为了进一步提高胚蛋的利用率和胚蛋表面无菌率,防止胚胎受大肠肝菌和霉菌等病源微生物感染,选择不同的消毒液、不同的消毒方式、不同的消毒时间在种蛋入孵前进行消毒实验,以期找到更适合生产实际的消毒液和消毒方法。结果表明:仅单独使用喷雾的方法进行种蛋消毒并没有达到很好的除菌效果,与甲醛熏蒸30min及消毒液喷雾+甲醛熏蒸试验组的消毒效果相比差异显著(P<0.05),明显低于后两者的消毒效果。各试验组之间的利用率差异不显著(P>0.05),所以在利用率相当的情况下,对胚蛋除菌效果好的消毒液喷雾+甲醛熏蒸40min的除菌效果最好,然后依次是消毒液喷雾+甲醛熏蒸30min的除菌效果、甲醛熏蒸30min的除菌效果、消毒液喷雾+甲醛熏蒸20min的除菌效果、最后是百毒杀喷雾的消毒效果。 相似文献

The objective of this study was to develop and test a rapid (< 2 h) sanitation protocol designed for porcine reproductive and respiratory syndrome virus (PRRSV) positive commercial transport vehicles involving cold water washing and disinfection via fumigation using scale models of weaned pig trailers. The study consisted of 2 phases. Following experimental contamination of model trailers with PRRSV MN 30-100 (5 x 10(5)TCID50), phase 1 evaluated the presence or absence of PRRSV RNA by polymerase chain reaction (PCR) on swabs collected from the trailer interiors 0, 60, and 90 min after treatment. Phase 2 consisted of evaluating the infectivity of trailers 90 min posttreatment by monitoring changes in the PRRSV-status of naive sentinel pigs housed for 2 h. Treatments included washing only (treatment 1), washing plus formaldehyde fumigation (treatment 2), washing plus fumigation with glutaraldehyde-quaternary ammonium chloride (treatment 3), and washing plus overnight drying (treatment 4). Porcine reproductive and respiratory syndrome virus RNA was detected in all trailers (20 out of 20 replicates) at 60 and 90 min following the application of treatments 1 and 2. These trailers also contained infectious PRRSV, as determined by the infection of naive pigs housed in treated trailers and the testing of organic debris collected from the interior of trailers by swine bioassay. At 90 min posttreatment, all trailers treated with glutaraldehyde-quaternary ammonium chloride were PCR-negative, non-infectious to sentinel pigs, and swine bioassay negative. Similar results were observed in trailers allowed to dry for 8 h. Under the conditions of this study, it appears certain disinfectants may possess different levels of efficacy against PRRSV and PRRSV-positive models may be effectively sanitized in the absence of overnight drying. 相似文献

Dissection is a very useful method of learning veterinary anatomy. However, formaldehyde, which is widely used to preserve cadavers, is an irritant, and it has recently been classified as a carcinogen. In 1997, the Instituto Nacional de Seguridad e Higiene en el Trabajo [National Institute of Workplace Security and Hygiene] found that the levels of formaldehyde in our dissection room were above the threshold limit values. Unfortunately, no optimal substitute for formaldehyde is currently available. Therefore, we designed a new ventilation system that combines slow propulsion of fresh air from above the dissection table and rapid aspiration of polluted air from the perimeter. Formaldehyde measurements performed in 2004, after the introduction of this new system into our dissection laboratory, showed a dramatic reduction (about tenfold, or 0.03 ppm). A suitable propelling/aspirating air system successfully reduces the concentration of formaldehyde in the dissection room, significantly improving safety conditions for students, instructors, and technical staff during gross anatomy learning. 相似文献

Commercial hatcheries typically infuse hydrogen peroxide or formaldehyde gas into hatching cabinets to reduce airborne pathogens that may lead to disease transmission during the hatch. A nonchemical option, an electrostatic space charge system (ESCS), was customized for full-sized commercial hatching cabinets and was tested extensively in broiler hatcheries. The ESCS cleans air by transferring a strong negative electrostatic charge to dust and microorganisms that are aerosolized during the hatch and collecting the charged particles on grounded plates or surfaces. In studies with three poultry companies, the ESCS resulted in significant (P < 0.0001) reductions of airborne dust of 77%-79%, in Enterobacteriaceae and fungus levels not significantly different (P > or = 0.05) from those with formaldehyde, and in 93%-96% lower Enterobacteriaceae than with no treatment or with hydrogen peroxide treatment (P < 0.01). The ESCS significantly (P < 0.05) reduced airborne Salmonella by 33%-83% compared with no treatment or hydrogen peroxide treatment. Results of this study suggest that the ESCS is a viable alternative to chemical treatment for reducing airborne pathogens in full-sized commercial hatchers, and it also provides dust control and containment, which should be helpful in reducing cross contamination and loading of ventilation ducts within different areas of the hatchery. 相似文献

为了解笼养肉鸡舍整个养殖周期空气中细菌群落组成及病原菌菌属特征,采用FA-3型气溶胶粒度分布采样器,对山东省潍坊市昌邑(X)和安丘(A)2个养殖场空舍期消毒前,消毒后,鸡日龄在7、14、21、28、35 d时舍内空气中细菌进行了采集,应用Illumina HiSeq高通量测序技术测定细菌16S rDNA的V3-V4区序列,分析养殖周期不同时期样本的细菌群落组成。结果表明,所有样本在97%相似度水平下共产生1494个有效操作分类单元(operational taxonomic units,OUT)OUT,涵盖了34门、75纲、102目、147科、220属、75种的细菌;笼养肉鸡舍空舍期消毒和带鸡消毒有一定作用效果,合理通风与笼养肉鸡舍舍内细菌种类的减少有密切关系。通过对空气样本菌群中丰度较高的病原菌属统计,以期为笼养肉鸡场的消毒、用药和笼养肉鸡场生物安全体系的制定提供理论依据。 相似文献

The efficacy of chlorine dioxide (ClO2) as an alternative sanitizing agent for hatching eggs was investigated because of the health concerns about formaldehyde fumigation. Hatchability of chicken eggs was reduced when the eggs were dipped in the ClO2 solutions for more than 5 minutes or in concentrations greater than 100 ppm Cl. However, treating hatching eggs with a ClO2 foam or fumigating with formaldehyde had no adverse effect on hatchability compared with untreated control eggs. Sanitizing soiled duck eggs with ClO2 foam improved hatchability by more than 10% and hatch by more than 6% compared with untreated eggs (P less than 0.05). A novel method for assessing bactericidal potential of egg-sanitizing agents was developed. Using this technique, both chlorine dioxide foam and formaldehyde fumigation reduced the number of egg-contaminant bacteria inoculated on sterile chicken eggs compared with the number of bacteria on untreated eggs (P less than 0.05). These findings suggest that sanitizing hatching eggs with ClO2 foam may be a viable alternative to fumigating with formaldehyde. 相似文献
