Introduction: The organism Sphingomonas paucimobilis formerly known as Pseudomonas paucimobilis is a strict aerobe, motile, non-spore forming, non-fermentative, Gram-negative bacillus, characterized by catalase and oxidase activities. It is an opportunistic pathogen that causes infection in healthy and immunocompromised individuals. Sphingomonas paucimobilis is ubiquitous and has been isolated from diverse sources including the hospital environment. Presentation of Case: We describe the clinical characteristics, manifestations, laboratory findings and management of hospital-acquired Sphingomonas paucimobilis sepsis in a neonate, delivered through caesarean section and brought in from postnatal ward to special care baby unit of the University of Abuja Teaching Hospital, Gwagwalada, Abuja, Nigeria. Discussion: The laboratory findings showed normal values for complete blood count, electrolytes, urea and creatinine but positive blood culture. Sphingomonas paucimobilis isolated from the blood was susceptible to Imipenem, Ampicilin-sulbatam, Azithromycin, Lincomycin, Ofloxacin, Ciprofloxacin and Sparfloxacin but resistant to Cefuroxime, Ceftazidime, Augumentin and Ampicillin. The isolation of this organism from the newborn whose laboratory tests were within normal acceptable values, and from the hospital environment is a case of hospital-acquired infection. The patient recovered and was discharged because of adequate treatment by the managing team and also low virulence of this organism. Conclusion: The study thereby recommends adequate and consistent cleaning of the newborn and maternity units of the hospital, in particular, the entire hospital equipment and its environment using a potent disinfectant to minimize the risk of hospital-acquired infections.

The Impact

Abstract Microorganisms have been shown to survive drinking water disinfection and remain viable in disinfected waters despite the presence of disinfectant residuals. This may be partially attributed to protection by particulate matter. The aim of this study was to determine the effects of the presence of particulate matter on disinfection kinetics. Sphingomonas paucimobilis ATCC 10829 and Helicobacter pylori ATCC 43504 were used in inactivation experiments in the presence and absence of soil, corrosion, and wastewater particles. The results showed that the presence of such particles tended to inhibit chlorine and monochloramine inactivation, although the magnitude of the impact under the conditions tested was small (e.g., 1-log reduction in inactivation for several minutes of contact time in the presence of less than 1 mg/L of disinfectant).

ABSTRACT Sphingomonas paucimobilis SYK-6 converts vanillate and syringate to protocatechuate (PCA) and 3-O-methylgallate (3MGA) in reactions with the tetrahydrofolate-dependent O-demethylases LigM and DesA, respectively. PCA is further degraded via the PCA 4,5-cleavage pathway, whereas 3MGA is metabolized via three distinct pathways in which PCA 4,5-dioxygenase (LigAB), 3MGA 3,4-dioxygenase (DesZ), and 3MGA O-demethylase (LigM) are involved. In the 3MGA O-demethylation pathway, LigM converts 3MGA to gallate, and the resulting gallate appears to be degraded by a dioxygenase other than LigAB or DesZ. Here, we isolated the gallate dioxygenase gene, desB, which encodes a 418-amino-acid protein with a molecular mass of 46,843 Da. The amino acid sequences of the N-terminal region (residues 1 to 285) and the C-terminal region (residues 286 to 418) of DesB exhibited ca. 40% and 27% identity with the sequences of the PCA 4,5-dioxygenase β and α subunits, respectively. DesB produced in Escherichia coli was purified and was estimated to be a homodimer (86 kDa). DesB specifically attacked gallate to generate 4-oxalomesaconate as the reaction product. The Km for gallate and the V max were determined to be 66.9 ± 9.3 μM and 42.7 ± 2.4 U/mg, respectively. On the basis of the analysis of various SYK-6 mutants lacking the genes involved in syringate degradation, we concluded that (i) all of the three-ring cleavage dioxygenases are involved in syringate catabolism, (ii) the pathway involving LigM and DesB plays an especially important role in the growth of SYK-6 on syringate, and (iii) DesB and LigAB are involved in gallate degradation.

Biofilm Development

Sphingomonas paucimobilis, an oligotroph, is well recognized for its potential for biofilm formation. The present study explored the biofilm forming ability of a strain isolated from municipal drinking water on plumbing materials. The intensity of biofilm formation of this strain on different plumbing materials was examined by using 1 × 1 cm2 pieces of six different pipe materials, i.e. polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), aluminium (Al), copper (Cu) and rubber (R) and observing by staining with the chemical chromophore, Calcofluor. To understand whether biofilm formation occurs under flow through conditions, a laboratory-scale simulated distribution system, comprised of the above materials was fabricated. Biofilm samples were collected from the designed system at different biofilm ages (10, 40 and 90 hours old) and enumerated. The results indicated that the biofilm formation occurred on all plumbing materials with Cu and R as exceptions. The intensity of biofilm formation was found to be maximum on PVC followed by PP and PE. We also demonstrated the chemical chromophore (Calcofluor) successfully for rapid and easy visual detection of biofilms, validated by scanning electron microscope (SEM) analysis of the plumbing materials. Chlorination has little effect in preventing biofilm development.
