Ms. Renee Ellmers forgets what she believes, should take early retirement

“Reeling from controversy over her ill-fated radio interview with Laura Ingraham, Rep. Renee Ellmers is claiming she has the “same position” on immigration as Sens. Ted Cruz, Rand Paul, and Mike Lee.”

Apparently, Ms. Ellmers’ forgot that her position is actually different. Click here

Mr. Jeb Bush praises those who break the law, supports government-mandated education

Rather remarkable. It looks as if the opening he sees to run for president is no different than Mr. Jeb Bush’s Democrat opponents.

“In a speech Friday, Former Florida Gov. Jeb Bush praised illegal immigrants as “risk takers” who embody the entrepreneurial spirit of America and doubled down on his defense of Common Core. ” click here

First recorded outbreak due to Cryptosporidium cuniculus

Puleston RL, Mallaghan CM, Modha DE, Hunter PR, Nguyen-Van-Tam JS, Regan CM, Nichols GL, Chalmers RM. The first recorded outbreak of cryptosporidiosis due to Cryptosporidium cuniculus (formerly rabbit genotype), following a water quality incident. J Water Health. 2014 Mar;12(1):41-50. doi: 10.2166/wh.2013.097.

We report the first identified outbreak of cryptosporidiosis with Cryptosporidium cuniculus following a water quality incident in Northamptonshire, UK. A standardised, enhanced Cryptosporidium exposure questionnaire was administered to all cases of cryptosporidiosis after the incident. Stool samples, water testing, microscopy slides and rabbit gut contents positive for Cryptosporidium were typed at the Cryptosporidium Reference Unit, Singleton Hospital, Swansea. Twenty-three people were microbiologically linked to the incident although other evidence suggests an excess of 422 cases of cryptosporidiosis above baseline. Most were adult females; unusually for cryptosporidiosis there were no affected children identified under the age of 5 years. Water consumption was possibly higher than in national drinking water consumption patterns. Diarrhoea duration was negatively correlated to distance from the water treatment works where the contamination occurred. Oocyst counts were highest in water storage facilities. This outbreak is the first caused by C. cuniculus infection to have been noted and it has conclusively demonstrated that this species can be a human pathogen. Although symptomatically similar to cryptosporidiosis from C. parvum or C. hominis, this outbreak has revealed some differences, in particular no children under 5 were identified and females were over-represented. These dissimilarities are unexplained although we postulate possible explanations.

Wastewater treatment in an Indonesian village

HS Lim, SE Bramono. Community-based wastewater treatment systems and water quality of an Indonesian village. J Water Health. 2014 Mar;12(1):196-209. doi: 10.2166/wh.2013.003.

This paper examines the impact of community-based water treatment systems on water quality in a peri-urban village in Yogyakarta, Indonesia. Water samples were taken from the wastewater treatment plants (WWTPs), irrigation canals, paddy fields and wells during the dry and wet seasons. The samples were tested for biological and chemical oxygen demand, nutrients (ammonia, nitrate, total nitrogen and total phosphorus) and Escherichia coli. Water quality in this village is affected by the presence of active septic tanks, WWTP effluent discharge, small-scale tempe industries and external sources. We found that the WWTPs remove oxygen-demanding wastes effectively but discharged nutrients, such as nitrate and ammonia, into irrigation canals. Irrigation canals had high levels of E. coli as well as oxygen-demanding wastes. Well samples had high E. coli, nitrate and total nitrogen levels. Rainfall tended to increase concentrations of biological and chemical oxygen demand and some nutrients. All our samples fell within the drinking water standards for nitrate but failed the international and Indonesian standards for E. coli. Water quality in this village can be improved by improving the WWTP treatment of nutrients, encouraging more villagers to be connected to WWTPs and controlling hotspot contamination areas in the village.
