Abstract Cows’ milk may contain two types of β-casein: A1 and A2. A1 digestion is associated with the release of β-casomorphine-7 peptide, which can cause adverse gastrointestinal effects. Two methods – high-resolution melting (HRM) and rhAmp® SNP genotyping – were developed to identify the β-casein gene (CSN2) A1 and A2 alleles directly in milk. DNA milk samples from 45 animals were examined and 10 samples were also sequenced to confirm the accuracy of the assays. The analytical sensitivities o...

Abstract Cattle babesiosis is a tick-borne disease responsible for significant losses for the livestock industries in tropical areas of the world. These piroplasms are under constant control of the host immune system, which lead to a strong selective pressure for arising more virulent or attenuated phenotypes. Aiming to better understand the most critical genetic modifications in Babesia bovis genome, related to virulence, an in silico analysis was performed using DNA sequences from GenBank. Fou...

Abstract Blocking immunoglobulin G (IgG) binding receptors on leukocytes is an established and highly recommended preventive procedure for immunological assays. Failing to prevent such nonspecific binding can lead to erroneous results. Several studies testing different blocking reagents have been performed in murine or human cells, however, there are no specific studies on bovine cells. Our study aimed to investigate the efficiency of blocking reagents to inhibit the nonspecific binding of mouse...

Proteins play different and essential roles in the human organism. Containing essential amino acids, proteins, and minerals, beef is considered the main source of protein in human nutrition. It is generally accepted that the protein profile is directly correlated to tenderness and beef pigmentation and is also related to its organoleptic properties. In the present work, it is demonstrated the changes in protein profile, differences of metal concentrations, and how metals bonded to proteins can v...

Water buffalo is important livestock in several countries in the Latin American and Caribbean regions. This buffalo species can be infected by tick-borne hemoparasites and remains a carrier of these pathogens which represent a risk of infection for more susceptible species like cattle. Therefore, studies on the epidemiology of tick-borne hemoparasites in buffaloes are required. In this study, the prevalence of Babesia bovis, Babesia bigemina, and Anaplasma marginale were determined in water buff...

En el presente trabajo se reporta por primera vez la alta prevalencia de coinfeccion por Babesia bovi s, B. bigemina y A. marginale en bufalos y se diagnostica la presencia de Babesia bigemina en bufalos del Occidente de Cuba. Se diagnosticaron las infecciones subclinicas por B. bovis , B. bigemina y A. marginale en los bufalos y se analizaron varias caracteristicas epidemiologicas de estas infecciones en los rebanos bubalinos, especificamente, los factores relacionadas con la participacion de l...

Parasitemia generated by Anaplasma marginale causes significant losses in the cattle industry. A major constraint to the effective control and management of anaplasmosis in livestock is the lack of a rapid and reliable diagnostic test to identify the parasite and allow for immediate therapy. In the present study, we developed a novel DNA-based assay for the detection of A. marginale in bovine blood samples, using loop-mediated isothermal amplification (LAMP). DNA from six cattle and hemoparasite...

Repeatability coefficients (r) for tick resistance and Babesia bovis infection levels and the correlation (ρ) between these traits were estimated in beef heifers, using artificial infestations and short intervals between measurements. Forty heifers, including 20 Bos taurus taurus (Caracu) and 20 Bos taurus indicus (Nelore) animals, were submitted to three artificial infestations with Rhipicephalus microplus larvae at intervals of 14 days. The number of standard female was counted from the 19th t...
