Abstract
Although Mycobacterium spp. often cause disease in domestic birds (chickens and companion birds), there are few data on avian tuberculosis in wild populations, especially in birds of prey. We describe here a case of a young adult female, free-living Eurasian griffon vulture (Gyps fulvus) that was found dead. Granulomas were grossly evident in the lungs at autopsy, and tuberculosis was suspected. Ziehl-Neelsen staining revealed large numbers of intracellular acid-fast-positive bacteria within granulomas. Examination on Löwenstein-Jensen medium was negative, but mycobacteria growth indicator tube medium results were positive. For the molecular detection of Mycobacterium spp., the primer set IS901F and IS901R was used. Positive results were observed on gel electrophoresis, indicating the presence of Mycobacterium avium subsp. avium DNA. Although tuberculosis is not considered to be a common cause of death in wild birds, it undoubtedly deserves special attention because vultures are generally considered to be a species resistant to a large number of pathogens. Determination of the cause of death of griffon vultures is important for future conservation measures for this sensitive wild species.

Abstract
Listeria monocytogenes, the causative agent of listeriosis, is amongst the major food-borne pathogens in the world that affect mammal species, including humans. This microorganism has been associated with both sporadic episodes and large outbreaks of human listeriosis worldwide, with high mortality rates. In this study, the main sequence types (STs) and clonal complexes (CCs) were investigated in all of the 13 L. monocytogenes strains originating from different sources in the Republic of Serbia in 2004-2019 and that were available in the BIGSdb-Lm database. We found at least 13 STs belonging to the phylogenetic lineages I and II. These strains were represented by ST1/ST3/ST9 of CC1/CC3/CC9, which were common in the majority of the European countries and worldwide, as well as by eight novel STs (ST1232/ST1233/ST1234/ST1235/ST1238/ST1236/ST1237/ST1242) of CC19/CC155/CC5/CC21/CC3/CC315/CC37, and the rare ST32 (clonal complex ST32) and ST734 (CC1), reported in the Republic of Serbia, the EU, for the first time. Our study confirmed the association of CC1 with cases of neuroinfection and abortions among small ruminants, and of CC3 and CC9 with food products of animal origin. The strains isolated in 2019 carried alleles of the internalin genes (inlA/inlB/inlC/inlE) characteristic of the most virulent strains from the hypervirulent CC1. These findings demonstrated the genetic relatedness between L. monocytogenes strains isolated in the Republic of Serbia and worldwide. Our study adds further information about the diversity of the L. monocytogenes genotypes of small ruminants and food products, as the strain distribution in these sources in Serbia had not previously been evaluated.

Abstract
Brucellosis is a zoonotic disease caused by Brucella spp. and a major concern for livestock. Most human cases are caused by B. melitensis and clinical presentation is usually a mild febrile illness. However, treatment failure is frequent and more severe complications can occur. In Austria, every human brucellosis is investigated to determine whether it was imported from endemic areas or is the sign of an undetected autochthonous transmission. For this study, 21 B. melitensis strains isolated in Austria between 2005 and 2019 were collected, 17 strains from 15 different patients and four strains from cattle. Whole genome sequencing combined with core-genome MLST analysis was used to characterize these strains. A cluster of seven isolates from 2018 (three human and four cattle isolates) was identified, with fewer than two allelic differences. They corresponded to the only Austrian B. melitensis outbreak that happened over the past 15 years. The other 12 Austrian brucellosis cases were single cases, and geographical origins were available for 8/12. Genomic data was used to locate probable geographical origins and compared with the results of the epidemiological investigations. Austrian strains were compared with 67 published B. melitensis sequences available on NCBI. The result of genomic analysis matched for 7/8 cases with documented conclusion of the epidemiological investigation. Genome analysis also pointed to the geographical origin for three of the four cases with missing epidemiological data. Strains from six cases were grouped together (<40 allelic differences) with 4/6 cases imported from the Balkans. Additional B. melitensis isolates from Serbian animals were analyzed and grouped with this branch, suggesting frequent importation from Balkan countries to Austria. Overall, this study highlights the specificities of human brucellosis in Austria. It also underlines the value of whole genome sequencing as a tool to investigate brucellosis cases, allowing to identify and investigate outbreaks but also to support epidemiological investigation of imported cases. However, the reliability of such methods depends on the number of strains for comparison, which can be challenging in low incidence countries. Increasing the availability of published sequences with documented geographical origins would help establishing genomic-based methods for investigating brucellosis cases.
