Applied Bacteriology for Nurses

Abstract

* Yeasts are microscopic, unicellular vegetable organisms that multiply by a peculiar process called budding. CHAPTER II CHARACTER OF BACTERIA Bacteria are extremely minute living organisms. Seen under a powerful microscope they appear as little rods, sphere's, or spirals. It is difficult for one unaccustomed to the use of a microscope to conceive of the size of these microorganisms. They vary in size from^q q to 1^i nch, so that a tiny drop of pus often contains many thousand bacteria. Even a minute dust mote floating in the air may carry them. Bacteria are one-celled organisms, i. e., each cell is a complete individual. There is no head, no tail, and not even the NDEX Abscess, 52 stitch, 112 Achorion schonleinii, 185 Acid, effect of, on stained bacteria, 26 formed by bacteria, 35 Acid-fast, definition of, 26, 77 Aedes calopus mosquitoes, 58, 132 Aerobic bacteria, definition of, 20 Agglutination jf typhoid bacilh, 71 Agglutinin, nature of, 70 Alcohol, effect of, on leukocytes, 67 Anaerobic bacteria, definition of, 20 Anaphylaxis, nature of, 75 Animal parasites, 152 Anopheles in malaria, 58, 128 mosquitoes, 131 Anthrax, bacillus of, 180 immunity of dogs to, 64 through food, 144 Antibodies as defence against bacteria, 67 Antimeningococcus serum, 115 Antiseptic surgery, Lister's, 12 Antiseptics, effect of, on bacteria, 36 Antistreptococcus serum, 110 Antitoxin of diphtheria, 99 of tetanus, 103 Antitoxins, nature and role of. 67 Arnold steam sterilizer, 45 sterilizer for milk, 136 Autoclave, 46, 157 Bronchopneumonia, 100 Budding, definition of, 13 Cy-LMETTE test for tuberculous infection, 94 Cancer, relation of bacteria to, 49 Carbolic acid, effect of, on bacteria, 38 Carriers in the transmission of disease, 50 Cellulitis, 52 Chancre in syphihs, 119 Chicken-pox, quarantine in, 03 Chickens, immunity to tetanus, 04 Chloramine-T as disinfectant, 41 Chlorid of lime, effect of, on bacteria, 39 Chlorin in disinfection of water, 39, 149 Cholera, bacteriology of, 88 carried by water, 147 quarantine in, 03 spirillum, 88 treatment of, 79 Coccus, definition of, 15 Cold, effect of, on bacteria, 30 on leukocytes, 07 Colon bacillus, 174 in food poisoning, 144 in sanitary water examinations, 151 Colostrum, role of, in transmission of immunity, 05 Complement, role of, 70 Cow-pox, 124 Creolin, effect of, on bacteria, 38 Culex in relation to malaria, 58 Cultures, method of making, 27 Cytolysin, nature of, 09 Daktx's solution, 41 Davaine, anthrax discoveries, 11 Delousing, 109 Dengue, virus of, 127
