During the study period, of total specimens n=12126, bacterial growth was obtained in 35.9% (n=4361) samples of which 40.5% (n=1770) were Gram-negative rods
and light growth of a gram-negative rod
. In a subsequent attempt to identify the unknown gram-negative rod
by VITEK 2 (bioMerieux Inc., Durham, NC, USA), the results suggested Brucella spp.
Studies suggest that this integron can be seen in 22-59% of gram-negative rods
, especially K.
Hollis, "Acinetobacter, Achromobacter, Chryseobacterium, Moraxella, and other nonfermentative gram-negative rods
Samples with morphology consistent with Gram-negative rods
were transferred to EMB Teague Agar (Merck), whereas those suggestive of Staphylococcus spp.
Pathogenic gram-negative rods
have been cultured from neckties, scrubs, uniforms, and white coats in multiple studies, he added.
Two different Gram-negative rods
were recovered from endotracheal aspirate cultures of distinct hospitalized patients, in the same period, at a neurological intensive care unit (ICU).

and Gram-negative rods
have also been isolated as additional flora (Malinowski et al., 2011).
(2,15) The number of each of the following was quantified and recorded: gram-positive cocci, gram-positive rods, gram-negative cocci, gram-negative rods
, yeast, hyphae, white blood cells, and red blood cells.
In accordance with the previous studies on sandflies, our results showed a predominance of gram-negative rods
. There are reports about the possible negative role of gram-negative bacteria on the development of parasites in the mosquitoes' gut (12).
All four blood cultures (two aerobic and two anaerobic bottles) were reported as positive for gram-negative rods
at 28 hours, and by culture day four, the organism was identified as Eikenella corrodens.
