INTRODUCTION

+ TYPHOID FEVER: A RACE AGAINST TIME

Constantly the body is trying to protect himself of the pathogenic microorganism that can affect significantly.

+

TYPHOID FEVER: A RACE AGAINST

TIME

Neutrophils and monocytes enclose the bacteria to form abscess. But some of them can escape and continue infecting.

+TYPHOID FEVER: A RACE

AGAINST TIME

Although the immune cells kill a lot of bacteria Salmonella, there are others that evade that abscess and escape, guaranteed his survival and his replicates in all the body.

+ TYPHOID FEVER: A RACE AGAINST TIME

+STUDENT OBSERVATION

It is important to further scientific development in these areas to achieve eradicate Salmonella, who generate resistance even faster than the creation of new antibiotics.

+Steps leading to necrotizing fasciitis revealed, opening

way to possible new treatments for bacterial

infections

Group A Streptococcus (GAS) or S. Pyogenes, is a silent bacteria that colonize the body without produce any symptoms and can be mortal in a lot of cases such as toxic shock syndrome and streptococcal necrotizing fasciitis (flesh-eating disease)

+ STEPS LEADING TO NECROTIZING FASCIITIS REVEALED, OPENING WAY TO

POSSIBLE NEW TREATMENTS FOR BACTERIAL INFECTIONS

Once the bacteria enter to the cell, liberates two streptolysins that inhibit the synthesis of proteins in the cytoplasm.

+ STEPS LEADING TO NECROTIZING FASCIITIS REVEALED, OPENING WAY TO

POSSIBLE NEW TREATMENTS FOR BACTERIAL INFECTIONS

The human cells increases the production of the amino acid asparagine as a method of defence that alters gene expression of GAS and increases his virulence.

ASPARAGINE

+STEPS LEADING TO

NECROTIZING FASCIITIS REVEALED, OPENING

WAY TO POSSIBLE NEW TREATMENTS FOR

BACTERIAL INFECTIONS

Asparaginase degrades asparagina. Thats why they use it to reduce the growth of GAS in human blood and mouse models of human infection.

+

Asparaginase has never before used to treat GAS infections. Knowing the metabolic changes occurring between the pathogen and its host´s infection can lead to develop a few of effective treatment against infection diseases.

STUDENT OBSERVATION

+MEDICAL UTILITY

The doctors, food distributors, among many other companies, are straining to maintain the necessary hygiene for disease control in clients, workers or patients.

+MEDICAL UTILITY

As health workers, we should alert people about this kind of diseases that are so contagious and how they can prevent them.

+

Some examples can be taking care of his own body, washing hands with a very good disinfectant and not consuming food which has expired date of caducity, also prevent the transmission, trying to cover the mouth when sneezing, or not share stuff that can have contact with fluids or blood of our body.

MEDICAL UTILITY

+

With the development of the studies about the virulence of those bacterias and how can they affect us, we can investigate more about a lot treatments that can helps to control the early effects that cause a lot of damage even if we don't feel any symptom, reducing the annual number of deaths.
