Clinical Cases of Tick-Borne Diseases in Dogs During the Autumn-Winter Season in Poland.

Pathogens

December 2024

Department of Veterinary Prevention and Feed Hygiene, Faculty of Veterinary Medicine, University of Warmia and Mazury in Olsztyn, 10-719 Olsztyn, Poland.

Tick-borne diseases (TBDs) pose a growing threat to companion animals, especially dogs, due to the increasing abundance of tick populations in Europe, driven by climate change, urbanization, and the mobility of humans and animals. This study aimed to assess the prevalence of tick-borne pathogens in clinically ill dogs suspected of having developed TBDs during the autumn-winter season, as well as to detect pathogens in ticks collected during the same period in the Warmian-Masurian Voivodeship in Poland. A total of 30 dogs with clinical symptoms of babesiosis and 45 ticks from dogs were acquired for this study.

Department of Hematology, Rheumatology and Infectious Disease, Faculty of Life Sciences, Kumamoto University, Kumamoto, Japan.

Human T-cell leukemia virus type 1 (HTLV-1) causes adult T-cell leukemia (ATL) and HTLV-1-associated myelopathy (HAM) after a long latent period in a fraction of infected individuals. These HTLV-1-infected cells typically have phenotypes similar to that of CD4+T cells, but the cell status is not well understood. To extract the inherent information of HTLV-1-infected CD4+ cells, we integratively analyzed the ATAC-seq and RNA-seq data of the infected cells.

Legume content (LC) in grass-legume mixtures is important for assessing forage quality and optimizing fertilizer application in meadow fields. This study focuses on differences in LC measurements obtained from unmanned aerial vehicle (UAV) images and ground surveys based on dry matter assessments in seven meadow fields in Hokkaido, Japan. We propose a UAV-based LC (LC) estimation and mapping method using a land cover map from a simple linear iterative clustering (SLIC) algorithm and a random forest (RF) classifier.

To clarify the cause of graded distribution of sucrose in apple fruit flesh, a quarter cut of young apple fruit was cultured for 72 h on agar-solidified MS medium supplemented with 0.5 M [1-C]sorbitol, with the longitudinal or horizontal cut face being attached with the medium, and distribution of C-labelled sucrose in a specimen obtained by slicing the fruit along with the cut face was visualized utilizing MALDI-TOF MSI. Heat map images on the distribution of the peaks of sorbitol containing C-atom indicated that external [1-C]sorbitol had penetrated evenly into the tissue.

This study focused on the synthesis, structural validation, and evaluation of the antiplasmodial efficacy of brachangobinan A (BA) and its enantiomers, (+)-BA and (-)-BA, as potential antimalarial agents. BA, (+)-BA, and (-)-BA were synthesized through chemical processes and validated via advanced spectroscopic techniques. In vitro studies were conducted to assess their efficacy against Plasmodium falciparum strains 3D7 and K1 by determining their half maximal inhibitory concentration (IC) values, cytotoxicity profiles, and selectivity indices.

Most members of the genus Orthonairovirus, represented by Crimean-Congo hemorrhagic fever virus and Nairobi sheep disease virus, are tick-borne, and some have become a public health concern in recent years. Here, we report the isolation and genetic and biological characterization of a new orthonairovirus, designated as "Iwanai Valley virus" (IWVV), from Ixodes ovatus ticks in Hokkaido, Japan. The amino acid sequence of the viral nucleoprotein (NP) was found to be 34-45% identical to those of known orthonairoviruses.

Malaria remains a major public health threat in Burkina Faso, as in most sub-Saharan Africa countries. Malaria control relies mainly on long-lasting insecticide-treated nets (LLINs) and indoor residual spraying. In Burkina Faso, an escalating of insecticide resistance has been observed over the last decades.

Early diagnosis of canine dilated cardiomyopathy (DCM) is complicated by the presence of a prolonged asymptomatic phase, for which a comprehensive evaluation of myocardial function is essential. This pilot study was conducted to evaluate the myocardial function in dogs with DCM using two-dimensional speckle tracking echocardiography (2D-STE). Nine client-owned Retrievers with DCM and twelve client-owned clinically normal Retrievers were comparatively evaluated using standard echocardiography and 2D-STE.

From October 2020 to February 2021, a total of 95 retail chicken meat products from 39 retail meat shops in Tokyo Metropolis and Kanagawa Prefecture, Japan, were collected and examined for the prevalence of Salmonella to assess public health implications. If a sample tested positive for Salmonella, a quantitative analysis was performed using the three-tube most probable number (MPN) method. Of 95 retail chicken meat products, Salmonella was isolated from 30 samples (31.

The energy status of dams during the early stages of gestation may affect ovarian reserves. It was hypothesized that greater milk yield and composition during the early stages of gestation may suppress the number of primordial follicles in the fetuses of dairy cattle. This study aimed to evaluate the anti-Müllerian hormone (AMH), used as an indicator of ovarian reserves, in female Holstein calves immediately after birth.

Cryptosporidiosis is a major cause of diarrhea and is associated with high morbidity in calves. Changes in the gut microbiota exacerbate diarrhea caused by infection in neonatal and weaned calves. However, information on the gut microbiota of neonatal calves with infection is scarce, and research into the microbiome of calves is essential for developing preventive and therapeutic interventions.

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.

Heat stress (HS) reduces dry-matter intake and causes negative energy balance (EB) in Holstein cattle, with consequent deterioration in milk production and wellness. Therefore, the effects of HS can be detected more directly from imbalances in EB than from the consequent changes in production or health traits. EB can be monitored by metabolism-related traits such as predicted EB (PEB), the fat-to-protein ratio (FPR), or β-hydroxybutyrate (BHB) in milk.

Artificial insemination (AI) in cattle involves introducing frozen-thawed sperm, a minimal amount of seminal plasma, and a significant volume of semen extender (SE) into the uterus. Previous studies have demonstrated that sperm interacts with bovine endometrial epithelia via TLR 2/1, triggering a weak inflammatory response to clear the endometrium. This study investigated the impact of the major component of the insemination dose, egg yolk-based SE, on the uterine immune response in vitro.

Horseflies are pests that cause discomfort from blood-sucking and disease transmission, and economic losses in the equine industry. This study evaluated the efficacy of horsecloth impregnated with icaridin in reducing horsefly attacks and deterring horseflies. Repellent activities were evaluated under three conditions: treatment 1 (no horsecloth), 2 (horsecloth without icaridin), and 3 (horsecloth impregnated with icaridin), using three native Hokkaido horses (Dosanko) and three mixed-breed horses (Dosanko and Haflinger) in July 2023 at a riding horse club in Hokkaido, Japan.
