Abstract
Mastitis je vrlo važniji problem koji dovodi do velikih ekonomskih gubitaka u mliječnoj industriji diljem svijeta. Liječenje mastitisa je teško i skupo te se, stoga, selektivnim uzgojem nastoji poboljšati otpornost na mastitis. Toll like receptori (TLR) su sastavni dio imunosnog sustava, to su transmembranske bjelančevine koje prepoznaju sastavne dijelove raznih patogena i aktiviraju imunološki odgovor. Toll like receptor 4 (TLR4) prepoznaje lipopolisaharide koji su sastavni dio mnogih Gram-negativnih bakterija, a i nekih Gram-pozitivnih bakterija. Iako postoje mnoga istraživanja, njegovi temeljni molekularni mehanizmi i uloga u pojavi mastitisa nisu jasni. U ovom radu istraživana je prisutnost, učestalost i utjecaj polimorfizma c.9421 C>T TLR4 gena na sastav mlijeka i BSS u prvoj laktaciji holštajn frizijskih krava. Polimorfizam je prisutan u istraživanih krava s jednakom učestalosti oba alela (0,5) i najučestalijim TC genotipom. Nisu pronađene statistički značajne razlike za količinu mlijeka, mliječne masti i bjelančevina, udio mliječne masti i bjelančevina te BSS među genotipovima istraživanog polimorfizma. Navedeni nedostatak statistički značajne razlike može biti uzrokovan malim brojem krava u konačnoj analizi.
Abstract (english)
Mastitis is a very serious problem that leads to large economic losses in the dairy industry worldwide. Treatment of mastitis is difficult and expensive, therefore selective breeding is used to improve the resistance to mastitis. Toll-like receptors (TLR) are an integral part of the immune system, they are transmembrane proteins that recognize components of various pathogens and activate the immune response. Toll like receptor 4 (TLR4) recognizes lipopolysaccharides, which are an integral part of many Gram-negative bacteria and some Gram-positive bacteria. Although there are many studies, its underlying molecular mechanisms and role in the occurrence of mastitis are still unclear. In this study, we investigated the presence, frequency and influence of the c.9421 C>T TLR4 gene polymorphism on milk composition and somatic cell count (SCC) in the first lactation of Holstein Friesian cows. The studied polymorphism had an equal frequency of both alleles (0.5). The most frequent genotype was TC. Statistically significant differences were not found for milk, fat and protein qunatities, fat and protein shares, and SCC between the genotypes. This lack of statistically significant difference may be caused due to the small number of cows in the final analysis.
