ABSTRACT
Enteric gram-negative bacteria-associated peritoneal dialysis (PD) peritonitis is common. These organisms are such as Escherichia coli, Klebsiella and Enterobacter species. Pantoea dispersa belongs to the order Enterobacterales, it has known benefits and a role in agricultural and environmental biotechnology. Pantoea dispersa, although still relatively rare, is being increasingly recognised to cause human infections. We are reporting a case of PD peritonitis caused by Pantoea dispersa in a kidney failure patient on continuous ambulatory peritoneal dialysis (CAPD). His peritonitis was treated well with intraperitoneal antibiotics and the patient can resume his CAPD therapy. The increasing reports of Pantoea dispersa-related human infections warrant concerns, both in immunocompromised and immunocompetent patients.

Pantoea agglomerans es un bacilo gramnegativo reportado principalmente en heridas penetrantes, infecciones neonatales o como contaminante. La infección relevante por esta bacteria es rara. Nuestra revisión de la literatura sugirió una asociación consistente entre la infección por Pantoea agglomerans en pacientes inmunodeprimidos y una neoplasia maligna previamente diagnosticada. Los autores describen un derrame pleural paraneumónico en el que el aislamiento de Pantoea agglomerans permitió el diagnóstico de novo de cáncer de pulmón
Pantoea agglomerans is a gram-negative rod reported mainly in penetrating wounds, neonatal infections or as a contaminant. Relevant infection by this bacterium is rare. Our review of available literature suggested a consistent association between Pantoea agglomerans infection in immunocompromised patients and previously diagnosed malignancy. The authors describe a parapneumonic pleural effusion in which the isolation of Pantoea agglomerans allowed for de novo diagnosis of lung cancer

La infección por Pantoea agglomerans es muy rara de forma global y particularmente en Pediatría. La mayoría de las infecciones que causa son nosocomiales en pacientes inmunodeprimidos. Se han descrito infecciones articulares tras punción con espinas vegetales dando lugar a artritis, sinovitis u osteítis; meningitis o septicemia neonatal tras la contaminación de la nutrición parenteral o transfusiones de hematíes; infecciones de orina o respiratorias y peritonitis. En inmunocompetentes las infecciones son excepcionales, por lo que se aconseja realizar estudio de inmunidad, como en nuestro caso. El germen es muy resistente a antibióticos betalactámicos y para erradicarlo suele ser necesario tratar según antibiograma
Pantoea agglomerans infections are very rare globally and particularly in Pediatrics. Most of them are nosocomial and affect immnunosuppresed patients. Articular infections have been described after puncture with plant thorns giving rise to arthritis, synovitis or osteitis; they also can cause meningitis or neonatal septicemia after contamination of parenteral nutrition or red blood cell transfusions; urinary or respiratory infections, and peritonitis. In immunocompetent patients the infections are exceptional, so it is advisable to perform an immunity study, as in our case. The germ is very resistant to beta-lactam antibiotics and to eradicate it, it is usually necessary to treat according to antibiogram

This study aimed to verify the presence of members from the Enterobacteriaceae family and determine antimicrobial susceptibility profiles of the isolates in canaries bred in northeastern Brazil; in addition, the presence of diarrheagenic Escherichia coli (DEC) and avian pathogenic Escherichia coli (APEC) was also verified in these birds. Samples were collected during an exhibition organized by the Brazilian Ornithological Federation in July 2015 in Fortaleza, Brazil. A total of 88 fecal samples were collected and submitted to pre-enrichment step using buffered peptone water, followed by enrichment with the following broths: brain-heart infusion, Rappaport-Vassiliadis, and Selenite-Cystine. Subsequently, aliquots were streaked on MacConkey, brilliant green and salmonella-shigella agar plates. Colonies were selected according to morphological characteristics and submitted to biochemical identification and antimicrobial susceptibility tests with disk-diffusion technique. E. coli strains were evaluated for the presence of eight DEC genes and five APEC genes through conventional polymerase chain reaction (PCR) screening. The most frequent species observed were Pantoea agglomerans (25%), Serratia liquefaciens (12.5%), and Enterobacter aerogenes (9.1%). A single rough strain of Salmonella enterica subsp. enterica was identified in one sample (1.1%). High resistance rates to amoxicillin (78.7%) and ampicillin (75.4%) were identified. Polymyxin B (9.8%), gentamycin (6.6%), and enrofloxacin (6.6%) were the most efficient antibiotics. The total number of multidrug-resistant strains (isolates resistant to more than three antimicrobial classes) was 23 (37.7%). Four E. coli strains were tested for the virulence genes, and two were positive for APEC virulence genes: one strain was positive for iutA and the other for hlyF. In conclusion, canaries in northeastern Brazil participating in exhibitions may present Salmonella spp., Escherichia coli and other enterobacteria in the intestinal microbiota with antimicrobial resistance. These results indicate that, although the E. coli strains recovered from canaries in this study have some virulence genes, they still do not fulfill all the requirements to be considered APEC.(AU)
O objetivo deste trabalho foi verificar a presença de enterobactérias e determinar o perfil de sensibilidade aos antimicrobianos dos isolados oriundos de canários belgas criados em cativeiro do Nordeste do Brasil, adicionalmente verificou-se a presença de Escherichia coli diarreiogênicas (DEC) e E. coli patogênica aviária (APEC) nesses animais. A colheita das amostras ocorreu durante uma exposição de canários belgas organizada pela Federação Ornitológica do Brasil (FOB), em julho de 2015, na cidade de Fortaleza, Ceará, Brasil. Um total de 88 amostras de fezes foram coletadas e submetidas a pré-enriquecimento utilizando água peptonada, caldo de enriquecimento Brain Heart Infusion, Rappaport-Vassiliadis e Selenito-Cistina. Fez-se triagem em placas de ágar MacConkey, Verde Brilhante e ágar Salmonella Shigella. As colônias foram selecionadas e submetidas à identificação bioquímica e susceptibilidade antimicrobiana. Estirpes de Escherichia coli foram avaliadas quanto a presença de 8 genes de virulência de DEC e cinco de APEC por reação em cadeia da polimerase convencional (PCR). As enterobactérias encontradas com maior frequência foram Pantoea agglomerans (25%), Serratia liquefaciens (12,5%) e Enterobacter aerogenes (9,1%). Uma única estirpe de Salmonella enterica subsp. enterica (rugosa) esteve presente em um dos isolados (1,1%). Altos percentuais de resistência foram encontrados para dois antibióticos: amoxicilina (78,7%) e ampicilina (75,4%). Polimixina B (9,8%), gentamicina (6,8%) e enrofloxacina (6,5%) foram os antibióticos com melhor eficiência. O total de estirpes multirresistentes (a mais de três classes de antimicrobianos) foi de 23 (37,7%). Das quatro estirpes de E. coli isoladas, duas foram positivas para os genes de APEC, sendo uma estipe para o gene iss e outra para os genes iutA e hlyF. Portanto, canários belgas criados em cativeiro no Brasil que participam de exposições podem apresentar Salmonella spp., Escherichia coli e outras enterobactérias em sua microbiota intestinal com resistência antimicrobiana. Estes resultados indicam que as estirpes de E. coli isoladas de canário belga no presente estudo apresentam alguns, mas não todos, genes de virulência para serem caracterizadas como E. coli patogênica para aves (APEC).(AU)

