The antibody titers against Coxiella burnetii (Q fever) among cattle raised in Gwangju area were analyzed from February to October in 2015. The prevalence of antibodies in collected bulk-tank milk from 7 dairy cattle farms was 57.1% and the seroprevalence of 210 dairy cows randomly selected from those farms was 7.1%. By age, the seroprevalence was 3.3% in less than 4 years of age, 9.0% between 4 and 7 years of age, and 28.6% in more than 8 years of age. On the other hand, the seroprevalence of the Hanwoo cattle was 0.4%. The result suggested that the antibodies against Coxiella burnetii increase as the age of the dairy cows increases and therefore, it is necessary to keep monitoring the prevalence of Q fever in Gwangju area.

This Study has been carried out to make a recommendation for the next amendment of the Infectious Disease Prevention Act with a specific focus on the kind of notifyable disease. Korean, Japanese, German, U.S, English and French acts on infectious diseases prevention were reviewed, compared with and analized in regards of numbers and kinds of notifyable infectious diseases and their tendency of amendments. An criteria was designed to assess the level of validity of diseases to be designated in the act. Four items, the fatality (greater than 10% or not), the possibility to make a big epidemic, the availability of efficient vaccination and the usefulness of isolation, are used in the assessment. This index is applied to the diseases in Korean and other countries' Infectious Disease Prevention Acts. Results are as follows: 1. The Korean Infectious Disease Preventon Act has a unique way of classifying the notifyable infectious disease, that is, the first, the second and the third class. But the author cannot find the basis of classification. No other countries reviewed have the similar classification. 2. The ten diseases, cholera, plague, yellow fever, diphtheria, typhoid fever, poliomyelitis, rabies, tetanus, malaria, and meningococcal meningitis are designated as the notifyable diseases not only in Korea but also in Japan, Germany, United States, England and france. 3. Thirty seven diseases including small pox, Lassa fever, anthrax, influenza, German measles, Legionellosis, infection with E. coli O157:H7, Q-fever, brucellosis, Lyme disease are designated as legal disease at least one of the above mentioned countries. 4. The Korea has been coped with the change of the infectious disease occurrence for last fifty years in amendment of the Infectious Disease Prevention Act. 5. Japan has a special infectious surveillance system composed of 3,880 clinics throughout the whole country. 6. Germany has classified infectious diseases in five categories which are based on seriousness of disease. Any confirmed death, cases and suspected cases in class I should be reported within 24 hours. But only confirmed death and cases in class II, but not suspected cases, are reportable in Germarny. 7. Plague, bacillary dysentery, pertussis, mumps, Japanese encephaltis and Korean hemorrhagic fevers are diseases with high credits validity index among Korean legal disease. 8. German measles, anthrax, E. coli O157 : H7 infection, Lassa fever, Q-fever, brucellosis are high in validity index among those which are not designated in Korea but designated in other countries. In conclusion, the Korean Infectious Disease Prevention Act has well been coped with the changes of infectious disease occurrence for last fifty years, but the classification basis and the validity of diseases to be designated as legal diseases is worth reevaluating.

Objectives: General livestock farmers are known as a high riskgroup for zoonoses, but studies of general livestock farmers in regard tozoonoses have been rare in Korea. We surveyed awareness of zoonoses amonggeneral livestock farmers to suggest directions for education. Methods: A questionnaire was developed examining the workbehaviors and risk factors of general livestock farmers. We conducted a questionnairesurvey on awareness on zoonoses among 265 general livestock farmers. Results: The awareness rates for zoonosis itself,brucellosis, and q-fever were 13.0%, 65.0%, and 2.3%, respectively. The awarenessrate of zoonoses and brucellosis tended to increase with sex. Conclusions: Livestock is the principal reservoir ofzoonoses. Therefore, effective working guidelines for preventing zoonoses amonggeneral livestock farmers must be developed and an educational program onzoonoses is needed for general livestock farmers. Furthermore, publicityactivities on the prevention of zoonoses are needed for high-risk groups.

