ABSTRACT

Mesenteric abscess caused by chryseobacterium meningosepticum is an extremely rare clinical entity, most often found in immunodeficient patients. Castleman disease can manifest as a mesenteric abscess. We here report the case of a 23-year-old patient admitted with generalized acute peritonitis evolving over the last 2 weeks. Abdominal ultrasound showed hypoechoic mass in the intestinal loops, without any further details. During laparotomy, pus was found in the large cavity, a mesenteric abscess was detected in the mesentery of the jejunum 35 cm from the angle of Treitz, without loop perforation and mesenteric adenopathy was found in corresponence with the abscess. Pyoculture isolated chryseobacterium meningosepticum. Histological analysis of mesenteric adenopathy biopsies showed structural anomalies, suggesting hyaline vascular type of Castleman disease. Treatment was based on incision and drainage of the abscess, with pyogenic membrane removal and abdominal cavity lavage with physiological saline solution. Chryseobacterium meningosepticum was only susceptible to Ciprofloxacin. The postoperative course was simple and the patient was discharged on postoperative day 10 after surgery. Clinical and paraclinical follow-up at 12 months did not show any other lymphadenopathy or recurrence. The purpose of this study is to show an extremely rare case of mesenteric abscess due to chryseobacterium meningosepticum associated with isolated mesenteric Castleman disease in an immunocompetent patient and management approaches.

ABSTRACT

We report an Elizabethkingia anophelis case cluster associated with contaminated aerators and tap water in a children's intensive care unit in Singapore in 2017. We demonstrate a likely transmission route for E. anophelis to patients through acquisition of the bacteria on hands of healthcare workers via handwashing.

ABSTRACT

The development of nosocomial infections by germs resistant to carbapenems inherently increases mortality, and causes an increase in health spending. The knowledge and study of these infections is important in improving epidemiological and therapeutic performance protocols. We present a descriptive study of eight patients diagnosed with tracheobronchitis (TAVM) and pneumonia (NAVM) associated with mechanical ventilation Chryseobacterium indologenes (CBI), over a period of five years. CBI isolation occurred at 11 days on average (rank 7-18) of remaining patients connected to mechanical ventilation. The average length of patients on mechanical ventilation was 36 days (range 10-140). The average ICU stay was 49 days (range 14-180). There was no death at 28 days, but the intra-hospital mortality was 2 cases (25%). Nosocomial respiratory infection secondary to CBI in mechanically ventilated patients has increased in recent years, so that should be included in the differential diagnostic of NAMV.

ABSTRACT

A 47-year-old man presented to our emergency department complaining of acute ocular pain and redness of his left eye. Ophthalmological antecedents included use of semi-rigid contact lens and primary open-angle glaucoma. Slit-lamp examination revealed a small central corneal ulcer associated with stromal inflammatory infiltrate. Scraping from the corneal ulcer was positive for Elizabethkingia meningoseptica. He was empirically treated with topical 0.5% levofloxacin and 0.3% gentamicin, and five weeks later the infection had resolved. In this case report we describe the uncommon association between contact lens and Elizabethkingia meningoseptica. Despite possible serious complications associated with this atypical agent, prompt diagnosis and adequate treatment lead to good visual prognosis.


Doente de 47 anos, sexo masculino, recorreu ao serviço de urgência por início súbito de dor ocular e hiperemia conjuntival no olho esquerdo. Os antecedentes oftalmológicos incluíam o uso de lente de contacto semi-rígida e glaucoma primário de ângulo aberto. O exame na lâmpada de fenda revelou uma pequena úlcera de córnea central associada a infiltrado inflamatório estromal. A zaragatoa da base da úlcera de córnea permitiu a identificação de colónias de Elizabethkingia meningoseptica. O doente foi empiricamente tratado com levofloxacina colírio 0,5% e pomada de gentamicina 0,3%, tendo a infecção resolvido após cinco semanas. Neste caso clínico, descrevemos a associação incomum entre lentes de contacto e Elizabethkingia meningoseptica. Apesar das possíveis complicações graves relacionadas com este agente etiopatogénico, o diagnóstico rápido e tratamento adequado permitiram um bom prognóstico visual.

ABSTRACT

We report a case of nephrostomy-associated urinary tract infection caused by Elizabethkingia meningoseptica that occurred in a patient with retroperitoneal fibrosis. Though conventional identification methods failed to detect the causative organism, it was identified on the basis of the complete sequencing of 16S rRNA. Four weeks of levofloxacin and minocycline administration successfully eradicated the infection. E. meningoseptica rarely causes urinary tract infections, and we believe that this is the first such case in which the isolate was genetically confirmed. The accurate identification of the organism is necessary for the provision of appropriate treatment and to obtain a better understanding of its epidemiology and pathogenicity.

