Gram staining of an intra-articular aspirate obtained that day from the affected knee showed Gram-variable
15) The Nugent score is calculated by assessing for the presence of large gram-positive rods (Lactobacillus morphotypes; decrease in Lactobacillus scored as 0 to 4), small gram-variable
It consists of facultatively anaerobic, oxidase- and catalase-negative, nonsporing, nonencapsulated, nonmotile, pleomorphic, Gram-variable
Gram stain from the blood culture showed Gram-variable
mixed with Gram-negative rods (later on identified as Aggregatibacter actinomycetemcomitans).
A Changes in vaginal flora, such as a decreasing normal presence of lactobacilli (large gram-positive rods) and an increased presence of other bacteria, particularly Gardnerella vaginalis (gram-negative to gram-variable
pleomorphic rods), is associated with bacterial vaginosis (BV), the most common cause of vaginitis in women of reproductive age.
The Gram-negative or Gram-variable
short rods, transparent colonies, [beta]-hemolytic on human blood agar, catalase-negative, Glucose, Prolin, ONPG positive, were presumptively identified as G.
In this system, large Gram-positive rods (Lactobacillus morphotypes), small Gram-negative to gram-variable
rods (Gardneralla vaginalis and Bacteroides morphotypes) and curved Gram-negative rods (Mobiluncus species) are quantitated and a summation score is obtained.
The culture grew a Gram-variable
bacillus, identified at a reference laboratory as Tsukamurella spp, and a yeast, Trichosporon spp.
We studied the inhibitory effects of these plants against 15 other bacteria; six Gram-negative, six Gram-positive, and three Gram-variable
bacteria (Table 3).
and small curved gram-variable
rods (Mobiluncus spp.
By the second hospital day, both admission blood cultures were growing Gram-variable
bacilli that produced pink-pigmented colonies on blood agar.
The aerobic blood culture bottle of the first sample obtained from the recipient and aerobic cultures of the third erythrocyte unit enabled isolation of the same gram-variable
coccobacilli after incubation for 48 hours (Figure).
