“…Similarly, a more recent review suggested that most European isolates are still widely responsive to antibiotherapy [ 72 ]. While a β-lactamase gene has been discovered on the chromosome of Y. ruckeri [ 73 ], there is evidence that this gene is not likely to be expressed at high levels [ 74 ]. In vitro testing has, however, shown that Y. ruckeri readily develops resistance against oxolinic acid, oxytetracycline and potentiated sulphonamide [ 75 ].…”

Enteric redmouth disease (ERM) is a serious septicemic bacterial disease of salmonid fish species. It is caused by Yersinia ruckeri, a Gram-negative rod-shaped enterobacterium. It has a wide host range, broad geographical distribution, and causes significant economic losses in the fish aquaculture industry. The disease gets its name from the subcutaneous hemorrhages, it can cause at the corners of the mouth and in gums and tongue. Other clinical signs include exophthalmia, darkening of the skin, splenomegaly and inflammation of the lower intestine with accumulation of thick yellow fluid. The bacterium enters the fish via the secondary gill lamellae and from there it spreads to the blood and internal organs. Y. ruckeri can be detected by conventional biochemical, serological and molecular methods. Its genome is 3.7 Mb with 3406–3530 coding sequences. Several important virulence factors of Y. ruckeri have been discovered, including haemolyin YhlA and metalloprotease Yrp1. Both non-specific and specific immune responses of fish during the course of Y. ruckeri infection have been well characterized. Several methods of vaccination have been developed for controlling both biotype 1 and biotype 2 Y. ruckeri strains in fish. This review summarizes the current state of knowledge regarding enteric redmouth disease and Y. ruckeri: diagnosis, genome, virulence factors, interaction with the host immune responses, and the development of vaccines against this pathogen.

“…Schiefer et al [15] recently characterized β-lactamases of Y. frederiksenii, Y. bercovieri, Y. aldovae and Y. ruckeri and reported that except for Y. frederiksenii , all expressed only an AmpC β-lactamase. Mammeri et al [16] cloned and sequenced the complete ampC gene of Y. ruckeri and found that it shared low level of identity with the known chromosomal and plasmid AmpC enzymes of closely related members, viz ., Enterobacter cloacae, E. aerogenes and Citrobacter freundii . Much of these data however pertains to strains isolated in Europe.…”

Characteristics of β-lactamases and their genes (blaA and blaB) in Yersinia intermedia and Y. frederiksenii

et al. 2007

Background: The presence of β-lactamases in Y. enterocolitica has been reported to vary with serovars, biovars and geographical origin of the isolates. An understanding of the β-lactamases in other related species is important for an overall perception of antibiotic resistance in yersiniae. The objective of this work was to study the characteristics of β-lactamases and their genes in strains of Y. intermedia and Y. frederiksenii, isolated from clinical and non-clinical sources in India.

“…By screening the susceptibility of Y. ruckeri isolates, they were showed resistance patterns to OT, SXT, AMP, and E. Similar resistance was interpreted by Rodgers, (2001) in oxolinic acid, oxytetracycline, and potentiated sulphonamide. He has attributed it to Y. ruckeri βlactamase gene which is not likely to be expressed at high levels (Stock et al, 2002;Mammeri et al, 2006). Oppositly, Klein et al (1996) did not found resistance patterns among Y. ruckeri isolates, except for a lower sensitivity to OXA.…”

Nile Tilapia (Oreochromis niloticus) is of the most commercial fish species in Egypt and worldwide (Suresh, 2003). Despite the obstacles facing its production, but it is still considered the best native source of animal protein, which contributes to bridging the gap per capita. Disease outbreaks have been a major limitation to the dilation of aquaculture which has a significant action on the economic development in many countries (
