Diagnosis is clinical and confirmed by culture. Treatment is with ceftriaxone, ciprofloxacin, or azithromycin. Gram-negative bacteria are a specific type of bacteria with unique characteristics. Like most bacteria, they can cause infections throughout the body. Common infection sites include the lungs, urinary tract, bloodstream, nervous system, and soft tissues. Surgical wounds can also become infected with gram-negative bacteria.

Characteristics of Gram-negative bacteria Gram-negative Bacilli. ENTEROBACTERIACEAE is a large family of bacteria that consists of more than two dozen genera. As a group they are commonly called enterics. They typically inhabit the colon of warm-blooded animals as normal flora. However, various strains of these bacterial groups can cause severe gastrointestinal disease. 2010-04-01 · Monotherapy with aztreonam appears to be as effective as combination of a beta lactam and an aminoglycoside (Netspan) for the treatment of patients with documented Gram negative sepsis 34.

The rest of the Gram-negative infections are being caused by other Gram-negatives, including Enterobacter species, Acinetobacter, Stenotrophomonas maltophilia, non-aeruginosa Pseudomonas species, Alcaligenes species, and a variety of other emerging Gram-negatives. One postulate is that febrile conditions result in the sequestration of soluble iron, effectively starving some pathogens of that essential nutrient. On the basis of our recent experiments, we propose a new mechanism for how fever serves to restrict a wide range of Gram-negative bacteria. The elevated temperature prevents the bacteria from synthesizing their protective LPS, thereby enabling serum complement to perforate and kill the invading pathogens even prior to the production of host Examples of these are Gram-negative bacteria that cause septicaemia, meningitis and conges- tive heart disease. If fever indeed exerts a general role in the control of bacterial infections, we must wonder how the Cram-poskive bacteria re- main resistant to febrile conditions (Mackowiak and Marling-Cason, 1983). The beneficial effects of fever include reduced bacterial proliferation, particularly in association with iron deprivation [12], and may be involved in membrane homeostasis during infection [13].Febrile body temperature restricts a wide range of Gram-negative bacteria from synthesizing their protective lipopolysaccharides and thereby enables serum complement to perforate and kill the invading pathogens [14].The reduction of bacterial loads seems, however, not primarily be achieved by the Conclusions: Although Gram-negative bacteria are the most common etiology of fever in neutropenic patients, the occurrence of infections caused by coagulase-negative Staphylococcus and molds has been increasing in comparison with the observations from previous studies in King Chulalongkorn Memorial Hospital.
