摘要:
Balantidium coli is a zoonotic protozoan parasite, and pork is considered the major source of Balantidium infection in humans. Transmission is direct and commonly occurs through the ingestion of water and food, especially vegetables, contaminated with infectious cysts. Ingestion of meat contaminated, with faecal material during the evisceration process, can represent a potential risk of B. coli transmission. In order to determine the rate of B. coli infection in pigs regularly slaughtered at abattoirs in the province of Messina (Sicily, Italy), faecal samples of 242 pigs (122 commercial hybrid and 120 Nero Siciliano pigs) were collected and evaluated by standard methods for the presence of trophozoites and/or cysts. A total of 105 of the commercial hybrid (86.06%), but only 44 of the Nero Siciliano (36.66%) pigs, were identified as positive for B. coli infection. The results obtained, may be linked to the type of farming employed.
摘要:
本研究在意大利東南部的普利亞地區(qū),對(duì)Nero di Troia葡萄園進(jìn)行連續(xù)兩年(2006—2007和2007—2008)的合成及有機(jī)材料的土壤覆蓋實(shí)驗(yàn),研究其對(duì)土壤條件、葡萄長(zhǎng)勢(shì)、生理特性、產(chǎn)量及成分組成的影響。在有機(jī)葡萄園行間進(jìn)行兩種合成材料(聚丙烯土工布和黑色聚乙烯土工布)和一種有機(jī)覆蓋物(3cm和6cm厚的橄欖果渣)的土壤覆蓋,其中以行間除草作為對(duì)照。
