OBJECTIVETo investigate the epidemic status of brucellosis in the occupational population in Yuxi, China, and to develop effective prevention and control strategies.
METHODSSerological test was performed for 2320 employees involved in breeding, slaughtering, meat and dairy product processing, veterinary medicine, and sales in counties and districts where brucellosis was detected from 2008 to 2014 in Yuxi; pathogenic detection was performed for those in the occupational population who were suspected of brucellosis.
RESULTSThe results of serological test showed that the infection rate of brucellosis reached 3.32% , and 15 cases of brucellosis had clinical symptoms. The employees involved in breeding had the highest infection rate (4.89%) (χ2=25.75, P<0.05). From 2008 to 2014, the infection rate of brucellosis was 0.37%~4.93% and tended to increase; 67.85% of the occupational population did not take personal protective measures and had a significantly higher infection rate than those who took personal protective measures (4.45% vs 0.94%; χ2=19.42, P<0.05). Among the 161 patients suspected of brucellosis, 42 cases were diagnosed as current brucellosis confirmed by laboratory pathogenic detection.
CONCLUSIONThe infection rate of brucellosis and the number of newly diagnosed cases tend to increase in the occupational population in Yuxi, and the employees involved in breeding are the major infected population.

OBJECTIVES: The incidence of zoonoses in Korea has increased recently. However, the study of high risk groups for zoonoses has not been conducted to date in Korea. Thus, we did this study to obtain data on brucellosis among slaughterhouse workers in Korea. METHODS: We evaluated the structure of slaughterhouses and the process of slaughtering by reviewing the relevant literature and doing field studies. We visited 73 slaughterhouses and 62 residual products handle houses across the country. In addition, we conducted a questionnaire survey of the work activities, and obtained blood samples in order to determine the seroprevalence and risk factors of brucellosis. The titers of brucellosis antibodies were measured using the standard tube agglutination test (SAT). We diagnosed subjects as seropositive for Brucellosis if the titers were more than 1:160. The data collected was evaluated using SPSS ver. 17.0. RESULTS: We included 1,503 subjects and obtained 1,482 blood samples among them: 849 workers involved in slaughtering, 351 handlers of residual products, 190 inspectors and their assistants, and 92 grading testers and their assistants. The seroprevalence of brucellosis among the slaughterhouse workers was 0.8% (95% CI=0.4-1.5). Broken down, the seroprevalence of brucellosis among the workers involved in slaughtering was 0.7% (95% CI=0.3-1.6), the handlers of residual products was 1.7% (95% CI=0.7-3.9) respectively. Risk factors for contracting brucellosis among slaughterhouse workers were being splashed with cattle blood around the mouth, cattle secretions around the body and not putting on protective apron while at work. CONCLUSIONS: An educational program is needed for high risk groups on zoonoses about the prevention of infection. Thus, effective working guidelines for workers who participate in the slaughter of animals must be developed in order to protect them from zoonoses.

OBJECTIVETo investigate the occurrence and protection of skin/mucosa contamination among obstetrician and gynecologist.
METHODSBy random, stratified, and clustered sampling, 219 obstetrician and gynecologist were selected. 210 valid questionnaires were collected, efficiency is 95.89%. 110 obstetrician and gynecologist come from tertiary hospitals, 100 come from secondary hospitals. A self-administered questionnaire on skin/mucosa contamination was employed to gauge the implementation of protection, types and working links of skin/mucosa contamination.
RESULTSOf the respondents, only 14.76% (31/210) and 5.24% (11/210) adhered to proper hand washing and wearing protective glasses within nearly 1 year in practical work. Of the respondents, 73.81% (155/210) had experienced the skin/mucosa contamination during their vocation, 50.95% (107/210) occurred sharps injuries, 45.71% (96/210) occurred damaged skin contamination, and 43.33% (91/210) occurred mucosa contamination. Sharps injuries mainly occurred when abdominal operation (45.71%, 96/120), damaged skin contamination mainly occurred when gynecological examination (21.43%, 45/210), and mucosa contamination mainly occurred when midwifery (37.14%, 78/210).
CONCLUSIONThe implementation of protective measures is inadequate and incidence of skin/mucosa contamination is higher among obstetrician and gynecologist. Therefore, occupational protection education should focus on different types and working links of skin/mucosa contamination. At the same time, strict supervision and management system should be established.

