The aim of this study was to investigate the effects of vitamin C (vit C) and magnesium L-threonate (MgT) on the learning ability and memory of mice intoxicated with lead acetate.

Rift Valley fever (RVF) is a zoonotic, vector-borne infectious disease of ruminants and camels transmitted mainly by the Aedes and Culex mosquito species. Contact with the blood or organs of infected animals may infect humans. Its etiological factor is the Rift Valley fever virus (RVFV) of the Phlebovirus genus and Bunyaviridae family. Sheep and goats are most susceptible to infection and newborns and young individuals endure the most severe disease course. High abortion rates and infant mortality are typical for RVF; its clinical signs are high fever, lymphadenitis, nasal and ocular secretions and vomiting. Conventional diagnosis is done by the detection of specific IgM or IgG antibodies and RVFV nucleic acids and by virus isolation. Inactivated and live-attenuated vaccines obtained from virulent RVFV isolates are available for livestock. RVF is endemic in sub-Saharan Africa and the Arabian Peninsula, but in the last two decades, it was also reported in other African regions. Seropositive animals were detected in Turkey, Tunisia and Libya. The wide distribution of competent vectors in non-endemic areas coupled with global climate change threaten to spread RVF transboundarily. The EFSA considers the movement of infected animals and vectors to be other plausible pathways of RVF introduction into Europe. A very low risk both of introduction of the virus through an infected animal or vector and of establishment of the virus, and a moderate risk of its transmission through these means was estimated for Poland. The risk of these specific modes of disease introduction into Europe is rated as very low, but surveillance and response capabilities and cooperation with the proximal endemic regions are recommended.

The aim of the study was to determine the quality and significance of the magnetic resonance image of the canine knee after reconstruction in the oblique and double-oblique sagittal plane. This reconstruction and 3D images are rarely used in common protocols due to the longer study time they require. The study aimed to demonstrate significance for such diagnostic images in specific sequences in order to stimulate consideration of their more frequent use in diagnosis of diseases of the cruciate ligament in dogs.

It is very important to monitor the infection of Mycoplasma ovipneumoniae as a potential threat to the sheep industry. Southern Xinjiang is a major sheep breeding base in China, however, there is no relevant information concerning the infection of the region’s ovine stock with this bacteria at present. This study aimed to address this knowledge gap.

The world of vaccines has changed tremendously since the time of Louis Pasteur. In the present day, it is regarded as vaccinology, a discipline which includes not only the knowledge of vaccine production, strategies for its delivery and influence on the clinical course of disease and the response of the host immune system but also regulatory, ethical, economic and ecological aspects of their use. A hundred years after Pasteur created the first vaccine, there was another scientific breakthrough of great importance in this field, i. e. Sanger sequencing. Progress in genome sequencing and other molecular techniques over the intervening 40 years has been enormous. High-throughput sequencing (HTS) platforms and bioinformatics tools are becoming widely available, falling in cost, and results are achieved very quickly. They enable the construction of modern vaccines, as well as the assessment of their safety, effectiveness and impact on the host organism and the environment. These techniques can also provide a tool for quality control of vaccines. Unprecedented possibilities are opened up by the HTS technique, but limiting factors on its implementation have to be contended with such as lack of reference materials and problems with method optimisation or validation. In the face of the current COVID-19 pandemic, a significant role is allotted to this sequencing technique while an effective vaccine against the disease caused by SARS-CoV-2 is sough.

Inflammation is one of the main causes of impaired health in livestock and some of its processes weaken animal productivity and impact human health. The present study was conducted to evaluate the effect of echinacea extract (cichoric acid – CA) on yak peripheral blood mononuclear cells (PBMCs), inflammatory-related factors, and the toll-like receptor (TLR)4 signalling pathway induced by lipopolysaccharide (LPS) in these PBMCs.

The control of gastrointestinal nematodes (GINs) in small ruminants is principally dependent on anthelmintic therapy, which encounters the rising problem of anthelmintic resistance (AR) development. Veterinarians reported anthelmintic failure in several sheep farms in Arbat District, Sulaymaniyah, northern Iraq, which called for a systematic study about the efficacy of three commonly used drugs: albendazole, ivermectin, and levamisole.
