The antibacterial activity of essential oils extracted from medicinal plants (Ocimum gratissimum, L., Cybopogum citratus (DC) Stapf., and Salvia officinalis, L.) was assessed on bacterial strains derived from 100 urine samples. Samples were taken from subjects diagnosed with urinary tract infection living in the community. Microorganisms were plated on Müller Hinton agar. Plant extracts were ap...

In today’s largely populated modern world, crop yield is becoming increasingly important. To increase yield, new technologies for farming are continuously being innovated. The aim of this study the identification Plant Growth Promoting Bacteria (PGPBs) and their properties. order to conduct experiment, soil samples were collected from community garden LEAF (Local Ecology Agriculture Fremont). T...

Bacterial urease, particularly from Proteus mirabilis, has been implicated as a contributing factor in the formation of urinary and kidney stones, obstruction of urinary catheters, and pyelonephritis. Weekly urine specimens (n = 1,135) from 32 patients, residing at two chronic-care facilities, with urinary catheters in place for greater than or equal to 30 days yielded 5,088 phenotypically and ...

After sudden death with a history of about two weeks ruminal tympany, a 3-year-old, male alpaca from Huantaiqi Zoo, Chongqing, China was presented to the Animal Diseases Rapid Diagnosis Center, Southwest University, Chongqing, China for diagnosis of the death causes. At necropsy, the primary pathological lesions were found in the lung. A pronounced hemorrhage with topical congestion and lobular...

OBJECTIVES We analysed the architecture and probable origin of a class 1 integron from cefotaxime-resistant Morganella morganii isolates. METHODS bla genes and class 1 integron elements were detected by PCR and DNA-DNA hybridization in a M. morganii strain isolated in 1996. PCR-mapping and sequencing of different fragments were carried out to determine the integron's architecture. RESULTS A...

To infect a susceptible host, the gastrointestinal pathogen Yersinia enterocolitica must survive passage through the acid environment of the stomach. In this study, we showed that Y. enterocolitica serotype O8 survives buffered acidic conditions as low as pH 1.5 for long periods of time provided urea is available. Acid tolerance required an unusual cytoplasmically located urease that was activa...

An efficient method for the synthesis of a new series α-aminophosphonates has been developed in one-pot Kabachnik-Fields reaction 4-methylaminophenol with various aldehydes and triethylphosphite under microwave irradiation neat conditions using ZnO nanoparticles as reusable heterogeneous catalyst, 82-93% yield at 250 Hz within 2-5 min. A single crystal studied compound 3e was selected X-ray dif...

This study was performed to investigate the inhibitory effects of brown algae extracts on histamine production in mackerel muscle. First, antimicrobial activities of brown algae extracts against Morganella morganii were investigated using a disk diffusion method. An ethanol extract of Ecklonia cava (ECEE) exhibited strong antimicrobial activity. The minimum inhibitory concentration (MIC) of ECE...
