    Streptococcus bovis (S. bovis) bacteria are associated with colorectal cancer and adenoma. S. bovis is currently named S. gallolyticus. 25 to 80% of patients with S. bovis/gallolyticus bacteremia have concomitant colorectal tumors. Colonic neoplasia may arise years after the presentation of bacteremia or infectious endocarditis of S. bovis/gallolyticus. The presence of S. bovis/gallolyticus bacteremia and/or endocarditis is also related to the presence of villous or tubular-villous adenomas in the large intestine. In addition, serological relationship of S. gallolyticus with colorectal tumors and direct colonization of S. gallolyticus in tissues of colorectal tumors were found. However, this association is still under controversy and has long been underestimated. Moreover, the etiological versus non-etiological nature of this associationis not settled yet. Therefore, by covering the most of up to date studies, this review attempts to clarify the nature and the core of S. bovis/gallolyicus association with colorectal tumors and analyze the possible underlying mechanisms.

    Tsukamurella spp. are a rare but important cause of intravascular catheter-related bacteremia in immunocompromised patients. The organism is an aerobic, Gram-positive, weakly acid-fast bacillus that is difficult to differentiate using standard laboratory methods from other aerobic actinomycetales such as Nocardia spp., Rhododoccus spp., Gordonia spp., and the rapid growing Mycobacterium spp. We report a case of Tsukamurella tyrosinosolvens catheter-related bacteremia in a 51-year-old haematology patient who responded to treatment with imipenem and subsequent line removal. 16srRNA sequencing allowed for the prompt identification of this organism.

    Catheter-related bloodstream infection (CRBSI) is one of the common healthcare-acquired infections imposing a high burden of morbidity and mortality on the patients. Non-tuberculous mycobacterium is a rare aetiology for CRBSI and poses challenges in laboratory diagnosis and clinical management. This is a case of a woman in her early 60s with underlying end-stage renal failure, diabetes mellitus and hypertension presented with a 2-week history of high-grade fever postregular haemodialysis, vomiting, lethargy and altered mental status.Blood cultures from a permanent catheter and peripheral taken concurrently yielded Mycobacterium senegalense, identified by matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry, which established the diagnosis of CRBSI atypically presented with concurrent acute intracranial bleeding and cerebrovascular infarction at initial presentation. She was started on a combination of oral azithromycin, oral amikacin and intravenous imipenem, and the permanent catheter was removed. Despite the treatments instituted, she developed septicaemia, acute myocardial infarction and macrophage activation-like syndrome, causing the patient's death.

    Six hundred and fifty-five central venous catheters (CVC) in 496 patients in the intensive care unit of Hospital Sultanah Aminah were studied to determine the incidence and risk factors for central venous catheter-related blood stream infection (CR-BSI). CR-BSI was diagnosed in 38 catheters, giving an incidence of 9.43 CR-BSI per 1000 catheter days. The mean duration in situ was 8.4 +/- 4.9 days for infected CVCs and 6.0 +/- 3.8 days for non infected CVCs (p = 0.001). CVCs inserted in ICU had the highest infection rate (9.4%) compared to those inserted in the operating theatre (1.4%) and ward (2.8%) (p = 0.001). The highest rate of CR-BSI occurred with 4-lumen catheters (usually inserted when patients needed total parenteral nutrition) with a percentage of 15.8%. The majority of the CVCs (97.9%) were inserted via the subclavian or the internal jugular routes and there was no statistical difference in CR-BSI between them (p = 0.83). Number of attempts more than one had a higher rate of CR-BSI compared to single attempt with percentage of 7.0% vs 4.8% (p = 0.22). The top two organisms were Klebseilla pneumoniae and Pseudomonas aeruginosa. In conclusion, the incidence of CR-BSI in our ICU was 9.43 CR-BSI per 1000 catheter days. The risk factors were duration of CVC in situ, venue of insertion and use of 4 lumen catheter for total parenteral nutrition. The site of insertion, number of lumen up to 3 lumens and the number of attempts were not risk factors.

    OBJECTIVE: To study the clinical features of non-typhoid Salmonella gastroenteritis and the incidence, risk factors and outcome of invasive complications in urban Malaysian children. To describe the serotypes of Salmonella species isolated and the pattern of antibiotic susceptibility.

    METHODOLOGY: Retrospective review of a group of 131 children with non-typhoid Salmonella gastroenteritis seen at the University Hospital, Kuala Lumpur, Malaysia from January 1994 to December 1996.

    RESULTS: Sixty-seven percent were infants below one year of age. Fever and vomiting were seen in nearly half of children. Seven children (5.3%) had invasive complications: 5 bacteraemia and 2 meningitis. Age below 6 months, fever > 38.0 degrees C, and dehydration on admission were significantly associated with invasive complications. The commonest serotypes isolated were S. enteritidis, S. paratyphi B, and S. bovis-morbificans. A total of 94-100% of isolates were susceptible to commonly prescribed antibiotics.

