{{DISPLAYTITLE:''Photobacterium damselae'' subsp. ''piscicida''}}<br />
'''''Photobacterium damselae'' subsp. ''piscicida''''' (conocida anteriormente como '''''Pasteurella piscicida''''') es una bacteria [[gram-negativa]] con forma de bastón capaz de causar enfermedades en los [[pez|peces]].<br />
<br />
Fue aislada por primera vez en la [[bahía de Chesapeake]] ([[EE.UU.]]),<ref>Snieszko, S.F., Bullock, G.L., Hollis, E. and Boone, J.G. (1964) Pasteurella sp. from an epizootic of white perch (Roccus americanus) in Chesapeake Bay tidewater areas. Journal of Bacteriology 88, 1814–1815.</ref> y desde entonces se ha descrito en un gran número de especies en Europa, Asia y América del Norte, representando un factor limitante para la industria productora de pescado.<br />
<br />
== Enfermedad ==<br />
La pasteurellosis ha sido descrita también como fotobacteriosis (debido a una modificación en la posición taxonómica), siendo causada por la bacteria [[halófilo|halófila]] ''Photobacterium damselae'' subsp. ''piscicida''. Las colonias bacterianas crecen en los peces infectados en órganos como hígado, riñón o bazo, dando lugar a la aparición de granulomas blancos en las vísceras (formados por células bacterianas, [[epitelio|epiteliales]] y [[fibroblasto|fibroblásticas]]). Los síntomas característicos externos son una pérdida de peso en los peces, un oscurecimiento de la piel y necrosis localizada en las branquias, aunque alguno de ellos puede estar ausente si se da la enfermedad en forma aguda.<ref>José R. López Fernández (2011) Caracterización y desarrollo de métodos de diagnóstico molecular de bacterias asociadas a episodios de mortalidad en peces planos. Tesis doctoral, pg 22.</ref><br />
<br />
Provoca mortalidades eventuales, originando severas pérdidas en la industria de la [[piscicultura]]. La enfermedad es difícil de erradicar mediante tratamientos con [[antibióticos]] y hay evidencias de que los portadores pueden sufrir re-infección en condiciones de [[estrés]]. Este estrés está relacionado con una inadecuada temperatura y salinidad del agua, mezcla de especies, hacinamiento, falta de oxígeno, tóxicos en el medio (derivados del nitrógeno y cloro, entre otros), dieta inapropiada, etc.<br />
<br />
Este microorganismo es dependiente de la temperatura y normalmente ocurre cuando el agua supera los 18-20&nbsp;°C.<ref>Magarinos, B; Couso, N; Noya, M; Merino, P; Toranzo, AE; Lamas, J <br />
Effect of temperature on the development of pasteurellosis in carrier gilthead seabream (Sparus aurata) AQUACULTURE, 195(1-2), 2001, pp. 17-21</ref> Bajo esa temperatura, el pez es portador pero no desarrolla la enfermedad o lo hace de manera subclínica (síntomas muy leves).<br />
