“…Specifically, genera containing species which were implicated in foodborne and enteric infections (Aeromonas, Arcobacter, Comamonas, and Vibrio) (Collado and Figueras, 2011;Igbinosa et al, 2012;Farooq et al, 2017; Department of Health Human Services, 2019) respiratory infections (Achromobacter, Cupriavidus, Delftia, Klebsiella, Legionella, Mycobacterium, and Sphingobacterium) (Bagley, 1985;World Heath Organization, 2007;Kalka-Moll et al, 2009;Lambiase et al, 2009;Neonakis et al, 2010;Bilgin et al, 2015;Swenson and Sadikot, 2015;Al Hamal et al, 2016), sepsis and bacteremia (Gordonia, Lysinibacillus, Myroides, Shewanella, and Sphingomonas) (Ryan and Adley, 2010;Sharma and Kalawat, 2010;Ramanan et al, 2013;Wenzler et al, 2015;Beharrysingh, 2017), opportunistic infections (Citrobacter, Chryseobacterium, Morganella, and Stenotrophomonas) (Ranjan and Ranjan, 2013;Liu et al, 2016;Imataki and Uemura, 2017;National Institutes of Health, 2018), and genera containing several antibiotic-resistant species (Pedobacter) (Viana et al, 2018) were reduced after ZVI-sand filtration. At the species level, Aeromonas hydrophila, Arcobacter cryaerophilus, Bacillus cereus, and Plesiomonas shigelloides, which cause diarrhea, vomiting, and gastroenteritis (Janda and Abbott, 1998;Janda et al, 2016;Barboza et al, 2017; United States Department of Health Human Services, 2019), Mycobacterium arupense responsible for pulmonary infections (Neonakis et al, 2010;Al Hamal et al, 2016), Eggerthella lenta and Elizabethkingia meningoseptica which cause bacteremia (Gardiner et al, 2015;Shinha and Ahuja, 2015), and pathogens causing other severe infections-Brevundimonas diminuta (antibiotic-resistant opportunistic infections) (Han and Andrade, 2005), Clostridium bifermentans (necrotizing endometritis and em...…”