    CONCLUSIONS: Children with Salmonella gastroenteritis below 6 months of age who are febrile and dehydrated should be treated empirically with antibiotics until the result of blood culture is available.

    Background: The efficacy of antimicrobial central venous catheters (CVCs) remains questionable. In this network meta-analysis, we aimed to assess the comparative efficacy of antimicrobial CVC impregnations in reducing catheter-related infections in adults.

    Methods: We searched 4 electronic databases (Medline, the Cochrane Central Register of Controlled Trials, Embase, CINAHL) and internet sources for randomized controlled trials, ongoing clinical trials, and unpublished studies up to August 2016. Studies that assessed CVCs with antimicrobial impregnation with nonimpregnated catheters or catheters with another impregnation were included. Primary outcomes were clinically diagnosed sepsis, catheter-related bloodstream infection (CRBSI), and all-cause mortality. We performed a network meta-analysis to estimate risk ratio (RR) with 95% confidence interval (CI).

    Results: Sixty studies with 17255 catheters were included. The effects of 14 impregnations were investigated. Both CRBSI and catheter colonization were the most commonly evaluated outcomes. Silver-impregnated CVCs significantly reduced clinically diagnosed sepsis compared with silver-impregnated cuffs (RR, 0.54 [95% CI, .29-.99]). When compared to no impregnation, significant CRBSI reduction was associated with minocycline-rifampicin (RR, 0.29 [95% CI, .16-.52]) and silver (RR, 0.57 [95% CI, .38-.86]) impregnations. No impregnations significantly reduced all-cause mortality. For catheter colonization, significant decreases were shown by miconazole-rifampicin (RR, 0.14 [95% CI, .05-.36]), 5-fluorouracil (RR, 0.34 [95% CI, .14-.82]), and chlorhexidine-silver sulfadiazine (RR, 0.60 [95% CI, .50-.72]) impregnations compared with no impregnation. None of the studies evaluated antibiotic/antiseptic resistance as the outcome.

    Conclusions: Current evidence suggests that the minocycline-rifampicin-impregnated CVC appears to be the most effective in preventing CRBSI. However, its overall benefits in reducing clinical sepsis and mortality remain uncertain. Surveillance for antibiotic resistance attributed to the routine use of antimicrobial-impregnated CVCs should be emphasized in future trials.

    OBJECTIVE: To evaluate the yield of blood cultures and the impact of blood culture results on the adjustment of empiric antibiotic treatment in children hospitalised with community acquired pneumonia (CAP).

    METHODS: This was a prospective study conducted at a tertiary hospital in Malaysia, from 1st August 2010 until 31st July 2011. Children aged between 1 mo and 12 y who were admitted for CAP and had blood cultures performed before starting intravenous antibiotics were recruited. Children with congenital pneumonia, immunodeficiency, chronic cardiac or respiratory disorders, nosocomial pneumonia or those on corticosteroids, were excluded. Decision for admission was made by the attending Accident and Emergency physician.

    RESULTS: One hundred and seventy-one children were enrolled. The median age was 13 mo (range: 38 d-10 y 3 mo) and 59 % were males. Blood cultures were positive in 1.2 % (2/171) of patients while the contamination rate was 1.8 % (3/171). Doctors altered antibiotics based on blood culture results in only one patient.

    CONCLUSIONS: Both the yield and the impact of blood culture results on the adjustment of empiric antibiotic treatment were very small. There was a high contamination rate. The recommended practice of performing blood cultures in all children admitted with CAP should be reviewed.

    INTRODUCTION: Melioidosis is caused by Burkholderia pseudomallei, a gram-negative aerobic bacillus, found in the soil and surface water. Treating melioidosis has been a challenge in district hospitals due to high usage of broad spectrum antibiotics and prolonged hospitalisation. This study is to review the patients' demography, clinical presentations and microbiological data.

    METHODS: A 5-year retrospective study was carried out on patients admitted with culture positive for melioidosis from year 2013 to 2017 in Hospital Teluk Intan, Perak.

    RESULTS: There were a total of 46 confirmed cases of melioidosis. Majority of the patients were working in the agricultural and farming (28.6%), and factories (25.7%). Thirty-one patients had diabetes mellitus (71.1%). Presentations of patients with melioidosis included pneumonia (54.3%), skin and soft tissue infection (19.6%), deep abscesses (15.2%) and bone and joint infections (13%). An average of 5.8 days was needed to confirm the diagnosis of melioidosis via positive culture. However, only 39.4% of these patients were started on ceftazidime or carbapenem as the empirical therapy. The intensive care unit (ICU) admission rate for melioidosis was 46% and the mortality rate was 52%. Our microbial cultures showed good sensitivity towards cotrimoxazole (97.1%), ceftazidime (100%) and carbapenem (100%).