Twenty four bacterial strains from four different regions of mud volcano and lime cave were isolated to estimate their diversity, plant growth promoting and biocontrol activities to use them as inoculant strains in the fields. An excellent antagonistic effect against four plant pathogens and plant growth promoting properties such as IAA production, HCN production, phosphate solubilization, siderophore production, starch hydrolysis and hydrolytic enzymes syntheses were identified in OM5 (Pantoea agglomerans) and EM9 (Exiguobacterium sp.) of 24 studied isolates. Seeds (Chili and tomato) inoculation with plant growth promoting strains resulted in increased percentage of seedling emergence, root length and plant weight. Results indicated that co-inoculation gave a more pronounced effects on seedling emergence, secondary root numbers, primary root length and stem length, while inoculation by alone isolate showed a lower effect. Our results suggest that the mixed inocula of OM5 and EM9 strains as biofertilizers could significantly increase the production of food crops in Andaman archipelago by means of sustainable and organic agricultural system.

We here in report a case of bilateral endogenous endophthalmitis caused by Pantoea agglomerans (P. agglomerans) in a patient who had interstitial lung disease and was treated with oral corticosteroids. A 72-year-old man presented with decreased visual acuity in both eyes nine days after he received oral corticosteroids. He had marked uveitis, cataracts, and vitreous opacities. Cultures were taken of blood, aqueous humor, and vitreous. We initially suspected a fungal etiology and treated him with antifungal drugs; however, the intraocular disease progressed without improvement. Vitreous culture was positive for P. agglomerans. The patient underwent pars plana vitrectomy with cataract surgery bilaterally, followed by a 2-week course of antibiotics. The final visual acuity was 20/25 in the right eye and 20/200 in the left eye. This is the first report of bilateral endogenous endophthalmitis caused by P. agglomerans in Korea; it is also the first case reported outside of the United States.

A previously healthy 50-year-old man was transferred to our hospital for evaluation of acute inflammation in his right eye after ocular trauma while using a grass mower. Slit lamp examination showed 1 mm-length full thickness corneal laceration without leakage, 4+ cells and inflammatory membrane in the anterior chamber, 10% hypopyon, posterior synechiae formation, and cataract change. Upon orbital computerized tomography, a metallic intraocular foreign body in the lens was indentified. Vitrectomy, phacoemulsification, foreign body removal, anterior chamber irrigation, and intravitreal antibiotics injections of vancomycin and ceftazidime were performed. In a culture of humor from the anterior chamber grew Pantoea species. More procedures were performed, including intravitreal antibiotics injection of ceftazidime. Upon administering a course of intravenous ceftazidime, fortified ceftazidime and moxifloxacin eye drops, and oral prednisolone, the patient improved.

Pantoea agglomerans is a Gram-negative bacterium whose isolates can be found in blood cultures and other secretions. This article described one outbreak of sepsis due to this bacterium in the pediatric urgent care center of a tertiary hospital, in Brasilia, Federal District. This was a case-control study and it evaluated the risk factors for acquisition of nosocomial sepsis caused by Pantoea agglomerans. Six case-patients and 15 control-patients have been found. The risk factors were: vomiting in the internment and presence of solution compositions in the intravenous hydration therapy received in bigger number than 2 compositions. The transference tube used for the compositions was contaminated with Pantoea agglomerans, characterizing the outbreak with common source. The evolution of all the patients was favorable.
