This review concerns plant pathogenic bacteria, which are strictly restricted either to the sieve tubes in the phloem or to the vessels in the xylem. These bacteria are endogenous as opposed to exogenous bacteria such as species of Erwinia , Pseudomonas , Ralstonia or Xanthomonas , which colonize the apoplast (intercellular spaces) of plant tissues, even though some of the exogenous bacteria, s...

Diabetes mellitus is a metabolic disease and one of the most feared complications is diabetic foot ulcers (DFUs) resulting in amputation and gangrene arising from the action of pathogenic bacteria. This study investigated the efficacy of essential oil extracts of Curcuma longa (turmeric) and Syzygium aromaticum (clove) on bacteria implicated in DFUs. Essential oils extracted from Curcuma longa ...

Objective: Main aim of the present study was to determine differential effects of temperature and pH on the sensitivity/resistance of bacteria against ciprofloxacin and chloramphenicol. Methods: Both the bacterial strains were subjected to MIC determination. These were subjected to the varying values of environmental stresses including temperature and pH. The growth was monitored using spectrop...

When the supply of beneficial mutations limits adaptation, bacterial mutator alleles can reach high frequencies by hitchhiking with advantageous mutations. However, when populations are well adapted to their environments, the increased rate of deleterious mutations makes hypermutability selectively disadvantageous. Here, we consider a further cost of hypermutability: its potential to break down...

Several pathogenic or opportunistic bacteria have the ability to either induce or inhibit host cell apoptosis. The capacity to modulate cell pathways that result in the induction or delay of host cell apoptosis is considered to be an important bacterial virulence mechanism. These processes could be mediated by different host cell signaling pathways that are subverted by the bacteria. Pathogens ...

In the present investigation of the human pathogenic bacteria such as Escherichia coli, and Pseudomonas fluorescens, Salmonella typhi, and Klebsiella pneumoniae, were analysed the ozone treatment by using ozonizer M221. To optical density was control and treated cultures were measured and to the different time intervals such as 5, 10 and 15 minutes of the optical density (by use of a digital sp...

We studied the conditions necessary for optimal recovery of bacteria from cerebrospinal fluid. Our results indicated that Streptopcoccus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae can be quantitatively recovered in the sediment after centrifugation at 1,500 X g for 15 min. Equivalent numbers of bacteria were recovered by centrifugation or filtration of antibiotic-free cerebr...
