The hollow stalk, caused by Erwinia carotovors var. carotovora, is probaly the most devastating disease to burley tobacco in Korea. There are two modes of infection to tobacco plants: the primary infection along the plant stem from soil and the secondary one from the topped end of plants. The secondary infection rate could be reduced to almost zero by applying an antibiotic, streptomycin sulfate(400 ppm solution), right after topping.

Leishmania tropica and L. major are etiologic agents of human cutaneous leishmaniasis. Delayed type hypersensitivity (DTH) is an immunologic response that has been frequently used as a correlate for protection against or sensitization to leishmania antigen. In BALB/c mice, L. tropica infection results in non-ulcerating disease, whereas L. major infection results in destructive lesions. In order to clarify the immunologic mechanisms of these 2 different outcomes, we compared the ability of these 2 leishmania species in induction of DTH response in this murine model. BALB/c mice were infected with L. major or L. tropica, and disease evolution and DTH responses were determined. The results show that the primary L. major infection can exacerbate the secondary L. major infection and is associated with DTH response. Higher doses of the primary L. major infection result in more disease exacerbation of the secondary L. major infection as well as higher DTH response. L. tropica infection induces lower DTH responses than L. major. We have previously reported that the primary L. tropica infection induces partial protection against the secondary L. major infection in BALB/c mice. Induction of lower DTH response by L. tropica suggests that the protection induced against L. major by prior L. tropica infection may be due to suppression of DTH response.

With the development of medical technologies and the growth of household incomes, most of the people have become to be interested in health as it leads to significant early detection and cure of diseases. However the pattern of disease becomes diverse and it makes the imaging diagnosis department crowded with many patients. Therefore the opportunistic infection could be serious there. The hospital becomes the place which provides high risks of infection danger but it is true that the opportunistic infection of the hospital employees is not still recognized well. The imaging diagnosis department has developed a lot but it becomes the medium of secondary infection of patients and employees. So this study analyzesthe status of bacteria infection of the examination table, the handle of diagnostic equipment and the hands of radiation staffs in imaging diagnosis department of the general hospitals and individual ones. And the result shows that some bacteria were found even though it's little. We are trying to make the hospitals to be free of secondary infection securing safety measure to prevent the secondaryinfection from occurring to patients and hospital employees.

Thermal burn occurred in the anesthetized dog as a result of using hot pack to treat hypothermia. After hospital discharge, thermal burn leaded to secondary infection due to dog bites of the other dog in the house. After secondary infection, the treatment was performed with medication and bandaging. Because of the pain and infection from the wound, carprofen (2 mg/kg bid) and amoxicillin (20 mg/kg bid) were administrated orally for 40 days. And for 35 days, wet-to-dry gauze dressing was used to absorb purulent exudate. During this period, the burn eschar was removed completely from the burn site. After 35 days, the hydrophilic polyurethane foam ($Medifoam^{(R)}$, Ildong Pharm, Co., Korea) was admitted to the burn site for 30 days. $Medifoam^{(R)}$ made healing rate of the wound faster because the inner layer did not adhered to the wound, and newly formed tissue was protected. The second layer, hydrophilic absorptive layer absorbed excessive fluid and kept the wound surface moist. After 65 days after thermal burn, the wound was healed completely.

The complications of deep neck infection have become much less common in the antibiotic era. The vascular complications of deep neck infection can have devasting consequences. Most commonly, the internal carotid artery is involved, although the common carotid and external carotid artery can also be affected.0 the cases of patients with a protracted course, recurrent bleeding, cranial neuropathies, or trismus, the presence of vascular complications must be considered. Appropriate imaging should be carried out to allow the localization of the infection and ascertain the status of the vessels in the neck The vascular structures can be imaged with duplex doppler or color doppler flow ultrasound to see the flow between the mass and vessels. Also angiography plays a key role in the diagnosis and management of vascular complication of deep neck infection. Prompt diagnosis and treatment of these patients is necessary to prevent significant hemmorrhagic complications. We experienced a case of pseudoaneurysm of the common carotid artery secondary to deep neck infection treated successfully with surgical excision in 45-year-old-male.

Objectives : There were few reports on Erysipelas, from Secondary Skin Infection after Herpes Zoster. We treated Erysipelas, from Secondary Skin Infection after Herpes Zoster with Oriental medical approach, and got a significant results. So We are reporting this case. Methods : Herb medication, acupuncture treatment were applied for treating patient`s chief symptoms (erythema, heat sensation, swelling, pain, itching and general weakness) Results : The patient was 5-year-old boy who had the symptoms caused by Erysipelas, which was caused by secondary skin infection after herpes zoster. He had erythema, heat sensation, swelling, pain, itching and general weakness. We judged him as Soyangin(少陽人), and prescribed Hyeongbangsaback-san. After he took Hyeongbangsaback-san, the symptom and general condition were improved. In this report, we want to explain the healing process and the result of the treatment of Erysipelas. Conclusions : More study about oriental treatment on Erysipelas, from Secondary Skin Infection after Herpes Zoster is needed.

Cytauxzoonosis is caused by Cytauxzoon felis (C. felis) in wild and domestic cats. However, cytauxzoonosis is uncommon in Asia. Additionally, clinical reports of C. felis infection along with associated complications are rare. A seven-year-old neutered male Maine Coon cat was presented with acute dyspnea and lethargy despite the absence of a history of overseas travel. Mild regenerative anemia and autoagglutination were detected in hematological investigations. The parasitic and viral PCR assays revealed infection with C. felis and feline immunodeficiency virus (FIV). Thoracic radiographs showed pleural effusion with secondary bacterial infection. Ultimately, a diagnosis of infection-induced secondary immune-mediated hemolytic anemia (IMHA) and pyothorax was established. The cat was treated with a combination of atovaquone, prednisolone, and cyclosporine over 6 months and the final treatment was completed 8 months after initiation of therapy. This is the first report of its kind demonstrating successful management of feline IMHA and fatal pyothorax induced by FIV and C. felis in South Korea.

In this study, we estimated the number of secondary COVID-19 infections caused by students with potential transmission potential home. When the existing Monte Carlo method was applied to Korean data, the average number of household members of the second COVID-19 infected was predicted. The summary of this study is as follows. First, in general, the number of secondary infections by students returning home from school is greatly influenced by the virus infection rate of each student group they contact while returning home from school. Korea-based empirical research on this is needed. Second, the number of secondary infections by Korean students was relatively lower than that of previous studies. This can be interpreted as being due to the domestic furniture structure. Third, unlike previous studies that assumed the distribution of secondary infected individuals as normal distribution, assuming a negative binomial distribution, the number of secondary infected individuals was sensitively changed according to the estimated parameters. Interpretation of this result shows that the number of secondary infections may vary depending on the time of decision making, the target region, and the target student group. Finally, according to the results of this analysis, a proposal was made to support education policy decisions.
