Following the Anthrax bioterrorism attacks in the US in 2001, the Korean government established comprehensive countermeasures against bioterrorism. These measures included the government assuming management of all infectious agents that cause diseases, including smallpox, anthrax, plaque, botulism, and the causative agents of viral hemorrhagic fevers (ebola fever, marburg fever, and lassa fever) for national security. In addition, the Korean government is reinforcing the ability to prepare and respond to bioterrorism. Some of the measures being implemented include revising the laws and guidelines that apply to the use of infectious agents, the construction and operation of dual surveillance systems for bioterrorism, stockpiling and managing products necessary to respond to an emergency (smallpox vaccine, antibiotics, etc.) and vigorously training emergency room staff and heath workers to ensure they can respond appropriately. In addition, the government's measures include improved public relations, building and maintaining international cooperation, and developing new vaccines and drugs for treatments of infectious agents used to create bioweapons.

Options available for utilization of animal wastes include sources of plant nutrients, feed ingredients for farm animals, substrate for methane generation, and substrate for microbial and insect protein synthesis. The wastes have the most economic value for use as animal feed. Performance of animals fed diets containing animal wastes is similar to that of animals fed conventional diets. Processing of animal wastes to be used as animal feed is necessary for destruction of pathogens, improvement of handling and storage characteristics, and maintenance or enhancement of palatability. Feeding of animal waste has not adversely affected the quality and taste of animal products. In the USA copper toxicity has been reported in sheep fed high-copper poultry litter, but this is not a serious problem with cattle. Potential pathogenic microorganisms in animal wastes are destroyed by processing such as heat treatment, ensiling and deep stacking. Incidents of botulism, caused by Clostridium botulinum, have been reported in cattle in some countries, and this problem was caused by the presence of poultry carcasses in litter. This problem has not occurred in the USA. With appropriate withdrawal, heavy metal, pesticide or medicinal drug accumulation in edible tissues of animals fed animal wastes is not a problem. Feeding of animal wastes is regulated by individual states in the USA. The practice is regulated in Canada, also. With good management, animal wastes can be used safely as animal feed.

Two separate cranial nerve variants of Guillain-Barre syndrome(GBS) have been reported. One is Miller-Fisher syndrome, the other is polyneuritis cranialis. Involvement of the extraocular muscles in variants of GBS is well recognized, but complete external and internal opthalmoplegia is rare. Optic neuritis remains the only consistent, albeit very uncommon, evidence of inflammation of central nervous system myelin in GBS. This propose that GBS is part of a spectrum of central and peripheral inflammation. This case is an unusual clinical variant who had ptosis, opthalmoplegia, areflexia, ataxia, optic neurritis, marked oropharyngeal, and neck and shoulder weakness. This combined regional from is able to misdiagnose initially as botulism or diphtheria and less so, myasthenia. So if we were consider variant from of GBS, it is possible for make a correct diagnosis more easily and treatment without delay.

Soil samples and the intestinal contents of arthropods, mollusca, pisces, aves, and mammals were examined for the presence of Clostridium botulinum. Demonstration of Clostridium botulimun was accomplished by identifying its toxin in liquid cultures inoculated with soil or material from the alimentary tract of tested animals with toxin neutralization tests in addition to morphological, cultural and biochemical tests. Incidences of Clostridium botulinum in tested samples were 5.0% in soil, 6.7% in mammal and 8.7% in fish, respectively. All of the positive cultures were identified as Clostridium botulinum type E and any other type was not demonstrated throughout the survey. Canned foods and solid ham/sausage mixture formulated as can with distilled water were inoculated with Clostridium botulinum type E and checked for toxin production by using the mouse bioassay. Clostridium botulinum type E toxin was produced as a large quantity in canned foods of fish, shell, meat and ham and, however, no significant toxin was detected in sausages and fruit samples.

Si-Raw is a raw cured meat (raw, cured meat fermented with steamed rice) produced by the aboriginal people of Taiwan. In order to prevent food poisoning or intoxication from botulism, new methods of monitoring the production base on hurdle technology were investigated. New methods investigated incorporated citric acid, sodium hypophosphite, Monascus anka mash, plum paste or lactic acid bacteria inoculum added separately to meat with steamed rice and salt to lower the Aw (water activity) and pH values of the products to control the microbial growth. Results showed that anaerobic bacterial counts, lactic acid bacterial counts and aerobic bacterial counts for the products of all treatments were less than $10^6$, $10^5$ and $10^2cfu/g$, respectively. Sodium chloride content of all products was above 5.46%, water activity was below 0.939 and pH value was below 4.27. IMP was lower and ATP and hypoxanthine were higher. ATP concentrations were higher in the samples which contained the anka mash. Result of sensory panel test indicated that most people preferred the products with added sodium hypophosphite. Except for the fact that the content of tryptamine in the sample with Monascus anka mash was higher, the amine concentrations for all treatments were lower than those of other fermented meat products. The amino acid nitrogen content was higher in the product made from raw meat treated with citric acid, but lower in the other products. Neither Clostridium botulinum nor Trichinella spiralis were detected in any of the treatments. The result may indicate that hurdle technology is effective for hygiene and safe producing Si-Raw.

Production of high-quality horses is important to make the horse industry grow. Grazing during the growing period can be an important factor affecting the production of high-quality horses. The objective of this study was to determine the effects of grazing on growing horses by analyzing their blood components and intestinal microbiota. Twelve growing horses for evaluating blood components and ten growing horses for evaluating intestinal microbiota were raised for about seven months and separated by two treatments: grazing vs. stable. Complete blood count, blood chemistry, and creatine kinase levels were analyzed as blood components and a 16s rRNA gene sequence analysis was performed to analyze intestinal microbiota. Calcium ions tended to be lower in the group with grazing treatment. Alkaline phosphatase and creatine kinase tended to be higher in the group with grazing treatment. These results indicate that grazing can provide horses with more exercise than staying in stables. At the phylum level, Firmicutes/Bacteroidetes ratios in grazing and stable groups were 4.2 and 6.5, respectively. Because various studies have reported that a. high Firmicutes/Bacteroidetes ratio indicates obesity, the method of raising horses might affect their physical ability. At the species level, rates of Clostridium butyricum in grazing and stable groups were 3.2% and 13.1%, respectively. Some strains of C. butyricum can cause several diseases such as botulism. These results indicate that grazing can positively affect growing horses in terms of blood components and intestinal microbiota. Moreover, grazing can be helpful to make growing horses healthy through proper exercise.
