Achromobacter xylosoxidans, subspecies denitrificans, is a gram-negative rod recently implicated as an emerging cause of infection in both immunosuppressed and immunocompetent populations. Few cases are reported in literature involving multiple body systems. Diagnosis depends on cultures of appropriate specimens, and management usually is by administration of appropriate antibiotics (usually agents with antipseudomonal activity). We report a rare case of pneumonia due to infection with this organism, in a patient with preexisting bronchiectasis secondary to chronic aspiration.

ABSTRACT Achromobacter xylosoxidans is a nonfermentative Gram-negative organism, known to cause opportunistic infection in humans. We report a case of septicemia in a 76-year-old male patient with underlying hepatocellular carcinoma due to A. xylosoxidans, which showed a different antimicrobial susceptibility pattern from what is usually reported. From aerobic blood culture of the patient, A. xylosoxidans was isolated which was found to be sensitive to amoxicillin-clavulanic acid, piperacillin-tazobactam, ceftazidime, cefoperazone-sulbactam, meropenem, minocycline, tigecycline, and trimethoprim/sulfamethoxazole. The patient recovered with amoxicillin-clavulanic acid treatment, which was given empirically to the patient. The present case highlights the possible role of amoxicillin-clavulanic acid for treatment of bloodstream infection with A. xylosoxidans.

Patients diagnosed with multiple myeloma are more susceptible to infections which are the major causes of morbidity and mortality associated to this disease. The main infectious agents involved are Gram-positive bacteria. However, after chemotherapy an increase in the incidence of Gram-negative strains is observed. These bacteria are also responsible for most cases of urinary tract infections. Here is reported a rare case in a 73-year-old man with multiple myeloma who developed endocarditis due to pseudomonas.

Sphingomonas species are ubiquitous gram-negative, aerobic bacteria frequently found in aquatic environments such as drinking water and very seldom in hemodialysis fluids or supposedly sterile drug solutions. Human infections with the gram-negative Sphingomonas species are rare and peritonitis with these organisms even rarer. Here we report a case of polymicrobial peritonitis due to Sphingomonas koreensis and Escherichia coli in a patient undergoing peritoneal dialysis (PD).

In 1971, Yabuuchi and Ohyama named and describedAchromobacter xylosoxidansas a distinctive gram-negative, nonfermentative bacillus. During the past 15 years,A xylosoxidanshas been infrequently reported in the literature as a nosocomial pathogen. The organism has usually been associated with aquatic surroundings and frequently colonizes aqueous fluids in the hospital environment, awaiting the opportunity to infect compromised patients. Several outbreaks have been reported to be caused byAchromobacter, and all have contaminated fluids as the epidemiologic “common denominator.”Achromobacteris an emerging pathogen that has been recognized and appreciated with increasing frequency during the past few years. It is a microorganism ideally suited to the hospital environment in that it is resistant to many disinfectants and most antibiotics.AchromobactermimicsPseudomonas aeruginosamicrobiologically and clinically, but may be differentiated from the latter on the basis of flagella arrangement and antibiotic suscep-tibilities.

ABSTRACT The extent to which antibiotic-resistant bacteria are excreted by humans who have not been exposed to antibiotics is not known. Children, who rarely receive fluoroquinolones, provide opportunities to assess the frequency of fecal excretion by fluoroquinolone-naïve hosts of fluoroquinolone-resistant gram-negative bacilli. Fresh nondiarrheal stools from children were processed by screening them on agar containing ciprofloxacin to recover ciprofloxacin-resistant gram-negative bacilli. Resistant isolates were identified, and ciprofloxacin MICs were determined. Resistant Escherichia coli isolates were also analyzed for urovirulence-associated loci. Thirteen (2.9%) of 455 stools yielded ciprofloxacin-resistant E. coli (seven children), Stenotrophomonas maltophilia (four children), and Achromobacter xylosoxidans and Enterobacter aerogenes (one child each). Neither the subjects themselves nor members of their households used fluoroquinolones in the 4 weeks preceding collection. Six of the seven resistant E. coli isolates belonged to phylogenetic groups B2 and D, in which extraintestinal pathogenic E. coli bacteria are frequently found. All resistant E. coli isolates contained at least three putative E. coli virulence loci. Most ciprofloxacin-resistant bacteria were resistant to additional antibiotics. Potentially pathogenic bacteria that are resistant to therapeutically important antimicrobial agents are excreted by some humans, despite these persons' lack of exposure to the particular drugs. The sources of these resistant organisms are unknown. This underrecognized reservoir of drug-resistant potential pathogens poses public health challenges.

Soft tissue infections due to gram negative microorganism are very rare. Sphingobacterium multivorum related respiratory tract infections, cellulitis, necrotizing fasciitis and septic shock have been reported in literature mostly in immunosuppressed population. We present an interesting and rare case of neck abscess due to sphingobacterium multivorum in an immunocompetent patient, diagnosed by abscess fluid culture and neck imaging and treated with course of oral antibiotics.

SUMMARYAchromobacter spp. are emerging opportunistic Gram-negative rods responsible for diverse nosocomial or community-acquired infections. We describe, for the first time, the distribution of Achromobacter spp., defined by nrdA gene sequencing, and their antimicrobial susceptibility in a variety of non-respiratory samples recovered from hospitalized patients from 2010 to 2015. Of the 63 isolates studied, A. xylosoxidans was the most prevalent (41 isolates), and with the exception of A. insuavis (four isolates), the remaining 10 species identified were represented by one or two isolates only. All isolates were uniformly susceptible to piperacillin and piperacillin-tazobactam and 97% to meropenem, but 76% showed resistance to ciprofloxacin. This study confirms the diversity of Achromobacter spp. in non-cystic fibrosis (CF) isolates and the predominance of A. xylosoxidans, as previously reported for CF sputum isolates. There was no apparent link between the clinical site of infection and the species of Achromobacter.
