Potential of microbiome-based solutions for agrifood systems

Host-associated microbiomes are central to food production systems and human nutrition and health. Harnessing the microbiome may help increase food and nutrient security, enhance public health, mitigate climate change and reduce land degradation. Although several microbiome solutions are currently under development or commercialized in the agrifood, animal nutrition, biotechnology, diagnostics, pharmaceutical and health sectors , fewer products than expected have been successfully commercialized beyond food processing, and fewer still have achieved wider adoption by farming, animal husbandry and other end-user communities. This creates concerns about the translatability of microbiome research to practical applications. Inconsistent efficiency and reliability of microbiome solutions are major constraints for their commercialization and further development, and demands urgent attention

Not AvailableAim To study the association of opportunistic infection due to Myroides odoratimimus in piglets immunocompromised by porcine circovirus type 2 (PCV2) infection. Methods and Results The clinical samples (n = 101) were analysed bacteriologically. The isolates were identified by their phenotypes and MALDI TOF‐MS analysis as Myroides species. The phylogram constructed based on nucleotide sequences of the 16S rRNA gene showed identity (~99%) with the M. odoratimimus isolates. The minimum inhibitory concentration values for antibiotics revealed M. odoratimimus to be resistant against carbapenem, cephalosporins, aminoglycosides and fluoroquinolones. The presence of PCV2 in affected tissue samples was confirmed by amplification of the 565 bp region of ORF2 of the PCV2 genome. The topology of the phylogenetic tree grouped the PCV2 with cluster—2d. Conclusions PCV2 being immunosuppressive in nature might have impaired the immunity thereby increasing the susceptibility of immunocompromised piglets to opportunistic pathogens such as M. odoratimimus leading to disease severity and high mortality. The M. odoratimimus isolates were found to be multidrug resistant and evidenced for uncertain clinical relevance and hence could act as hidden source of public health hazard. Significance and Impact of the Study Myroides odoratimimus is a rarely reported human pathogen. We reported the incidence of infection due to seemingly rare isolates of M. odoratimimus causing an outbreak of pneumonia in piglets. This appears, to the best of authors' knowledge, to be the first outbreak due to Myroides recorded in animal clinical cases described in the literature.Not Availabl

Not AvailableLeclercia adecarboxylata, a Gram-negative bacillus of family Enterobacteriaceae, is an uncommonly identified pathogen isolated from environmental and clinical specimens. Most of the human infections are polymicrobial and commonly occur in immunocompromised hosts, although nosocomial infections in immunocompetent hosts have been documented. Here, we describe the case of isolation of Leclercia species as polymicrobial infection from bovine suffering from respiratory distress in Chhattisgarh state of India. The isolates were identified by their phenotypes, 16S rDNA sequencing and MALDI-TOF-MS. The isolate was found to be resistant to aminoglycosides and fluoroquinolone antibiotics and intermediate resistant to cephalosporins and evidenced for uncertain clinical relevance and could act as hidden source of public health hazard. SIGNIFICANCE AND IMPACT OF THE STUDY: Leclercia adecarboxylata is a rarely reported human pathogen. We report here the case from bovine suffering from respiratory distress; the sample yielded Leclercia species as polymicrobial culture. The isolate was found to be multidrug resistant and evidenced for uncertain clinical relevance and could act as hidden source of public health hazard. The limited literature available on this organism is reviewed, and the potential implications of findings are discussed. To the best of our knowledge, this is the first report of isolation and characterization of multidrug-resistant Leclercia species from animal clinical case from India.Not Availabl
