Pseudomonas aeruginosa infections pneumonia

Meropenem (Merrem IV) inhibits syndiesis of die bacterial cell wall and causes die deadi of susceptible cells. This drug is used for intra-abdominal infections caused by Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, and odier susceptible organisms Meropenem also is effective against bacterial meningitis caused by Neisseria meningitidis, Streptococcus pneumoniae, and Hemophilus influenzae. 

The urinary pathogens in complicated or nosocomial infections may include E. coli, which accounts for less than 50% of these infections, Proteus spp., Klebsiella pneumoniae, Enterobacter spp., Pseudomonas aeruginosa, staphylococci, and enterococci. Candida spp. have become common causes of urinary infection in the critically ill and chronically catheterized patient. 

Intra-abdominal infections Complicated appendicitis and peritonitis caused by viridans group streptococci, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Bacterioides fragilis, Bacterioides thetaiotaomicron, and Peptostreptococcus sp. 

Urinary tract infections Urinary tract infections (complicated and uncomplicated), including pyelonephritis and cystitis (initial and recurrent) caused by Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Enterobacter cloacae, Klebsiella oxytoca, Citrobacter sp., and Serratia marcescens. 

Levofloxacin (1), the levo-isomer or the (5)-enantiomer of ofloxacin, received FDA approval in 1996 (Fish, 2003 Hurst et al., 2002 Mascaretti, 2003 Norrby, 1999 North et al., 1998). The initial approval covered community-acquired pneumonia, acute bacterial exacerbation of chronic bronchitis, acute maxillary sinusitis, uncomplicated skin and skin structure infections, acute pyelonephritis, and complicated urinary tract infections (North et al., 1998). Four years later, the levofloxacin indication list grew to include community-acquired pneumonia caused by penicillin-resistant Streptococcus pneumoniae. In addition, in 2002, nosocomial (hospital-acquired) pneumonia caused by methicillin-susceptible Staphylococcus aureus, Pseudomonas aeruginosa, Serratia marcescens, Haemophilus influenzae, Kliebsella pneumoniae, and Escherichia coli was added (Hurst et al., 2002). Finally in 2004, LVX was approved as a post-exposure treatment for individuals exposed to Bacillus anthracis, the microbe that causes anthrax, via inhalation (FDA, 2004). 

Other infections caused by E. coli, K. pneumoniae, Enterobacter, Salmonella typhi, N. gonorrhoeae, N. meningitidis, H. influenzae, H. ducreyi, Shilgella, Vibrio cholerae. Pseudomonas aeruginosa. Staph, aureus etc. 

Use of contact lenses increases the risk of corneal infection. The most common pathogens that cause eye infection are Pseudomonas aeruginosa, Serratia marcescens, Staphylococcus aureus, S. epidermidis, and S. pneumoniae. Fungi rarely cause eye infections. Commonly used disinfectants are benzalkonium chloride and chlorhexidine. 

Outbreaks of disease have been caused by those with artificial fingernails. In 2004 there was an outbreak of Klebsiella pneumoniae among premature babies in a US intensive care unit, caused by bacteria from a nurse s artificial nails. A few years previously it was Pseudomonas aeruginosa that threatened several newborn babies in a New York hospital and this was traced to the same cause. In Canada three patients who had had surgery on their spinal cord developed Candida infections of the spinal disks and this was traced to an operating theatre technician who had artificial nails. An intensive care unit in Oklahoma City saw 16 patients die as a result of contracting Pseudomonas aeruginosa from two nurses who had artificial nails. Thankfully such outbreaks are now extremely rare. 

Endometritis in mares may be associated with at least four clinical s)mdromes. It can be caused by sexually transmitted infections, such as Taylorella equigenitalis (contagious equine metritis). Pseudomonas aeruginosa and Klebsiella pneumoniae. Pseudomonas and Klebsiella spp. may also be present in the fecal and genital flora. Chronic uterine infection with Streptococcus equi subsp. zooepidemicus and Escherichia coli are often associated with contamination of the uterus by fecal and genital flora. 

They are generally toxic to most body tissues, and are less potent than exotoxins. They are typified by the following, Escherichia coli (wound infection and septicaemia), Klebsiella pneumoniae (urogenital tract infections). Shigella dysenterlae (dysentery). Salmonella typhosa (typhoid fever), Pasteurella pestis (bubonic plague) and Pseudomonas aeruginosa (wound infections and septicaemia). Not all of these endotoxins are fully characterized, and some toxic mechanisms are obscure.