    CONCLUSION: Melioidosis carries high mortality rate, especially with lung involvement and bacteremia. Physicians should have high clinical suspicion for melioidosis cases to give appropriate antimelioidosis therapy early.

    Eighteen strains of Aeromonas hydrophila from patients with bacteraemia were investigated for possible virulence factors. Cytotoxin and haemolysin were produced by all strains, whereas cholera toxin-like factor was produced by 33% of strains only. Enterotoxin production was not detected. Haemagglutination of guinea-pig, fowl and rabbit erythrocytes was demonstrated by 83%, 67% and 61% of strains, respectively. Fucose- and mannose-sensitive haemagglutinins were predominant. None of the strains agglutinated sheep erythrocytes. Extrachromosomal DNA was detected in 17 strains, 16 of which had a plasmid (3.6-5.1 MDa), the majority being between 4.6 and 5.1 MDa.

    The incidence of infection following TEVAR is low. To the best of our knowledge, this is the first case report of post thoracic endovascular aortic repair (TEVAR) with Streptococcus viridans graft infection. A 54-year-old male underwent TEVAR for dissecting thoracic aneurysm with spinal ischaemia. He had an eventful recovery with prolonged period of stay in intensive care unit. Three months later, he presented with persistent chest discomfort and fever. Computed tomography (CT) of the thorax revealed evidence of graft infection and the blood culture grew Streptococcus viridans. The rarity of TEVAR graft infection due to Streptococcus viridans and its management are being discussed.

    Nosocomial blood stream infection (or nosocomial bacteremia) is a common problem in hospitals worldwide, including Malaysia. A three-year prospective cohort study (October 2003-March 2007) of the incidences, risk factors, and patterns of the microorganisms causing bacteremia was conducted using a validated surveillance form in three intensive care units (ICUs) in Malaysia. Center for Disease Control criteria were used to diagnose bacteremia. Patients were monitored from admission until the end point of study, which was the first detection of bacteremia in the blood in each patient. The frequency of occurrence of bacteremia with clinical symptoms was 10.7% (n=23). Bacteremia was observed to occur within a mean length of stay of 10 days in ICU. The rate of device-related infection was 10.4% per device utilization days with a device utilization rate of 95.9%/1000 patient days. The total number of patient days was 2309 and the period of device utilization was 2211 days. The common bacteria detected were extended-spectrum beta-lactamases (ESBLs) Klebsiella pneumoniae (n=6); Pseudomonas aeruginosa (n=6); Acinetobacter species (n=5); Methicillin-resistant Staphylococcus aureus (MRSA)(n=3); and (non- ESBL) Klebsiella pneumoniae (n=2). Multivariable analysis using Cox Proportional Hazard Model showed that the predictors for developing bacteremia were cancer, MRSA carriage, duration of central venous catheter (CVC) infusion, frequency change of CVC, and the administration of hydrocortisone drugs. These results indicate that a combination of nursing and medical interventions as well as patients' severity of illness could lead to bacteremia in ICU. Strategic implementation of quality assurance measures in ICUs could help to control this problem.

    Acinetobacter spp is a known nosocomial pathogen causing a wide range of clinical diseases such as pneumonia, wound infection and bloodstream infections (BSI). The clinical outcomes of acinetobacter BSI were determined by a 1:1 case control study involving 58 confirmed cases of acinetobacter BSI who were compared to other gram-negative infections. The crude mortality of acinetobacter BSI was 47.2%, which was significantly greater than other gram-negative BSI (OR 1.89, 95% CI 1.10-3.24) but there were no significant differences in attributed mortality between the two groups. We found that patients treated in intensive care units (ICU), who had longer ICU stays, who presented with shock or coagulopathy, had prior exposure to carbapenems, had mechanical ventilation, were on a ventilator for longer periods, had a nasogastric tube, had an arterial catheter or had parenteral nutrition at a significantly greater risk of mortality due to acinetobacter BSI. Patients presenting with septic shock (OR 17.95, 95% CI 3.36-95.84) or having a central venous catheter (OR 12.48, 95% CI 1.09-142.68) were independently at higher risk for mortality. Appropriateness of therapy reduced the mortality attributes of acinetobacter BSI (OR 0.197, 95% CI 0.040-0.967) but did not significantly reduce crude mortality in acinetobacter BSI patients. This study shows the importance of preventing acinetobacter BSI and the appropriate use of antimicrobial agents to reduce mortality.

