We investigated the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in China and determined the susceptibility of S. aureus to 26 antimicrobial agents, including ceftobiprole, linezolid, and tigecycline. A total of 798 isolates were collected and tested by agar dilution. The mean prevalence of MRSA was 50.4%, the highest in Shanghai (80.3%), followed by those in Beijing (55.5%) and Shenyang (50.0%). Only 4.2% to 12.6% of MRSA were susceptible to erythromycin, fluoroquinolones, gentamicin, and tetracycline. All isolates were susceptible to teicoplanin, vancomycin, linezolid, tigecycline, and ceftobiprole.

Thirty-one case-patients with MRSA with spa types related to MRSA CC398 were detected from October 29, 2003, through February 16, 2007. Of these, 6 were excluded from the study because they had secondary cases (3 family clusters). Of the remaining eligible casepatients,

we were unable to interview 4 because of a death (n = 1) and refusal to participate (n = 3). The questionnaire was therefore administered to 21 of 25 primary case-patients. Median age of the case-patients was 29 years (age range 8 months to 80 years), and 13 (62%) were female.

Three case-patients reported having Dutch relatives, and 2 case-patients had a connection to the People’s Republic of China; 1 case-patient was an adopted child from China and another casepatient had adopted a child from China.

Ten case-patients (48%) reported having had an infection, of which all were skin and soft tissue infections. Moreover, sinusitis developed in 1 case-patient, and a severe invasive infection with multiorgan failure after knee surgery developed in another case-patient.

The majority of PFGE type F isolates (31/35) carried the SCCmec II gene; these isolates belonged to ST5. PFGE type G isolates carried SCCmec I or II gene and belonged to ST45. Two of the three PFGE type I isolates had ST398 (allele no. 3-35-19-2-20-26-39) and carried the SCCmec IVa gene. These MRSA strains were resistant to fusidic acid alone and may represent those of community acquisition. However, these strains were few in number and were present only in isolates from one hospital.

Between January 2005 and January 2006, 25 (12.8%) of 195 Staphylococcus aureus isolates were positive for Panton–Valentine leukocidin (PVL) genes in a teaching hospital in Wenzhou, China. Nineteen (11.9%) of 160 hospital-acquired isolates, and six (17.1%) of 35 community-acquired isolates, harboured lukS/F-PV. Six sequence types (ST88, ST239, ST398, ST25, ST30 and ST59) were found among 18 PVL-positive methicillin-resistant isolates with SCCmec types I, III, IIIA or IV. Only ST88 was found among seven PVL-positive methicillin-susceptible S. aureus isolates. The PVL-positive isolates were associated with lung infection, bloodstream infection and soft-tissue pyogenic infection. Overall, there was a high prevalence of PVL genes in genetically diverse S. aureus isolates.

In recent years, especially since the SARS outbreak in 2003, healthcare reform, primarily in the rural regions of China, has received unprecedented attention from the central government. While a rural health insurance system, the Cooperative Medical Scheme (CMS), had existed in China prior to its economic reforms, the CMS floundered during the early 1980s primarily because of the collapse of the rural collective economy. As a result, some 90% of the rural population was left without any type of health insurance coverage. In 2003, the central government decided to subsidize the operation of the CMS for the poorer provinces. This was the first time that Beijing had allocated funds from the central government budget to support a rural health insurance plan. In addition to subsidizing the CMS, Beijing also created a medical assistance fund. Under this system, those suffering from debilitating diseases could apply for cash subsidies. The government has also devoted large amounts of funding to construct disease control institutions and purchase necessary healthcare equipment.

Locating large chicken farms near cities might make economic sense, but the close concentration of the birds to densely populated areas can help foster and spread disease, Nierenberg says. In Laos, 42 of the 45 outbreaks of avian flu in the spring of 2004 occurred on factory farms, and 38 were in the capital, Vientiane (the few small farms in the city where outbreaks occurred were located close to commercial operations). In Nigeria, the first cases of avian flu were found in an industrial broiler operation; it spread from that 46,000-bird farm to 30 other factory farms, then quickly to neighboring backyard flocks, forcing already-poor farmers to kill their chickens.

Due mainly to the spread of avian flu and the culling of birds, global poultry output rose only slightly in 2006 to approximately 83 million tons, roughly a 1-percent decrease from the preceding year. Pig meat production, however, grew by 3 percent to 108 million tons, an increase likely due to shifting consumption in Asia from chicken to pork due to concerns about avian flu.

Avian flu has existed among backyard flocks for centuries, but has never been found to evolve there into highly pathogenic forms such as the deadly H5N1 virus. In CAFOs, in contrast, where animals are concentrated by the thousands, diseases erupt and spread quickly. Trade in poultry from these operations is a culprit in spreading the disease to smallholder farmers.

We report 2 patients infected with Panton-Valentine leukocidin (PVL)–positive MRSA t034. Each patient had a medical history typical of that reported for community-acquired MRSA of other lineages, which in most cases are PVL positive (8).

The first patient, a previously healthy 36-year-old male physiotherapist, sought medical care in March 2006 for a small abscess in his axilla. Culture of the abscess grew MRSA. Presence of mecA gene was confirmed by PCR (9). During the next 2 months, furunculous developed twice, caused by the same strain. His youngest child, adopted from China, had been found to be MRSA positive (throat, perineum, and a small wound) a month earlier during routine screening for adopted children. During subsequent screening of the family, the older sister, adopted from South Korea, was also found positive (throat). Both parents were negative for MRSA at that time, which suggests that the father was newly infected when his abscess developed and that he had not acquired the strain abroad. Also, spa typing indicated that the children carried different strains from that of the father and from each other (t286, t1434) (10). Subsequent screening of family members for MRSA on several occasions found only the father to be repeatedly positive.

The second patient, a 43-year-old male clerk, also previously healthy, sought medical attention during the summer of 2007 for a MRSA-infected elbow wound. Follow-up examination determined that he carried MRSA also in the perineum and in a chronic external otitis eczema. He was later hospitalized for a larger abscess that required surgical drainage. His family members reported no symptoms and were thus not screened for MRSA.
