Bovine hypodermosis is a myiasis caused by Hypoderma bovis and Hypoderma lineatum (Diptera, Oestridae) larvae, which has a severe economic impact on the livestock industry. Though myiasis is widespread throughout Italy, no nationwide eradication program has ever been planned, unlike in other European Countries. With a view to setting up a national control program, a pilot study was carried out in Southern Italy on 9939 cattle bred in an area with a, high prevalence of cattle hypodermosis, using moxidectin 0.5% pour-on (Cydectin((R)), Fort Dodge) and 1% injectable (Cydectin((R)), Fort Dodge) formulations. At the recommended dosage, moxidectin displayed efficacy levels of 99.9% in the pour-on and 100% in the injectable formulation, whereas the microdose (1 mg per head regardless of body weight) was less effective (65.7%). This trial contributed to a significant reduction in infestation rates in the study area and represented the first step through which a national program for eradicating warble fly infestation in Italy.

In Sweden, competitive exclusion (CE) treatment has been used since 1981 as a part of the national control programme for Salmonella. According to the programme all broiler flocks are tested for Salmonella before slaughter thus providing an evaluation of CE treatment. The CE culture used is mainly for the two consecutive flocks raised in a unit after a Salmonella-infected flock has been identified. During the period 1981-1990 CE culture has been given to 179 flocks, involving 3.82 million chickens. Only one of the treated flocks was found to be Salmonella-positive. A special study during a period when Salmonella was spread by contaminated feed demonstrated that CE treatment was effective in controlling Salmonella under field conditions. A likely contributory factor is that the hatcheries in Sweden can be claimed to be Salmonella-free. In addition, the control programme and related action, have led to a very low incidence of Salmonella in broiler chickens. A nationwide study carried out in 1990 demonstrated that less than 1% of broiler chickens was contaminated with Salmonella after slaughter.

BACKGROUND. Antibiotics account for 30% of hospital pharmacy expenses. More than 50% of the prescriptions are considered inappropriate;hence, programs devoted to optimizing the prescription of antibiotics should be developed. We present the results of a non-compulsory program for the assessment and control of antibiotic treatment in the University Hospital 12 de Octubre in Madrid. METHODS. The program was applied in the hospitalization units of six medical and surgical departments. Treatments in all patients were checked daily and recommendations were made in writing, according to previously established criteria. The program was used for 12 months and the results were compared with those of the previous 12 months. RESULTS. 1,280 treatments were reviewed and 524 recommendations were made (80% of them were accepted). There was a 13.82% reduction in the number of defined daily doses of antibiotics/100 inpatient-days. Antibiotic expenditure decreased by 65,352 euros (5,446 euros/month), implying a reduction of 1.21 euros/hospitalization-bed/day. There were no statistically significant differences in length of hospital stay or mortality between the two periods. A reduction in the incidence of Clostridium difficile diarrhea (p < 0.0001) and Candida spp. isolations (p < 0.05) was observed. CONCLUSIONS. Following application of a non-compulsory control program, antibiotic prescription improved and expenditure decreased, with no change in length of hospital stay or mortality. There was a reduction in the incidence of some nosocomial infections. Acceptation of the program by the physicians of the departments implicated was favorable.

in spite of the great achievements gained in the national schistosomiasis control program during the last 5 decades, serious challenges for the control program exist due to the impact of biological factors, environmental facts and limitation of scientific technology, as well as shortages of socio-economic development in the endemic areas. This paper reviewed the experiences of the national control program, then the author considered it essential to put forward a newly sustainable strategy with an emphasis on the areas with high endemicity of schistosomiasis, on poverty-stricken areas, especially in the Western part of the People's Republic of China. when taking into account both the opportunities and challenges of the future. It is expected that the schistosomiasis control program with a sustainable strategy would promote local economic development in the People's Republic of China.

With the development and popularization of computer network, and speed up the pace of government and enterprise informatization, network architecture and existing enterprises more complex. The complex network structure exposed a lot of security problems, personal and corporate demand for network security grows with hitherto unknown speed. How to let the rapid advance of network security to satisfy business, become a hot topic. Network security is the supporting system of daily office and business applications for the modern enterprises. In the enterprise network, only like a personal computer network security protection just install personal version of virus protection program and software firewall is not enough, and should also deploy hardware firewall, network virus protection program and other such as intrusion detection system, network isolation equipment etc.. At the same time, it is necessary to deploy enterprise network disaster tolerance system, because it is all safety protection measures in the last line of defense. This paper mainly describe, safety control program of firewall in enterprise network security is how to design. I hope that this paper can help everyone to design network security protection systems.
