Chromobacterium violaceum is a gram negative oxidase positive bacillus that causes human infections infrequently. It is a normal inhabitant of soil and stagnant water of the tropical and subtropical areas. In humans, it can cause infections ranging from life threatening sepsis with metastatic abscesses to skin infections and urinary tract infections. The organism is notoriously resistant to most cephalosporins and Ampicillin. Fluoroquinolones and aminoglycosides show good in vitro susceptibility. High mortality rates associated with these infections necessitate prompt diagnosis and appropriate antimicrobial therapy. Here we present three cases of Chromobacterium violaceum infection from Government Medical College Kozhikode, Kerala.
Background: Fetal biophysical profile is a well-established method of antepartum surveillance in high risk pregnancy. Classical biophysical profile with all parameters (fetal breathing movements, fetal tone, fetal gross body movements, amniotic fluid volume and non-stress test) needs two phase testing by ultrasound and external Doppler monitor to record fetal heart rate, is more cumbersome, time consuming and expensive.Methods: This study was a prospective clinical study which consisted of 70 patients having pregnancy with high risk factors. The patients were evaluated with the modified biophysical profile consisting of NST recording for 20mins, followed ultrasound assessment of amniotic fluid volume, using four quadrant technique.Results: When the Modified biophysical profile is normal, it gives reassurance that the fetal status is good with good perinatal outcome. When the MBPP is abnormal there is increased incidence of perinatal morbidity as well as mortality.Conclusions: Modified biophysical profile is an effective primary antepartum fetal surveillance test in high risk pregnancies in predicting perinatal outcome.
Production of the crop is affected by deficiency of fertilizers and low number of plant growth promoting rhizobacteria in soil. Pseudomonas fluorescens isolated from soil characterized and evaluated in Arachis hypogaea Pannapatti Salem,Tamil Nadu.Nigella sativa (Kolinji) Periyar University Salem,Tamil Nadu. were isolated and the isolates was named as (PSO1and PSO2)Bio chemical characterized showed that the isolates were acid procedures and positive to catalase and nitrate reductase production and do not have hydrogen sulphide production .The isolates were the amount of phosphate solubilization andsiderophores production by Pseudomonas fluorescens compared to isolates (PS01 and PS02).Maximum activity shows in PS01.The isolates were identified by biochemical test confirmed with genomic DNA identification. Arachis hypogaea seed with Pseudomonas fluorescens PS01 for plant growth promoting activities in green house showed a positive result. This isolates increased Arachis hypogaea leaves number, branches number, root length, and shoot length number of nuts also increased. In conclusion that the use of Pseudomonas fluorescensPS01 isolates could increase the Arachis hypogaea growth and yield performance. This isolates can used as potential bio fertilizers and plant growth promoter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
