They are Gram-positive rods or cocci with a microaerophilic metabolism and produce lactic acid as the main fermentation end product, either alone (homofermentative LAB) or together with carbon dioxide and ethanol or acetic acid (heterofermentative LAB). ...

Positive Gram stain results usually include a description of what was seen on the slide. This typically includes: Whether the bacteria are Gram-positive (purple) or Gram-negative (pink) Shape — round (cocci) or rods (bacilli) Size, relative quantity, and/or arrangement of the bacteria, if...
H. alvei organisms are small Gram-negative rods that form small, smooth, transparent, lactose-negative colonies. On URI Chromogenic agar, the H. alvei produced small greenish colonies. H. alvei produces uniform turbidity of the nutrient broth. We selected card type N222 for antibiotic susceptibili...
See Urine AnalysisCharacteristics of Gram Negative BacteriaAs with Gram positive bacteria, Gram negative bacteria also contain the peptidoglycan polymer in their cell wall. While this polymer is thin (2 to 4 nanometers in thickness with just about 3 layers of peptidoglycan) in Gram negative ...

positive bacteria than gram-negative ones, in this review, we presented natural products with anti-gram-negative bacteria and their mechanisms of action. Phenolic compounds, terpenoids, alkaloids and organosulfur compounds are among the most important classes of antimicrobial natural products and are ...
The accuracy of the test was assessed using specificity, sensitivity, positive and negative predictive values as measures. Results Out of 100 GNB, 77 isolates were obtained from urine specimens, 10 isolates from pus specimens, 6 isolates from sputum, 5 isolates from blood, and 2 isolates from ...
Several genera of nonglucose-fermenting gram-negative rods are infrequent opportunistic human pathogens. As a group, most are nonfastidious, aerobic, catalase-positive organisms; motility, oxidase activity, and growth on MacConkey agar are variable. Those organisms that grow on MacConkey ...
