Summary: In this study, PCV monitoring showed higher sensitivity and specificity for A. marginale parasitemia, performing better compared to other monitoring techniques, especially as the genetic proportion of calves (B. t. taurus) increased. Calves monitored by PCV exhibited better health status and weight gain compared to those monitored by other techniques.

Summary: This study aimed to investigate the molecular detection, genetic diversity, and antigenicity of B. bovis and B. bigemina in cattle in Thailand. The results showed infection rates of 2.58% and 5.80% for B. bovis and B. bigemina, respectively. Phylogenetic analysis revealed multiple clades within Thailand strains, and diversity and entropy analysis provided insights into the genetic variability of the studied genes. Motifs analysis further demonstrated the conservation and distribution of sequences. The findings contribute to a better understanding of the molecular phylogeny, genetic diversity, and antigenicity of B. bovis and B. bigemina Thailand strains.

Summary: This study conducted a surveillance of tick-borne pathogens in cattle in rural areas of several African countries. The prevalence of different pathogens varied among countries and was associated with the distribution of specific vector ticks. Factors such as age, gender, weight, and tick exposure were also found to be related to infections. The findings of this study can provide important insights for monitoring and prevention of tick-borne pathogens in cattle.

Summary: This study investigated the association between BoLA-DRB3 gene and infections of Anaplasma marginale, Babesia bovis, and Babesia bigemina in Crioulo Lageano cattle using PCR-SBT and gene sequencing. The results showed that two alleles were significantly associated with resistance to A. marginale infection, one allele was associated with resistance to B. bovis infection, and none of the alleles were associated with resistance to B. bigemina infection.

Summary: The present study conducted in Beni Hamidene locality, district of Constantine in Northeastern Algeria, estimated the prevalence of haemopathogens in cattle. The results showed that animals were infected by Theileria annulata, Anaplasma marginale, and Babesia bovis, with two co-infection patterns identified. Additionally, a significant difference in T. annulata infection prevalence was found based on age category, highlighting the presence of bovine tropical theileriosis in the region.

Summary: Currently, there are six confirmed species and two genetic variants within the Babesia genus that act as human pathogens. Babesia bovis and Babesia bigemina, which are responsible for bovine babesiosis, have a global distribution, but there are no reports of related human cases. This contribution discusses articles claiming the alleged role of B. bovis and B. bigemina as anthropozoonotic pathogens in Colombia.

Summary: In this study, novel molecular techniques were used to detect and characterize A. marginale in cattle, buffalo, and camel populations in southern Egypt. The prevalence of A. marginale infection was found to be 61% in cattle, 12% in buffaloes, and 6.66% in camels. Phylogenetic analysis provided new data on A. marginale infections in camels. Screening for A. marginale is recommended even in the absence of clinical signs.

Summary: The study evaluated the monitoring of tick fever in a Brazilian dairy farm and found that the current protocols overestimate the occurrence of the disease, leading to overtreatment. Proposing a new monitoring protocol based on rectal temperature and microscopic analysis could result in significant cost savings, rational use of medication, and reduced resistance to antimicrobials.

Summary: This study explores a novel approach using protein secondary structure characteristics and machine learning algorithms to predict exportome membership probabilities. By detecting characteristic differences, the methods presented in this study can accurately classify exportome and non-exportome proteins with an 86-92% accuracy. Therapeutic candidates for laboratory investigation are proposed for several haemoprotozoan species.

Summary: This study evaluated the potential of recombinant N. caninum dense granule protein 6 fused with glutathione-S-transferase (NcGRA6+GST) as a vaccine candidate against neosporosis in a pregnant mouse model. The results showed that NcGRA6+GST partially protected the dams and offspring from N. caninum infection during pregnancy, with higher survival rates and lower parasite burden. This suggests the efficacy of recombinant NcGRA6 for interrupting the vertical transmission of N. caninum in mice by reducing the severity of infections in dams and offspring.

Summary: Equine herpesvirus type-1 (EHV-1) and equine arteritis virus (EAV) are infectious agents that pose serious health risks to horse populations and have a significant impact on the equine industry worldwide. Current vaccines do not provide complete protection against EHV-1 and equine herpes myeloencephalopathy (EHM). Therefore, it is important to have updates and discussions on the nature and characteristics of these viruses in order to prevent outbreaks and limit the spread of these viruses within horse populations.

Summary: Toxoplasmosis, neosporosis, and brucellosis are common diseases causing infectious abortion and economic losses in farm animals. The study in Egypt found the highest seroprevalence rate for T. gondii in sheep and goats, with only antibodies to Brucella spp. associated with recent abortion. These findings could guide the development of more efficient control measures.

Summary: Toxoplasmosis and neosporosis are important protozoan diseases worldwide, and controlling these diseases is currently challenging. Understanding host-parasite interactions and host strategies to combat infections can aid in developing effective control measures, including vaccines. Macrophages and the production of interleukin-12 (IL-12) and interferon gamma (IFN-gamma) play a crucial role in successful vaccine candidates. However, identifying potential vaccine candidates is a time-consuming process.

Summary: The prevalence of antibodies to Neospora caninum and Toxoplasma gondii in raw milk samples from different ruminants and Egyptian governorates was estimated. The study found a seroprevalence of 15.4% for both N. caninum and T. gondii antibodies in bulk milk samples, and 25.7% and 14% for individual milk samples, respectively. The presence of DNA was also detected for both parasites. Pearson correlation analysis showed a strong correlation between bulk and individual samples for T. gondii and a moderately strong correlation for N. caninum.

Summary: This study investigated the prevalence of Sarcocystis spp. in water buffaloes in Elbehera and Kafrelsheikh, Egypt using abattoir inspection, genetic characterization, and histopathology. The total prevalence was 71.0%, with higher prevalence in older buffaloes and females. The esophagus was the most infected organ. Molecular analysis identified S. fusiformis as the recovered species, which is the first genetic characterization in water buffaloes in Elbehera and Kafrelsheikh.

Summary: Published data on tick-borne pathogens in camels worldwide have been collected, providing an overview of their global prevalence and species diversity. Evidence of natural infection of camels with certain tick-borne pathogens is limited, particularly because most of the camels were considered healthy at the time of sampling. More research is needed to understand the role of camels in maintaining and transmitting these pathogens.
