First Report of Isolation and Characterization of Aurantimonas altamirensis from Clinical Samples

Phytochemical investigations of fresh leaves and stem bark of Plumeria obtusa Linn. have led to the isolation and characterization of a new iridoid, p-methoxy- E-cinnamoyloxy plumieride (1), to which the trivial name champalinin has been assigned, and a triterpene lactone, 3β-hydroxy-urs-12-one-13β,28-olide (2). This is the first report of compound 2 as a natural product, although it has been reported earlier as a synthetic compound. Identification of these compounds was achieved through spectroscopic studies and chemical transformations.

Isolation And Characterization

Three compouds, (+)-butyrolactone IV (1), butyrolactone I (2) and terrelactone A (3) were isolated from the fungus Aspergillus terreus associated with Apostichopus japonicus from the Yellow Sea in China; their structures were elucidated by spectral methods. Compounds 1 and 2 were shown to have moderate antiangiogenesis activity when tested using the zebrafish assay. This is the first report of butyrolactones with antiangiogenesis activity.

Isolation And Characterization

The genus Dialium belongs to the Caesalpinioideae family, consisting of approximately 30 species distributed in the tropical regions. Secondary metabolites from the Dialium genus have been reported to exhibit various biological activities including antioxidant, cytotoxicity and antimicrobial activities. This work describes the isolation and characterization of five compounds from the leaves of Dialium cochinchinense Pierre. Their structures were established by spectroscopic analysis, including MS and NMR spectra. Accordingly, the isolated compounds were identified to be lupeone (1), b-sitostenone (2), β-sitosterol (3), daucosterol (4), and dihydrokaempferide (5). To the best of our knowledge, this is the first report of the isolation of compounds 1 and 5 from the genus Dialium.

Isolation And Characterization

A total of one hundred five samples were collected from hospitals of Baghdad city during the period from 10/12/2008 to 15/3/2009. These clinical samples included: urine (50) wound swabs (25), sputum (20), and ear swabs (10). These samples were collected from the Baghdad hospital/ Teaching Laboratories, and Al-Yarmook Hospital/ Teaching Laboratories. Twenty six isolates of Proteus mirabilis were characterized according to the morphology and microscopic characteristics, along with the biochemical and confirmatory APi 20 E tests. These isolates were obtained from: urine (19), wound swabs (6), ear swabs (2), and sputum (1). The twenty selected isolates were tested for resistance against ten antibiotics and only urine samples were tested for nalidixic acid and nitrofurantoin resistance. It was shown that there were differences in the antibiotic resistance of isolates. High resistance to nitrofurantoin and ampicillin were found among isolates as (100%) and (75%) respectively while the resistance of Proteus isolates to trimethoprin /sulphamethazol, were (65%). This study also showed that resistance of isolates to gentamicin, ciprofloxacin, ceftazidime, pipracillin, cefotaxime, nalidixic acid azteronam, imipenem and amikacin were (50, 40, 40, 40, 35,27, 20,15, 5)% respectively.
