One hundred and twenty methicillin-resistant Staphylococcus aureus (MRSA) isolated from cancer and non-cancer patients in Saudi Arabia were investigated for antibiotic resistance, virulence determinants and genotypes. The majority of MRSA isolates from cancer (n?=?44, 73.3 %) and non-cancer patients (n?=?34, 56.7 %) were multi-resistant to more than four classes of antibiotics. Virulence gene profiling showed that all strains were commonly positive for adhesin genes, except ebps and bbp genes, which were not detected in any isolate. Although the presence of adhesin genes varied slightly among MRSA isolates from cancer and non-cancer patients, these variations were not found to be statistically significant. In contrast, the presence of the toxin genes seb, sec, seg and sei was significantly elevated in MRSA strains isolated from cancer patients. Multilocus sequence typing (MLST) detected six and nine sequence types (STs) among isolates from cancer and non-cancer patients, respectively. Using spa typing, 12 and 25 types were detected, including four new types. The ability of different MRSA clones to become multi-resistant and their ability to acquire different virulence factors may contribute to their success as pathogens in individual groups of patients. 相似文献

The medicinal plant, Syzygium leucoxylon or commonly known as Obah found in North Borneo was considered as traditional medicine by local committee. Two new phenolics, leucoxenols A (1) and B (2) were isolated and identified as major secondary metabolites from the leaves of S. leucoxylon. Their chemical structures were elucidated based on spectroscopic data such as NMR and HRESIMS. Furthermore, these compounds were active against selected strains of fungi. 相似文献

Hidradenomas are tumours that arise from the adnexal structures, both eccrine and apocrine and are histologically benign. The tumours that arise from eccrine differentiation are known as poroid hidradenomas and when they arise from the apocrine glands they are called nodular hidradenomas. In our centre a 13‐year‐old boy presented with a slow‐growing, painless erythematous fungating nodule on the left upper arm over a period of 18 months at the site of the BCG vaccination. The nodule was surgically excised and sent for histopathological examination, leading to a diagnosis of nodular hidradenoma. This case is presented to highlight its rarity, together with its clinical features that were suggestive of malignancy but proved ultimately to be benign. 相似文献

A total of 11 Vibrio cholerae isolates from 1996-1998 outbreaks in Malaysia and 4 V. alginolyticus were analyzed. Isolates were characterized by polymerase chain reaction (PCR) and Southern hybridization for the presence of the gene encoding zonula occludens toxin (zot). Screening of zot gene by PCR revealed the presence of this gene in V. cholerae and V. alginolyticus. The zot gene from one V. cholerae Ogawa isolate that was cloned in a pCR 2.1 TOPO vector was sequenced. The sequences obtained were 99% homologous to the zot gene sequence from the Gene Bank. 相似文献

BACKGROUND: Adult-to-adult living donor liver transplantation (ALDLT) is being adopted widely in the USA and mainland Europe, fueled by the increasing waiting lists for cadaver organs. The present report describes the first UK experience with the procedure in patients from overseas who have the lowest priority for cadaver organ allocation. METHODS: The 16 patients seen over the period November 1998 to March 2002 had end-stage cirrhosis from chronic hepatitis C virus (HCV) or hepatitis B virus (HBV) infection (13 cases), with single instances of cryptogenic cirrhosis, secondary biliary cirrhosis and alcoholic liver disease. Grafts were left lobe in the first two recipients and right lobe in the subsequent 14 recipients, donated by nine sons/daughters and seven brothers/sisters. RESULTS: Twelve of the 16 recipients did well. The four recipients who died had recurrent sepsis; two of these died following hepatic arterial occlusion, and in three major surgical factors were present before transplantation. Serial computed tomography (CT) measurements in the survivors showed regeneration of the grafted lobe with final volumes reaching in each case the calculated standard liver volume for body size. In the donors, liver function tests had returned to normal by day 7-14, with rapid regeneration of the remaining lobe, although the final size attained that estimated before donation in only four donors. CONCLUSIONS: ALDLT, although requiring considerable facilities and organization, can give good results for both recipient and donor. As with cadaver grafts, outcome in the recipient if the larger right lobe is used is dependent on surgical risk factors and the severity of clinical decompensation before transplantation. Measures to ensure the safety of the donors remain the main concern. 相似文献
