Exotic reptiles originating from the wild can be carriers of many different pathogens and some of them can infect humans. Reptiles imported into Slovenia from 2000 to 2005, specimens of native species taken from the wild and captive bred species were investigated. A total of 949 reptiles (55 snakes, 331 lizards and 563 turtles), belonging to 68 different species, were examined for the presence of endoparasites and ectoparasites. Twelve different groups (Nematoda (5), Trematoda (1), Acanthocephala (1), Pentastomida (1) and Protozoa (4)) of endoparasites were determined in 26 (47.3%) of 55 examined snakes. In snakes two different species of ectoparasites were also found. Among the tested lizards eighteen different groups (Nematoda (8), Cestoda (1), Trematoda (1), Acanthocephala (1), Pentastomida (1) and Protozoa (6)) of endoparasites in 252 (76.1%) of 331 examined animals were found. One Trombiculid ectoparasite was determined. In 563 of examined turtles eight different groups (Nematoda (4), Cestoda (1), Trematoda (1) and Protozoa (2)) of endoparasites were determined in 498 (88.5%) animals. In examined turtles three different species of ectoparasites were seen. The established prevalence of various parasites in reptiles used as pet animals indicates the need for examination on specific pathogens prior to introduction to owners.

In the year 2000 an epidemiological research was undertaken on the health status of free-living pigeons in the city of Ljubljana, Slovenia. A total of 139 pigeons were captured and examined for the most common bacterial, viral, and parasitic diseases. Serum samples, oropharyngeal and cloacal swabs as well as samples of droppings and feathers were taken from the captured birds. Antibodies to paramyxovirus type 1 were found in 84.2% of the sera examined, and 23.7% of birds were serologically positive to Chlamydophila psittaci. Antibodies to avian influenza virus were not detected. Salmonella spp. were isolated from 5.7% of the cloacal swabs. Trichomonas gallinae was clinically suspected and then microscopically confirmed using oropharyngeal swabs in 7.9% of examined birds. Eimeria spp. was identified in 71.9%, Capillaria sp. in 26.6% and Ascaridia columbae in 4.3% of droppings samples examined. Of the ectoparasites, Columbicola columbae and Campanulotesbidentatus compar were found.

Background: Leptospiral infections in poikilothermic (cold blooded) animals have received very little attention and the literature concerning natural infections of these animals is limited. The aim of this study was to determine the prevalence of leptospiral antibodies in reptiles, imported into Slovenia and intended to be pets in close contact with humans. A total of 297 reptiles (22 snakes, 210 lizards and 65 turtles) were tested for specific antibodies against serovars of Leptospira interrogans sensu stricto using the microscopic agglutination test (MAT). Live cultures of different serovars were used as antigens. MAT was performed according to standard procedures and the degree of reaction was interpreted by estimating the percentage of agglutinated leptospires. Samples showing titres of ≥ 50 against one or more serovars were considered as positive. Results: Antibodies against seven pathogenic serovars of L. interrogans sensu stricto were detected in 46 of 297 reptiles. Among 22 snakes, specific antibodies against pathogenic serovars of three Leptospira species (L. interrogans, L. kirschneri and L. borgpetersenii) at titre levels from 1:50 to 1:400 were detected in 6 snakes. In 31 of 210 lizards, specific antibodies were found in titres from 1:50 to 1:1000 and, finally, among 65 turtles (terrapins and tortoises), 9 had specific antibodies at titre levels between 1:50 and 1:1600. Animals imported from non-EU countries showed significantly higher prevalence (25.0%; 95 confidence interval: 16.7–33.3%) than animals from EU member states (10.4%; confidence interval: 6.1–14.7%). Conclusions: Reptiles may be considered as potential reservoirs of L. interrogans sensu stricto. Origin of the animals is a risk factor for presence of leptospiral antibodies, especially in lizards. Special attention should be focused on animals from non-EU member states.

Infectious laryngotracheitis (ILT) is an acute, highly contagious infectious disease of the upper respiratory tract in chickens and other poultry species that causes significant economic losses in countries worldwide. Between 2017 and 2019, seven outbreaks of mild to severe respiratory disorders with high suspicion of ILT occurred in commercial and backyard poultry flocks in Slovenia. In all submissions, infection with ILT virus (ILTV) was confirmed by PCR, which is the first report of ILT in Slovenia. Circulating ILT strains were characterized by the sequence and phylogenetic analysis of two fragments of the ICP4 gene. Four strains—three detected in non-vaccinated flocks and one in a flock vaccinated against ILT—were identical or very similar to the chicken embryo–origin live virus vaccines, and the other three were closely related to Russian, Chinese, Australian, and American field strains and to tissue culture origin vaccine strains. As in other diseases, coinfections with other respiratory pathogens in confirmed ILT cases may cause a more severe condition and prolong the course of the disease. In our study, coinfections with Mycoplasma synoviae (7/7 tested flocks), infectious bronchitis virus (5/5 tested flocks), Mycoplasma gallisepticum (4/7 tested flocks), Ornithobacterium rhinotracheale (3/4 tested flocks), and avian pox virus (1/2 tested flocks) were confirmed, indicating the importance of these pathogens in the occurrence of ILT infections.

Animal welfare is a multidimensional concept that includes several physical and psychological parameters of the animal. The aim of this study was to assess animal welfare during transportation and in Slovenian beef, pork, and poultry slaughterhouses. A questionnaire was used for this study. Several parameters of animal welfare were rated on a 5-point scale, such as health status, animal behavior, lairage or transport vehicle conditions, and driver regulation compliance. The scale was also used for the second part of the study. This consisted of two studies: (1) self-assessment by slaughterhouse employees and livestock transport drivers and (2) animal welfare observational assessment performed by two veterinarians. The results were compared with each other. Ten large slaughterhouses and nine livestock drivers took part in the survey. The results showed that slaughterhouse employees knew more about animal welfare than livestock truck drivers, but both groups were not sufficiently familiar with animal welfare laws and regulations. This study found that the experts’ assessments were generally lower than the self-assessments of employees and livestock drivers. Based on the research findings, it can be concluded that there is a need to improve the awareness and knowledge of slaughterhouse employees and livestock drivers regarding animal handling and animal welfare regulations.
