Bovine viral diarrhea virus (BVDV) is the causative agent of bovine viral diarrhea. It can infect cattle, sheep, pigs, and other animals, causing diarrhea, miscarriage, and stillbirth, among other symptoms, and it can result in huge economic losses to animal husbandry. There are reports on BVDV infection rates in sheep and goat herds from all over the world and this meta-analysis aimed to evaluate the prevalence of and risk factors for BVDV in sheep and goats.

Bluetongue is characterized by fever, leukopenia, and severe catarrhal inflammation of the oral and gastrointestinal mucosa. The present study aimed to evaluate and analyze the prevalence of bluetongue and its associated risk factors in sheep and goats in China.

- Eimeria spp. causes coccidiosis, a disease that significantly weakens livestock and can result in their death, leading to major economic losses, particularly in the cattle industry.
- This review is the first systematic analysis of how prevalent Eimeria infections are in cattle across mainland China, highlighting data from 46 articles that revealed prevalence rates varying from 4.6% to 87.5%.
- The study found that the infection rate has decreased over the years, from 57.9% before 2000 to 25.0% after 2015, but remains a concern, suggesting that prevention strategies should prioritize better detection in calves within intensive farming systems.
Brucellosis is an important zoonotic disease caused by spp. Brucellosis is widely distributed in more than 160 or 170 countries around the world, where it poses a huge threat to animal husbandry and human health. About 150 million head of water buffalo, distributed across more than 40 countries worldwide, are kept for the purposes of service, milk, and meat.

Article Synopsis
- A systematic review and meta-analysis were conducted to assess the prevalence of a harmful gram-negative microorganism in swine in China, gathering data from 72 publications between 1985 and 2020.
- The overall prevalence was found to be 22.48%, with a notable increase in southern China (30.97%) compared to northern China (10.79%), and the highest prevalence recorded in Hubei province (36.23%).
- The study suggests improved detection methods in breeding pigs, particularly those with reproductive disorders, and recommends controlling environmental factors in large-scale farms to mitigate future infections.
Article Synopsis
- Bovine leukemia is a contagious tumor disease in cattle caused by the bovine leukemia virus (BLV), which is prevalent in many regions and poses potential risks to animal and human health.
- A meta-analysis of 35 studies in China from 1983-2019 found a 10% prevalence rate of BLV among 34,954 tested cattle, with significant differences based on factors like sampling year, age, and detection methods.
- The research suggests a higher prevalence in cattle sampled before 1985 and aged 3-5 years, recommending increased testing and the use of methods like PCR to better control and prevent the disease.
Porcine circovirus type 2 (PCV2) causes infectious diseases in pigs leading to considerable economic losses in the pig industry. To prevent and control PCV2 infections, is important to understand the prevalence and geographical distribution of the virus. We performed the first systematic review and meta-analysis to estimate the prevalence of PCV2 in China.

Methods: Thirty-two antiseptic femurs were randomly divided into four groups. After internal fixation had been implanted, different types of subtrochanteric fracture models were produced and each tested under vertical, torsional and vertical damage loads.
Objective: To compare biomechanical effect of the closed fracture model with intramedullary nail fixation and the open fracture model with plate fixation in rats.
Methods: Forty 8-week-old Spragu-Dawley male rats were divided into two groups randomly. Left femoral shaft closed fractures model was created in 20 rats, and treated with intramedullary nail.
Study Design: Methodological systematic review.
Objective: To identify the risk factors for new vertebral compression fractures (VCFs) in patients after percutaneous vertebroplasty (PVP) and to grade the evidence according to the quality of included studies.
Summary Of Background Data: PVP is an effective procedure for the treatment of VCFs.
Objective: To identify the independent risk factors, based on available evidence in the literature, for patients developing surgical site infections (SSI) after spinal surgery.
Methods: Non-interventional studies evaluating the independent risk factors for patients developing SSI following spinal surgery were searched in Medline, Embase, Sciencedirect and OVID. The quality of the included studies was assessed by a modified quality assessment tool that had been previously designed for observational studies.
