Actinomycosis is a chronic or subacute bacterial infection characterized by large abscess formation, caused mainly by the gram-positive non-acid-fast, anaerobic, or microaerophilic/capnophilic, obligate parasites bacteria from the Actinomyces genus. Although pelvic inflammatory disease is an entity associated with the longstanding use of intrauterine devices (IUDs), actinomycosis is not one of the most frequent infections associated with IUDs. We present the case of a 43-year-old female patient who was referred to the emergency facility because of a 20-day history of abdominal pain with signs of peritoneal irritation...

Abdominal actinomycosis is a rare disease caused by different anaerobic Actinomyces species. We report the case of a 55-year-old woman who presented with a painless, slow growing, left upper abdominal mass that developed after a laparoscopic cholecystectomy. A CT scan and MRI of the abdomen revealed a desmoid tumour of the left rectus abdominis muscle.Surgical excision was performed with an uneventful postoperative course. The histological analysis of the specimen was inconsistent with a desmoid tumour and revealed an infection of Actinomyces israelii in the anterior abdominal wall that was confirmed with a microbiology culture...

INTRODUCTION: Acute appendicitis is the most common indication for an emergency abdominal surgery in the world, with a lifetime incidence of around 10%. Actinomycetes are the etiology of appendicitis in only 0.02%-0.06%, having as the final pathology report a chronic inflammatory response; less than 10% of the cases are diagnosed before surgery. Here, we present the case of a subacute appendicitis secondary to actinomycosis. CASE REPORT: A 39-year-old male presented with a twelve-day evolution of intermittent abdominal pain in the right lower quadrant, treated at the beginning with ciprofloxacin and urinary analgesic...

Paediatric actinomycosis is an infrequent infectious disease caused by Actinomyces spp. Cervicofacial infections are usually related to disruption in oral mucosal membranes. We discuss the case of a 15-year-old girl who refers an 8-month history of odynophagia and changes in her tone of voice after getting a tongue piercing. She received multiple antibiotic treatments with slight improvement. Nasopharyngeal carcinoma was diagnosed by endoscopic biopsy. The patient was referred to our Hospital for treatment but, when the biopsy was analyzed again, oncological pathology was excluded and oropharyngeal actinomycosis was diagnosed...

Periodontitis is driven by a disproportionate host inflammatory immune response induced by an imbalance in the composition of oral bacteria. It instigates microbial dysbiosis along with failed resolution of the chronic destructive inflammation.The objective of this study is to identify microbial signatures for health and chronic periodontitis at the genus level and to propose a model of dysbiosis including the calculation of bacterial ratios. DESIGN AND METHODS: Published sequencing data obtained from several different studies (196 sub-gingival samples from patients with chronic periodontitis and 422 sub-gingival samples from healthy subjects) were pooled and submitted to a new microbiota analysis using the same VAMPS (Visualization and Analysis of Microbial Population Structures) analysis pipeline to identify microbiota specific to health and disease...

Actinomycosis, an infectious bacterial disease caused by Actinomyces species, is very rare and is characterized by contiguous spreading, subacute to chronic granulomatous inflammation and the formation of multiple abscesses and sinus tracts that may discharge sulfur granules. Actinomycosis that presents on the skin without endogenous origin is called primary cutaneous actinomycosis, and the occurrence and treatment of primary cutaneous actinomycosis is rarely reported. This report describes the treatment of primary cervicofacial actinomycosis with a literature review, and emphasizes the importance of surgical option for complete remission of the disease...

Actinomycosis is a slowly progressive infection caused by anaerobic bacteria, primarily from the genus Actinomyces. Primary actinomycosis of the breast is rare and presents as a mass like density which can mimic malignancy. Mammography, ultrasonography and histopathologic examination is required for diagnosis. Treatment should consist of high doses of antibacterials for a prolonged period of time and possibly surgical drainage. Primary actinomycosis infections are commonly caused by A. israelii. Actinomyces neuii is a less common cause of classical actinomycosis...

High salinity frequently causes inhibition and even failure in anaerobic digestion. To explore the impact of increasing NaCl concentrations on biogas production, and reveal the microbial community variations in response to high salinity stress, the Illumina high-throughput sequencing technology was employed. The results showed that a NaCl concentration of 20 g/L (H group) exhibited a similar level of VFAs and specific CO2 production rate with that in the blank group, thus indicating that the bacterial activity in acidogenesis might not be inhibited...

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)...

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...
