After more than 20 tough days, they obtained the primary data of flora, vegetation, hydrology and landforms that revealed the true features of the desert for the first time.
Two categories of microorganisms are required for cheese-making: primary and secondary flora (Salque et al. 2013).
Rhinos, tigers and elephants are listed as endangered under the Convention on International Trade in Endangered Species of Wild Fauna and Flora, the primary international treaty on wildlife.
VAP was classified pathogenically, according to throat flora, as primary endogenous, secondary endogenous or exogenous [ 25].
The action of intestinal bacterial flora on primary bile acids results in the formation of secondary bile acid species: deoxycholic and lithocholic acids, derived from cholic acid and chenodeoxycholic acid, respectively (2).
The placebo-treated patients exhibited the same mix between normal flora and primary pathogens at all three sampling points (0, 6 and 12 months; see online supplementary figure S4, panel C).
Table 3 presents the microorganisms responsible for VAP (18 Gram-negative bacilli and 11 Gram-positive cocci) and the pathogenesis of VAP according to oropharyngeal flora (nine primary endogenous, 18 secondary endogenous and two exogenous).
The infections were classified based on thorat flora as: primary endogenous (PE), caused by germs that were already colonizing the throat on ICU admission; secondary endogenous (SE), caused by germs that were not colonizing the throat on ICU admission but were acquired during the stay in the ICU; and exogenous (EX), caused by germs that were not colonizing the throat.
In the HME group we found 13 patients with VAP caused by Gram-negative bacilli and eight patients with VAP caused by Gram-positive cocci; the pathogenesis of VAP according to oropharyngeal flora was primary endogenous in eight cases, secondary endogenous in 12 cases, and exogenous in one case.
