Background Dermatophytosis is a fungal infection that can be zoonotic, with transmission occurring in both directions between humans and companion animals, particularly in settings involving close contact. This study aimed to determine the prevalence and identify the causative agents of dermatophytosis in dogs and cats using conventional and molecular diagnostic methods. A total of 150 animals with dermatological lesions were sampled, including 105 cats and 45 dogs from both household and shelter environments. This cross-sectional study employed direct microscopy and fungal culture as the initial diagnostic methods. PCR targeting the CHS1 gene was subsequently performed on fungal isolates obtained from 38 culture-positive samples, followed by species-specific amplification to identify Microsporum canis and Trichophyton rubrum . For molecular identification, DNA was extracted from pure cultures derived from hair, skin scrapings, and nail specimens. ITS region sequencing was also performed on two of the PCR-confirmed T. rubrum isolates. Prevalence was compared across animal species, age groups and living environments. Results Dermatophytes were detected in 25.3% (38/150) of samples. In cats, only M. canis 76% (19/25) was identified. In dogs, both M. canis (5/13) and T. rubrum (2/13) were found. This represents the first report of T. rubrum in a dog in Türkiye, with ITS sequencing confirming > 99% identity to reference strains. Infection rates were significantly higher in animals under one year of age (p = 0.0097 ), while no statistically significant difference was observed between dogs and cats (p = 0.529). PCR and sequencing provided rapid and accurate identification. Conclusions Dermatophyte infections are more prevalent among juvenile animals and pose a growing zoonotic threat. Molecular diagnostics improve early detection and control strategies. These findings highlight the need for routine surveillance and reflect the critical importance of the One Health approach, which integrates human, animal, and environmental health to prevent and manage zoonotic disease transmission.

Background Brucellosis is a zoonotic disease whose causative agent, Brucella spp., is endemic in many countries of the Mediterranean basin, including Greece. Although the occurrence of brucellosis must be reported to the authorities, it is believed that the disease is under-reported in Greece, and knowledge about the genomic diversity of brucellae is lacking. Methods Thus, 44 Brucella isolates, primarily B. melitensis , collected between 1999 and 2009 from humans and small ruminants in Greece were subjected to whole genome sequencing using short-read technology. The raw reads and assembled genomes were used for in silico genotyping based on single nucleotide substitutions and alleles. Further, specific genomic regions encoding putative virulence genes were screened for characteristic nucleotide changes, which arose in different genotype lineages. Results In silico genotyping revealed that the isolates belonged to three of the known sublineages of the East Mediterranean genotype. In addition, a novel subgenotype was identified that was basal to the other East Mediterranean sublineages, comprising two Greek strains. The majority of the isolates can be assumed to be of endemic origin, as they were clustered with strains from the Western Balkans or Turkey, whereas one strain of human origin could be associated with travel to another endemic region, e.g. Portugal. Further, nucleotide substitutions in the housekeeping gene rpoB and virulence-associated genes were detected, which were characteristic of the different subgenotypes. One of the isolates originating from an aborted bovine foetus was identified as B. abortus vaccine strain RB51. Conclusion The results demonstrate the existence of several distinct persistent Brucella sp. foci in Greece. To detect these and for tracing infection chains, extensive sampling initiatives are required.

species are known to be very important in human and domestic animal health. species commonly cause severe systemic and skin infections, as well as allergic lung diseases. With the development of PCR techniques, these methods are used to identify and diagnose fungi. DNA extraction from species is difficult because the fungal cell wall structure is very durable and complex. Fungal DNA extraction methods containing proteinase K and liquid nitrogen are widely used to break down the cell wall. However, these methods cause DNA loss during the extraction in species. In this study, on the contrary, the commonly used DNA extraction by means of ammonium hydroxide, which is generally used to break down chitin in DNA extraction of ticks and plants, is used. The efficiency of the cell wall lysis method from with ammonium hydroxide was compared with methods containing proteinase K and liquid nitrogen. For this purpose, DNA extraction of was tried using three different methods. As a result, the cell wall of was lysed using ammonium hydroxide in this study. The obtained DNA’s quality, concentration, and PCR performance were sufficient. This method has been evaluated as a faster, more straightforward, and more economical alternative.

