Hello ! :) The answer to the first question, "Plasmodium" is actually called "Plasmodium falciparum" it is a protozoan parasite, one of the species of Plasmodium that cause malaria in humans. It is transmitted by the female Anopheles mosquito. Malaria caused by this species (also called malignant or falciparum malaria) is the most dangerous form of malaria, with the highest rates of complications and mortality.

The answer to the second question :) the "Pesticides" anti-insect sprays are used at very low concentrations to control Mosquitoes, and no adverse health risks are expected with its use for mosquito control. Negative health impacts would only be associated with long-term, repeated exposures to a chemical, not a short-term spraying episode. People who may be particularly sensitive to chemicals could possibly experience short-term effects, such as eye, skin, nose or throat irritation or breathing problems. Some pesticide residues may be present on outdoor surfaces after spraying. Studies on other chemicals suggest the amount of pesticide transferred to skin decreases with more time after spraying (and very little transfers 24 hours after spraying). Pesticides break down from surfaces more rapidly when exposed to sunlight and water.

For the third question, Bacteria resistant to antibiotics has increased because antibiotics were used so much that bacteria mutated (evolved) due to selective pressure (the antibiotic). If a bacterium carries several resistance genes, it is called multiresistant or, informally, a superbug. Antibiotic resistance is a consequence of evolution via natural selection.  The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce.  They will then pass this trait to their offspring, which will be a fully resistant generation.

Ad lastly number four :)  : There is another bacteria fighting anti-biotics that are stronger than ordinary anti-biotics. Vancomycin-resistant enterococci (VRE) are often present in the normal intestinal flora and in the female genital tract, as well as in the environment. Some of the other antibiotics that fail include some types of penicillin, cephalosporins, clindamycin, aminoglycosides, macrolides and others.  Most VRE infections occur in hospitals and are often acquired from other people or from contaminated food or water. Up to 66% carry enterococci in the mouth, especially patients undergoing endodontic treatment. VRE may be associated with endodontic failures. It can cause diareah, wound infection, bacteraemia or urinary tract infections, mainly in immunocompromised and medically ill patients. It may also give rise to endocarditis. Most VRE infections can be treated with antibiotics other than vancomycin.

Scientists still use anti-biotics and some have proven o be successful in treating bacteria illnesses, and are still used today.

srry i took so long! :P