    Acinetobacter spp. is a known nosocomial pathogen causing a wide range of clinical diseases mainly pneumonia, wound infections and blood stream infections (BSI). A cross sectional descriptive study was performed to determine the prevalence of Acinetobacter infection in Hospital Universiti Sains Malaysia, Kelantan (HUSM). The risk factors of Acinetobacter BSI were determined by 1:1 case control analytical study, involving fifty-eight confirmed cases of Acinetobacter BSI patients compared to the cases caused by Gram-negative bacteria. The prevalence of Acinetobacter BSI in the HUSM was 6.11% (95% CI 4.88-7.53%). The attack rate of Acinetobacter BSI was 2.77 episodes per 1000 hospital admissions. Acinetobacter BSI patients were mostly located in intensive care unit and had a longer intensive care unit stay. In univariate analysis, the risk factors for Acinetobacter BSI include prior exposure to antimicrobial agents such as penicillins, aminoglycosides and cephalosporins, mechanical ventilation, presence of nasogastric tube, arterial catheter and urinary catheter. In multivariate analysis, the independent risk factors for Acinetobacter BSI were prior treatment with cephalosporins (OR 3.836 95% CI 1.657-8.881 p=0.002) and mechanical ventilation (OR 3.164 95% CI 1.353-7.397 p=0.008). This study revealed that rational use of antimicrobial agents is of paramount importance to control Acinetobacter BSI.

    T-agglutination patterns of 190 strains of group A streptococci isolated between January 1989 and December 1993 from body fluids (10), throat culture (56), pus (51) and skin lesions (73) were determined. Mucoid colonial morphology was exhibited by 6.3% (12/190) of the strains on initial isolation. Type T-5,11,27,44 comprised 23.7%, followed by T-1,3,13,B3264 (11.1%), T-4,6 (8.4%) and T-8,25, Imp 19 (7.9%). About 42% (80/190) strains could not be characterized by T agglutination pattern. T-typing of 71 selected strains at WHO Collaborating Center, Minneapolis yielded similar results. Nineteen selected strains were further characterized by M-typing; only three strains were M-typeable. These strains were isolated from throat (M1), sputum (M5) and pus (M12). About 68% (48/71) isolates produced serum opacity factor. These data support the existence of as yet uncharacterized group A streptococcal serotypes in this region.

    Non-O1 vibrio cholerae infections are associated with sporadic cases of gastroenteritis and extraintestinal infections. Septicaemia due to non-O1 vibrio cholerae is rare and are mainly reported in adults, particularly in immunocompromised patients. We report a case of non-O1 vibrio cholerae septicaemia and gastroenteritis in an 8-year-old child. The patient presented with bloody diarrhoea, fever and severe dehydration. Non-O1 vibrio cholerae were isolated from blood and stool cultures. The clinical course was uneventful after starting appropriate rehydration and supportive therapy.

    Reports of wild great ape fatalities have been very limited, and only two have described wild orangutan deaths. We found a wounded juvenile female Bornean orangutan on 7 October 2006 in the Danum Valley, Sabah, Malaysia, and observed the individual's behavior for 7 days until her death on 13 October 2006. The 5-6-year-old orangutan, which we had observed since 2004, was wounded in the left brachium, back, and right hand. The individual's behavior changed after injury; the mean nest-nest active time became significantly shorter than before injury (from 12 h 3 min to 9 h 33 min), the mean waking time became significantly later (0552-0629 hours) and the mean bedtime became significantly earlier (from 1747 to 1603 hours). In the activity budget, resting increased significantly from 28.0 to 53.3%. Traveling and feeding decreased significantly from 23.5 to 12.7% and from 45.6 to 32.8%, respectively. The rate of brachiation during traveling and nest making decreased, whereas ground activity increased from 0 to 9%. We observed one vomiting incident and four occurrences of watery diarrhea during the 7 days before the individual died. The results of an autopsy performed by a local veterinarian suggested that the cause of death was septicemia because of Pseudomonas aeruginosa infection of the severely contaminated wounds. The morphology and distribution of the wounds suggested they had been incurred during an attack by a large animal with fangs and/or claws. This juvenile female became independent of its mother at ~4-5 years of age, slightly earlier than average. This individual might have been vulnerable to predatory attack because of her small body size (~5 kg at death) and lack of the mother's protection.

    Paraspinal abscess and spondylodiscitis due to Citrobacter koseri is a very rare condition. We report a remarkable case of Citrobacter koseri bacteraemia complicated by paraspinal abscess and spondylodiscitis in a patient who has successfully been treated in our hospital. Our patient demonstrates one of the common challenges in the practice of infectious disease medicine, wherein an innocuous presentation may and often underlie a serious infection. This case report elucidates to us that the diagnosis of a paraspinal abscess and spondylodiscitis requires a high index of suspicion in at risk patient presenting with compatible signs and symptoms.
