Antibiotics is a great success in the fight against bacterial infections. To understand how this fight is won, the first task is to explain exactly what an antibiotic is and does. The word first appeared in the 1940s and it refers to a substance produced by one bacterium or fungus that prevents the growth of another bacterium. It reflects the old saying, "Fight fire with fire". This refers to the use of fire breaks where you produce a controlled burn of one small area in the path of a larger advancing fire. So when the larger fire arrives, it runs out of fuel and dies. Applying this to medicine, research chemists developed a method of culturing bacteria or fungi that would produce a substance capable of killing or preventing other bacteria from reproducing. Penicillin, for example, is produced from a fungus while streptomycin is derived from the bacterium called Streptomyces. Thus, contrary to popular belief, antibiotics are “natural” in the sense that they are derived from bacteria or fungi occurring in the natural world. They are distinguished from drugs that are entirely artificial. For example, the sulphonamides have an antibacterial effect but are completely synthetic.
The continuing research and development work on antibiotics has paralleled the work in Eastern Europe and Russia to develop phages which are viruses that infect bacteria. This represents a different delivery system for killing or preventing the reproduction of bacteria. As more bacteria become resistant to antibiotics, more in the West are considering a switch to phages. It is hoped that new phages can be developed as a biocide for environmental surfaces in hospitals and other residential institutions to prevent the spread of methicillin-resistant Staphylococcus aureus (MRSA), C. Difficile and other life-threatening infections.
While work continues into the use of phages, doctors continue to rely on antibiotics which are divided into two classes depending on whether they are narrow or broad. A narrow antibiotic only targets very specific bacteria. A broad antibiotic is effective against a range of bacteria. Doxycycline is in the broad range.
Coming to the second question of how antibiotics work, some are bactericidal, i.e. they kill bacteria, whereas others are bacteriostatic, i.e. they prevent the bacteria from dividing and, as a result they die of old age. The problem is that, the more a bacterium is exposed to an antibiotic, the more likely it is to develop a resistance. This explains why, when you are prescribed an antibiotic, your doctor will always instruct you to continue taking the tablets until the end of the recommended course of treatment. You have to take the tablets even though you feel well. The reason? You are taking it to continue killing as many of the bacteria in your body as possible. The greater the number that survive, the more survivors there will be with resistance.
But there is a further problem. For decades, the farming industry has administered large quantities of antibiotics to the animals you eat. So instead of only consuming antibiotics when you are sick, there is continuous ingestion if you eat meat. As a result, many of the different strains of bacteria in the animal world have built up resistance. To prevent them from joining you, it is necessary to cook meat thoroughly. Heat kills most of bacteria that are dangerous to humans. If you eat meat rare, there is a risk of antibiotic-resistant bacteria taking up residence in your gut. Unfortunately, heat does not “kill” antibiotics so the bacteria in your body are continuously exposed to a low level dose of broad spectrum antibiotics all the time. This explains why there are now an increasing number of bacteria which are resistant to antibiotics.

Travelling on business is fun for the first few times. Especially if you have a career and a job that requires you to travel abroad, you are likely to think that travelling is glamorous. Many people believe so.
Not everybody will take to travelling overseas and living out of suitcase. It calls for a different mind set and attitude. Going to a foreign country where you do not know anybody personally, living in a hotel and eating unfamiliar food can take its toll on some people. Normally those who are home bound and attached to family find it difficult to tour abroad especially during weekends.
If you have to be travelling, it is better that you develop that attitude which will make you enjoy your travel. The positive side of the trips is that you get to see different countries, explore various tourist spots, understand different cultures, cuisine and importantly make new friends.
For people who are going to be posted overseas for short as well as long durations the companies offer training courses to help you understand the culture of the country where you are going to be based. They familiarize you with all the areas of communication, language, customs and living habits so that you know what to expect and are able to make headway in adjusting to the new culture.
Though most countries do have international shopping chains and malls like which is what probably you will look for in the first place, you will need to get a hang of the local milieu if you are going to stay put for a few weeks. Whatever familiarization sessions you might have, living in a foreign country especially in the beginning few weeks can be quite difficult till you get adjusted.
When you land in a new city and have to find your footing, you will need to be extra cautious and think on your feet all the time. You would need to observe everything and check with your local host before you venture into anything new.
While planning and packing for your overseas trip it is better to pack some of the essentials that you will need. It helps to carry some of the packaged food and tins that will help you feel at home until you get used to the local food or find the market where you can shop for the items that you want.
It helps to check out the weather conditions at the place where you are going and pack clothes accordingly. More importantly you should carry a medicine kit and stock it with all kinds of general and specific medicines in consultation with your doctor. This becomes critical since you may not be able to find a doctor immediately at the destination. New environment and weather can take a toll on you and it is quite likely that people will get some kind of cold and cough or other infections until they settle down and adjust to the new weather and climate. Therefore carrying general antibiotics like Zithromax and Pain killers besides Vitamin pills helps. On landing you might want to locate the nearest doctor as well as look for online website where you can order these medicines without having to go looking for a chemist.
If you plan and prepare well in advance, you will be able to enjoy your stay abroad without much problems and enjoy your stay as well.
Doctors need to keep an eye on those cases which are concerned with plague, according to a report published from Centers for Disease Control and Prevention.
In summer 2014, almost four people died of pneumonic plague in the U.S. Pneumonic plague is a rare disease caused by the same bacteria as bubonic plague. In this health problem, bacteria destroy the respiratory system so it should be dealt earlier when diagnosed.
The University of Texas Medical Branch at Galveston and Tekmira Pharmaceutical Corp researchers got success in developing a post-exposure treatment against specific Ebola virus that is the reason behind the death of thousands of people in West Africa.
