bac·te·ri·a(bak-tēr'ē-ă), Do not use this word as a singular noun. (In Spanish, however, bacteria is singular, bacterias plural.)
Bacteria/Bac·te·ria/ (bak-tēr´e-ah) in former systems of classification, a division of the kingdom Procaryotae, including all prokaryotic organisms except the blue-green algae (Cyanobacteria).
bacteria/bac·te·ria/ (bak-tēr´e-ah) plural of bacterium.
splenomegalyEnlarged spleen Enlargement of spleen for any reason, which is usually a manifestation of underlying disease; the only specific finding in splenomegaly is dragging sensation in the upper right quadrant; megalic spleens may reach 4.0+ kg–eg, in agnogenic myeloid metaplasia
transfusion reactionBlood transfusion reaction, incompatibility reaction Transfusion medicine Any untoward response to the transfusion of non-self blood products, in particular RBCs, which evokes febrile reactions that are either minor–occurring in 1:40 transfusions and attributed to nonspecific leukocyte-derived pyrogens, or major–occurring in 1:3000 transfusions and caused by a true immune reaction, which is graded according to the presence of urticaria, itching, chills, fever and, if the reaction is intense, collapse, cyanosis, chest and/or back pain and diffuse hemorrhage Note: If any of above signs appear in a transfusion reaction, or if the temperature rises 1ºC, the transfusion must be stopped; most Pts survive if < 200 ml has been transfused in cases of red cell incompatibility-induced transfusion reaction; over 50% die when 500 ml or more has been transfused; TF mortality is ± 1.13/105 transfusions Clinical Flank pain, fever, chills, bloody urine, rash, hypotension, vertigo, fainting
bacteriaSingle-celled, microscopic, living organisms occurring in countless numbers almost everywhere. Most are harmless; only a small proportion cause disease. Bacteria may be cocci which are spherical and usually about 1000th of a millimetre (1) in diameter. These include bunched staphylococci and single-strand grouped streptococci. Bacilli are straight rod-shaped organisms; vibrios are curved; and spirilla (including spirochaetes) are wavy. Bacteria reproduce rapidly with a generation time, under ideal conditions, of about 20 min. Those that cause human disease reproduce best at human body temperature (37° C). Some of them are unable to synthesize DNA at 42° but will do so readily at 37°. Bacteria produce powerful poisons (toxins) which are among the most poisonous substances known. It is the toxins that cause disease by binding on to body cells, gravely affecting their function or even survival.
Bacteria(Eubacteria) one of the primary groupings (DOMAINS) of organisms according to CLASSIFICATIONS based on genetic structures and sequences.
bacteriaglobally ubiquitous microscopic organisms, crucial to the ecosystem because of their metabolic turnover, for example, of nitrogen, carbon and sulphur. Bacteria were named from the Greek for rod, but only some (bacilli) are rod-shaped; others are spherical (cocci), curved or spiral (vibrios, spirilla, spirochaetes). Bacteria can be pathogenic to humans, other animals and plants, or non-pathogenic. Pathogens may be virulent and always cause infection whereas others, known as opportunists, usually only cause infection when the host defences are impaired. Non-pathogenic bacteria may become pathogenic if they move from their normal site, e.g. when normally beneficial ('probiotic') intestinal bacteria contaminate and infect a wound. Many bacteria have developed adaptations that allow them to exploit environments and survive unfriendly conditions - significantly, in modern times, enzymes that destroy antibiotics. Bacteria are classified and identified by features that include, as well as shape, staining characteristics (Gram positive or Gram negative) and whether or not they require oxygen (aerobic or anaerobic). sing bacterium.

Patient discussion about bacteria
Q. How the bacterias are produced?
Q. I am wondering why did he prescribe me a bacteria? My doctor has prescribed some probiotic medicines for diarrhea recently and these medicines are actually bacteria…..I am wondering why did he prescribe me a bacteria?
Q. Dog waste bacteria. How bad is it.Dose it ever die? WdWilliam@aol.com My husband has invented a Pet Waste-A-Way it liquefies the dog waste & it goes into the earth with in 8 seconds.We are worried about the environment & what it would do. We have gotten info back both ways. Some say it is there if you have dogs & some say it is bad & never dies.
