Summary: This study investigated the presence, infection intensity, and seasonality of ticks and tick-borne pathogens on the island of Lesvos in Greece. Results showed that 72.3% of sheep farms during the tick activity season were infected with 9 different tick species, with Rhipicephalus turanicus being the most common. 84.9% of the animals were found to be infected with at least one tick-borne pathogen, with Anaplasma and Theileria being the most common genera. The study highlights the need for a more holistic One Health approach to effectively monitor and control ticks and tick-borne pathogens.

Summary: This study conducted a molecular survey on tick-borne pathogens (TBPs) infecting cattle in the central and southern regions of Malawi. The results showed a high burden of TBPs, with 92.3% of the examined animals infected with at least one TBP. Various species of Anaplasmataceae and piroplasms were detected, highlighting the need for new methods to control ticks and TBPs in order to improve animal health and productivity. The newly developed multiplex PCR assay can be a useful tool, especially in resource-limited settings.

Summary: This study discovered and confirmed a new Jingmen tick virus, named Sichuan tick virus. Four tick samples showed similarity to known JMTV strains and exhibited reassortment signals with other JMTV strains, indicating cross-species transmission and co-infection of segmented flavi-like viruses among multiple tick hosts. Further investigation is required to determine the pathogenicity of Sichuan tick virus to humans and animals, as well as its epidemiological characteristics in nature.

Summary: Ticks are significant vectors of economically important pathogens affecting small ruminants in Africa. This review focuses on the diversity of tick species, tick-borne diseases, and risk factors in Africa. Various species of hard ticks belonging to the genera Hyalomma, Rhipicephalus, Ixodes, and Amblyomma were found infesting small ruminants. Tick-borne protozoal and bacterial pathogens have been reported, as well as non-infectious conditions like tick paralysis and lameness. Integrated control measures are necessary to alleviate the burden of vector-borne diseases in small ruminant production.

Summary: The study found associations between the presence of tick-borne pathogens in ticks feeding on humans and self-reported symptoms. However, due to the subjective nature of such reports and the fact that infection was determined in the ticks and not in the patient samples, further prospective studies utilizing diagnostic modalities should be performed before any clinical outcome can be causally linked to infection with tick-borne pathogens.

Summary: Birds contribute to the multiplication of ticks and pathogens during their breeding season, playing a role in the maintenance of tick-borne diseases. A study in France found that Ixodes ricinus was the most prevalent tick species, while Borrelia burgdorferi sensu lato was the most prevalent pathogen genus in bird-feeding ticks. Certain bird species, such as Turdidae birds, Troglodytes troglodytes, and Anthus trivialis, had a higher prevalence of B. burgdorferi s.l.-infected bird-feeding ticks, indicating their potential role as reservoir hosts for this pathogen during their breeding season.

Summary: Technological and computational advancements in genomics and bioinformatics are being utilized to enhance pathogen discovery and genomic surveillance. The use of single-molecule nucleotide sequence data from ONT sequencing platforms allows for real-time bioinformatic analysis for monitoring various animal-origin zoonotic diseases. The NAS strategy enables immediate mapping of nucleotide molecules to a reference genome, allowing for selective sequencing of DNA from multiple bacterial tick-borne pathogens in wild populations of the blacklegged tick vector, Ixodes scapularis.

Summary: This study aimed to estimate the potential risk of encountering tick-borne pathogens in recreational greenspaces. Tick abundance and pathogen prevalence were higher in natural habitats surrounded by forests, but ticks and pathogens were also found in manicured groundcover. This suggests that even on closely manicured turf, the probability of encountering an infected tick is measurable and substantial if the surrounding landcover is undeveloped.

Summary: Using PCR targeting specific sequences, we clarified the genetic diversity of Trypanosoma spp. in the Kafue ecosystem. The findings suggest that T. vivax is the dominant cause of anemia in the area, with extensive diversity among T. vivax-like lineages. Combining CatL PCR with next generation sequencing proves useful in assessing Trypanosoma spp. diversity, especially for T. vivax and T. vivax-like lineages.

Summary: Primary tracheal small-cell carcinoma is a rare type of cancer that lacks standard treatment, and is often managed using small-cell lung cancer guidelines. We present a case of a patient who developed nodules in the trachea and left main bronchus following surgery for pulmonary large-cell neuroendocrine carcinoma, which were found to be small-cell carcinoma upon biopsy. The patient experienced respiratory failure due to airway stenosis caused by the growing lesion, but showed improvement after receiving first-line chemotherapy and accelerated hyperfractionated radiotherapy.

Summary: This study describes the presentation, clinical signs, parasitemia levels, laboratory findings and treatment of dogs infected with B. negevi. Treatment with imidocarb dipropionate was helpful for recovery from clinical disease but did not facilitate parasite elimination, and it is therefore recommended to treat canine B. negevi infection with the combination of atovaquone and azithromycin.

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.
