Mounier-Kuhn syndrome is a rare entity characterized by abnormal dilatation of the trachea and main bronchi (tracheobronchomegaly). Alcaligenes xylosoxidans is a non fermenting gram-negative pathogen common in extra-and intra-hospital environment, which may be related to immunosuppression states. We describe the case of a 75 years old male, ex-smoker with moderate functional obstruction, chronic respiratory failure and chronic colonization by Pseudomonas aeuriginosa. He had an infectious exacerbation of his disease, reason that previously required several hospital admissions. The patient was treated with antibiotics and his evolution was favourable with negativization in cultures of the pathogen. This is the first description of the isolation of Alcaligenes xylosoxidans as a cause of respiratory infection in a patient with Mounier-Kuhn syndrome.

This paper reports the isolation and characterization of a new o-nitrobenzaldehyde (ONBA)-degrading bacterium, Alcaligenes sp. ND1. ND1 degraded almost all ONBA (100 mg L-1) in M9 medium within 36 hours. The key enzyme(s) involved in the initial biodegradation was a constitutively intracellular enzyme(s). This bacterium has great potential utility for bioremediation.
Esse trabalho relata o isolamento e a caracterização de uma nova bactéria degradadora de o-nitrobenzaldeido (ONBA), Alcaligenes sp ND1. A bactéria ND1 decompôs todo o ONBA (100 mg.L-1) do meio M9 em 36 horas. A enzima-chave envolvida na biodegradação inicial foi uma enzima constitutiva intracelular. Esta bactéria apresenta um potencial de aplicação para bioremediação.

The purpose of the present work was to inform about the first case of meningitis associated to the bacteria Alcaligenes xylosoxidans in a patient with HIV/AIDS. The patient was a 46-year-old male, with the antecedent of have been diagnosed for HIV/ AIDS, who attended in the Hospital Universitario de Colima, Mexico, with fever, shock and meningismus. The study of the cerebrospinal fluid showed pleocytosis, elevated protein levels and hypoglycorrhachia. The culture yielded the presence of Alcaligenes xylosoxidans with sensitivity to ciprofloxacin. After 14 days of treatment with this antibiotic, the patient showed neurologic improvement and was able to continue with his outpatient antiretroviral treatment. The present case shows the importance of the inclusion of this bacterium in the differential diagnosis of the neurological infections in HIV/AIDS patients and emphasizes the importance of considering the bacterial meningitis in this population.

La bacteriemia causada por Achromobacter xylosoxidans es rara y hay poca información con repecto a su tratamiento. La mayoría de los pacientes que han desarrollado bacteriemia por Achromobacter han presentado causas predisponentes a la infección. Se informa aquí un caso de bacteriemia y neumonía adquirida en la comunidad en un paciente previamente sano. Achromobacter es usualmente resistente a amplicilina, cefalosporinas de primera, segunda y tercera generación, aminoglucósidos y quinolomas. Piperacilina sola o en combinación con tazobactama, impenem y trimetoprima-sulfametozaxol inhiben la mayoría de los aislamientos.

One hundred and thirty three non fermenting gram negative bacilli isolated out of 625 different clinical specimens were identified and characterised. Samples were exudate from chronic suppractive otits media (341), diabetic foot (117) wound (116) and blood (51). Of these isolates Pseudomonas aeruginosa 105(78.94%) predominated followed by Acinetobacter sp 8 [6.1%], Pseudomonas putrifaciens 6(4.5%), Flavobacterium sp 6(4.5%), Xanthomonas maltophilia 5(3.75%), Alkaligenes sp 3 (2.25). 31 (23.30%) were resistant to commonly used antibiotics. Amikacin 85 (63.90%) was found to be more effective than fluoroquinolones (27.8-48.12%).

Se estudiaron los microorganismos de identificacion dificil referidos al laboratorio de bacteriologia del Instituto Nacional de Salud por 5 Instituciones. En 70 casos fue posible obtener una identificacion completa y responsabilizar al microorganismo aislado como agente etiologico de un cuadro clinico. Se trataba de 28 cuadros de septicemia, 26 de meningitis, 4 respiratorios, 7 genitourinarios y 6 varios que incluyeron heridas, abcesos, y conjuntivitis. Los identificados fueron: Serratia en el 38%, Acinetobacter en el 21.4%, Moraxella en el 10%, Alcaligenes en el 8.7%, Aeromonas en el 7.2%, Listeria en el 5.7%, Estreptobacilos en el 4.3% Corynebacterium en el 4.3%, Achromabacter, Cardiobacterium y los grupos M3 y M4 aparece cada uno con el 1.4% constituyendose en verdaderas curiosidades biologicas
