The effect of triploidy and vaccination on neutrophils and B-cells in the peripheral blood and head kidney of 0+ and 1+ Atlantic salmon (Salmo salar L.) post-smolts

Triploid atlantic salmon (Salmo salar L.) post-smolts accumulate prevalence more slowly than diploid salmon following bath challenge with salmonid alphavirus subtype 3

“…These differences may however be compensating for the slightly larger cell size in triploid fish [31, 32], but could also indicate differences in the immune response in these fish groups. In conclusion, although no significant difference in the prevalence of SAV3 could be seen between triploids and diploids at the end of a 5 weeks experimental period, the virus appeared to spread more slowly through the triploid fish group.…”

Application of Bacillus probiotic to prevent Aeromonas hydrophilla infection in Clarias sp.

“…Peningkatan ini terjadi diduga karena ikan telah menunjukkan respons terhadap adanya patogen A. hydrophila Rif R dalam air. Monosit dan neutrofil merupakan sel fagosit yang dapat memfagosit sisa-sisa jaringan dan penyebab penyakit serta berperan dalam pembunuhan dan degradasi mikroorganisme sebagaimana yang dilakukan dalam penyembuhan luka (Rustikawati, 2012;Fraser et al, 2012). Penurunan mulai hari ke-14 sampai akhir penelitian diduga karena populasi A. hydrophila Rif R dalam air sudah terkontrol sehingga tidak memengaruhi kondisi sistem imun ikan.…”

Ontogeny, tissue distribution and expression analysis of IgZ in rohu, Labeo rohita in response to various stimuli

“…In teleosts a variety of leucocytes are involved in eliciting immunity following an infection (Fraser et al, 2012). B lymphocytes play an important role in adaptive immunity by producing antibodies.…”

“…B lymphocytes play an important role in adaptive immunity by producing antibodies. Anterior kidney of teleost is a major immunocompetent organ housing these leucocytes for which HKLs are widely used to study antibody response (Meloni and Scapigliati, 2000;Fraser et al, 2012;). Stimulation of fish leucocytes with different mitogens or antigen viz., concanavalin A (ConA), phorbol myristate acetate (PMA), polyinosinic polycytidylic acid (poly I:C) and formalin killed bacterial cells (FKC) is a frequently used technique to analyze expression pattern of immune molecules (Haugland et al, 2005;Chang et al, 2007;Patel et al, 2009a;Fierro-Castro et al, 2012;Román et al, 2013).…”
