Abstract Background Toxoplasmosis, caused by the protozoan parasite Toxoplasma gondii, is often linked with reproductive disorders in humans and animals. Despite this, its presence in animals in the Federation of Bosnia and Herzegovina (FB&H) remains undocumented. Objectives This study aimed to investigate the seroprevalence of T. gondii infection among domestic pigs in FB&H, assess associated risk factors for parasite transmission and provide insights into optimal management and biosafety practices for the pig industry. Methods A two‐phase random sampling approach was employed to select 87 pig farms across 10 administrative regions in FB&H. A total of 437 pigs were sampled and tested for anti‐T. gondii antibodies using an indirect ELISA kit. Epidemiological data on potential risk factors were collected through a standardised questionnaire and analysed using logistic regression models. Results The animal‐level seroprevalence was found to be 13.3% (95% CI = 10.4–16.8), with 44.8% of farms testing positive for T. gondii (95% CI: 34.8–55.3). Identified risk factors included exposure to cats, repeated occurrences of abortions within a single breeding season, swill feeding, type of housing, and type of operation. The robust association observed between recurrent abortions and Toxoplasma seropositivity indicates a significantly greater potential involvement of T. gondii in reproductive disorders among pigs in FB&H than previously acknowledged. Conclusions This study provides the first report on T. gondii infection in animals in FB&H, highlighting the need for further research to explore its presence in other meat animals and meat products consumed in the region. The findings underscore the importance of biosafety measures in mitigating T. gondii transmission and call for enhanced surveillance and management strategies in FB&H's pig industry.

Introduction The veterinary profession is facing various challenges in the 21st century, such as livestock production intensification, shifting distribution of infectious diseases, growing focus on food safety alongside growing demand for companion animals’ veterinary services. Information technologies and digitalization trends had driven changes in many business sectors, including providing veterinary services thus opening new avenues to overcome the existing challenges this profession is facing. Methods A study was conducted among 244 veterinary practices in Bosnia and Herzegovina. The gathered information related to subjects involving digital presence, the utilization of information technologies, and the business performance. To obtain this information, a personalized questionnaire was utilized as the means for collecting data. Results The study revealed that only 10.2% had a business-associated website, and 54.9% were present on at least one social media platform. The study suggests that a positive impact on annual profit can be achieved through the implementation of effective digital marketing strategies such as web presence, search engine optimization, Google business account existence, website Google advertisement, continuous administration of social media, and social media advertisement. The statistical analysis indicates that Google advertisements, website search engine optimization, and social media advertisements greatly affect annual profit. Discussion Improving digital presence of veterinary businesses with professionally managed websites, use of social media platforms, investment in online marketing strategies, and adopting telehealth services and online access to patient records positively affects business performance and better fits the growing needs of clients and society.

Many wild animal populations are considered endangered due to anthropogenic activities. Wildlife and nature habitat preservation requires holistic and science based approaches supported by adequate regulations. One of the means for wildlife preservation is undoubtedly heath monitoring and investigation of infectious diseases of the wild animal populations, particularly if spillover effects are considered. Even though the theoretical background is well researched, implementation of disease prevention and control measures in wildlife populations entails more challenges than in domestic animal populations. Immediate signs of health disorders in wildlife often become evident when the infectious agent is well established in an area. Additionally, due to unrestricted and often long-range movement of wildlife, diseases are easily spread across borders. Brown bears, indigenous in Europe, are classified by EU regulations as endangered, almost extinct and rare. The wild bear population in Bosnia and Herzegovina shares a genetic lineage with bear populations of neighbouring Croatia, Serbia and Montenegro and is one of the few remaining fragments of bear populations in Europe. The aim of this paper is to describe implemented activities for health and telemetric monitoring of wild bears in the Nature Park Skakavac, Canton Sarajevo, Bosnia and Herzegovina.

The International Organisation for Animal Health (OIE), from the onset of COVID-19 pandemic, promoted One Health in global and national responses. The OIE accentuated the role of the veterinary profession due to testing capacity of animal health laboratories and expertise. Veterinary Faculty Sarajevo through its Veterinary Institute participates in the national veterinary service with diagnostic and advisory roles. It has proactively enhanced the scope and quality of laboratories, including strengthening the interdisciplinarity and internationality. Development achieved through earlier pandemic threats resulted in having laboratory and technical facilities for molecular SARS-CoV-2 detection in the wake of the unveiling COVID-19 pandemic (early 2020). From confirmation of the first COVID-19 cases in Bosnia and Herzegovina (BiH), our staff participated in crisis response teams and, so far, held over sixty media addresses promoting public awareness and science based information. Our laboratories were included in the official detection system and were the first to sequence SARS-CoV-2, then to establish the Alpha COVID-19 variant in BiH human samples and to substantiate one-way virus transmission from humans to pets. The aim of this paper is to describe our activities as a participant in the response to the COVID-19 pandemic, alongside faced challenges and gained experiences.

