  • Antimicrobial Resistance in Indicator Microorganisms Escherichia coli and Enterococcus spp. from Healthy Dairy Cattle in Latvia
    Madara Nikolajenko, Liga Kovalcuka, Ivars Lusis, Aija Malniece, Armands Veksins, et al.
    Animals, 2026
    Antimicrobial resistance (AMR) in food-producing animals is a growing One Health concern. However, data on AMR in indicator microorganisms from clinically healthy dairy cattle in Latvia remain limited. This study aimed to characterize the AMR profiles of Escherichia coli and Enterococcus spp. isolated from rectal swabs and bulk-tank milk collected from 18 dairy farms between February and May 2025. Bacterial identification was performed using conventional culturing and MALDI-TOF mass spectrometry, and antimicrobial susceptibility was determined using the disk diffusion (Kirby–Bauer) method, interpreted according to European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines. Resistance levels were further quantified using resistance scores (R-scores) and the Multiple Antibiotic Resistance Index (MARI). In total, 582 E. coli and 428 Enterococcus spp. isolates were recovered from rectal swabs, with E. coli showing the highest resistance to ampicillin (12.5%) and amoxicillin–clavulanic acid (6.7%), whereas resistance to tetracycline was rare (0.3%). Enterobacteriaceae from milk exhibited higher resistance to ampicillin (45.8%) and amoxicillin–clavulanic acid (20.8%). Among Enterococcus spp., resistance was highest to an antibiotic not used in dairy cows in Latvia quinupristin–dalfopristin (69.2%), while resistance to vancomycin and linezolid remained low (0.5% each). Milk-derived enterococci showed a comparable pattern, with additional resistance to streptomycin (25%). Overall, resistance levels and multidrug resistance were low. However, the presence of sporadic resistant isolates and elevated MARI values, particularly in large-scale farms and milk-derived bacteria, highlights the importance of continued AMR surveillance and prudent antimicrobial use in the Latvian dairy sector.
  • Pet owners’ perspectives on veterinary biobanking in Latvia: Awareness, motivations, ethical concerns, and willingness to participate
    Gundega Stelfa, Kaspars Kovalenko, Liga Kovalcuka
    Veterinary World, 2025
    Background and Aim: Veterinary biobanking advances translational research, companion animal health, and the ethical reuse of samples. Its success depends on public engagement and the pet owners’ willingness to contribute biological sam­ples. However, awareness and attitudes toward veterinary biobanking remain largely unexplored in the Baltic region. This study aimed to assess Latvian pet owners’ awareness, willingness to donate, motivations, and concerns regarding veterinary biobanking, and to identify demographic and professional factors influencing participation. Materials and Methods: A cross-sectional online survey was distributed through social media and veterinary clinics across Latvia between April and May 2025. The questionnaire included 49 items covering awareness, willingness to donate, moti­vations, concerns, and demographics. Data from 164 pet owners were analyzed using descriptive statistics, the Chi-square tests with Bonferroni correction, and logistic regression. Results: Only 22% of respondents had prior awareness of veterinary biobanks. Despite this, 76% were willing to donate samples if their pet was seriously ill, and 67% even if their pet was healthy. Motivations included altruism (helping other animals), supporting veterinary research, and potential treatment benefits for their own pets. Key concerns centered on confidentiality (91%), the right to withdraw samples (60%), and control of sample use (45%). Professional background was significantly associated with both awareness (p = 0.0004) and willingness to donate (p = 0.0013). Logistic regression con­firmed that respondents in medical or veterinary professions were more likely to support donation (odds ratio = 3.31, 95% confidence interval = 1.54–7.12, p = 0.002). No significant associations were found with age, gender, education, or religion. Conclusion: This first Baltic survey reveals that Latvian pet owners strongly support veterinary biobanking despite limited awareness. Altruism and the expected benefits of research drive participation, while ethical expectations regarding confi­dentiality, consent, and transparency remain crucial. The findings provide a foundation for developing national veterinary biobanking strategies, improving public communication, and integrating Latvia into European One Health and translational research infrastructures. Keywords: comparative medicine, One Health, pet owners, public attitudes, translational research, veterinary biobank.
  • Prevalence of SARS-CoV-2 in domestic cats (Felis catus) during COVID-19 pandemic in Latvia
    Gundega Mūrniece, Žanete Šteingolde, Svetlana Cvetkova, Olga Valciņa, Ņikita Zrelovs, et al.
    Veterinary Medicine and Science, 2024
    BackgroundThe causative agent of the COVID‐19 pandemic, severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), is of zoonotic origin and has shown reverse zoonotic transmissibility.ObjectivesThe aim of this cross‐sectional study was to investigate the serological and molecular prevalence of SARS‐CoV‐2 infection in the domestic cat (Felis catus) population from Latvia in natural conditions and subsequently perform viral genome analysis.MethodsOropharyngeal and rectal swabs and blood samples were collected from 273 domestic cats during the second wave of COVID‐19 infection in Latvia. Molecular prevalence was determined by using reverse transcriptase‐polymerase chain reaction (RT‐PCR). Serum samples were analysed via double antigen enzyme‐linked immunosorbent assay targeting the antibody against the nucleocapsid protein of SARS‐CoV‐2. Positive swab samples were analysed using whole viral genome sequencing and subsequent phylogenetic analysis of the whole genome sequencing data of the samples was performed.ResultsThe overall SARS‐CoV‐2 RT‐PCR positivity and seroprevalence was 1.1% (3/273) and 2.6% (7/273), respectively. The SARS‐CoV‐2 genome sequences from three RT‐PCR positive cats were assigned to the three common lineages (PANGOLIN lineage S.1.; B.1.177.60. and B.1.1.7.) circulating in Latvia during the particular period of time.ConclusionsThese findings indicate that feline infection with SARS‐CoV‐2 occurred during the second wave of the COVID‐19 pandemic in Latvia, yet the overall prevalence was low. In addition, it seems like no special ‘cat’ pre‐adaptations were necessary for successful infection of cats by the common lineages of SARS‐CoV‐2.

