, suggesting recovered isolates were genetically diverse and not due to non-clonal expansion. The findings of this study are an indication that contaminated foods can be a reservoir for enteric pathogens and a source of AMR strains.Bacteriocins have become biological weapons against harmful food pathogens and have attracted interest as tools for biopreservation. The aim of this study was to isolate, identify and characterize lactic acid bacterial (LAB) strains from cheese samples, partially purify potential bacteriocins and characterize their antimicrobial activity against pathogens. Bacteriocin-producing organisms were screened by Agar spot assay test. Initially, 25 LAB isolates were isolated from the cheese samples and identified as Lactobacillius spp., among them five strains were able to produce bacteriocin whose antimicrobial activates were analysed by agar-well-diffusion assay test against pathogenic organisms. Bacillus subtilis, Bacillus cereus, Staphylococcus aureus, Streptococcus thermophillus and Listeria monocytogens were inhibited, while Enterococcus faecalis, Salmonella typhi, Escherichia coli and Pseudomonas aeruginosa were resistant to the antimicrobial substances from LAB isolates. For optimal production of bacteriocin, LAB broth cultures were harvested at exponential phase. The molecular weights of the bacteriocins are between 7.0-15.0 kDa. The bacteriocins were characterized on the basis of their sensitivity to heat, pH, enzymes, NaCl and treatments with organic solvents. These results revealed that the bacteriocins from Lactobacillius spp. isolated from the cheese might have potential antimicrobial properties and give new insight in the development of bio-preservative agents to prevent and control pathogenic bacterial infection.
Percutaneous patent foramen ovale (PFO) closure has been well established in the secondary prevention of cryptogenic stroke with overall low rates of procedural complications. One such complication is PFO closure device thrombus formation which is now rarely reported with newer generation devices.

We present the unusual case of a 59-year-old woman with myelofibrosis who developed late-onset recurrent embolic strokes related to Amplatzer PFO closure device thrombus whilst therapeutically anticoagulated on Warfarin. Surgical management was deemed too high risk and our patient was conservatively managed with enoxaparin. Serial transthoracic echocardiography demonstrated a reduction in thrombus size and the patient had no further neurological events.

Overall, the risk of serious complications following percutaneous PFO closure, such as device-associated thrombus, remains low. The risk of thrombus formation in patients with hypercoagulable states is not well characterized. Despite good evidence for the efficacy in preventing recurrent cryptogenic stroke, the role of PFO closure in addition to anticoagulation is unclear. Given this uncertain benefit of PFO closure in anticoagulated patients and the unclear risk profile, patient selection, and thorough pre-procedural evaluation are vital when assessing the appropriateness of percutaneous PFO closure.

A papillary fibroelastoma of the aortic valve has been reported as a rare cause of myocardial ischaemia. An advanced combined interventional and surgical approach leading to sufficient therapy for the patient is presented in this case report.

A 56-year-old female patient presented in an emergency room of a hospital with an acute coronary syndrome. Over 1.5 years, recurrent stable angina had been known in the patient and significant coronary artery disease has already been ruled out in a previous coronary angiogram. The patient was immediately transferred to the catheter laboratory due to cardiogenic shock where a drug-eluting stent was implanted to, firstly, recanalize the left main coronary artery (LMCA) and, secondly, to protect the left main ostium from obstruction by an echocardiographic-proven mass. During subsequent deterioration of haemodynamics caused by decreasing left ventricular function and acute severe mitral insufficiency, firstly an intra-aortic balloon pump and secondly a veno-arterial extracorporeal membrane oxygenation was established through the femoral vessels. Raf tumor The patient was transferred to our cardiac surgery unit and was successfully operated utilizing a valve-sparing technique by extracting the tumour mass from the left coronary cusp and extracting the stent carefully from the LMCA. Histology revealed a papillary fibroelastoma.

A papillary fibroelastoma of the aortic valve with intermittent obstruction of the coronary arteries requires surgical therapy. Interventional recanalization and extracorporeal support might be useful strategies to ensure the patient's safety as a bridge to surgery.

Right-sided tricuspid valve (TV) endocarditis can be difficult to identify and may be under-recognized in the absence of traditional risk factors. While generally identified with aortic valve pathology, infective endocarditis that extends beyond the leaflets of the TV have been reported to cause conduction disease.

We present the case of a 63-year-old patient who presented with haemodynamically unstable complete heart block requiring temporary venous pacemaker support. Despite the absence of traditional risk factors or significant valvular disease on transthoracic echocardiogram, she was found to be persistently bacteraemic and subsequent transoesophageal echocardiogram identified large vegetation on the septal leaflet of the TV. Conduction disease was noted to reverse with antibiotic therapy and resolution of bacteraemia.

