Pantoea agglomerans in Immunodeficient Patients with Different Respiratory Symptoms

The aim of this paper was to determine in 32 patients from 4 different Mexican hospitals the frequency of opportunistic bacteria in the 2010 to 2011 time period. The patients were divided in 4 groups. Group 1 included 21 HIV positive patients with acute respiratory syndrome. Four HIV positive patients with tuberculosis symptoms were included in Group 2; two patients with tuberculosis symptoms and one asymptomatic person formed Group 3. Reference Group 4 included 4 patients from whom 4 strains ofMycobacteriumspp. had been reported. The strains were isolated and identified by 16S rRNA gene amplification, API 20E and 50CH, biochemical test, and antibiotic sensitivity. The strains found were 10Pantoea agglomerans, 6Mycobacteriumspp., 6Pseudomonasspp. and 10 strains of normal floral species:Thermoactinomycetes bacterium(1),Enterococcus faecium(2),Bacillus licheniformis(1),Lactobacillus rhamnosus(2),Streptococcus oralis(2),Streptococcus anginosus(1), andEnterobacter hormaechei(1).
