The sources of water supply for drinking and other domestic uses available to the rural population of Mutenda was analysed bacteriologically by standard techniques (Presumptive and Differential Coliform tests (Wilson et al 1935), Ministry of Health (1946). The water sources include wells, bore holes, springs and rivers. Assessment of suitability by standard criteria showed that, the bore hole water was the only source of supply bacteriologically safe for drinking. The need for further research on the microbiology of surface and underground water resources is stressed. Reassessment of the standards for water quality, which have largely been based on the experience from waters in temperate, more developed countries and development of suitable tests for sound epidemiological studies to establish realistic standards applicable to the developing countries is advocated.

Proteins' flexibility is a feature in communicating changes in cell signaling instigated by binding with secondary messengers, such as calcium ions, associated with the coordination of muscle contraction, neurotransmitter release, and gene expression. When binding with the disordered parts of a protein, calcium ions must balance their charge states with the shape of calcium-binding proteins and their versatile pool of partners depending on the circumstances they transmit. Accurately determining the ionic charges of those ions is essential for understanding their role in such processes.

Background: Sycamore tree-derived hypoglycin A (HGA) toxin causes atypical myopathy (AM), an acute, equine pasture-associated rhabdomyolysis but incidence fluctuates.
Objectives: Investigate whether tree or environmental factors influence HGA concentration in sycamore material and are associated with AM relative risk.

Inflammatory bowel disease (IBD) is a complex gastrointestinal disorder attributed to genetic and environmental factors. Microcystin-leucine-arginine (MC-LR) is an environmental toxin that accumulates in the gut and produces intestinal damage. The aim of this study was to investigate the effects of exposure to MC-LR on development and progression of IBD as well examine the underlying mechanisms of microcystin-initiated tissue damage.

Catabolic plasmids are critical factors in the degradation of recalcitrant xenobiotics, such as dioxins. Understanding the persistence and evolution of native catabolic plasmids is pivotal for controlling their function in microbial remediation. Here, we track the fitness and evolution of Rhodococcus sp.

Irrigation rapidly expanded during the 20 century, affecting climate via water, energy, and biogeochemical changes. Previous assessments of these effects predominantly relied on a single Earth System Model, and therefore suffered from structural model uncertainties. Here we quantify the impacts of historical irrigation expansion on climate by analysing simulation results from six Earth system models participating in the Irrigation Model Intercomparison Project (IRRMIP).