INTRODUCTIONHelicobacter pylori has been recognised as a major cause of gastroduodenal diseases, including gastric and duodenal ulcers with faeco-oral, oro-oral and gastro-oral transmission occurring. With the close personal contact inherent in patient care, health care workers may be at an increased risk of acquiring H. pylori and subsequent development of associated conditions. The objective of this review was to review the transmission and the occupational risk for health care workers.
METHODSA literature search was performed using Pubmed (January 1990 to May 2001). Relevant key words were used and additional manual searches were made using the reference lists from the selected articles to retrieve other papers relevant to the topic.
RESULTSCurrent knowledge implies various pathways of agent transmission, favouring person-to-person mode of transmission early in life. Faeco-oral, oro-oral and gastro-oral transmissions are proposed and may be of different relevance among various populations. As for health care workers, after elimination of the methodological weak studies, the risk seems to be increased in gastroenterologists, endoscopy staff and intensive care nurses. Results in other groups are conflicting.
CONCLUSIONSH. pylori infection is an occupational risk in some groups of health care workers. Studies are needed to elucidate the risk in other occupational groups.

OBJECTIVETo investigate the cause and related risk factors of an outbreak caused by Brucellosis.
METHODSEpidemiological investigation and laboratory test were carried out among occupationally invloved population including sheep slaughters and sellers in the village.
RESULTS18 people were serology positive among the 129 occupationally involved persons under survey. Seven of them were confirmed cases, 11 were latent infection, to make the overall attack rate as 14%. 90% of the sheep were from high-risk areas of Brucella. Among the occupationally involved persons, 89% of them never wore face masks, 84% never wear overalls and 70% never wear gloves. Factors as:work but wearing no gloves (RR = 7.4, 95%CI:1.1-53.0), with hand wound (RR = 3.4, 95%CI:1.1-11.0) could increase the risk of Brucella infection.
CONCLUSIONThe cause of this outbreak was due to the plentiful influx of unchecked sheep from the northern part of China and the employees in the process of sheep slaughtering or trading were lack of effective prevention programs.

This study was conducted to determine the prevalence of livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) in pigs, farm workers, and the environment in northern Thailand, and to assess LA-MRSA isolate phenotypic characteristics. One hundred and four pig farms were randomly selected from the 21,152 in Chiang Mai and Lamphun provinces in 2012. Nasal and skin swab samples were collected from pigs and farm workers. Environmental swabs (pig stable floor, faucet, and feeder) were also collected. MRSA was identified by conventional bacterial culture technique, with results confirmed by multiplex PCR and multi locus sequence typing (MLST). Herd prevalence of MRSA was 9.61% (10 of 104 farms). Among pigs, workers, and farm environments, prevalence was 0.68% (two of 292 samples), 2.53% (seven of 276 samples), and 1.28% (four of 312 samples), respectively. Thirteen MRSA isolates (seven from workers, four from environmental samples, and two from pigs) were identified as Staphylococcal chromosomal cassette mec IV sequences type 9. Antimicrobial sensitivity tests found 100% of the MRSA isolates resistant to clindamycin, oxytetracycline, and tetracycline, while 100% were susceptible to cloxacillin and vancomycin. All possessed a multidrug-resistant phenotype. This is the first evidence of an LA-MRSA interrelationship among pigs, workers, and the farm environment in Thailand.

Eleven cases of human brucellosis occurred among livestock workers and a veterinarian who lived and worked in a rural area around Jeongeup City, Jeollabuk-Do, Korea from February 2003 to August 2003. Eight of the patients had taken care of Korean native cattle that were infected with bovine brucellosis and had already been slaughtered. Two of the patients had taken care of dairy cattle, and one case was a veterinarian who acquired the disease through an accidental contact with infected cattle while assisting in calf delivery. Eleven cases were identified by serologic work ups and four cases were identified via positive blood cultures. This study shows that the Republic of Korea is no longer free of human brucellosis, Brucella abortus biotype 1. We reviewed the patients' characteristics and serologic data during the oneyear follow up period, and we also discuss on the efficacy and side effects of the rifampin and doxycyline regimen used for the treatment of human brucellosis.
