  1. Staphylococcus saprophyticus on Mannitol Salt Agar (MSA
  2. Mannitol salt agar (MSA) is a selective, differential, and indicator medium that is used to isolate and identify Staphylococcus aureus from the clinical specimen. As its name suggests mannitol salt agar (MSA) contains 1% mannitol (sugar), 7.5% salt, and agar as a solidifying agent
  3. Mannitol Salt Agar (MSA) is used as a selective and differential medium for the isolation and identification of Staphylococcus aureus from clinical and non-clinical specimens. It encourages the growth of a group of certain bacteria while inhibiting the growth of others
  4. Staphylococcus saprophyticus may have the ability to ferment mannitol. It produces yellow hallow around the colonies during mannitol salt agar test resembling with Staphylococcus aureus. Escherichia coli does not grow in the medium while Staphylococcus epidermidis has colorless to pink colonies
  5. Indeed, Mannitol salt positive CoNS (Staphylococcus caprae, S. hemolyticus and S. saprophyticus) have been reported in Nigeria and Japan [13,14]. Thus, in certain settings, if used individually to identify Staphylococcus aureus , common phenotypic tests may be insufficient; some isolates will be misidentified, either as Staphylococcus aureus or CoNS
  6. Mannitol salt agar (MSA) is often used in resources' limited laboratories for identification of S. aureus however, coagulase-negative staphylococci (CoNS) grows and ferments mannitol on MSA. 171 strains of CoNS which have been previously misidentified as S. aureus due to growth on MSA were collected from different locations in Nigeria and two methods for identification of CoNS were compared i.e. ViTEK 2 and MALDI-TOF MS with partial 16S rRNA gene sequencing as gold standard
  7. Direct observation is followed by isolation of the organism from primary clinical specimens on selective culture media like Mannitol salt agar or blood agar supplemented with 5 per cent sheep blood), following an incubation period of 18-24 h in the air at 35-37°C

Staphylococcus aureus and Staphylococcus epidermidis on mannitol salt agar. Mannitol salt agar is a commonly used growth medium in microbiology. It encourages the growth of a group of certain bacteria while inhibiting the growth of others. It contains a high concentration (~7.5%-10%) of salt (NaCl), making it selective for gram positive bacteria. Staphylococci are able to tolerate the high salt concentration found in Mannitol Salt agar and thus grow readily. If mannitol is fermented, the acid produced turns the phenol red pH indicator from red (alkaline) to yellow (acid). positive = acid end products turn the phenol red pH indicator from red to yellow negative = prenol red remains re MANNITOL SALT AGAR PLATE (MSA) Selective for gram-positive bacterium (e.g. Staphylococcus). Mannitol fermentation by pathogenic staphylococci, such as S. aureus and S. simulans. is indicated by the agar media changing from red to yellow. SELECTIVE AGENT: NaCl (salt

Mannitol Salt Agar (MSA) Small pink to red colonies are formed on MSA. The media remains red as the bacterium cannot ferment mannitol. This media is a selective media for S. aureus and is commonly used to distinguish S. aureus from S. epidermidis. 3. Tryptic soy agar (TSA The sensitivity and specificity of the tube coagulase test (human plasma) was markedly improved when Mannitol salt agar and DNase were introduced as a tri-combination test for routine identification of Staphylococcus aureus (100% specificity and 75% sensitivity) The first two tests accomplished were Simmon's Citrate and Mannitol Salt Agar (MSA). Relying on the results from this MSA plate and a positive Nitrate result led to an initial deduction of Staphylococcus aureus. Mannitol broth was then inoculated with the Gram-positive bacteria and a negative result was achieved Staphylococcus epidermidis on Mannitol Salt Agar. Notice the small white colonies that do not use the mannitol; that is, no color change is observed since no acid has been produced Coagulase producing strains of S. aureus form when grown in plasma (tube on the left), whereas coagulase negative staphylococci (S. saprophyticus [middle tube] and S.epidermidis form a clot