ABSTRACT Background Bordetella bronchiseptica is an essential bacterial pathogen characterized by chronic respiratory disease in dogs known as Kennel cough. The presence of causative antibodies in animals can also be detected by lipopolysaccharide antigen‐based enzyme linked immunosorbent assay (ELISA). In recent years, it has been determined that there is a significant relationship between acute phase proteins and diseases, and disease follow‐up can be done within the framework of this relationship. Methods In this study, blood sera from 150 dogs in an animal shelter in Van province were evaluated for B. bronchiseptica by the homemade ELISA method, and their correlations with serum amyloid A (SAA) were investigated. Blood serum samples were analysed for antibodies against B. bronchiseptica using a homemade ELISA method. Positive animals were also molecularly confirmed using nasal swabs by PCR. A commercial ELISA kit determined SAA levels in blood sera. Results Eighteen (12%) of the analysed blood serum samples were found positive by the homemade ELISA method. SAA concentrations in the positive blood sera were elevated from 12.7 to ≤38.98 mg/L. SAA concentrations in blood sera serologically positive for B. bronchiseptica were statistically significant. Conclusions In this study, in which the relationship between SAA concentration and B. bronchiseptica was investigated for the first time in Turkey, it was concluded that SAA concentration analysis may help diagnose and monitor the disease. In addition, the presence and prevalence of this critical and zoonotic agent causing chronic respiratory tract disease in dogs in Van province was revealed for the first time in this study. A study in Van, Turkey examined Bordetella bronchiseptica in shelter dogs using ELISA and PCR. Overall, 12% of blood samples tested positive. Serum amyloid A (SAA) levels were significantly elevated in positive cases, suggesting SAA could be a useful diagnostic marker for this chronic respiratory disease‐causing bacterial pathogen.

The global trend of in vitro embryo systems, particularly the in vitro fertilization (IVF) culture system, is gaining momentum. Despite the strict standards followed in in-vitro embryo procedures, microbiological contamination is occasional, and the relevant literature is scarce. In this study, for the first time, IVF culture dishes with microbial contamination and resistance genes of isolates were evaluated in veterinary medicine. Samples were microscopically taken from IVF tissue cultures suspected of bacterial or fungal contamination and sent to the microbiology laboratory for further examination. The total contamination rate was 11.1% in IVF cultures where cell division did has stopped or turbidity occurred. Identification of contaminant microorganisms showed that infections were mainly caused by 9.5% and spp. 1.58%. A set containing multiplex antibiotic primers was used during the IVF protocol to determine antibiotic resistance genes. All isolates were resistant to penicillin used in the Kirby-Bauer, and 16% was resistant to streptomycin. This study is the first systematic evaluation of microbial contamination of bovine IVF culture vessels in veterinary medicine. IVF culture should be evaluated in more detail to learn more about the source of the microorganism and to develop adequate measures to prevent microbial contamination.

The aim of this study was to investigate Q fever seroprevalence in sheep and goats in the Marmara region. Q fever is a zoonotic disease caused by . In ruminants, the disease causes reproductive disorders, premature births and stillbirths. Blood samples of sheep and goats were collected from the Marmara region of Turkey and a commercial ELISA was used for detection of specific antibodies to . A total of 832 samples (627 from sheep and 205 from goats) obtained from 126 herds located in 110 villages in 63 municipalities across all 11 provinces were utilised. Total seroprevalence was found to be 13.22%, while the proportion of seropositive herds was determined to be over threefold higher at 42.85%. The seroprevalence for sheep was found to be 14.19%, and for goats 10.24%. The herd seropositivity rate for sheep of 46.31% and for goats of 32.25% were also over threefold higher than the species-level seroprevalences. The provincial seroprevalence varied between 1.38% and 21.79%. This study confirms the presence of in sheep and goat herds in the Marmara region and provides original seroprevalence data in hitherto uninvestigated provinces. The data gathered are beneficial for evaluation and elaboration of the seroprevalence of Q fever in sheep and goats in the Marmara region. Surveillance studies should be maintained, particularly in provinces with high seropositivity rates.

Brucellosis is an important bacterial zoonosis of domestic and wildlife species. This disease has a significant public health concern and is characterized by reproductive failure resulting in economic losses in the livestock industry. Among thirteen known species, B. abortus, B. melitensis, B. suis, and B. canis are human pathogens. Brucellosis has been extensively investigated in humans and domestic animals. However, the situation in wildlife is still not completely reported and studied. Therefore, a systematic literature search and screening were done to clarify the situation of brucellosis in wildlife in Europe. Sixty-five articles from a total of 13,424 reports published between 1991 and 2021 were selected, applying defined inclusion criteria. Wild boars and brown hares were the most often studied terrestrial wildlife species, whereas seals and porpoises were the most often investigated marine wildlife. Poland, Croatia, and Belgium showed the highest seroprevalences of wild boars caused by B. suis biovar 2. In marine wildlife, brucellosis was mainly caused by B. ceti and B. pinnipedialis. Most samples were from carcasses. Thus, sera could not be collected. It is worrisome that B.abortus and B. melitensis were reported from both terrestrial and marine wild animals, posing a zoonotic threat to people exposed to wild animals. Currently, there is no approved vaccine available for wild animals. The main challenges are the development of specific diagnostics and their validation for use in wildlife.

