Purpose: The objectives of the present study are to determine the molecular prevalence of Leishmania spp. in the owned domestic cats in the Black Sea Region of Türkiye and analyze the associated risk factors in FeL., Methods: Conjunctival swabs (CS), blood, demographic, and clinical data were collected from 150 owned cats brought to the Veterinary Teaching Hospital during 2020-2022. Leishmania kinetoplast DNA (kDNA) from CS was screened by TaqMan Real-Time PCR (qPCR) with the genus-specific primers and a probe., Results: All qPCR positive products were also amplified and sequenced to identify Leishmania species by ITS1 primers. Molecular prevalence of L. infantum found as 12.6% (19/150) in the observed cats in the Black Sea Region of Türkiye. There was a significant difference (p < 0.05) between neutered and intact cats with regarding to L. infantum positivity. Intact cats found to be 0.368 times more prone to be L. infantum-positive (L+). Dermatological lesions were found the most common (26.3%) problems in the L + cats. The median leucocyte count was the only parameter that was found statistically (p < 0.05) lower in the L + group (6.60) than the negative group (L-) (8.96), when comparing the WBC, NEU/LYM, MONO/LYM, EOS/LYM and PLT/LYM values., Conclusion: This study presented the molecular occurrence of FeL in the Black Sea Region of Türkiye for the first time indicating that the carrier status of the cats makes them alternative reservoirs for possible zoonotic transmission of L. infantum in this zone., (© 2024.

Purpose: Canine ehrlichiosis is an important tick-borne disease of dogs worldwide. In the present study, we aimed to determine the serum total antioxidant capacity (TAC), malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase, (SOD), glutathione peroxidase (GSH-Px), adenosine deaminase (ADA) activity and serum protein profiles in dogs affected with naturally acquired ehrlichiosis., Methods: The animal materials had been consisted of ten dogs naturally infected with Ehrlichia canis, and ten controls negative for Ehrlichia canis. TAC, MDA, NO, SOD, GSH-Px, ADA activity and TP, ALB, GLOB levels were measured in sera of the animals. The serum protein concentrations were measured by autoanalyzer. The electrophoretic profiles of serum total protein were determined by native polyacrylamide gel electrophoresis (Native-PAGE)., Results: In dogs with ehrlichiosis, decreased TAC (P < 0.05) and GSH-Px (P > 0.05) levels were determined. However, NO (P > 0.05), SOD (P < 0.05), ADA (P > 0.05), MDA (P > 0.05), TP (P < 0.05) and GLO (P < 0.05) levels were found as increased in the Ehrlichia positive dogs. ALB levels were decreased without a statistical significance (P > 0.05). ALB, α1 and β2 globulin strip densities were found as decreased in native-PAGE, while β1 and γ globulin strip densities were significantly increased in the E. canis positive group when compared to the control., Conclusion: It was determined that the oxidative stress decreased high antioxidant activity in dogs naturally infected with E. canis, and consequently, pro-oxidant and antioxidant defense and serum protein profiles were affected. It was thought that antioxidant supplementation could be beneficial to the treatment of the disease., (© 2021. Witold Stefański Institute of Parasitology, Polish Academy of Sciences.)

Objective: This preliminary study was conducted to reveal that the molecular identity of Encephalitozoon spp. and Enterocytozoon bieneusi in indoor domestic cats' fecal samples from Turkey was screened using the PCR., Materials and Methods: Nested PCR was performed using MSP and EBITS primers. All of the amplification products were sequenced to identify the microsporidia species., Results: Four (5.5%) and three (4.1%) genomic DNA isolates of the fecal samples from 72 indoor domestic cats showed amplification of the ITS regions of E. bieneusi and Encephalitozoon spp., respectively. Two different genotypes, D and IV, of E. bieneusi were determined in two cats each based on the ITS sequence analyses. Moreover, Encephalitozoon spp. sequence analyses revealed three isolates belonging to E. intestinalis., Conclusions: This preliminary study has provided the first molecular data on the zoonotic genotypes of E. bieneusi and E. intestinalis in cats in Turkey. Furthermore, E. bieneusi genotype IV (accession number MG727664) was submitted to GenBank for the first time in the Western Palearctic Region as hosted by a domestic cat. Additionally, E. intestinalis (accession number MG570080) was also submitted to GenBank as a valid ITS sequence for the first time as hosted by a domestic cat worldwide.
