Question | Answer |
what is smaller than a virus | A prion |
what is the function of bacterial endospores | help keep bacteria alive in harsh conditions |
organisms that cause malaria and crypto | Protozoa |
Microorganism that live off dead or decaying material | Saphrocytes |
binary fission refers to | process of bacterial cell replication |
concept that disease is caused by microorganism | germ theory |
What is resent in viruses | DNA/RNA, unable to replicate w/o a host cell. Do not divide by binary fission, can't make their own energy and depend on host for protein and nucleic acid production |
Spontaneous generation | living things arise from nonliving things |
Found in Eukaryotic and not in Prokaryotic | Eukaryotic have a true nucleus and membrane-bound organelles, also larger than prokaryotes |
Bacteria that is round and in chains | Strepto (chain) cocci (round) |
What is cutaneous mycosis | Ringworm (tinea) |
Scientific name | Bacillius sabtilis (italicized) |
cause of spongiform encephalopathies | prion |
Escherichia coli infect what? | T-even phages |
Causes latent viral infection | herpesvirus |
infectious mononucleiosis | Epstein Barr |
Targets CD-4 cells | HIV |
Who advocated using disinfectants on hands and in air prior to surgery? | Joseph Lister |
Acid fast stain is used to determine | TB |
What stucture is mismatched for bacteria | Plasmid-provide cell locomotion (flagella cause locomotion) |
Function of fimbrae | adhering to other sttuctures |
Obligate parasite | ringworm |
pasteur used swam neck to prove | dust was a source of living organisms |
key feature of animal viral infections | separation of viral nucleic acid from capsid |
observed handwashing would reduce spread of childbed fever | Semmelweis |
After gram staining appears blue, elongated rods that is clustered | gram positive bacilli |
reproductive structure of yeast | Budding |
lives on or in person | indigenous microflora |
Fleming is known for | Penicillin |
microorganism is defined as | too small to be seen with the naked eye |
outcome of gram staingin | positive or negative depending on cell wall thickness |
what is not considered in classifying virus | number of genes |
what is not true of virus | replicate from binary fission |
having a nucleus | Eukaryotes |
Dutch merchant that made magnifying glass | Leewhenhook |
ability to exist as trop or cyst | Protozoa |
not characteristic of fungi | photosynthesis |
what is mycosis | fungal infection |
flagella all over cells | Peritrich |
Koch's postulates are used to establish | specific microbes cause specific diseases |
what causes intoxication | algae |
all bacterial cells have | one or more chromosomes |
viral multiplication | absorption, penetration, replication, assembly, release |
bacterial cells do not have | Cilia |
Oncovirus | cause CA, HPV |
infectious protein particles | Prions |
Molds reproduce | Spores |
Core of every virus always contains | either DNA or RNA |
peptidoglycan is found | cell walls |
false about viruses | contain DNA and RNA (only one) |
virulence factor | weapon or tactic that causes infection |
C. perfringins | food poisoning |
streptococccus pyrogenes | skin infection/strep throat |
incidence | Number of new cases of a disease in a population during a specific time |
endemic disease | always in the population(gonorrhea) |
Sporadic disease | a disease that occurs only occasionally in a population (tetnus) |
reserviors | where pathogens are harbored (animals, humans, contaminated food/water) |
vector | Arthropods that act as reservoirs (lyme) |
Formites | non-living objects that transmit pathogens (towels, bedding, telephone) |
highest mode of transmission | respiratory |
lest likely mode of transmission | intact skin |
antibiotics | substance produced from a living organism that can kill another organism |
antimicrobial agents | should kill/inhibit growth, not cause damage to host, stay in infected tissue long enough, kill pathogen |
actions of antimicrobial agents | inhibit cell wall synthesis, inhibit protein synthesis, damage cell membrane. DO NOT destroy capsule |
bacteriostatic durgs | stop the bacteria from reproducing but do not kill it. don't give to immunocompromised pt |
sulfa drugs | inhibit production of folic acid |
drugs that inhibit cell wall synthesis | penicillin and cephalosporin |
super bugs | microbes that are resistant to antimicrobial agents |
B-lactamase | produced by bacteria to inhibit the b-lactam ring, causing the drug to be ineffective |
conjunction | when a microorganism "shares" drug resistant information with another microorganism through a plasmid |
empiric therapry | drug therapy that is started before lab results are back |
artificial active immunity | immunity received through vaccination (flu shot) |
herd immunity | if everyone who is able to be immunized from a pathogen it protects those who cannot be immunized due to age or immunocompromised |
HAI | mainly UTI, also called nosocomial |
Surgical Asepsis | "sterile technique", all organisms including endospores are killed. for OR, L&D |
medical Asepsis | "clean technique" kills pathogens. |
Normal flora | on skin, mouth, nasal passages and distal urethra. Blood, lungs, CSF sterile |
Carriers | people who harbor a pathogen without showing symptoms of the disease |
Synergistic infection, polyorganism | when two organisms team up to cause a disease (trench mouth) |
Lab specimens | proper label, transport, selection and collection. not collected by lab and viability of sample is responsibility of collector |
N gonorrheae | needs special transport media |
infection | microorganism that is living and multiplying in the body. caused by microbes or the products of microbes |
Prodromal period | after incubation, beginning to feel non-specific symptoms of a illness |
phases of infection | infection can happen during any stage of infection |
acidophiles | like a pH <7 (stomach acid) |
sterilization | complete destruction of all microbes including spores and viruses, steam autoclave is best way |
Antisepsis | chemical agent applied to exposed body surface to disinfect skin and other living tissue |
Natural habitat for microorganism | reservoir |
indigenous to humans | viruses, bacteria, protozoa, fungi |
broad-spectrum antibiotics | cover a wide range of bacteria (gram negative and positive) |
to clean juice, wine, milk | pasteurizes |
non-standard practice in hospital | putting pt in private negative-pressure room. only for TB |
sing and not a symptom | temperature |
less antiviral, antifungal medication | they are so similar to human cells |
