Summary: The study aimed to establish the prevalence, epidemiology, and molecular characterization of major haemoprotozoons and rickettsia of cattle in the Jammu region, North India. The prevalence based on microscopy was 12.9%, while PCR recorded 30.22% animals positive for haemoparasitic infections. Hematological alterations in diseased animals affected productivity. Genetic characterization of Babesia bigemina, Anaplasma marginale, and Theileria annulata provided representative data of the isolates circulating in the region.

Summary: This study conducted a cross-sectional investigation on cattle in the Karamoja Region of northeastern Uganda, identifying 12 different tick species, some of which were previously unreported. Parasites that transmit diseases and uncommon pathogens harmful to cattle were detected in the vectors. The gathered information serves as an indicator for estimating potential disease transmission risks among cattle populations and to humans, aiding in disease control strategies.

Summary: Theileria, Babesia, and Anaplasma are prevalent tick-borne pathogens worldwide, especially in tropical and subtropical regions. In Egypt, there is a high prevalence of TBPs, with significantly higher rates in LSD-positive animals compared to FMD-positive animals. Crossbreed cattle showed higher rates of Babesia and Theileria infections, while native cattle had higher rates of Anaplasma infections and co-infections with Babesia-Anaplasma and Theileria-Anaplasma. The intensity of parasitic infection was significantly higher in positive groups for LSD and FMD compared to negative groups.

Summary: Ticks are common vectors of various pathogenic agents affecting cattle production and human health in Angola. The rapid growth of urban population has increased the risk of pathogen transmission between animals and humans. Lack of health infrastructures in rural regions hampers swift diagnosis and treatment, resulting in a potentially severe impact on health.

Summary: A structural variant (SV1) in the agouti signaling protein gene (ASIP) has been found to be strongly associated with hair coat darkness in specific regions of zebu cattle from the Nellore breed. Analysis of whole-genome sequences of zebu and taurine cattle revealed that ASIP-SV1 is commonly found in 45.9% of zebu cattle and 6.3% of taurine cattle, with the taurine cattle showing zebu introgression or being from crossbreeding. This study provides evidence of the widespread presence of ASIP-SV1 in both zebu populations and taurine cattle with zebu admixture.

Summary: B. bovis is a causal agent of bovine babesiosis and sequence variation between B. bovis parasites in southern Africa was determined by amplifying and sequencing the msa-2b and 18S rRNA genes. The TaqMan qPCR assay was optimized for the detection of B. bovis in field samples. The optimized qPCR assay showed higher detection rate compared to the reverse line blot assay and previously published qPCR assay.

Summary: Ticks in Africa remain a major obstacle in the livestock industry due to tick-borne pathogens. This study conducted a systematic review and meta-analysis to examine the distribution and prevalence of these pathogens in African ticks. The highest prevalence was found for Rickettsia spp., R. africae, R. conorii, A. marginale, E. ruminantium, and E. canis. The prevalence of C. burnetii was low, but higher for Coxiella spp. and Coxiella-like endosymbionts. The study also identified the effect of tick genera, tick species, country, and other variables on the epidemiology of these pathogens in ticks.

Summary: This study investigated the effects of feeding flaxseed and plant polyphenol extracts on fatty acid content, oxidative stability, and lipid health indices in eggs. The results showed that the inclusion of flaxseed and moderate doses of plant polyphenol extracts significantly increased the content of n-3 polyunsaturated fatty acids in eggs and improved lipid health indices.

Summary: This study analyzed the whole genome sequences of 151 samples from 14 Ethiopian indigenous cattle populations to assess genomic diversity, differentiation, and selection signatures. The results revealed high genomic differentiation between Ethiopian and non-Ethiopian cattle populations, as well as low differentiation and inbreeding within Ethiopian cattle populations. Furthermore, candidate genes associated with various biological functions and molecular pathways were identified in Ethiopian cattle.

Summary: Rabies still claims the lives of approximately 59,000 people annually, mostly due to dog bites. The Zero by 30 initiative, aiming to end human deaths from dog-mediated rabies by 2030, provides a framework for achieving this through a One Health approach. In 2020, the United Against Rabies Forum was established to further this global goal. This paper reviews the objectives, governance, activities, and achievements of the Forum, and discusses future plans and priority areas.

Summary: Bovine brucellosis is a neglected zoonotic disease in Tanzania. A cross-sectional study was conducted to determine the prevalence and risk factors of brucellosis in smallholder dairy cattle. The results showed a seroprevalence of 2.39%, with the highest percentage in the Njombe Region. Risk factors identified were the presence of goats and a history of abortion. Education of farmers and a One Health approach are recommended to control the disease.

Summary: The review summarizes the research on genomic regions under positive selection in indigenous African cattle breeds, highlighting candidate genes and genome regions associated with adaptation to extreme environments and environmental challenges such as heat stress, infectious diseases, and high altitude. The review also emphasizes the importance of identifying candidate causative variants controlling these traits and provides guidance for future targeted genome studies. The highest numbers of candidate regions are found on BTA3, BTA5, and BTA7, overlapping with genes involved in various biological functions and pathways.