    Rural Sustainability Research, 2022
    Q fever is a widespread disease affecting reproduction in dairy cattle. Several risk factors can increase the possibility of the herd becoming infected and the persistence of infection. The aim of this study was to characterise the dynamics of C. burnetii infection in affected herds and to evaluate reproduction problems and risk factors using a questionnaire within infected and infection-free dairy herds. In total, 25 farms that were serologically positive or shedding C. burnetii DNA in milk and 14 C. burnetii infection-free farms in Latvia answered the questionnaire. Ten positive herds were studied by testing individual blood and milk samples from up to 10 animals at two times separated by 7.5 to 13 months. The number of serologically positive and suspicious animals was higher in the second sampling even though several animals were culled. In the positive herds, the percentage of dystocia, stillborn calves and abortions during the last year was significantly (p=0.001; 0.01; 0.005, respectively) higher than in the negative herds. Several significant factors were found for the presence of Q fever infection, such as the herd size, the regional population density of ruminants, artificial ventilation systems, and frequent farm visitors. Deratisation was less practised in the negative farms and the presence of ticks was observed more often in the negative farms. Only two identified risk factors can be mitigated – the ventilation system and frequent farm visitors. The other factors cannot be changed arbitrarily but they have to be taken into account by decision makers.

    Linda Valkovska, Artjoms Mališevs, Kaspars Kovaļenko, Aivars Bērziņš, Lelde Grantiņa-Ieviņa
    Journal of Veterinary Research Poland, 2021
    Introduction Q fever in dairy cattle has been investigated in Latvia since 2012. In 2015, 10.7% of farms tested positive for the DNA of C. burnetii, its aetiological agent, in bulk tank milk. The presence of C. burnetii DNA and infectious bacteria in dairy products has been assessed in several countries, and because Latvian milk may contain them, parallel assessment in this country is recommended. Accordingly, the present study tested shop and farm retail dairy products from Latvia and included foreign products for comparison. Material and Methods Investigation was carried out of 187 samples of a diverse range of dairy products from 41 Latvian milk producers. Twenty-six comparable samples pooled from Estonia, France, Germany, Greece, Italy, Lithuania, the Netherlands, Poland and Spain were also included. The all-countries total number of fermented milk products was 160. Special attention was paid to products that could be more attractive to children because of their added chocolate, cacao, berry and fruit content. DNA was extracted and amplification of C. burnetii IS1111 was performed using a commercial PCR kit. Results Overall positivity was 60.56%. Domestic products were positive more often (60.96%) than foreign ones (57.69%). Only 26.67% of unpasteurised Latvian cow’s milk samples were positive whereas 76.47% of pasteurised equivalents and 63.13% of fermented milk products were. Sweetened and fruit-containing samples were 71.43% positive. Conclusion The shedding of C. burnetii via milk should be monitored and only milk from healthy animals allowed for sale for direct human consumption without pasteurisation. Raw milk quality and the effectiveness of industrial heat treatment and pasteurisation methods in Latvia and other countries should be carefully assessed to ensure adequate consumer health protection.

