Q: Bacterial beacons Where the green light fluoresces, genes extracted from cigarettes match those for a different known bacterium. A. SapkotaThe tobacco in cigarettes hosts a bacterial bonanza — literally hundreds of different germs, including those responsible for many human illnesses, a new study finds.“Nearly every paper that you pick up discussing the health effects of cigarettes starts out with something to the effect that smokers and people exposed to secondhand smoke experience high rates of respiratory infections,” notes Amy Sapkota of the University of Maryland, College Park. The presumption has been that smoking renders people vulnerable to disease by impairing lung function or immunity. And it may well do both.“But nobody talks about cigarettes as a source of those infections,” she says. Her new data now suggest that’s distinctly possible.If these germs are alive, something she has not yet confirmed, just handling cigarettes or putting an unlit one to the mouth could be enough to cause an infection.The idea that tobacco might contain viable germs isn’t just idle conjecture. Several research teams have isolated bacteria from tobacco that they could grow out in petri dishes. Those earlier investigations tended to hunt for — and, when found, attempted to grow — only one or two species of interest, Sapkota says.What’s novel in her study: She and her colleagues probed for genetic material from any and every bacterium in a cigarette’s tobacco. Under sterile conditions, the researchers opened up cigarettes and then performed a series of tests on the leafy bits. For instance, they isolated all of the ribosomal material and then homed in on its long, species-specific stretches known as 16S regions. These genetic segments were then compared to 16S patches characteristic of known bacterial species.Sapkota’s team had 16S probes for close to 800 different bacteria and found matches to many hundreds in the four brands of cigarettes screened: Marlboro Red, Camel, Kool Filter Kings and Lucky Strike Original Red. These cigarettes are “among the most commonly smoked brands in Westernized countries and represent three major tobacco companies,” Sapkota notes. All were purchased in Lyon, France, where she was completing her postdoctoral studies.Among the large number of germs whose DNA laced these cigarettes were: Campylobacter, which can cause food poisoning and Guillain-Barre Syndrome; Clostridium, which causes food poisoning and pneumonias; Corynebacterium, also associated with pneumonias and other diseases; E. coli; Klebsiella, Pseudomonas aeruginosa and Stenotrophomonas maltophilia, all of which are associated not only with pneumonia but also with urinary tract infections; and a number of Staphylococcus species that underlie the most common and serious hospital-associated infections.Sapkota’s team lists many of these — including the most prevalent bacteria in the tobacco they studied — in a paper published early, online in Environmental Health Perspectives.Some people have criticized the idea of infectious cigarettes, arguing that as tobacco burns, it would kill any germs present. But Sapkota is not so sure that’s true. The tobacco farthest from the burning tip might be a balmy temperature, from a bacterial point of view. And here’s “a really wild idea,” she says: What if the smoke particles traveling through the still-unburned part of a cigarette pick up some germs and then ferry them deeply into the lung, where they’re unlikely to be cleared? Wouldn’t that be the prescription for disease?Of course, there’s also plenty of chances for a smoker to become exposed prior to lighting up. And, of course, the potential for highest oral exposure would come from chewing tobacco — and nasal exposures from snuff.Sapkota, an environmental health scientist, plans to follow up her preliminary data to see which types of tobacco are most likely to host viable germs, and whether those bacteria are transported into the body, either during smoking or by the insertion of unburned tobacco products (including chewing tobacco) into the mouth.Several thousand potentially toxic chemicals have been isolated from cigarettes. Sapkota says that it’s not hard to imagine that the number of germs hosted by tobacco products could rival that of the carcinogens and other poisons residing in or produced by burning tobacco.How so, when she’s only found genetic material indicting hundreds of germs? Owing to the bacterial probes available when Sapkota began her tobacco work, she was only able to screen for 700-odd species. But newer probes on the market can now screen for the bacterial 16S genetic material of 5,000 or more germs. And if she used such huge batteries of probes now, she said she fully expects she could turn up at least 1,000 hitchhiking bacterial species in tobacco products.

A: Tobacco is a plant, of course it will have microbes. Are these any different from the microbes on lettuce or cabbage? Before publishing, she should have at least done that comparison.The article states that they don’t know whether or not the microbes are alive. Tobacco is heavily processed before being made into cigarettes, while foods are not, and I don’t remember ever hearing of someone getting salmonella from smoking. I’m not a smoker, and think smoking is incredibly stupid, but this is really taking anti-tobacco research to an absurd level.

Please help me find a title!?!?

