Finding that he could restore the bacteriolytic power of See also Fossilization of bacteria; Photosynthetic microorgan- the antiserum if he added a little fresh serum from a non- isms immunized animal, Bordet concluded that the bacteria-killing phenomenon was due to the combined action of two distinct substances: an antibody in the antiserum, which specifically BORDATELLA PERTUSSIS • see PERTUSSIS acted against a particular kind of bacterium; and a non-spe- cific substance, sensitive to heat, found in all animal serums, which Bordet called “alexine” (later named “complement”). In a series of experiments conducted later, Bordet also BBordet, JulesORDET, JULES (1870-1961) learned that injecting red blood cells from one animal species Belgian physician (rabbit cells in the initial experiments) into another species (guinea pigs) caused the serum of the second species to Jules Bordet’s pioneering research made clear the exact man- quickly destroy the red cells of the first. And although the ner by which serums and antiserums act to destroy bacteria serum lost its power to kill the red cells when heated to 55 and foreign blood cells in the body, thus explaining how degrees centigrade, its potency was restored when alexine (or human and animal bodies defend themselves against the inva- complement) was added. Bordet was also responsible for hemolytic (red cell destroying) serums acted exactly as bacte- developing complement fixation tests, which made possible riolytic serums; thus, he had uncovered the basic mechanism the early detection of many disease-causing bacteria in human by which animal bodies defend or immunize themselves and animal blood.

However, when serum containing the antibody spe- received an appointment to the École Moyenne, a primary cific to the bacteria was destroyed, the alexine and the solution school. Jules and his older brother Charles attended this school separated into a layer of clear serum overlaying the intact red and then received their secondary education at the Athéné cells. Hence, it was possible to visually determine the pres- Royal of Brussels. It was at this time that Bordet became ence of bacteria in a patient’s blood serum.

For Already famous by the age of thirty-one, Bordet this work, the Belgian government awarded him a scholarship accepted the directorship of the newly created Anti-rabies and to the Pasteur Institute, and from 1894 to 1901, Bordet stayed Bacteriological Institute in Brussels in 1901; two years later, in Paris at the laboratory of the Ukrainian-born scientist Élie the organization was renamed the Pasteur Institute of Brussels. In 1899, Bordet married Marthe Levoz; they From 1901, Bordet was obliged to divide his time between his eventually had two daughters, and a son who also became a research and the administration of the Institute. Soon after his arrival at the Institute, he began work other activities, he continued his research in immunology and on a problem in immunology. In 1906, Bordet and Octave Gengou succeeded 83 Borel, Jean-François WORLD OF MICROBIOLOGY AND IMMUNOLOGY in isolating the bacillus that causes pertussis (whooping isolated compound selectively suppressed the T cells of the cough) in children and later developed a vaccine against the immune system. By the end of that decade, Borel had demonstrated the studies on the coagulation of blood. The Traité de l’immunité dans les maladies infectieuses (1920), a compound was found to be insoluble.

