“…Other external clinical signs include anorexia, lethargy, emaciation, tendency to remain in one corner of the aquarium tank, exophthalmus, scale loss and dermal ulceration, pigmentary changes, and ascites [33] . On the other hand, the most important parasitic infection known to be associated with the induction of spinal deformities is that caused by Myxobolus spp.…”

“…Chronic infections from the M. avium complex have been well documented in a wide range of species from horses to poultry (Thorel et al 1997). Piscine species are equally vulnerable, with tremendous losses related to mycobacteriosis in aquaculture (Colorni et al 1998) as well as documented epizootics in wild populations (Sakanari et al 1983, MacKenzie 1988, Rhodes et al 2001, Gauthier & Rhodes 2009, Jacobs et al 2009). Of increasing concern is the ability of many of these nontuberculosis or environmental species to cause disease in humans, especially in individuals who are immunocompromised (Dobos et al 1999).…”

Challenge studies with Mycobacterium marinum clearly demonstrate that a poor diet affects the progression and severity of mycobacteriosis in striped bass Morone saxatilis. Fish (n = 512 total, wt = 65 ± 15 g) were inoculated intraperitoneally with 10 4 colony-forming units (CFU) g -1 body weigth (BW) or a physiological saline solution (controls) and evaluated for 8 mo. Inoculated fish fed a low-ration diet (0.15% BW d -1 ) developed a severe, systemic infection characterized by a high bacterial load (>10 8 CFU g -1 spleen) and poor granuloma formation, which commonly progressed to mortality by 6 wk. In contrast, inoculated fish fed an adequate ration diet (1% BW d -1 ) developed classic granulomatous inflammation of reduced severity and total body energy similar to that found in uninoculated controls (p > 0.05). After 4 wk, fish fed adequate rations maintained an equilibrium state throughout the study period, even though 10 6 CFU g -1 spleen mycobacteria were consistently cultured. In a second study, reactivation of an acute inflammatory state was demonstrated by placing previously infected fish on reducing diets (0.073% BW d -1). In both studies, the energetic demand of this disease was only appreciable when associated with active, severe, inflammatory states. To our knowledge, this study is the first to demonstrate the interaction of diet and mycobacteriosis in fish.

“…The clinical signs of diseases clearly suggested the possible presence of mycobacterium infection according to Wolf and Smith (1999), Ranzani-Paiva, et al (2004), Gauthier andRhodes (2009), andShukla, et al(2013). In general, the presence of granulomas and acid-fast rods (Fig 1a,b) in the infected fishes showed the same structure as those described in others species with mycobacterial infections (Heckert, et al, 2001;dos Santos, et al, 2002;Shukla, et al, 2013).…”

“…in aquaculture fishes is poorly understood. Wolf and Smith (1999) and Ranzani-Paiva, et al(2004) suggest that potential routesof infection include the ingestion of contaminated detritus, food or tissues, and through skin or gill tissue lesions, where the bacterial cells remain viable for years (Ferreira, et al, 2006 (Ferreira, et al, 2006;Gauthier and Rhodes, 2009). Significant consequences of mycobacteriosis include mortality, morbidity, and effects of subclinical infection such as decreased feed efficiency, decreased growth rates, and decreased marketability (Wolf and Smith, 2009).…”

Nile tilapia culture in Campeche, Mexico experiences sporadic and significant fish mortalities, where mycobacteriosis signs of disease are detected. Thirty fishes(30 ± 4 g) from different farms were monitored after a disease outbreak.Nile tilapia (Oreochromisniloticus) samples (60%) of spleen, liver and stomach display multiples granulomas with a thick capsule, walled off by epithelioid cells and robust acid-fast rods on the necrotic center. A great number of acid-fast bacilli where detected with Ziehl-Neelsen stain protocol. The bacteriological analysis of kidney displayed a 90% (26 organisms) of positive development in Lowenstein-Jensen medium with yellow or orange colonies when exposed to light and acid-fast rods.A 562-bp fragment confirms the positive result of the presence of the Mycobacterium spp.by PCR analysis;where phylogenetic analysis suggests that Mycobacteriumfortuitum and M. marinum were the principal mycobacterial species associated with tilapia mortality in Campeche, Mexico.
