AI Article Synopsis
- In vitro cultivation and cryopreservation of Babesia bovis and Babesia bigemina are well-established, while Babesia gibsoni's cryopreservation methods are not fully developed.
- This study compared various freezing media for B. gibsoni cryopreservation, including commercial options like CELLBANKER® and STEM-CELLBANKER®, as well as conventional methods using different cryoprotectants.
- The findings suggest that the CELLBANKER® series and other commercial media are more effective for B. gibsoni cryopreservation than existing methods for bovine Babesia and Plasmodium parasites, potentially enhancing the stability of B. gibsoni cultivation.
Article Abstract
In vitro cultivation and cryopreservation under liquid nitrogen have already been reported and established for Babesia bovis and Babesia bigemina parasites. Although the in vitro cultivation methods for Babesia gibsoni have been reported and established, the cryopreservation methods for this parasite have not been established completely. In this paper, we compared several freezing media for the cryopreservation of B. gibsoni parasite. The CELLBANKER® series (1 plus and 2), STEM-CELLBANKER®, and CultureSure® were used for commercial freezing media; 10% dimethyl sulfoxide in 90% fetal bovine serum, 20% polyvinylpyrrolidone in phosphate-buffered saline (established for bovine Babesia parasites), and 28% glycerol supplemented with 3% sorbitol and 0.65% NaCl dissolved in water (established for Plasmodium parasites) were used for conventional media. Our results demonstrated that the CELLBANKER® series (1 plus and 2), STEM-CELLBANKER®, and CultureSure® are effective freezing media for B. gibsoni parasite compared to the cryopreservation methods of bovine Babesia and Plasmodium parasites. Our improved method of cryopreservation would contribute to the stability of the in vitro cultivation of B. gibsoni parasite.

Background: This scoping review provides a baseline summary of the current records of the ticks, fleas, and mites of public health importance that are present in Bangladesh. It summarizes their geographic distributions and reports the levels of their infestation of livestock, pets, wildlife, and humans, and the clinical and epidemiological studies pertinent to these vectors and their pathogens.
Methods: Sixty-one articles were identified in a literature search, including 43 published since 2011.

Article Synopsis
- Current chemical drugs are ineffective for tick control and there are no effective vaccines, leading to the urgent need for new control strategies.
- Small interfering RNAs (siRNAs) have potential to help control parasites, but their effectiveness is limited by challenges in getting them to the RNA-induced silencing complex (RISC).
- This study developed a delivery system using chitosan nanoparticles to successfully transfect siRNAs into parasites, which reduced target gene expression and inhibited parasite growth, opening new avenues for gene therapy and understanding host-parasite interactions.

Article Synopsis
- Tick-borne pathogens (TBPs) in dogs pose a significant global health threat, particularly in developing countries where surveillance is lacking.
- A study involving 230 community dogs in Nepal found that 32.6% were infected with at least one TBP, with common pathogens including Ehrlichia canis and Anaplasma platys.
- The findings suggest that infections in community dogs might pose a risk for transmission to pet dogs and humans, highlighting the need for increased awareness and control measures against these zoonotic parasites.
[Detection of Babesia spp. in ticks and in blood of dogs and red deer in the Czech Republic].

Article Synopsis
- The study aimed to explore the presence of potentially harmful Babesia species in ticks and the blood of dogs and deer across different regions of the Czech Republic, comparing their prevalence with other tick-borne pathogens like Borrelia and Anaplasma.
- From 2014 to 2016, researchers analyzed 675 Ixodes ricinus ticks and blood samples from dogs and deer, finding low positivity rates for Babesia spp., with identified species including Babesia venatorum and Babesia microti, both of which can affect humans.
- The prevalence rates of Babesia in ticks were found to be lower than that of Borrelia spp. (29.3%) and comparable to Rickettsia spp. (1.

is a diverse genus of piroplasms that parasitize the red blood cells of a wide variety of mammals and avian species, including humans. There is a lack of knowledge on the species of carnivores and mesomammals in the eastern United States and the potential impacts of these species on the health of humans and domestic animals. We surveyed 786 wild mammals in the eastern United States by testing blood, spleen, and heart samples with PCR targeting the 18S rRNA region of apicomplexan parasites.