Background: According to the WHO (2019), more than 1.5 billion people worldwide are infected with soil-transmitted parasites. Previous research in the Federation of Bosnia and Herzegovina (FB&H) was mainly conducted in the area of the Sarajevo Canton. Therefore, the aim of the research was to explore contamination of soil and vegetation with developmental forms of parasites in the other cantons of FB&H. Methods: Between Apr and Oct 2018, a total of 1,618 soil and vegetation samples were taken from 386 different locations in the 9 cantons of the FB&H. Results: Positive samples were observed, 65/66 (98.48%) municipalities/cities and on 239/386 (61.92%) locations. Out of 1,618 samples taken in total (1,263 soil samples and 355 vegetation samples), 357 (22.06%) were positive, out of which 337 (26.68%) and 20 (5.63%) were soil and plant samples, respectively. In total, the following adult and developmental forms were identified: Taeniidae eggs (7.30%), Toxocara spp. eggs (62.08%), Ancylostomatidae eggs (25.00%), Trichuris spp. eggs (9.55%), Capillaria spp. eggs (3.37%), Toxascaris leonina eggs (1.40%), Nematodes larvae (19.38%), Giardia duodenalis cysts (5.06%), Cryptosporidium spp. oocysts (1.4%), oocysts and cysts of different species of Protozoa (3.93%). Conclusion: The identified developmental forms of parasites pose a permanent threat to human health. It is necessary to carry out measures to reduce the contamination of soil and vegetation in coordination with systematic solutions (legislation), paralelly with contribution of animal owners, veterinarians, physicians, ecologists, parents and all the others involved in this issue.

A 12-point checklist in the design and practical application of active surveillance of diseases in aquatic organisms (farmed and wild) has been developed to serve as a methodological approach and guidance for a multidisciplinary team particularly in countries where surveillance expertise is limited. The checklist is based on a review of available main aquatic surveillance references and scientific literature and was further developed based on the outcomes of several aquaculture biosecurity project-related workshops hosted by the Food and Agriculture Organization of the United Nations. The checklist includes the following: (1) scenario setting; (2) defining surveillance objective; (3) defining the populations; (4) disease clustering; (5) case definition; (6) diagnostic testing; (7) study design and sampling; (8) data collection and management; (9) data analysis; (10) validation and quality assurance; (11) human and financial resources and logistics requirements; and (12) surveillance in the bigger picture. For a multidisciplinary approach to disease control, knowledge of fish biology, aquaculture systems and many aspects of aquaculture health management are required. Surveillance needs significant financial investment and must be supported by adequate diagnostic capability, information system management, legal framework and communication networks, with transparent reporting mechanisms to allow rapid disease response for serious diseases of aquatic organisms. It is a stepwise and pragmatic approach that offers a good starting point for addressing disease issues especially in developing countries. It can be used as a model to build targeted surveillance competency and a basic reference when implementing a surveillance programme or improving existing programmes.

Whole Genome Sequence of four samples from COVID-19 outbreaks was done in two laboratories in Bosnia and Herzegovina (Veterinary Faculty Sarajevo and Alea Genetic Center). All four BiH sequences cluster mainly with European ones (Italy, Austria, France, Sweden, Cyprus, England). The constructed phylogenetic tree indicates probable multiple independent introduction events. The success of future containment measures concernig new introductions will be highly challenging for country due to the significant proportion of BH population living abroad.

Background The production of milk and dairy products and their placement on the market represent a constant profit for the farmers/producers in Bosnia and Herzegovina (BH). The profitable operation of the dairy farms is influenced by the reproductive performance of the lactating animals. This study assessed individual animal reproductive characteristics in selected dairy farms and described their reproductive performance indicators. Results The median age at first insemination was 493 days (5th–95th percentile range 429–840), while the age at first calving was 802 days (5th–95th percentile range 708–1168). The median pregnancy proportion at first insemination was 40% (5th–95th percentile range 17–62), while the cumulative pregnancy rate calculated at day-60, day-80, day-100, and day-120 showed that approximately 64% of all pregnancies happened before day-120. The calculated interservice intervals showed that approximately 69% of the repeat breeding animals came back to the oestrus in the period of 18 to 24 days. This is an indication of very good oestrus detection in selected dairy farms. The mean number of services per pregnancy was 2.61 (range 1–12). The median calving-to-first-insemination interval was 62.5 days (5th–95th percentile range 16–408). The calving-to-conception interval was 101 day (5th–95th percentile range 36–506). Finally, the calving interval was 385 days (5th–95th percentile range 329–773). Conclusions There is a need for an organised, regular, and more comprehensive recording system for the reproduction of dairy cattle among dairy farms in Una-Sana Canton. The calculated reproductive measures indicated an undulant trend in reproductive performance among selected dairy farms in Una-Sana Canton. Knowing the apparent reproductive indicators described in this study, the farmers and veterinary authorities may identify and correct areas in their management that contribute to the reproductive underperformance.
