The increasing gap between availability of solid organs for transplantation and the demand has led to the inclusion of donors which according to current guidelines may be discarded, some of them because of the possibility for transmission of infection to their recipients. We present the first report, to the best of our knowledge, of a case of a brain-dead donor with a localized and treated Actinomyces israelii central nervous system infection who, after a thorough evaluation, led to successful transplant procedures in four recipients...

Importance: Actinomyces is commonly found in many areas of the body where it derives a benefit without harming the host. When it does infect the host during pregnancy, is that infection a threat to the obstetric patient and does that infection cause adverse pregnancy outcomes? Objective: The aim of this study was to review what is known about Actinomyces infections and the impact of an Actinomyces infection on pregnancy outcomes. Evidence Acquisition: A PubMed search was undertaken with the search years unlimited to April 1, 2016, and restricted to articles in English...

Actinomycosis is caused by the Gram positive filamentous Actinomyces bacterial species that are normal commensals of the oral cavity. Due to their low virulence, disease is rare in the immune competent patient. Although it may afflict any system in the body, involvement of the musculoskeletal system is uncommon. Here in, we describe the case of a 60 year old lady presenting with low grade fever, left hip pain and drowsiness. She was diagnosed as left hip actinomycosis on Computed tomogram (CT) guided biopsy and histopathological analysis of infiltrative lesions identified on Magnetic Resonance Imaging (MRI)...

CASE: A 51 year old African American Man without significant past history presented with three weeks of persistent cough productive of copious yellow sputum. He denied fevers, chills, hemoptysis, dyspnea, weight or appetite changes, sick contacts, recent travel. On physical examination, the patient was afebrile and appeared comfortable. He had decreased air entry of the left lower lobe with dullness to percussion. A 5x3 cm fluctuant mass was incidentally found on the left anterior chest wall at the level of the 11th rib with yellow expressible exudate at which time the patient reported a minor trauma sustained 3 weeks prior...

We hypothesised that consumption of beverage rich in both fibre and polyphenols, rather than each bioactive alone, will modulate populations of selected salivary bacteria, and their adhesion characteristics and that some of these effects may be due to the anti-microbial activity of the beverage bioactives. We investigated the effect of 4 weeks' consumption of beverages, rich in apple fibre, boysenberry polyphenols, or both on salivary bacteria in healthy subjects. In this placebo-controlled crossover study, saliva samples were collected at the beginning and end of each treatment period, and used for qPCR quantitation of Lactobacillus spp...

Critical septic patients affected by necrotizing soft tissue infections (NSTI) require an early, aggressive and multidisciplinary treatment. Pharmacokinetic alterations in antibiotic therapy are peculiar in these infections. Clinical pharmacology represents a first step in this setting. We report a case of septic shock due to NSTI in which clinical pharmacology is taken into account.

A 55-year-old woman who had had the same intrauterine device (IUD) for 13 years was referred to the gynaecology outpatient clinic due to constitutional symptoms, abdominal pain and vaginal discharge. Diagnostic imaging showed multiple pelvic abscesses, and severe chronic endometritis with Actinomyces was found in an endometrial biopsy. The patient underwent surgical drainage of the accessible abscesses and started long-term antibiotic treatment. This case report illustrates that actinomycosis is an important differential diagnosis in symptomatic women with IUD and suspected gynaecologic malignancy...

The chemical oxygen demand (COD) and NH3-N removal, membrane fouling, sludge characteristics and microbial community structure in a membrane bioreactor (MBR) coupled with worm reactors (SSBWR) were evaluated for 210days. The obtained results were compared to those from a conventional MBR (C-MBR) operated in parallel. The results indicated that the combined MBR (S-MBR) achieved higher COD and NH3-N removal efficiency, slower increase in membrane fouling, better sludge settleability and higher activities of the related enzymes in the activated sludge...

Actinomycosis is an indolent, slowly progressive infection caused by anaerobic or microaerophilic bacteria, primarily from the genus Actinomyces. Thoracic involvement is observed in approximately 15% of cases of infection with actinomycosis. Here, we present a case of a 61-year-old male who presented with recurrent endobronchial actinomycosis. The case is being presented because of its rarity on three counts - endobronchial involvement, which is uncommon, recurrence in different sites in the bronchial tree, which is even rarer and development of the disease following an endobronchial procedure...