Within three months of start- ing school 100mcg proventil for sale asthma symptoms in adults cough, she suddenly developed problems buy 100 mcg proventil overnight delivery asthma treatment ventilator. Even though by being in school with other children she had more stimulation than ever before, she seemed less inquisitive or interested in things than she had been. Slowly she stopped learning new words, her vocabulary became limited, and she seemed listless. Lourdes stopped listening to her parents and teacher and even refused to look at the person speaking to her. When Lourdes wasn’t being difﬁcult, she seemed to withdraw into herself. Lour- des’s mother immediately took her to the pediatrician who, after listening to her symptoms, reassured Elise that some children were just “wired that way. Not only did Lourdes not grow out of it, she became progressively worse over the next three months. First, not feeling conﬁdent that her pedi- atrician was right in disregarding the teacher’s suggestion that Lourdes might be autistic, Elise logged onto the Internet. It became clear that her daughter did not have any of the signiﬁcant symptoms or signs that one would expect with autism. Fortunately, Elise had heard about the Eight Steps to Self-Diagnosis from a friend, and before she began putting her child through all kinds of medical testing, she decided to work through them. In returning several times to Step Two, relating to the history of Lourdes’s symptoms, she real- ized that her daughter had started exhibiting all her symptoms soon after she had caught a bad cold from the children at school. Then in considering Step Three relative to what made her daughter’s symptoms worse, she noted that Lourdes was especially resistant and inat- tentive when they were driving in the car, with the little girl in the back in a child’s car seat. Lourdes seemed best when her mother had her attention and was having a direct conversation with her. In other words, Elise had to have a face-to-face interaction to get her daughter’s attention. Instead of returning to the pediatrician, Elise took her daughter to an audiologist, who discovered that Lourdes had a signiﬁcant hearing loss. This 198 Diagnosing Your Mystery Malady explained a lot, such as why she wasn’t “listening” to the teacher or her par- ents and seemed inattentive, as well as why her vocabulary wasn’t expand- ing in either Spanish or English. Lourdes was worse in the backseat of the car because she couldn’t read her mother’s lips, whereas when she was engaged in direct eye contact and conversation, she became communicative again. Since these symptoms started when Lourdes became sick, Elise took her daughter to an ear, nose, and throat doctor. He found that both of her middle ears were full of ﬂuid—the remnants of the cold that Lourdes caught after beginning nursery school. Once they placed drain tubes in Lourdes’s eardrums (tympanic mem- branes), her hearing improved dramatically. Her vocabulary caught up to her age level, and Lourdes returned to being the bright, inquisitive, and well- behaved child she once was. Without solid research on the Internet and a step-by-step analysis, Lourdes’s mother would not have been able to get the help her daughter needed as quickly as she did. Case Study: Justin Justin was a nine-year-old who had just earned his ﬁrst badge as a Cub Scout. After he attended scout camp that summer and achieved his second badge, he informed his parents he intended to work toward becoming an Eagle Scout. His parents were pleased and hoped his ﬁve-year-old brother would follow in his footsteps. One morning, Justin’s brother told his parents that Justin was not sleeping and was walking around the house during the night. Justin’s folks began to worry that there was something going on at school that their son was not talking about. When they confronted him, he denied anything unusual was happening there. One day Justin began to complain that he had tingling in his hands and feet. Sometimes he wet his pants, and other times he went for long periods without urinating at all.

Gaps or sketchy notes indicate that further reading or more in-depth study is required buy proventil 100mcg lowest price asthma awareness month. A reference source Notes contain information that will be of use to you in preparing essays cheap 100mcg proventil otc asthma definition 64g. This may be data that can be included in your assignment, or it may be ref erences to other sources. Reading through your notes may even inspire you about topics that you would like to study in more depth. An aide-mémoire Notes will help to remind you of facts, figures, theories and practical appli cations that would otherwise be forgotten. Their permanent and personal nature means that you will be able to return to them at any point – so you can find information you have collected from journal articles, books and audiovisual material without the need to seek out the original texts or tapes. A learning tool Notes are a way of organising information, which will help you make sense of what the lecturer or author is trying to convey. In good notes, the key in formation will be highlighted and clearly distinguished from supporting examples and explanations. The link between topics will be clear, and you will be able to see how smaller details fit into the whole picture. A revision aid Your notes as a whole will provide you with an overview of the areas around which to plan your revision. They can also be used to help you re member key facts and identify themes. The actual task of note-taking itself is one way of starting to memorise the material. Rereading notes at regular intervals helps to consolidate the retention of this information. They are not usually placed under ex ternal scrutiny, nor do they form part of any assessment. There is no direct system for evaluating the ability of a student to make relevant and useful notes. How ever, this does not help students identify ways to improve their skills or how to make the most of the information they have recorded. Some students are uncertain about which pieces of information they should be noting. In order not to miss anything they conscientiously re cord every utterance of the lecturer, or neatly précis a chapter or article. This results in over-detailed notes where it is difficult to identify the key points or get a perspective of the topic as a whole. It is also extremely te dious for the student and does not promote active listening or critical thought. This may miss out some of the key points and make it difficult to use the notes for revision. The amount and type of information that needs to be recorded will vary between students. It depends very much on what individuals need in order to make sense of what is being presented to them. Different styles of note-taking Have you ever considered the way in which you record information? Most of us tend to follow the style of note-taking shown to us at school. The fol lowing section describes several different methods of note-taking. They are the most traditional approach to note-taking, and the one most likely to have been modelled at school. Information is recorded in the same sequence in which it is given, thereby replicating the lecturer’s or the author’s organisation of the information. Headings, underlining, numbering or lettering systems are used to indicate the hierarchy and distinguish one topic from another. Disadvantages ° Sequential note-taking is often a passive task that allows students to avoid interpreting and assimilating information for themselves.
