交沙霉素等四种药物对雏鸡隐孢子虫病的预防效果

对经口感染(4.0×10~5个/鸡)贝氏隐孢子虫(Cryptosporidium baileyi)卵囊的雏鸡在其饲料中分别添加交沙霉素(4.0g/kg)、复方新诺明(4.9g/kg)、大蒜素(400mgkg/)、甲硝唑(2.0g/ks),任鸡自由采食,连用7d.结果表明,实验鸡潜隐期延长,粪中卵囊数显著降低,体重明显增加,血液学值及血清酶学指标与健康对照鸡无明显差异.由此证明,这4种药物对实验性雏鸡隐孢子虫病有不同程度的预防作用.

Impact of Mastitis Control Measures on Milk Production and Mastitis Indicators in Smallholder Dairy Farms in Kiambu District,Kenya

Bovine mastitis and mastitis control were investigated on smallholder farms in central Kenya. After an initial observational study, a clinical trial to assess the impact of three different mastitis control strategies – (1) improved udder hygiene, (2) treatment of subclinical cases, and (3) a combination of these – was conducted on 100 randomly selected farms with 332 lactating cows. Before the implementation of control measures, the milk yield was low (mean 6.5 kg/day; median 6 kg/day) and somatic cell counts (SCC) were high, with 80% and 43% of cows having milk with SCC greater than 250×10³ cells/ml and 600×10³ cells/ml, respectively. Infectious pathogens were also commonly isolated, with 63% of cows being positive for pathogenic bacteria. Neither intervention strategy alone had any effect on mastitis indicators or milk yield. In combination, the measures had some impact, lowering the prevalence of contagious pathogens by 18%, but this was not reflected in a significantly increased milk yield, lowered SCC or reduced incidence of clinical mastitis.

Multiplying possibilities: A postdevelopment approach to hygiene and sanitation in Northwest China

Postdevelopment thinkers and writers have critiqued development discourse for its role in perpetuating inequality. In water, sanitation and hygiene (WASH) literature and interventions, the discourse used perpetuates inequality through classing anything other than private toilets as ‘without sanitation’. This implies that the people who use forms of hygiene and sanitation relying on collective toilets and alternative strategies are somehow unhygienic. Yet residents of Xining (Qinghai Province, China) rely on hygiene assemblages that do not always include private toilets, but nonetheless still work to guard health for families with young children. In this paper, I develop a postdevelopment approach to hygiene and sanitation starting with the place‐based hygiene realities already working to guard health in some way, then working to multiply possibilities for future discursive and material hygiene realities.

Toxoplasma Gondii in Swine in South-Eastern Norway

A total of 407 swine bred in south-eastern Norway have been tested for the presence of Toxoplasma gondii antibodies in serum by use of the dye-test, and diaphragm muscle from all sero-positive and some sero-negative swine has been tested for the presence of mouse-infective cysts.The prevalence of antibodies was as low as 10.1 %. The prevalence increased with the weight of the swine, but apparently with a decline after passing a weight of 140 kg. Only dye-test titres up to 50 were found. The prevalence of dye-test positive swine was higher in small herds (< 300 swine p.a.) than in larger ones (> 300 swine p.a.). The prevalence of herds with dye-test positive swine in the region surrounding the Oslo-fjord was higher in the coastal than in the inland zone. The incidence of infection was the same during the summer-autumn period as during the winter-spring period. Toxoplasma was recovered from the diaphragm muscle of about % of the dyeπtest positive swine. Parasites were isolated from some pigs with a dye-test titre of 4, and from all the pigs with a titre of 50. Toxoplasma was not isolated from dye-test negative swine. The epidemiological and food-hygienic significance of porcine toxoplasmosis in Norway is discussed according to the present results.
