Bacteriological condition

Water-industry sealants have a fast cure rate and the ability to accept early cyclic movement, even at low temperatures. They provide long-term performance under permanently immersed conditions and are resistant to anaerobic bacteriological conditions associated with sewage. 

The permeate side is liquid-filled and kept at a low internal volume, and there is flow in all parts of the permeate system, securing safe bacteriological conditions. 

In the food and dairy industries, the sanitation and cleaning of the plant are extremely important. Here, the easy access to each membrane is very valuable for the inspection as well as an immediate exchange of broken membranes, securing optimum bacteriological conditions.

A SELECTION OF RECENT SURVEYS ON THE BACTERIOLOGICAL CONDITION OF SOME FOODS WHICH PROVIDE VALID INFORMATION FOR THE CALCULATION OF REFERENCE VALUES... 

Duration - Duration of therapy varies with the type and severity of infection as well as the overall condition of the patient therefore, determine duration by the clinical and bacteriological response of the patient. In severe staphylococcal infections, continue nafcillin therapy for at least 14 days. Continue therapy for at least 48 hours after the patient has become afebrile and asymptomatic and cultures are negative. The treatment of endocarditis and osteomyelitis may require a longer duration of therapy. 

In such experiments, a preliminary preparation of the often difficulty obtainable pure thioaldehydes is not actually necessary. It suffices to bring the fermenting yeast in contact with the ordinary (non-thio) aldehydes and with ammonia and hydrogen sulfide (ammonium hydrogen sulfide). Such conditions frequently apply for animals and plants, for example, in bacteriological processes and probably also in the metabolism of higher organisms. 

Both B. coli and B. lactis aerogenes belong to a class of organisms that are able to develop free hydrogen under certain conditions. Their metabolism thus shows certain phases approaching those phenomena of other bacteriological fermentations in which the formation of hydrogen is a necessary step. 

COPD exacerbations. Therefore, in exacerbation treatment with antibiotics is justified when the patient has at least two of three features of increased dyspnea, increased sputum volume, and sputum pu-rulence. Antibiotic choice will depend on local experience derived from local bacteriological sensitivity data. Older, less costly compounds such as tetracycline, doxycycline, amoxicillin, erythromycin, cefaclor etc. are often as effective as newer, more expensive ones. If resistant organisms are suspected or when the severity of the patients clinical condition puts them at high-risk of treatment failure, a second or third generation cephalosporin, fluoroquinolone, newer macrolide or broad-spectrum penicillin may be preferred. In cases of recurrent infection prolonged courses of antibiotics continuous or intermittent, may be useful. 

A low-pressure mercury lamp sold by Westinghouse under the trade-mark, Sterilamp, was placed on the market in 1936. The lamp was primarily designed to emit a copious amount of bactericidal ultraviolet radiation with a minimum amount of radiation below 2000 A. The latter radiation is responsible for the photochemical production of ozone from oxygen of the air. The effectiveness of the lamp in destroying bacteria (2S) and mold 21) on Petri plates, in operating rooms 17,18), bacteriological laboratories 32), and air-conditioning systems 22, 24) has been amply demonstrated. 

The results of the great number of bacteriological tests carried out cannot be condensed into understandable tables because the tests differed too much one from another. In most cases they are not readily comparable because the conditions of operation were often intentionally modified. Accordingly, it is necessary to consider each bacteriological test separately on the basis of the conditions which prevailed during the operation. 

The Bacteriology Department at the ATCC determined the appropriate culture conditions for this microorganism, and tentatively identified it as a Coryne-bacterium. Antibiotic sensitivity tests revealed bacteriostasis with some compounds but no bactericidal antibiotics have yet been found. 

Period of vital functions of bacteria under slow contamination is taken 200 days, under mass infection (natural or man-caused disaster) or continuous contaminant spill conditions it is taken 400 days. Six categories of ground water vulnerability to bacteriological contamination have been distinguished (Table 3) ... 

Pure Cultures.—To determine the properties due to a particular yeast, it must be separated from all other organisms with which it is associated and when grown thus, free from all contamination, it is then known as a pure culture. A commercially pure yeast is different, as this simply means free from added non-yeast matter. This is the condition of most compressed yeasts as found on the market they are commercially, but not bacteriologically, pure, since they have numbers of bacteria and molds associated usually with more than one yeast variety. 

As a rule, the initial stage of petroleum extraction from oil wells occurs under the natural layer pressure practically without contamination with water. With time, however, the water layer gets produced together with the petroleum layer. About two-thirds of all petroleum is extracted in high humidity conditions. Water layers can differ considerably by their chemical and bacteriological contents. During the extraction of this mixture of petroleum with water layer, an emulsion is formed. Emulsions can be considered to be a physical mixture of two immiscible liquids, one of which is distributed in another phase as droplets of various sizes. The water present in petroleum results in an increase in the transportation price because of an increase in both volume and viscosity of the resulting liquid to be transported.
