An 83-year-old patient suffered a cat bite dorsally to the Achilles tendon. In the further course, he developed an isolated intratendinous abscess of the Achilles tendon, which was surgically revised twice and subsequently healed with antibiotic treatment. In Germany, about 40,000 bite injuries of different origins occur annually. Most of these injuries are cat or dog bites, while human bites are rare. Although the course is often complicated, there are no standard recommendations for treatment. An intratendinous abscess after animal bite injury has not been described in the literature as yet., Competing Interests: Interessenkonflikt: Nein., (Georg Thieme Verlag KG Stuttgart · New York.)

We report a unique case in which a 57-year-old man with an 8-year history of late recurrent post-tympanostomy tube otorrhea (PTTO) was found to harbor Bacillus subtilis, an aerobic endospore-forming bacillus that is typically resistant to chemical and physical agents because of its unique life cycle. Removal of the patient's tympanostomy tube resulted in complete resolution of his long-standing otorrhea. We also review the etiologies of and treatment strategies for early, late, chronic, and recurrent PTTO. We conclude that regardless of the etiology, a patient with persistent or recurrent PTTO should consider undergoing removal of the ventilation tube.

Pyogenic infections of the central nervous system of dental origin are quite uncommon in industrialized countries. We report six cases with intracerebral (n = 4) and intraspinal (n = 2) infections treated in our hospital. The microbial pathogen was successfully isolated in all patients. Fusobacterium nucleatum as well as Streptococcus species were found in three cases. Bacillus species were identified in two patients. Actinomyces was the etiologic agent in one case. All patients suffered from dental pathologies, so that after clinical and radiological exclusion of other sources an oral focus was presumed. Therapeutic management consisted of an operative procedure in order to obtain decompression, as well as evacuation of the pus on the one hand, followed by targeted antibiotics on the other. Clinical improvement was achieved in all patients, with one patient lost to follow-up. On magnetic resonance tomography, the inflammatory changes also disappeared in all cases. We recommend that oral infection with recurrent bacteraemia should always be considered in the pathogenesis of the so-called "cryptic" intracerebral and intraspinal infections.

The authors report a case of a cutaneous infection due to Bacillus licheniformis. It occurred after a wound due to a wicker splinter. The bacteriological identification was easy thanks to the very typical aspects of culture. First intention antibiotherapy given for bacterial dermo-hypodermatitis may be ineffective because Bacillus licheniformis secretes a biofilm and is frequently resistant to Beta-lactams.
