SCI. 28/01/20 Influence of Dietary Zinc, Copper, and Manganese on the Intestinal Health of Broilers Under Eimeria Challenge. Introduction Coccidiosis is an enteric disease caused by protozoa of the genus Eimeria that affects several animal species, including poultry.
Eimeria multiplication in the intestinal epithelium leads to enterocyte destruction and severe tissue damage, which negatively affects poultry health and welfare status (1). Although difficult to predict, researchers have estimated that the loss in productivity induced by clinical and subclinical coccidiosis in poultry, together with the expenses in prevention and treatment, cost to the industry an excess of US$ 2 billion annually (2, 3). Besides increasing the susceptibility to NE, coccidiosis also leads to changes in the overall structure of the intestinal microbiota (4, 5).
Wu et al. (5) demonstrated a reduction in the cecal microbial diversity following Eimeria infection, and reduction of many members of the family Ruminococcaceae.

NEW PHYTOLOGIST 01/11/17 Manganese distribution and speciation help to explain the effects of silicate and phosphate on manganese toxicity in four crop species. Introduction Manganese (Mn) was first shown to be essential for plant growth by McHargue (1922), later studies showing that Mn deficiency rapidly decreases photosynthesis and O2 evolution (Nable et al., 1984; Schmidt et al., 2016).
Manganese is required also in respiration, Chl biosynthesis, and as a component or cofactor in many enzyme families (Millaleo et al., 2010; Broadley et al., 2012). Plant roots absorb soil solution Mn2+ (Mulder & Gerretsen, 1952), the concentration of which results from a complex interplay between Mn minerals, soil pH, redox status, temperature and microbial activity (Lindsay, 1979; Sparrow & Uren, 2014).

Neurotoxicology. 2017 Sep 16. Changes in water manganese levels and longitudinal assessment of intellectual function in children exposed through drinking water.
Highlights Longitudinal assessment of relations between Mn exposure from tap water and IQ.
Higher water Mn levels are associated with lower IQ in girls. Higher water Mn levels are associated with higher IQ in boys at adolescence. Decreased IQ scores in participants whose water Mn increased between examinations. Abstract Background Manganese is commonly found in water but potential neurotoxic effects from exposure through drinking water are poorly understood. Objective For this follow-up study, we aimed to re-assess the relation between exposure to Mn from drinking water and IQ at adolescence.
Methods From the 380 children enrolled in the baseline study, 287 participated to this follow-up study conducted in average 4.4 years after. Results The mean age at follow-up was 13.7 years (range, 10.5 to 18.0 years). Conclusion. PHYS_ORG 24/08/17 Manganese in underground drinking water is cause for concern. Underground drinking water sources in parts of the U.S. and three Asian countries may not be as safe as previously thought due to high levels of manganese, especially at shallow depths, according to a study led by a researcher at the University of California, Riverside.
Manganese, a metal that is required by the body in tiny amounts, can be toxic at elevated levels, particularly in children. Samantha Ying, an assistant professor of environmental sciences in UCR's College of Natural and Agricultural Sciences, led the study, which was published recently in Environmental Science & Technology.
The paper describes manganese levels that exceed World Health Organization (WHO) guidelines in groundwater wells in Bangladesh, Cambodia, China, and the Glacial Aquifer, which spans 26 states in the northern U.S. and provides drinking water to more than 41 million Americans. Of the four regions, the Glacial Aquifer had the fewest contaminated wells. Explore further: Friend or foe? Neurotoxicology. 2017 Jul 15. pii: S0161-813X(17)30154-7.

We report the case of a 30-year-old Eastern European man who presented with a two-year history of gait disturbance.
Initial neurological assessment revealed hypophonia, hypomimia, mild bradykinesia and rigidity with no resting tremor. His eye movements were normal. A cognitive and neuropsychological evaluation was unremarkable. His gait showed a slight forward tilt of the trunk from his hips on standing and he held his arms slightly abducted from his sides when walking, with reduction of the arm swing.
He tended to walk on the balls of his feet when going forward, seemingly falling forward into the next stride.

This is not an assumption, but a basic idea of the findings of scientists from all over the world. The last two centuries have witnessed the indiscriminate development and overexploitation of natural resources by man causing alterations and impairment of our own environment. Environmental contamination is the result of the irrational use of resources at the wrong place and at the wrong time. Environmental contamination has changed the lifestyle of people virtually all over the world, and has reduced the extent of life on earth.