Brucellosis is a disease caused by the Brucella (B.) species. It is a zoonotic disease that affects farm animals and causes economic losses in many countries worldwide. Brucella has the ability to persist in the environment and infect the host at low doses. Thus, it is more important to trace brucellosis outbreaks, identify their sources of infection, and interrupt their transmission. Some countries already have initial data, but most of these data are based on a Multiple-Locus Variable-Number Tandem-Repeat Analysis (MLVA), which is completely unsuitable for studying the Brucella genome. Since brucellosis is an endemic disease in Turkey, this study aimed to examine the genome of Turkish Brucella isolates collected between 2018 and 2020, except for one isolate, which was from 2012. A total of 28 strains of B. melitensis (n = 15) and B. abortus (n = 13) were analyzed using a core-genome single-nucleotide polymorphism (cgSNP) analysis. A potential connection between the Turkish isolates and entries from Sweden, Israel, Syria, Austria, and India for B. melitensis was detected. For B. abortus, there may be potential associations with entries from China. This explains the tight ties found between Brucella strains from neighboring countries and isolates from Turkey. Therefore, it is recommended that strict measures be taken and the possible effects of uncontrolled animal introduction are emphasized.

There are more than 207 types of Human Papillomavirus (HPV), most of which do not cause symptoms, lesions, or warts, and cause more than 600,000 cases of cancer annually. Purpose:This study was planned to elucidate the relationship between individuals' HPV knowledge, attitudes towards the HPV vaccine, and vaccine hesitancy. The research was conducted with 1011 people using a descriptive and correlational research design. Data collection tools included socio-demographic information survey, HPV Knowledge Scale, Carolina HPV Vaccination Attitudes Scale, and Vaccine Hesitancy Scale. The data was analyzed using the SPSS 26.0 package program. The average score was 11.68±7.23 on the HPV Knowledge Scale, 30.76±7.31 on the HPV Vaccine Attitude Scale, and 27.90±11.10 on the Vaccine Hesitancy Scale. While there was a very weak negative relationship between the participants HPV knowledge and HPV Vaccine Attitude scores, a weak positive relationship was found with vaccine hesitancy. A weak positive relationship was also detected between vaccine attitude and vaccine hesitancy (p<0.05). According to the regression model created in the study, HPV vaccination attitude was explained by the HPV Knowledge Scale and vaccine hesitancy at a rate of 22.5%. In line with the results, healthcare professionals need to raise awareness in the society and increase vaccination rates. Il existe plus de 207 types de papillomavirus humain (HPV), dont la plupart ne causent pas de symptômes, de lésions ou de verrues, mais entraînent plus de 600 000 cas de cancer chaque année. Objectif : Cette étude a été planifiée pour élucider la relation entre les connaissances des individus sur le HPV, leurs attitudes envers le vaccin contre le HPV et l'hésitation vaccinale. La recherche a été menée auprès de 1011 personnes en utilisant un plan de recherche descriptif et corrélationnel. Les outils de collecte de données comprenaient un sondage d'informations sociodémographiques, l'Échelle de Connaissances sur le HPV, l'Échelle des Attitudes envers la Vaccination contre le HPV de la Caroline et l'Échelle d'Hésitation Vaccinale. Les données ont été analysées à l'aide du programme SPSS 26.0. Le score moyen était de 11,68 ± 7,23 à l'Échelle de Connaissances sur le HPV, de 30,76 ± 7,31 à l'Échelle des Attitudes envers la Vaccination contre le HPV, et de 27,90 ± 11,10 à l'Échelle d'Hésitation Vaccinale. Bien qu'il y ait eu une très faible relation négative entre les connaissances des participants sur le HPV et les scores d'attitude envers le vaccin contre le HPV, une faible relation positive a été trouvée avec l'hésitation vaccinale. Une faible relation positive a également été détectée entre l'attitude envers la vaccination et l'hésitation vaccinale (p<0,05). Selon le modèle de régression créé dans l'étude, l'attitude envers la vaccination contre le HPV était expliquée par l'Échelle de Connaissances sur le HPV et l'hésitation vaccinale à un taux de 22,5 %. Conformément aux résultats, les professionnels de la santé doivent sensibiliser la société et augmenter les taux de vaccination.