Although rare, right-sided endocarditis involving the triangle of Koch may present with conduction disease due to local inflammation and mechanical compression. Conduction disease associated with right-sided disease appears to be readily reversible with medical therapy and temporary device support may be appropriate in the acute setting.

Right heart thrombus (RHTh) complicated by pulmonary embolism (PE) usually presents as a medical emergency with significant haemodynamic instability. However, less is known about subacute presentations.

We present a 74-year-old haemodynamically stable gentleman with a 3-week history of mild pleuritic chest pain and exertional dyspnoea preceded by lower respiratory tract infection. Early trans-thoracic echocardiogram (TTE) revealed a 3 cm elongated tricuspid valve thrombus with right ventricular dysfunction, new-onset atrial fibrillation, and new-onset severe left ventricular impairment. Subsequent computed tomography pulmonary angiogram showed widespread bilateral pulmonary emboli with retrograde opacification of the hepatic veins. The RHTh successfully resolved with warfarin therapy with no further complications, and the patient was discharged on Day 8 of hospitalization.

An early TTE is crucial in detecting the RHTh in patients suspected of PE and can significantly change the management compared with uncomplicated PE. The index of suspicion for PE and RHTh should remain high even in subacute cases.

Scimitar syndrome is a rare congenital disease characterized by partial or total anomalous pulmonary venous return from the right lung into the systemic venous system, and accounts for 0.5-2% of all congenital heart disease. Severe forms of the disease are diagnosed in childhood. However, because of the benign form of the syndrome in adults, many are asymptomatic, or present only mild symptoms including exertional dyspnoea, arrhythmias, and respiratory infections. We report an atypical presentation with hepatomegaly.

A 24-year-old woman was evaluated for abdominal discomfort. Physical examination revealed a remarkable hepatomegaly. Chest X-ray revealed dextroversion, enlargement of the right cavities, and a curvilinear opacity known as 'scimitar sign'. A transthoracic echocardiography demonstrated right ventricular dilation and a venous collector draining into right suprahepatic vein, which was severely dilated, with large hepatomegaly. Scimitar syndrome was confirmed by magnetic resonance imaging (MRI). modalities, such as echocardiography, MRI, or computed tomography. Corrective surgery may relieve the symptoms related to liver congestion at follow-up.
Left main coronary artery (LMCA)-acute coronary syndrome (ACS) is a rare complication of a floating thrombus in the ascending aorta. However, diagnosing the aetiology of LMCA-ACS during an emergency situation is challenging. We present a rare case of LMCA-ACS caused by a large thrombus in the ascending aorta, confirmed by intravascular ultrasound (IVUS).

A 90-year-old woman presented to the emergency department complaining of chest pain and syncope. On admission, her electrocardiogram showed normal sinus rhythm and a complete right bundle branch block with significant ST depression in the V3-V6 leads; hence, ACS was suspected. The first emergency angiogram of the left coronary artery showed filling defect in the proximal ascending aorta. IVUS revealed a large thrombus in the ascending aorta. The thrombus extended from the ascending aorta to the proximal left anterior descending coronary artery. IVUS confirmed that there was no dissection of the coronary artery or the proximal ascending aorta. Based on the IVUS findings, this case was diagnosed as ACS of the LMCA caused by a floating thrombus in the ascending aorta.

This rare case of LMCA-ACS caused by a thrombus in the ascending aorta was confirmed by IVUS, which can be a useful imaging tool for diagnosing morphological abnormalities during emergencies.

, a bacterium found in the oral cavities of healthy cats and dogs, is rarely reported as a cause of infective endocarditis. In this report we describe such a case in a young, male dog owner who presented acutely unwell in heart failure.

A 47-year-old male presented with a subacute onset of fever, night sweats, weight loss, dyspnoea, and peripheral oedema. On clinical examination typical features of infective endocarditis, heart failure, and aortic regurgitation were found. The patient had no conventional risk factors for infective endocarditis but was a dog owner. Transthoracic echocardiography revealed vegetations on the right coronary and non-coronary cusps of the aortic valve causing severe eccentric aortic regurgitation and left ventricular dilatation. Initial blood cultures taken prior to the initiation of antimicrobial therapy showed no growth. The patient underwent aortic valve and root replacement and a 16S ribosomal RNA polymerase chain reaction (16S rRNA PCR) of the resected aortic valve tissue, using the additional primer set 785F/1175R targeting the V5-7 region of 16S rRNA, identified
