Comprehensive epidemiological surveys for Lyme disease have not been conducted for the Bactrian camel in China. In this study, a total of 138 blood specimens collected from Bactrian camels from Zhangye City in Gansu Province and Yili and Aksu in Xinjiang Province, China, were examined for the presence of Borrelia spp. Species-specificity nested PCR based on the 5S-23S rRNA, OspA, flaB and 16S rRNA genes revealed that the total positive rate of Borrelia spp. was 3.6% (5/138, 95% CI = 0.2-17.9). These results were confirmed by sequence analysis of the positive PCR products or positive colonies. This is the first report of Borrelia pathogens in camels in China. Two Borrelia species that cause Lyme disease and one that causes relapsing fever were identified in the camel blood samples by sequencing. The findings of this study indicate that the Bactrian camel may serve as a potential natural host of Lyme disease and/or relapsing fever in China.

The current study aimed to determine the impacts of hCG injection on the reproductive performance and hormonal profile of senile camels. Ten adult senile camels were classified into two groups: control males (n = 5) and treated males (n = 5; received hCG) once/week. Testicular morphology and echotexture [testicular volume (TV), testicular echogenicity (TE), and pixel heterogeneity (PH)] were measured.

Rift Valley Fever (RVF) remains a significant public health and economic concern in Niger, particularly in the Tahoua region. This study aimed to update seroprevalence estimates of Rift Valley Fever Virus (RVFV) and identify high-risk areas and animal populations. A cross-sectional survey was conducted between January and May 2024, during which 615 domestic ruminants (cattle, sheep, goats, and camels) were sampled and tested for RVFV-specific antibodies using a competitive enzyme-linked immunosorbent assay (cELISA).

Introduction: MiR-144-5p is differentially expressed in plasma exosomes from Bactrian camels of varying body sizes, with GO and KEGG analyses indicating that its target genes play crucial roles in lipid metabolism. PGC-1α, confirmed as a key target through RNA pull-down and dual-luciferase reporter assays, is a significant regulator of this process. This study aims to investigate the impact of miR-144-5p on lipid metabolism in a mouse model of high-fat diet (HFD)-induced obesity to elucidate the mechanistic pathways involved.

SARS-CoV and MERS-CoV are two coronaviruses that have received significant attention due to their high pathogenicity and mortality rates in human populations. In this study, we compared their evolutionary dynamics to provide a One Health perspective on their differences in terms of the results of disease control. The phylogenetic network of SARS-CoVs showed that human isolates gathered into a "super-spreader" cluster and were distinct from civet isolates.

Hyalomma dromedarii, a predominant camel tick species in the Arabian Peninsula, plays a significant role in pathogen transmission, yet its sex-specific microbiome composition remains poorly understood. This study analyzed the bacterial communities of male and female H. dromedarii ticks collected from camels across three locations in the United Arab Emirates: Al Khazna, Al Ja'ae, and Al Jabeeb.
