In a randomised, multicentric field clinical trial on dogs with otitis externa, the efficacy of an hydrocortisone aceponate-gentamicinmiconazole otic suspension (Easotic, Virbac, Carros, France) applied once daily for 5 days was compared to that of a betamethasone valerate-gentamicin-clotrimazole otic suspension (Otomax, Schering Plough Animal Health, Levallois-Perret, France) applied twice dai...

Acute otitis externa is a common condition involving inflammation of the ear canal. The acute form is caused primarily by bacterial infection, with Pseudomonas aeruginosa and Staphylococcus aureus the most common pathogens. Acute otitis externa presents with the rapid onset of ear canal inflammation, resulting in otalgia, itching, canal edema, canal erythema, and otorrhea, and often occurs foll...

Ear mites (Otodectes cynotis) and ear canal tumors are highly prevalent among federally endangered Island foxes (Urocyon littoralis catalinae) living on Santa Catalina Island off the coast of Southern California. Since studies began in the 1990s, nearly all foxes examined were found to be infected with ear mites, and ceruminous gland tumors (carcinomas and adenomas) were detected in approximate...

OBJECTIVE Aims of this study were to investigate the clinical findings and to identify causative microorganisms and their susceptibility to antibiotics in otitis externa infection. METHODS The symptoms and signs, as well as the bacterial and fungal flora from the auditory canal of one hundred and eighty patients (100 males and 80 females), age range from 6 month to 19-years old suffering from...

During a survey of the occurrence of Malassezia species in the external ear canals of cats without otitis externa, Malassezia furfur was isolated. This is the first report of the isolation of M. furfur from cats.

OBJECTIVE To isolate and characterize bacteria and fungi from acute otitis externa (AOE) and to obtain susceptibility profiles on each bacterial isolate. STUDY DESIGN Prospective core series. METHODS Specimens were collected from the external canals of subjects with clinically diagnosed acute otitis externa. Species-level identification for each bacterial isolate recovered was obtained by c...

Market collapse is one of the most dramatic events in economics. Such a catastrophic event can emerge from the nonlinear interactions between the economic agents at the micro level of the economy. Transient chaos might be a good description of how a collapsing market behaves. In this work, we apply a new control method, the partial control method, with the goal of avoiding this disastrous event...

Malassezia nana is a recently-described lipophilic yeast that has been isolated from the ear canals and skin of cats in Japan and Europe and from Brazilian cattle with or without otitis externa. Previous reports have demonstrated that significant intra-species variability exists in the DNA sequence of the intergenic spacer 1 region (IGS1), particularly amongst M. globosa, M. restricta and M. pa...