    Q fever is an important zoonotic disease worldwide. The main sources of human infection are inhalation of aerosols containing Coxiella burnetii bacteria and exposition to infected materials during parturition or slaughtering. The high-risk group includes people who work directly with infected livestock, such as farmers, veterinarians, veterinary medicine students, slaughterhouse and laboratory staff. Here we present a pilot study of risk-group human seroprevalence to C. burnetii in Latvia. The study included 240 sera samples — 190 from the risk groups and 50 from the control group. Samples were tested with Coxiella burnetii (Q-fever) Phase 1 and 2 IgG ELISA kits. All sera from the control group were negative. The seroprevalence among risk group persons was 8.04–11.54%. No statistically significant differences were observed between genders. The highest percentage of seropositive and equivocal sera samples (25%) were detected in age categories 39–48 years and 49–58 years. Working as a practicing veterinarian or former veterinarian was the only risk factor identified as statistically significant, and belonging to the risk group in general. The geographical distribution of seropositive risk group participants indicated that they tend to located more in the northern, central, and eastern part of the country.
  • Overview of Cattle Diseases Listed Under Category C, D or E in the Animal Health Law for Which Control Programmes Are in Place Within Europe

    Frontiers in Veterinary Science, 2021
    The COST action “Standardising output-based surveillance to control non-regulated diseases of cattle in the European Union (SOUND control),” aims to harmonise the results of surveillance and control programmes (CPs) for selected cattle diseases to facilitate safe trade and improve overall control of cattle infectious diseases. In this paper we aimed to provide an overview on the diversity of control for these diseases in Europe. A selected cattle disease was defined as an infectious disease of cattle with no or limited control at EU level, which is not included in the European Union Animal health law Categories A or B under Commission Implementing Regulation (EU) 2020/2002. A CP was defined as surveillance and/or intervention strategies designed to lower the incidence, prevalence, mortality or prove freedom from a specific disease in a region or country. Passive surveillance, and active surveillance of breeding bulls under Council Directive 88/407/EEC were not considered as CPs. A questionnaire was designed to obtain country-specific information about CPs for each disease. Animal health experts from 33 European countries completed the questionnaire. Overall, there are 23 diseases for which a CP exists in one or more of the countries studied. The diseases for which CPs exist in the highest number of countries are enzootic bovine leukosis, bluetongue, infectious bovine rhinotracheitis, bovine viral diarrhoea and anthrax (CPs reported by between 16 and 31 countries). Every participating country has on average, 6 CPs (min–max: 1–13) in place. Most programmes are implemented at a national level (86%) and are applied to both dairy and non-dairy cattle (75%). Approximately one-third of the CPs are voluntary, and the funding structure is divided between government and private resources. Countries that have eradicated diseases like enzootic bovine leukosis, bluetongue, infectious bovine rhinotracheitis and bovine viral diarrhoea have implemented CPs for other diseases to further improve the health status of cattle in their country. The control of the selected cattle diseases is very heterogenous in Europe. Therefore, the standardising of the outputs of these programmes to enable comparison represents a challenge.

    Q-fever is widespread globally. The goal of this study was to estimate the prevalence of Q-fever infection in Latvia among dairy cattle in 2018–2020, in comparison with that in 2012–2015. The shedding of Coxiella burnetii DNA in milk was assessed. Screening of blood samples of abortion cases for the presence of antibodies against Q-fever and testing of aborted fetuses for C. burnetii DNA were also carried out. Additionally, serum samples from clinically healthy cattle, sheep and goat were included. Overall, 18.34% of milk samples were positive, representing 11.02% of all tested sheds. In total, 20.62% of serum samples from the cattle that suffered abortions were positive or suspicious, representing 12.63% of all sheds. Only 3.33% of serum samples from clinically healthy cattle and 3.42% from sheep and goat were positive. The highest proportion of serologically positive and suspicious samples was observed in cattle that suffered abortion with age from three to nine years, and in the first and third gestation period. One dominant genotype of C. burnetii (MST61) was detected. Ruminant import from abroad was identified as a significant risk factor, as well as the dairy cattle population density.

    Feline coronavirus (FCoV) is ubiquitous in the domestic cat (Felis catus) population. The aim of this study was to determine the prevalence and potential predisposing factors of FCoV in cats of an animal shelter in Latvia and to compare the prevalence between cats in the quarantine area and resident cats in the adoption area. Oropharyngeal and faecal swabs and blood samples were collected from 40 domestic shorthair cats from an animal shelter in Jelgava, Latvia. Swabs were analyzed for FCoV RNA by reverse transcriptase-polymerase chain reaction (RT-PCR). Blood serum samples were tested for FCoV specific antibodies by indirect enzyme-linked immunosorbent assay (ELISA). FCoV RT-PCR positivity in oropharyngeal and rectal swabs was 7.5% (3/40) and 72.5% (29/40), respectively. Additionally, FCoV seroprevalence was 67.5% (27/40). The proportion of cats shedding FCoV within the adoption (72.7%) and quarantine (72.2%) areas was similar (p = 0.55). The prevalence of FCoV faecal shedding in young cats was significantly higher (p < 0.05) than in adult cats. Sex had no significant effect on FCoV RT-PCR positivity. Further studies on larger cat population including different population types are needed to determine the overall prevalence and epidemiological patterns of FCoV infection in Latvia.
