Seal parapoxvirus (SPPV) infection has been reported among pinnipeds in aquaria in Japan; however, its seroprevalence is unknown. Therefore, an enzyme-linked immunosorbent assay (ELISA) was developed for serological diagnosis of SPPV infection.

African swine fever virus (ASFV) causes one of the most dangerous diseases of pigs and wild boar – African swine fever (ASF). Since its second introduction into Europe (in 2007), the disease has been spreading consistently, and now ASF-free European countries are at risk. Complex interactions between the host’s immune system and the virus have long prevented the development of a safe vaccine against ASF. This study analysed the possibility of neutralisation of the ASFV in vitro by sera collected from ASF-survivor animals.

Dairy cows may infrequently give milk tinged with blood after calving, which is a condition termed haemolactia. Economic losses for dairy farmers are caused by cases of haemolactia because of the condemnation of such milk, potential contamination of good bulk tank milk with haemolactic milk, and need for veterinarian intervention. This study was performed to elucidate the oxidative status of dairy cows with haemolactia during the peripartum period.

2022
Deng Chao-Yang | Zhu Ting-Ting | Lian Shuai | Wang Jian-Fa | Wu Rui | Zheng Jia-San
Hypoxia is a common pathological condition after spinal cord injury. Oestrogen-related receptor alpha (ERRα), as a key regulator of energy metabolism and mitochondrial functions, plays an important role in maintaining cell homeostasis. However, its role in hypoxic spinal microglia has not been fully elaborated. This study investigated the receptor’s activity when these cells are hypoxic and used as an in vitro model.

2022
Wang Wenjia | Li Rongling | Ye Tingzhu | Zhang Xinxin | Chen Chao | Liang Ai-xin | Yang Li-guo
Clinical mastitis (CM) is one of the most common diseases of dairy cows globally, has a complex aetiology and recurs easily. Staphylococcus aureus is a frequently isolated pathogen responsible for bovine mastitis and remains difficult to eradicate.
Mostrar más [+] Menos [-]Protective effects of Bacillus subtilis fermentation extract against ochratoxin A-induced nephrotoxicity and immunotoxicity in broiler chickens Texto completo
2022
Elhady Mohamed A. | Khalaf Abdel Azeim A. | Ibrahim Marwa A. | Hassanen Eman I. | Abdelrahman Rehab E. | Noshy Peter A.
Ochratoxin A (OTA) is a mycotoxin notably produced by Aspergillus and Penicillium spp. Bacillus subtilis fermentation extract (BSFE) contains specific enzymes which hydrolyse OTA. This study evaluated the efficiency of BSFE in ameliorating the immunotoxic and nephrotoxic effects of OTA in broiler chickens.

2022
Czyżewska-Dors Ewelina | Wierzchosławski Karol | Pomorska-Mól Małgorzata
This study aimed to determine the profile of immunoglobulins and cortisol concentrations in serum around the periparturient period in sows suffering from postpartum dysgalactia syndrome (PDS) and in healthy sows.

Rola-Łuszczak Marzena | Materniak-Kornas Magdalena | Kubiś Piotr | Pluta Aneta | Smagacz Marlena | Kuźmak Jacek
Bovine immunodeficiency virus (BIV) is found worldwide in cattle under natural conditions. However, the effect of BIV infection on immune functions has not been fully characterised.
Mostrar más [+] Menos [-]Evaluation of a real-time PCR in combination with a cultivation method for the detection of Brucella abortus in organs of infected cattle in southern Italy Texto completo

Brucellosis is a widespread zoonosis of great economic importance for livestock farming in many areas of the world. It is a highly infectious disease which is diagnosed using conventional serological and microbiological methods. The aim of this study was to assess the efficiency of a specific real-time PCR in combination with broth cultivation in detecting Brucella spp. in organs of infected cattle, in order to compare the sensitivity of the two approaches and the time needed in them until a correct diagnosis is made.
Mostrar más [+] Menos [-]Analysis of antimicrobial resistance and genetic correlations of Escherichia coli in dairy cow mastitis Texto completo
2022
Li Ke | Hou Mingyuan | Zhang Lin | Tian Mengyue | Yang Ming | Jia Li | Liang Yanyan | Zou Dongmin | Liu Ruonan | Ma Yuzhong
Escherichia coli is a widespread environmental pathogen frequently causing dairy cow mastitis. This bacterium is particularly capable of acquiring antimicrobial resistance, which can have severe impacts on animal food safety and human health. The objective of the study was to investigate antimicrobial resistance and genetic correlations of E. coli from dairy cow mastitis cases in northern China.
