Based on the cultural characteristics, morphological tests, and biochemical tests (Table 2), these selected bacterial isolates were assigned to three genera, namely, Aeromonas
A total of 80 bacterial isolates were collected including salmonella, shigella, vibrio, aeromonas
and E.coli, 46 (57.5%) were collected during March to December-2013 and 34 (42.5%) were collected during January to November-2014.
"These include group A Streptococcus [group A strep], Klebsiella, Clostridium, Escherichia coli, Staphylococcus aureus, and Aeromonas
hydrophila, among others.
En menor proporcion se identificaron las especies: Aeromonas
hidrophyla, Pseudomonas fluorescens, Burkolderia cepacea y Chryseobacterium indologenes (Tabla 7).
Microbiological analyses of the culture water were performed in the beginning and on the 40th experimental day (soon after the middle of the period), comprising the number of Aeromonas
This ORF, named metachi18A, shares 99% amino acid identity with a glycosyl hydrolase from Aeromonas
jandaei [RefSeq: WP_042029877.1] not yet characterized biochemically.
Additionally, several bacterial isolates identified as opportunistic pathogens show resistance to different antibiotics, for example, Aeromonas
hydrophila (Amp and Amp/Sbt), Achromobacterxylosoxidans (Amp/Sbt, Gen, Na, and Nit) Serratia marcescens (Cef and Nit), Elizabethkingia meningoseptica (Amp, Amp/Sbt, PpC/Tzba, Gen, and Nit), and Pseudomonas fluorescens (Amp, Amp/Sbt, Na, and Nit) (Table 2).
The genus Aeromonas
is characterized by Gram-negative bacilli that are facultative anaerobes.
hydrophila is a known free living pathogen that not only causes infections to human and animal but also influences the economics of fisheries department.
Chinese herbs (Astragalus membranaceus and Lonicera japonica) and boron enhance the non-specific immune response of Nile tilapia (Oreochromis niloticus) and resistance against Aeromonas
