Role of the Microbiology Laboratory in Infection Control
GUIDE TO INFECTION CONTROL IN THE HOSPITAL CHAPTER 3: Role of the Microbiology Laboratory in Infection Control Author Mohamed Benbachir, PhD Chapter Editor Gonzalo Bearman MD, MPH, FACP, FSHEA, FIDSA Topic Outline Key Issues Known Facts Suggested Practice Suggested Practice in Under-Resourced Settings Summary References Chapter last updated: January, 2018 KEY ISSUES The microbiology laboratory plays an important role in the surveillance, treatment, control and prevention oF nosocomial inFections. The microbiologist is a permanent and active member oF the infection control committee (ICC) and the antimicrobial stewardship group (ASG). Since most of the inFection control and antimicrobial stewardship programs rely on microbiological results, quality assurance is an important issue. KNOWN FACTS The microbiologist is a daily privileged interlocutor oF the infection control team (inFection control doctor and inFection control nurse) and the antimicrobial stewardship working group. The First task oF the microbiology laboratory is to accurately, consistently and rapidly identiFy the responsible agents to species level and identify their antimicrobial resistance patterns. Traditional microbiologic methods remain suboptimal in providing rapid identification and susceptibility testing. There is a growing need for more rapid and reliable laboratory results. Important progress made in the fields of instruments, reagents and techniques have made it easier to adapt to the important changes oF the clinical microbiology context e.g. increasing use of microbiology tests, shortage of qualiFied personnel. There is also a growing demand For quality in clinical laboratories and more and more countries are elaborating national regulations. 1 The microbiology processes are becoming increasingly more complex. InFormatics are playing an increasing role in the improvement oF these processes in terms oF workFlow, timeliness and cost.

Paper 1 Medicine Key topics 1 and 2 (1250-1500, 1500-1700) Year 11 GCSE History Paper 1 – Medicine Information booklet Medieval Renaissance 1250-1500 1500-1750 Enlightenment Modern 1900-present 1700-1900 Case study: WW1 1 Paper 1 Medicine Key topics 1 and 2 (1250-1500, 1500-1700) Key topic 1.1 – Causes of disease 1250-1500 At this time there were four main ideas to explain why someone might become ill. Religious reasons - The Church was very powerful at this time. People would attend church 2/3 times a week and nuns and monks would care for people if they became ill. The Church told people that the Devil could infect people with disease and the only way to get better was to pray to God. The Church also told people that God could give you a disease to test your faith in him or sometimes send a great plague to punish people for their sins. People had so much belief in the Church no-one questioned the power of the Church and many people had believed this explanation of illness for over 1,000 years. Astrology -After so many people in Britain died during the Black Death (1348-49) people began to look for new ways to explain why they became sick. At this time doctors were called physicians. They would check someone’s urine and judge if you were ill based on its colour. They also believed they could work out why disease you had by looking at where the planets were when you were born.

Early History of Infectious Disease 
© Jones and Bartlett Publishers. NOT FOR SALE OR DISTRIBUTION CHAPTER ONE EARLY HISTORY OF INFECTIOUS 1 DISEASE Kenrad E. Nelson, Carolyn F. Williams Epidemics of infectious diseases have been documented throughout history. In ancient Greece and Egypt accounts describe epidemics of smallpox, leprosy, tuberculosis, meningococcal infections, and diphtheria.1 The morbidity and mortality of infectious diseases profoundly shaped politics, commerce, and culture. In epidemics, none were spared. Smallpox likely disfigured and killed Ramses V in 1157 BCE, although his mummy has a significant head wound as well.2 At times political upheavals exasperated the spread of disease. The Spartan wars caused massive dislocation of Greeks into Athens triggering the Athens epidemic of 430–427 BCE that killed up to one half of the population of ancient Athens.3 Thucydides’ vivid descriptions of this epidemic make clear its political and cultural impact, as well as the clinical details of the epidemic.4 Several modern epidemiologists have hypothesized on the causative agent. Langmuir et al.,5 favor a combined influenza and toxin-producing staphylococcus epidemic, while Morrens and Chu suggest Rift Valley Fever.6 A third researcher, Holladay believes the agent no longer exists.7 From the earliest times, man has sought to understand the natural forces and risk factors affecting the patterns of illness and death in society. These theories have evolved as our understanding of the natural world has advanced, sometimes slowly, sometimes, when there are profound break- throughs, with incredible speed. Remarkably, advances in knowledge and changes in theory have not always proceeded in synchrony. Although wrong theories or knowledge have hindered advances in understanding, there are also examples of great creativity when scientists have successfully pursued their theories beyond the knowledge of the time.

Since such disease can affect any and all organs and systems, this specialist must be prepared to deal with any region of the body. The specialty of Medical Microbiology and Infectious Disease consists primarily of four major spheres of activity: 1. the provision of clinical consultations on the investigation, diagnosis and treatment of patients suffering from infectious diseases; 2. the establishment and direction of infection control programs across the continuum of care; 3. public health and communicable disease prevention and epidemiology; 4. the scientific and administrative direction of a diagnostic microbiology laboratory. Source: Pathway evaluation program 3 General information Once you’ve completed medical school, it takes an additional 5 years of Royal College-approved residency training to become certified in medical microbiology and infectious disease.

Resuming Sexual Activity How to Avoid Giving Or Getting an STD
Resuming sexual activity STOP having sex with others until you take the medicine, and DO NOT have sex for the next 7 days after taking the medicine. It takes 7 days for the medicine to work in your body and cure chlamydia infection. If you have sex without a condom during the 7 days after taking the medicine, you could still pass the infection to your sex partners, even if you have no symptoms. While using condoms correctly and every time you have sex is effective, the safest way to make sure you do not pass this infection on to anyone else is to NOT have sex for 7 days. How to avoid giving or getting an STD: •Practice abstinence •Use condoms every time •You and your partner commit to only having sex with each other •Get vaccinated for HPV •Get tested for all STDs Chlamydia Treatment Information URGENT HEALTH MATTER PRIVATE & CONFIDENTIAL Important information about your Yhoue haavel btehen exposed to someone who was diagnosed with chlamydia, a curable sexually transmitted disease (STD) . Chlamydia can be transmitted through oral, vaginal, or anal sex with a person who has a chlamydia infection. Chlamydia infection is easily treated with the medicine azithromycin (also known as Zithromax). People with chlamydia infection may not know they have it because most people have no signs or symptoms. Your sex partner has given you azithromycin (pills) medicine or a prescription for azithromycin medicine. This medicine or prescription was given to your sex partner by a doctor or other medical provider to treat YOU. It is very important for you to see your own doctor or medical provider as soon as possible to be examined and tested for this infection.
