PREVALENCE AND ANTIMICROBIAL SUSCEPTIBILITY OF GRAM NEGATIVE BACTERIA IN THE URINE OF UNIVERSITY STUDENTS
ABSTRACT
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 56.70% and 43.30% respectively under the ages of 18-25yrs.Escherichia coli was the most predominant. The isolates were very sensitive to Gentamycin, Nitrofurantoin and Ofloxacin which were the (most sensitive) and the most resistant were Tetracycline, Cortrimozol, Cephalexin and Ampicillin. Therefore, Nitrofurantoin, Gentamycin, Ofloxacin were strongly recommended for the treatment of UTI as indicated in the study.
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
HERE IS WHAT OUR HAPPY CLIENTS ARE SAYING
I actually googled and saw about projectmaster.com.ng, copied the number and contacted them through WhatsApp to ask for the availability of the material and to my luck they have it. So there was a delay with the project due to the covid19 pandemic. I was really scared before making the payment cause I’ve been scammed twice, they attended so well to me and that made me trust the process and made the payment and provided them with proof, I got my material in less than 10minutes.
I received excellent customer support, and quickly. Thank you so much!
I love your service! I would recommend projectmaster.com.ng to anyone. What a great find!
I am aware of online scam but because of the hectic nature of writing project, I decided to try sourcing for help online and to my surprise, projectmaster.com.ng gave complete project in less than 5 minutes. I could not believe it sincerely. Thank you so much guys.
