Effects of subminimal inhibitory concentrations of ampicillin on hemagglutination of Escherichia coli.
نویسندگان
چکیده
The hemagglutination (HA) activity of Escherichia coli was enhanced by subminimal inhibitory concentrations (sub-MICs) of ampicillin. One half of the MIC of ampicillin caused a bacterial filamentation and diminished bacterial piliation (as observed by light and electron microscopies) as well as an increase of HA activity. HA activity, however, decreased after separation of ampicillin-treated bacteria. These results indicate that the increase in HA activity by ampicillin is mainly due to filament formation.

Suppression of polymorphonuclear leukocyte chemotactic factor production in Propionibacterium acnes by subminimal inhibitory concentrations of tetracycline, ampicillin, minocycline, and erythromycin.
Propionibacterium acnes is the cause of inflammation in acne vulgaris and has been shown to produce potent neutrophil chemoattractants. Different strain of P. acnes that were sensitive or resistant to ampicillin, erythromycin, minocycline, and tetracycline were grown in the presence of subminimal inhibitory concentrations of the drugs, and their culture supernatants were assayed for neutrophil ...
متن کاملIdentification of β-Lactamase-Negative-Ampicillin Resistance Strains of Escherichia coli in 150 Isolates from Urinary Tract Infection and Fecal Flora in Kerman
β-lactamases are enzymes which inactivate the β-lactam antibacterial agents and are one of the major causes of resistance against these drugs. Recently there are reports on the isolation of bacteria which does not produce β-lactamase, but are resistant to penicillins. In the present study, β-laclamase production was determined using iodometric method on 150 ampicillin resistance Escherichia col...

Entrohemorrhagic Escherichia coli is a human pathogen that causes hemorrhagic colitis due to its verotoxin. It is an agent with food poisoning importance; a significant number of cases subsequntly develop hemolitic uremic syndrome (HUS) which is probably the most common cause of renal failure in childeren and occasionally resulting in death. Inhibition of bacterial growth in food is the most im...

Background: Because of increasing resistance to current antibiotics, many attempts have been made by the researchers to find new compounds of plant derivatives as substitute for non-effective antibiotics. This research was performed to study the antibacterial properties of aquatic and alcoholic extracts of thyme on the clinical and standard strains of enterohemorrhagic Escherichia coli. Materi...
