There are four cases of Actinobacillus actinomycetemcomitans pulmonary infections reported in the English literature prior to 1990. We report a case of A actinomycetemcomitans pulmonary infection with invasion of overlying soft tissue, rib, and sternum. This manifestation has not been previously reported. The clinical manifestation is similar to that of Actinomyces israelii, which may be misint...

A 41-year-old female patient with symptoms of severe abdominal pain, vomiting, diarrhea, rectal bleeding, and weight loss was sent to our endoscopy unit for a colonoscopy. The full blood count revealed hemogram 8.6 g/dL and hematocrit 28%. Colonoscopic investigation revealed a fragile and bleeding tumoral mass at the level of the cecum that obstructed the lumen completely (Figure 1a). At surger...

This study aimed to compare the antimicrobial effectiveness of ethanolic extract of propolis (EEP) to chlorhexidine gluconate (CHX) on planktonic Streptococcus mutans, Streptococcus sobrinus, Lactobacillus acidophilus, Lactobacillus salivarius subsp. salivarius, Aggregatibacter actinomycetemcomitans, Prevotella intermedia, Porphyromonas gingivalis, Staphylococcus aureus, Enterococcus faecalis, ...

Despite the high incidence of odontogenic abscesses in pet rabbits, published data on the bacteriology of these infections are lacking, and clinical cultures are often ambiguous, making antibiotic choices difficult. In order to define the bacteriology of these infections, 12 rabbit mandibular and maxillary abscesses were cultured aerobically and anaerobically. All specimens yielded pathogenic b...

Ethanol extracts of eight plant species used traditionally in South Africa for the treatment of oral diseases were investigated for in vitro antimicrobial activity against oral pathogens namely Actinobacillus actinomycetemcomitans, Actinomyces naeslundii, Actinomyces israelii, Candida albicans, Porphyromonus gingivalis, Privotella intermedia and Streptococcus mutans using the disk diffusion met...

Chronic suppurative lacrimal canaliculitis is an important cause of ocular surface discomfort. Being a relatively rare condition, it is commonly overlooked and undiagnosed for long periods of time. Actinomyces israelii is classically cited as the most common causative organism of canaliculitis,1 at the same time, isolation is difficult owing to the anaerobic nature of the pathogen. Herein we pr...

BACKGROUND: Primary actinomycosis of the breast is a rare disease which may present as sinus tract or with mass-like features mimicking malignancy. Clinical presentation makes it difficult to distinguish primary actinomycosis from mastitis and inflammatory carcinoma. CASE REPORT: A 48-year-old woman presented with a mass in the left breast of 2 months duration. Physical examination was signific...

L ́actinomycose est une affection bactérienne granulomateuse, suppurative, étendue et chronique provoquée par la bactérie anaérobique gram positif Actinomyces israelii. La localisation thoracique est rare, elle peut simuler une pathologie néoplasique ou une tuberculose. Il s'agit d'un patient de 54ans sans antécédents pathologiques, qui s'est présenté avec deux tuméfactions pariétales basithoarc...
