They are found in soil or associated with plants and have been used to convert wine to vinegar. Asaia spp. include a group of pink-pigmented gram-negative rods. Colonies are pale pink with scant to moderate growth on sheep blood agar, and they are oxidase negative. Relevant ...
Infections caused by bacterial isolates harboring these enzymes are difficult to treat with carbapenems being the sole effective treatment option for such infections. The objective of this study was to determine the frequency of ESBLs and AmpC-producing Gram-negative bacilli isolated from clinical ...
It is also usually performed when the result of a culture is positive, on a sample of the bacteria grown in the culture. Test results are reported promptly to help guide treatment. What does the test result mean? A negative Gram stain is often reported as “no organism seen.” This ...

However, more recently, an increase in the frequency of bacteremias caused by gram-negative rods has been reported in many centers worldwide, with gram-negative pathogens becoming either predominant or at least as frequent as gram-positive pathogens. This trend has been observed also in the ...
Materials and methods: During the study period, 1569 patients underwent consecutive kidney transplantation in two transplantation centers. We studied the demographics, clinical characteristics, and urine culture data from kidney recipients with MDR/XDR Gram-negative UTIs, and verified the risk factors ...

Since then he had several exarcerbations with gram-negative rods that were reported to be Pseudomonas spp, P. aeruginosa or P. cepacia. In November 1998, the strain was sent for further differentiation to a reference laboratory, which reported Burkholderia pseudomallei. API20NE and 16sRNA PCR ...
