abstract aims: bovine mastitis continues to be the most costly disease to the dairy farmers. it dominates in iran as one of the most prevalent diseases in dairy cattle among the dairy farms. mastitis treatment with antibiotics leads to the development of antibiotic resistant strains and consumer health problem. this study was performed for the first time to analyze in vitro effects of hydro-alc...
cryptosporidium is a globally distributed protozoan parasite and one of the most common causes of infection and diarrhea in humans and cattle. the aim of the present study was to determine the species of cryptosporidium among cattle with diarrhea by a nested pcr-rflp technique at cryptosporidium oocyst wall protein ( cowp ). fecal samples from 158 calves aged 1-20 weeks were collected from 10 d...
background: addition of amino acids to the culture medium is beneficial for embryonic development in many species. objective: the objective of this study was to investigate the effects of amino acids on the in vitro maturation and embryonic development of the bovine oocyte. materials and methods: bovine ovaries were collected from a local abattoir and brought into laboratory. cumulus-oocyte com...
background: progress achieved in culture media formulations have resulted led to an improvement in maintaining the mammalian embryo in culture throughout the preimplantation and pre-attachment period. objective: the objective of this study was to evaluate the effect of various concentrations of myo-inositol during in vitro fertilization of bovine oocytes on subsequent embryo development. materi...
interferon gamma (ifn-γ) is one of the key cytokines in defining t helper 1 lymphocyte immuneresponses. in this study, the bovine ifn-γ gene was cloned from spleen tissue rna using the reversetranscription-polymerase chain reaction (rt-pcr). ifn-γ cdna was sub-cloned and expressed inmammalian expression plasmid (pcdna3.1(+)) under the control of the human cytomegalovirus (cmv)promoter. the pred...
The endogenous adaptation of economic agents, that may adjust their trade network in response to infection rates, can have the perverse effect increasing overall systemic infectiveness a disease. We study dynamical model over two geographically distinct but interacting markets, better understand theoretically mechanism at play. also discuss analogies with 2018 African Swine Fever, and provide e...
Aim The study was designed to measure the seroprevalence of viral and bacterial diseases: Infectious bovine rhinotracheitis, bovine viral diarrhea, bovine leukemia, bovine parainfluenza, bovine respiratory syncytial disease, brucellosis, and paratuberculosis among bovine of Himachal Pradesh during the year 2013-2015. Materials and Methods The serum samples were collected from seven districts ...
Human semicarbazide-sensitive amine oxidase (SSAO) is a target for novel anti-inflammatory drugs that inhibit enzymatic activity. However, progress in developing such drugs has been hampered by an incomplete understanding of mechanisms involved in substrate turnover. We report here results of a comparative study of human and bovine SSAO enzymes that reveal binding of substrates and other ligand...
BACKGROUND The objective of this study was to evaluate xenograft degradation velocity when treated with 4-hexylresorcinol (4HR). METHODS The scapula of a cow was purchased from a local grocery, and discs (diameter 8 mm, thickness 1 mm) were prepared by trephine bur. Discs treated with 4HR were used as the experimental group. Untreated discs were used as the control. X-ray diffraction (XRD), F...
background : bovine ephemeral fever (befv) is an arthropod-borne disease of cattle and water buffaloes. befv occurs seasonally in tropical, subtropical and temperate regions of africa, asia and australia. it has been known for the past decades in iran based on clinical signs but lack of an accurate diagnosis has made the real feature of disease obscured. this is the first scientific report on i...