Q fever is a zoonotic disease caused by the obligate intracellular bacterium Coxiella (C.) burnetii and affects wild and domestic animals worldwide. The aim of this study was to evaluate the seroprevalence of C. burnetii in native Korean goat (Capra hircus coreanae) in Gyeongbuk province, Korea, using ELISA. A total of 256 goat blood samples from 56 farms in Gyeongbuk province were collected between May 2012 and March 2013. Among them, 22 (8.6%) samples from 10 (17.9%) farms were seropositive for C. burnetii by ELISA. According to regional analysis, the seroprevalences among goat farms in eastern, western, southern, and northern areas of Gyeongbuk province were 0%, 18.2%, 36.8%, and 6.3%, respectively, showing the highest seroprevalence in the southern region. Among 22 counties in Gyeongbuk province, 10 (45.5%) counties had one or more farms positive to C. burnetii antibody. Accordingly, the seroprevalence of C. burnetii in high-risk humans and animals are constantly demanded by regional investigation.

Background: Acute myeloid leukemia (AML) is a clonal hematopoietic disorder resulting from genetic alterations in normal hematopoietic stem cells. The aim of this study was to evaluate prognostic factors and survival of AML patients in the Northeast of Iran. Materials and Methods: This retrospective study covered 96 patients with AML referred to Emam Reza Hospital, Mashhad city, Iran, from 2009 to 2015. Age, sex, blood group, type of AML, fever, consumption of amphotericin B, cytogenetic forms and survival were analyzed. Also, WBC, hemoglobin and platelet levels were checked. Mean follow-up was 30.5 months (60.4% mortality). Survival was plotted by GraphPad Prism 5 with Log-rank test. Results: The mean age for all AML patients at diagnosis was 40.4 years (range, 17-77 years). Some 42.7% patients were aged <35 years and 40.6% were male. In all patients, 76% had fever and 50% consumed amphotericin. T(15;17)(q22;q21) had the most prevalence (37.7%) compared to other forms. Out of 92 patients, O+(30.4%) was the most common blood group and AML-M5 (28.3%) the most common subtype. There was a significant difference in survival based on WBC and consumption of amphotericin B (P<0.05). Conclusions: WBC level, fever and consumption of amphotericin B proved to be factors for survival of AML patients. The mean age for patients in Iran is lower than other areas in the World and also survival in this study was higher than in other studies.

In this study, a simple loop-mediated isothermal amplification (LAMP) combined with visual detection method (vLAMP) assay was developed for the rapid and specific detection of African swine fever virus (ASFV), overcoming the shortcomings of previously described LAMP assays that require additional detection steps or pose a cross-contamination risk. The assay results can be directly detected by the naked eye using hydroxynaphthol blue after incubation for 40 min at 62℃. The assay specifically amplified ASFV DNA and no other viral nucleic acids. The limit of detection of the assay was <50 DNA copies/reaction, which was ten times more sensitive than conventional polymerase chain reaction (cPCR) and comparable to real-time PCR (qPCR). For clinical evaluation, the ASFV detection rate of vLAMP was higher than cPCR and comparable to OIE-recommended qPCR, showing 100% concordance, with a κ value (95% confidence interval) of 1 (1.00~1.00). Considering the advantages of high sensitivity and specificity, no possibility for cross-contamination, and being able to be used as low-cost equipment, the developed vLAMP assay will be a valuable tool for detecting ASFV from clinical samples, even in resource-limited laboratories.

Shigella sonnei is a causal agent of fever, nausea, stomach cramps, vomiting, and diarrheal disease. The present study describes a quantitative polymerase chain reaction (qPCR) assay for the specific detection of S. sonnei using a primer pair based on the methylase gene for the amplification of a 325 bp DNA fragment. The qPCR primer set for the accurate diagnosis of Shigella sonnei was developed from publically available genome sequences. This quantitative PCR-based method will potentially simplify and facilitate the diagnosis of this pathogen and guide disease management.
