rate of 80%. It was observed that females were more infected than the males with a prevalence rate of ... Continue reading---