Actinomycosis is a bacterial infection due to Actinomyces israelii, a gram-positive, anaerobic organism that normally affects the cervicofacial region. However, facial injury or trauma (i.e., dental procedures) can allow this bacteria to inhabit other regions. There have been rare reports of actinomycosis of the paranasal sinuses. We present a case of a 50-year-old female who originally presented with a suspected oroantral fistula who subsequently was found to have actinomycosis involving her right maxillary sinus...

Actinomycosis is a rare bacterial disease caused by Actinomyces spp., an anaerobic bacteria from the oropharynx, digestive, and female genital tracts. Initial clinical presentation often mimics malignancy, which can lead to a delay in diagnosis. Cervico-facial, genitourinary, digestive, and respiratory features are the most frequent. Few cases are reported in children and risk factors are not well known in this population. We report on the case of an 8-year-old boy with disseminated actinomycosis with cervico-facial, pulmonary, and bone involvement caused by Actinomyces israelii...

Specific interbacterial adhesion, termed coaggregation, is well established for three early colonizers of the plaque biofilm: streptococci, actinomyces, and veillonellae. However, little is known about interactions of other early colonizers, and about the extent of interactions within the bacterial community from a single host. To address these gaps, subject-specific culture collections from two individuals were established using an intra-oral biofilm retrieval device. Molecular taxonomy (Human Oral Microbe Identification Microarray: HOMIM) of biofilm samples corroborated integrity and completeness of the collections...

Actinomycosis is a slowly progressive, chronic infectious disease. It is caused by the genus Actinomyces, which are gram-positive anaerobic bacteria. It presents as a mass-like lesion, composed of bacterial nidus and characteristic granulomatous inflammatory fibrosis. As such, it has frequently been mistaken for a malignancy. Surgical resection is a common procedure in these patients prior to a definite diagnosis. Although actinomycosis can occur in a variety of regions, including oral-cervicofacial, thoracic, and abdominopelvic cavities, the involvement of the pancreas is very rare...

RATIONALE: Chronic kidney disease (CKD) and periodontitis (PD) are important health issues. There is a large variety of microorganisms related to the pathogenesis of periodontitis, and optimising the time and the cost of laboratory assays to detect these organisms is highly valuable in the medical field. METHODS: Bacteria were isolated from saliva and oral biofilm of 30 adolescents and young adults with definite medical and dental diagnosis of CKD and PD, respectively, and proteins were extracted for microorganism identification by means of the matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) technique...

OBJECTIVE: To investigate whether the microscopic filamentous aggregates observed in radicular cysts are associated with the molecular identification of Actinomyces israelii. Moreover, to verify whether this bacterium can be detected in radicular cyst specimens not presenting aggregates. STUDY DESIGN: Microscopic colonies suggestive of Actinomyces were found in 8 out of 279 radicular cyst samples (case group). The case and control groups (n = 12; samples without filamentous colonies) were submitted to the semi-nested polymerase chain reaction to test the presence of A israelii...

Abdominal actinomycosis is a rare infectious disease, caused by gram positive anaerobic bacteria, that may appear as an abdominal mass and/or abscess (Wagenlehner et al. 2003). This paper presents an unusual case of a hemodynamically stable 80-year-old man who presented to the emergency department with 4 weeks of worsening abdominal pain and swelling. He also complains of a 20-bound weight loss in 2 months. A large tender palpable mass in the right upper quadrant was noted on physical exam. Laboratory studies showed a normal white blood cell count, slightly decreased hemoglobin and hematocrit, and mildly elevated total bilirubin and alkaline phosphatase...

Peri-implantitis caused by multispecies biofilms is a major complication in dental implant treatment. The bacterial infection surrounding dental implants can lead to bone loss and, in turn, to implant failure. A promising strategy to prevent these common complications is the development of implant surfaces that inhibit biofilm development. A reproducible and easy-to-use biofilm model as a test system for large scale screening of new implant surfaces with putative antibacterial potency is therefore of major importance...