ABSTRACT

A 42-year-old man diagnosed with gastric non-Hodgkin's lymphoma 2 years earlier, for which he had undergone treatment, presented with expectorative cough, exertional shortness of breath and left-sided chest pain of 3 months duration. Respiratory system examination was suggestive of left-sided pneumonia with pleural effusion. Routine haemogram showed leukocytosis with high erythrocyte sedimentation rate. Chest radiograph showed blunting of left-sided cardiophrenic angle. Sputum culture grew Chryseobacterium indologenes. Diagnostic thoracocentesis was suggestive of lymphomatous metastasis. Pleural fluid culture was sterile. Contrast-enhanced CT (CECT) of the thorax showed left lower lobe consolidation with bilateral pleural effusion. The patient was treated with antibiotics, following which his cough improved and total leukocyte count normalised. Sputum culture repeated after the antibiotic course showed no growth of C. indologenes. However, the pleural effusion soon aggravated along with features suggestive of multiple metastasis. The patient finally succumbed to his underlying advanced malignancy.

ABSTRACT

INTRODUCTION: There is an increase in the isolation of non-fermenting gramnegative bacilli in patients with cystic fibrosis (CF). The present study evaluates the frequency of isolates of Chryseobacterium spp., analyzing its characteristics, resistance patterns and clinical outcome of patients. METHODS: It has been collected all respiratory isolates of Chryseobacterium spp. of patients attended in the CF unit of Hospital de la Princesa for three years (march 2009-march 2012). For phenotypic and genotypic identification and sensitivity study conventional methodology was used. For the assessment of the patients lung function was considered the forced expiratory volume in one second (FEV1) and the results were analyzed with SPSS. RESULTS: There was an increase in the incidence of Chryseobacterium spp. with 17 isolates from 9 patients. Three patients had chronic colonization by this microorganism and one showed significant impairment of lung function. Seven patients showed also colonization with Staphylococcus aureus and 4 of them with Pseudomonas aeruginosa. CONCLUSION: Chryseobacterium spp. should be considered as a new emerging opportunistic pathogen in patients with CF. It is essential the clinical and microbiological monitoring of this group of patients for detection of Chryseobacterium spp. colonization and to prevent the chronic infection. In these circumstances it must assess its possible eradication, though its clinical impact is unknown. Cotrimoxazole being the best treatment option.

ABSTRACT

OBJECTIVE: To report an unusual case of keratitis in a cosmetic contact lens wearer caused by two rare organisms. METHOD: Case report. RESULTS: A 14-year-old cosmetic contact lens user presented with a paracentral corneal ulcer in her right eye. The cosmetic lenses were bought online. The cultures from corneal scrapings and contact lenses demonstrated heavy growth of Chryseobacterium meningosepticum and Delftia acidovorans. The treatment with topical ciprofloxacin and fortified gentamicin was effective, and the infection resolved with corneal scar after 5 weeks. CONCLUSION: Use of cosmetic contact lenses and buying them online is a fairly common practice among teenagers. This can lead to serious eye infection as in this case. To our knowledge, this is the first report of contact lens-related keratitis simultaneously involving these two rare organisms.

ABSTRACT

Chryseobacterium indologenes was isolated from blood samples from a 5-month-old infant with bloodstream infection. Environmental sampling was performed. Molecular typing with arbitrarily primed polymerase chain reaction demonstrated the cross-contamination of commercial distillate water. The infant was infected by this water as a result of medical assistance received during hospitalization.

ABSTRACT

Chryseobacterium meningosepticum is a lactose-nonfermenting gram-negative bacilli ubiquitously found in the natural and hospital environment. Clinical infection caused by C. meningosepticum is very rare among healthy adults. We present the case of a patient with end-stage renal disease who developed purulent pericarditis with C. meningosepticum infection, which rapidly evolved into cardiac tamponade and death. To our knowledge, this is the first case in which C. meningosepticum caused fatal purulent pericarditis in a hemodialysis patient.

ABSTRACT

Chryseobacterium meningosepticum is an uncommon pathogen causing meningitis. We report a case of adult meningitis caused by chryseobacterium meningosepticum in an 88 year old woman. Immunosuppression due to old age, diabetes mellitus and history of hypertension of 20 years duration were the concomitant factors. chryseobacterium meningosepticum was isolated both from the cerebrospinal fluid and blood cultures. This organism was sensitive to quinolones, rifampicin and resistant to many antibiotics commonly used for empiric therapy for meningitis.
