Disease relevance of Gram-Positive Rods

• MIC50 and MIC90 values of ciprofloxacin against Corynebacterium, including group JK, and anaerobic gram-positive cocci were 1 and 8 mg/liter, respectively, and against anaerobic gram-positive rods, were 2 and 16 mg/liter, respectively [1].
• The combination of sulbactam and ampicillin was much more effective than ampicillin alone against Bacteroides fragilis strains but did not differ substantially from ampicillin alone against Fusobacterium spp., gram-positive rods, and gram-positive cocci [2].
• Two strains with elongated gram-positive cocci from colonies on agar showed small gram-positive rods when grown in thioglycolate broth and were physiologically identified as Lactobacillus confusus [3].
• Degradation of arginine and other amino acids by butyrate-producing asaccharolytic anaerobic Gram-positive rods in periodontal pockets [4].

High impact information on Gram-Positive Rods

• A low cerebrospinal fluid glucose level has been reported, with gram-positive rods often noted on the gram stain of the cerebrospinal fluid in severely affected patients [5].
• Of 60 isolates previously sent to the FDOH laboratory, 56 were endospore-forming gram-positive rods and only 7 grew on mannitol-egg yolk-polymyxin B agar and/or the Anthracis chromogenic agar [6].
• The organisms designated as Center for Disease Control group JK are gram-positive rods that have previously been described as causing serious infection in compromised hosts [7].
• It is recommended that if on Gram's stain of the anterior chamber fluid, Gram-positive rods are seen, chloramphenicol should be administered in addition to penicillin because of the possibility of B cereus infection [8].
• The isolates, LIP1 and MW8, were characterized as spore-forming, Gram-positive rods, capable of fermenting glycerol [9].

Chemical compound and disease context of Gram-Positive Rods

• Other species of oral gram-positive rods were not agglutinated by mannose solutions [10].
• All 5 strains were Gram-positive rods, and all utilized formate, glucose and CO [11].
• The predisposing conditions associated with the isolation of non-sporing anaerobic gram-positive rods were previous surgery, malignancy, steroid therapy and immunodeficiency [12].
• Recovery of sorbitol-fermenting bifidobacteria was complicated by high background levels of Gram-positive rods and cocci [13].
• In order to investigate the efficacy of treatment for UTI secondary to gram-positive rods, we performed a non-comparative study on the effect of cefotaxime in 64 patients with gram-positive UTI [14].

Biological context of Gram-Positive Rods

• The second, third and fourth group of identified MAR phenotypes were, in order to importance, gram-negative non-fermentative rods, gram-positive rods and gram-negative fermentative rods [15].

Gene context of Gram-Positive Rods

• Therefore, the desialylation of IgA1 by oral gram-positive rods may facilitate the proteolytic activities of other oral bacteria, and the concerted action may positively influence the survival of the bacteria in the oral community [16].
• Carbohydrate depletion of immunoglobulin A1 by oral species of gram-positive rods [16].
• The cecal flora of the adult White Leghorn hens tested was observed to be composed of 23% G+ (gram-positive) rods, 24% G- (gram-negative) rods, 26% G+ cocci, 9% G- cocci, and 18% G+ coccal-bacilli [17].
• Median total counts of cultivable bacteria were low (< 20), the majority being catalase-positive, Gram-positive cocci and Gram-positive rods, presumably skin bacteria [18].
