Project screening of cattle for 4

Background

 

Unrecognized colonization of patients and environmental contamination may contribute to cross-transmission

PDA LTACHs. We evaluated the sites

PDAs colonization of patients and the environment LTACH. Methods:

assessment of 17 patients found in the larger draft CCP screened at 4

LTACHs. The swab samples from each of the seven anatomical (rectal, inguinal, axillary

, elbow, lower back, urine, oropharyngeal / tracheal secretion), and

20 environmental strattera online facilities (eg, bed rails, overbed table, fan) were collected

. Slides were inoculated into tryptic soy broth + 1 mg / ml meropenem or covered directly MacConkey agar + 2

ertapenem disks. blah was confirmed by PCR. Isolates

identified to the species (MicroScan). Results: Mean age

65, 16 (94%) were receiving mechanical ventilation, 14 (82%) had fecal incontinence

and they were all chained to the bed. On the first day of observation, 14 (82%) patients received

CCP was detected in all patients. 16/17 (94%) patients in the

least one area of ​​skin is positive for CCP. 11/17 (65%) patients had 3 or more anatomic

Autotrophic bacteria (also known as autotrophs) ...

There are different groups of bacteria that belong to one family, and has evolved from the same bacterium (

ancestor). Nevertheless, each species of bacteria have their own features (those that developed after the separation from the original rock). Classification of bacteria: Bacteria are mainly classified by type (type is the scientific classification of organisms). For simplicity, the bacteria can be divided into the following groups:

Bacteria classification based on the forms as mentioned, before the DNA sequencing, bacteria were classified according to their shape and biochemical properties. Most bacteria belong to three basic shapes: rod (rod shape bacterium called bacillus), sphere (a sphere shape bacteria are called cocci) and spiral (spiral-shaped bacteria are called spirilla). Some bacteria are in different forms, which are more complex than the above forms. Aerobic and anaerobic bacteria: Bacteria are also classified based on the requirement of oxygen for their survival. Bacteria those need oxygen to survive are called aerobic bacteria and the bacteria they do not require oxygen to survive. Anaerobic bacteria can not carry oxygen and can die if we have in the environment of oxygen (anaerobic bacteria are found in places such as beneath the surface of the earth, the depths of the ocean, and bacteria that live in certain environments). Gram-positive and gram-negative bacteria: Bacteria are grouped as "Gram positive" bacteria and "gram-negative" bacteria, which are based on the results of Gram staining method (in which the agent is used to bind to the bacterial cell wall) to the bacteria. Autotrophic and heterotrophic bacteria: This is one of the most important types of classification strattera side effects, as it considers the most important aspect of bacteria growth and reproduction. Autotrophic bacteria (also known as autotrophs) to obtain carbon from carbon dioxide requires. Some autotrophs directly use sunlight to produce sugar from carbon dioxide, while others depend on various chemical reactions. Heterotrophic bacteria obtain carob and / or sugar from among them (for example, the living cell or organism they are). .

In the United States in 2003, Gram-negative bacteria have been associated with many of the most common types of nosocomial infections, including 71% of urinary tract infections, 65% of episodes of pneumonia, surgical infections 34% and 24% of bloodstream infections. Infections caused by gram-negative bacteria even higher percentage of nosocomial infections in Europe. A study published in the Journal of the American Medical Association (JAMA) in December 2009 found a "disturbing shift to infections caused by gram-negative pathogens" in the international study of the prevalence and outcome of infection in intensive care units. In this international study, gram-negative bacteria were present in 62% of positive strains of bacteria that exceed the Gram -positive bacteria by 47%. the type and prevalence of nosocomial infections caused by gram-negative bacteria in the United States changed in the late 1980s, with a decrease in contributions

sensitive to the magnetic field behavior of the bacteria was discovered more than 30 years ago

microbiologist Richard P. Blakemore. The discovery was based on the fact that certain

motile, aquatic bacteria orient and migrate along magnetic field lines

when subjected to a magnetic field of the order of the geomagnetic field, or

more. For sensitive to the magnetic field of bacteria (MTB) of the Northern Hemisphere collection

sites, the preferred direction of migration in the drops of water and sediment at the >> << a glass microscope slide parallel to the magnetic field corresponding to the north

migration of the geomagnetic field. The rate of migration of individual bacteria

along the lines of the magnetic field depends on the field, but can be 90% or more

forward speed of swimming cells (which can be up to 150 microns per second