Indranil Samanta, Samiran Bandyopadhyay, in Antimicrobial Resistance in Agriculture, 2020. Isolation of staphylococcus. Staphylococci can be isolated in routinely used bacteriological media like nutrient agar, blood agar or specific media like mannitol salt agar (MSA), lipovitellin salt mannitol agar (LSM), Vogel-Johnson agar (VJ), Baird Parker agar, potassium thiocyanate-actidione-sodium. Staphylococcus epidermidis; Staphylococcus saprophyticus; MORPHOLOGY. They are Gram-positive cocci, 0.5-1 µm in diameter, arranged in irregular clusters, singly or in pairs. CULTURAL CHARACTERISTICS. They are facultative anaerobes but grow best in aerobic environment at 35ᵒC - 37ᵒC on blood agar and mannitol salt agar as a selective medium with coagulase test, cultured on mannitol salt agar (MSA), Voges Proskauer (VP) and oxidase test. Bacteria that can be identified and characterized from infected ovary wereStaphylococcus aureus (46%), Staphylococcus intermedius (27%), Staphylococcus epidermidis (20%), dan Streptococcus sp. (7%) Mannitol Salt is a selective bacterial growth medium because it has a very high concentration of NaCl (7.5%). Most bacteria cannot survive in this highly saline, hypertonic environment. But the genus Staphylococcus has a protective slime layerthat protects it in a harsh, salty environment. So Staph grow well in this media Using CLED agar provides advantages of growth-supports of most potential uropathogens including gram-positive cocci such as Staphylococcus aureus, Staphylococcus saprophyticus, and Enterococcus spp. In parallel, Mannitol Salt Agar (MSA) was inoculated for targeting gram-positive UTI growth

Staphylococcus saprophyticus- An Overview Microbe Note

Mannitol salt agar (MSA) is often used in many laboratories in some developing countries, e.g. Nigeria for identification of S. aureus. The initial design of the agar was with the claim that it supports the growth of coagulase positive staphylococci only by being a selective and differential medium: The composition is 7.5% sodium chloride. Mannitol Salt Agar (MSA): is a selective and differential medium. The high concentration of salt (7.5%) selects for members of the genus Staphylococcus, since they can tolerate high saline levels. Organisms from other genera may grow, but they typically grow very weakly. MSA also contains the sugar mannitol and the pH indicator phenol red iv. Mannitol salt agar (fermented by S.aureus but not most of other staphylococci) Biochemical tests: a. Catalaste positive (helps to differentiate between Staphylococcus and Streptococcus) b. Mannitol fermentation test (acid production without gas - usually by Staphylococcus aureus) c. Phosphatase test (S. aureus positive, S epidermidis.

mannitol salt agar, fermentation of mannitol produces a yellow zone around the colony. In addition to mannitol, S. aureuscan metabolize glucose, xylose, lactose, sucrose, maltose, and glycerol. Further differentiation of staphylo-cocci can be achieved by growth in the presence of novo-biocin. Staphylococcus saprophyticus[14] and S. xylosus[5 Staphylococcus epidermidis is salt-tolerant (halophilic) so it will grow on the mannitol salt agar (MSA) Plate and will produce colonies. However, Staphylococcus epidermidis does not have the ability to ferment mannitol, because it lacks the enzyme coagulase. In other words, Staphylococcus epidermis is considered coagulase - or coagulase-negative. Since there is no fermentation, no acidic. Mannitol Salt Agar (MSA) This type of medium is both selective and differential. The MSA will select for organisms such as Staphylococcus species which can live in areas of high salt concentration (plate on the left in the picture below). This is in contrast to Streptococcus species, whose growth is selected against by this high salt agar (plate on the right in the picture below) Although egg yolk mannitol-salt (EYMS) and Baird-Parker agar has been used as a selective medium for S. aureus (Ollis et al., 1995), we used the Baird Parker + RPF agar to detect coagulase after isolation of colonies (Fig. 1).
