The science and study of bacteria, and hence a specialized branch of microbiology. It deals with the nature and properties of the bacteria as living entities, their morphology and developmental history, ecology, physiology and biochemistry, genetics, and classification.

The major subjects that have consecutively occupied the forefront of bacteriological research have been the origin of bacteria, the constancy or variability of their properties, their role as causative agents of disease and of spoilage of foods, their significance in the cycle of matter, their classification, and their physiological, biochemical, and genetic features.

the study of bacteria; a division of the broader scientific discipline microbiology. Bacteriology is divided into a number of independent branches. General bacteriology studies the morphology, physiology, and biochemistry of bacteria, their mutability and genetics, evolution, distribution in nature, and so on. Medical and veterinary bacteriology studies the biology of pathogenic bacteria, methods of isolating and identifying them, and the phenomenon of immunity; it elaborates specific means for preventing and treating infectious diseases of man and animals. Agricultural bacteriology studies the role of bacteria in the formation of soil structures, in soil fertility, and in plant nutrition, and the processing of agricultural products (ensilage, fermentation, retting, and so on). Technical (industrial) bacteriology studies the processes of formation by bacteria of alcohols, organic acids, enzymes, amino acids, antibiotics, growth stimulants, and other substances.

Bacteriologic cure was achieved in 21 of the 23 patients (91%) in the amoxicillin group and in 23 of the 27 patients (85%) in the roxithromycin group (NS, Fisher's exact test).
At the completion of therapy, a clinical response was seen in 79, 72, and 41% of the ears, respectively; corresponding bacteriologic cure rates were 67, 67, and 20%.
* RESULTS At 4 to 11 days post-therapy, the efficacy analysis showed that patients treated with ciprofloxacin had a better bacteriologic cure rate than the patients treated with TMP-SMZ (99% vs 89%, P=.004; number needed to treat [NNT]=10) and a better clinical cure rate (96% vs 83%, P=.002; NNT=7.6).
The odds ratio for clinical success using a fluoroquinolone is 1.7, compared with the use of a non-fluoroquinolone treatment; the odds ratio for bacteriologic success is 1.8.
We retrieved data from 2 databases: one at the National Institute for Public Health and the Environment (RIVM), Bilthoven, the Netherlands, which contains the bacteriologic information of all M.
With the sort of antibiotic concentrations and the sort of pathogens we are treating, it would be very unusual to see a bacteriologic failure with a quinolone.
The bacteriologic cure rate was better in the amoxicillin group than in the penicillin group (76% vs.
The test is significantly more effective than both bacteriologic methods and enzyme-linked immunosorbent assay for detecting positive clinical specimens, and its shelf life is 21 days when stored at below 60[degrees] C.
In reality, though, the correlation between bacteriologic resistance and clinical response is not very strong.
CDC, in collaboration with state and local health departments, uses three sources to monitor progress toward these goals: 1) an individual-case surveillance system, 2) TB mortality data from CDC's National Center for Health Statistics (NCHS), and 3) program performance data collected on cases, contact follow-up, bacteriologic conversion of sputum, continuity of drug therapy, completion of therapy, and preventive therapy.
The infection was suspected after examination by electron microscopy and confirmed by bacteriologic and immunohistochemical investigations; finally, the bacterium was identified as B.
