Retropharyngeal abscess is a rare disorder usually seen in children as a result of upper respiratory tract infections. In adults, retropharyngeal abscess can occur as a result of local trauma (such as foreign body ingestion or instrumental procedures) and odontogenic infections. ⋯ Antibiotic therapy is a useful alternative treatment to surgery in the management of non-complicated retropharyngeal abscess.

Comparative Study[Utility of the direct culture examination (Ziehl-Neelsen) using the Bactec system for the presumptive identification of Mycobacterium tuberculosis complex, Mycobacterium avium complex, Mycobacterium xenopi, and Mycobacterium kansasii].
The usefulness of the microscopic examination of Bactec 12B and 13A growth medium as a method for the possible identification of M. tuberculosis complex, M. avium complex, M. xenopi, and M. kansasii was performed out to guide the selection of different genetic identification probes and, in the case of M. xenopi, the selection of the temperature of subcultures incubation. ⋯ The morphology of M. tuberculosis complex examined in the radiometric system in useful to differentiate this species from other microbacteria (MOTT), allowing the selection of specific probe used. Within the MOTT, M. avium complex also has morphological characteristics which are useful for its differentiation, the morphology usually described for the remaining species was frequently not observed.
