Acinetobacter baumannii-calcoaceticus complex (ABC) organisms are gram-negative bacteria found in soil and water . Specific and Selective Bacteriophages in the Fight against Multidrug-resistant Acinetobacter baumannii. AFLP uses selective amplification of DNA fragments secondary to restriction and nuclease digestion. Most Acinetobacters are infectious, and the strain A.baumannii is the most common nosocomial infection in health care centers and military medical facilities. Acinetobacter kyonggiensis, which has an optimum growth temperature of 28 °C, is exceptional. Acinetobacter spp. All samples were cultured on blood agar and MacConkey agar (Oxoid Co. England). Principles and Practice of Pediatric Infectious Diseases (Fifth Edition), Mandell, Douglas, and Bennett's Principles and Practice of Infectious Diseases (Eighth Edition), Amplified fragment-length polymorphism (AFLP), Repetitive extragenic palindromic PCR (rep-PCR), Electrospray ionization mass spectrophotometry (ESI-MS). The rate of colonization with Acinetobacter spp. Acinetobacters are not fastidious, and all species grow well on common all-purpose media, such as TSA and PCA, and on minimal media containing single carbon and energy sources. To identify the isolates of A. baumannii, the preliminary conventional phenotypic tests including growth on MacConkey agar, sugar fermentation, motility, catalase and oxidase tests, and other standard recommended tests [ 23 , 24 ]. Its discriminatory power is high, and digitalization of data lends itself to computerized analysis. 2001 Winter;2(4):253-4. doi: 10.1089/10962960152813287. Samples were collected from 916 patients, which have shown bacterial growth on MacConkey and blood agar culture media. DOI: 10.15406/jmen.2015.02.00046 MLST has been shown to be highly concordant with PFGE and is reproducible between laboratories. ... sample swabs obtained from Field Hospital Baghdad were streaked across BBL trypticase with 5% sheep blood and BBL MacConkey agar (Becton Dickinson) and incubated at 35°C for 18–24 h. All other sample swabs were streaked across BBL MacConkey agar and … The polysaccharide capsule also protects bacterium from dehydration Tortora et al (1998). Isolates of A.baumannii which … They cause opportunistic infections only in people with compromised immune status or with an indwelling device, or both. A. baumannii is a mildly virulent organism that becomes resistant to antimicrobials. It has the ability to survive on environmental surfaces for months, making transmission difficult to control. Indeed, biochemical test kits are generally unable to distinguish between the ABC-complex species and these are all generally identified as A. baumannii. Acinetobater growth on MacConkey agar #Acinetobacter #MacConkeyagar #ABC. Advancements in sequencing technology have made this technique more readily available to many laboratories. BMC Complement Med Ther. Samples were collected from 916 patients, which have shown bacterial growth on MacConkey and blood agar culture media. eCollection 2017. Acinetobacter, nonmotile rod. do not grow on MacConkey agar or may show hemolysis on sheep blood agar (A. haemolyticus, Acinetobacter genomic species 6, 13BJ, 14BK, 15BJ, 16 and 17). They are able to survive on moist and dry surfaces, and also be present in foodstuff and on the healthy human skin. A prospective observational study was performed on the intensive care units (ICUs) of the national referral hospital in Jakarta-Indonesia, in 2013 and 2014. Species of the genus Acinetobacter, except some of the A. lwoffii strain, grow very well on MacConkey agar. ; Careful attention to infection control procedures, such as hand hygiene and environmental cleaning, can reduce the risk of transmission.