Q: ____________ :The hazards of smokingThis is the essay. Warning everything on here is not real. It’s a “Fake Essay”“Smoking is a very hazardous habit. It is actually the most dangerous legal consumer product on the face of this planet.” Dr. Melbourne Fox, Director of American Lung Association (Melbourne 25).In this generation, smokers are everywhere: on TV, movies, and even just walking down the street. Famous, young people smoke and it encourages other younger people to do. Smoking ages range from pre-teens to the elderly. What many people don’t know that that even though it may be cool and hip, it can cause serious problems for them. Smoking is well known to cause many unhealthy habits in people’s lives and even affect peoples’ mental and physical health. Smoking can cause serious health issues. It hurts people besides the smoker. Also, it can cause addiction. Although many smokers claim that smoking helps them, there are many more cons that out-weigh the pros.Smoking can cause lots of different health problems. In the book, Health Effects of Smoking, by Dr. Carey Melbourne, writes, “Smoking harms nearly every organ of the body, causing many diseases” (Melbourne 5). Smoking hurts the body, so in general, it deteriorates the smoker’s health. As a result, the smoker ends up with diseases. Dr. William deGraffenried, a researcher, writes about this in his article, “Why Smoke?” He writes, “Smoking causes cancers of the bladders, pharynx, larynx, and lungs. It also causes serious heart and respiratory diseases” (deGraffenried 9). Studies show that people that had smoked or are smoking, had at least one chronic disease. These diseases can be very harmful to the human body and can even result in death. Now that we know what smoking can do to a smoker’s body, let’s see what it can do to others. Secondhand smoke can be harmful in its own way. It is very dangerous to expose anybody to secondhand smoke. Melbourne writes, “The more secondhand smoke humans are exposed to, the higher the level of these harmful chemicals in your body” (Melbourne 12). Even if a non-smoker does not smoke, just being around smoke can be hazardous to ones’ health. Parents have to be on watch when they smoke. Any type of exposure to their children can be harmful. DeGraffenried writes, “Secondhand smoke is responsible for 20,000 to 1 million children for having asthma attacks and 150,000 to 300,000 infants that are younger than 18 months of age to have lung infection (such as pneumonia and bronchitis)” (deGraffenried 15). Pregnant woman should also be aware of what is around them. Any type of smoke can cause their babies to have low birth weight or can even cause SIDS (Sudden Infant Death Syndrome). Secondhand smoke is really serious and the effects are preposterous. Nonsmokers should be aware and try to avoid it. We should now take a look at another bad habit of smoking, addiction.Addiction is the state of being enslaved to a habit or practice or to something that is psychologically or physically habit-forming. This state is as much a threat as anything. Nicotine is found in substantial amounts in all forms of tobacco. Nicotine is a substance that can become addicting for the human body. Once inhaled it reaches the brain within seconds. Melbourne writes about the effect: “ As the nicotine level drops in the blood, smokers feel edgy and agitated–the start of nicotine withdrawal. So in order to relieve the discomforts, the smoker light up another cigarette…then another…and another” (Melbourne 3). As a result the smokers wants more to satisfy their need and end up becoming addicted to it. Melbourne writes, “Although 70% of smokers want to quit and more than 40% try to quit each year, fewer than 5% succeed” (Melbourne 6). This happens because smokers are not only physically addicted to it, they are emotionally linked to it. This trait makes it harder for smokers to break the habit.Even with all the awful things that smoking can do to our bodies, there are still people that think the opposite. Smokers claim that smoking is not bad for them at all, on the contrary it is good for them. Smoker, Gabriella Dominguez, states,” By smoking I feel relief from all the stress that I have. It helps me relax and lets me focus more.” Dr. Lana Cain, on her website Benefitsofsmoking.com writes, “Smoking burns up an extra 300 calories each day. This method is really good and to stop using it would cause a huge gain of obese people in America”. But is it really worth the risk of getting a fatal disease? While this may be true for the smoker, nonsmokers have different views. The risk of getting sick or hurting others may be more important than relaxing or losing weight..With so many sickness caused by smoking, the risk of hurting others, and the risk of addiction, it is easy to see why many people do not smoke. Also the ability to cause cancer, low birth weight, and the way smokers depend on it is not a very attractable impression either.

A: “Playing With Fire”~M~

What does this sentence mean EXACTLY?

Q: “From animal studies, we know that multiple components within cigarettes are harmful to the developing fetus and can cause mutations that might lead to birth defects,” Malik said.I just want to know is the sciencest referring to animals as in us humans or other animals such as mice.Here is a link to the article:http://prenatal-health.suite101.com/article.cfm/smoking_and_heart_birth_defectsThanks for your help.

A: Both the genetics of human and animals are very simular. So things that affect the mouse will most likely affect humans. So he was referring that since the cigarettes have mutated the mice. Then they could have the same effect to the humans. So he was reffering to both.
