The west to east oriented graves of an Early Avar period cemetery came to light at Szihalom-Budaszög in 1996. Two clay mugs turned on a fast wheel bespeak local Gepidic ceramic traditions. A wooden amulet capsule can likewise be linked to Pannonian and Transylvanian communities with a Merovingian culture. The gold and gilt bronze mounts of the capsule suggest the burial of an individual from the community’s elite. The gold mounts of the capsule are decorated with four masks arranged in a cross-like design. The stylistic and iconographic parallels to the masks point towards Italy and the regions north of the Alps. The capsule provides evidence for syncretic beliefs: the amulet was probably believed to have both pagan magical and Christian protective properties. The small cemetery was used by a local Gepidic community with good contacts with Western Europe living under the overlordship of the Avar Khaganate.

Sixty-eight Actinobacillus pleuropneumoniae strains were isolated from porcine acute pleuropneumonia cases from different parts of Hungary between 2000 and 2014. A total of 41 isolates were identified as A. pleuropneumoniae bio-type I and 27 strains as biotype II based on cultural, morphological and biochemical characteristics. The aim of this study was to evaluate metabolic fingerprinting in the species-level identification of A. pleuropneumoniae isolates. Utilisation of carbon sources by these field isolates and six reference strains was characterised by the Biolog system (GN2 Microplate, MicroLog3 Version 4.20.05 software). Twenty-nine field strains were correctly identified by the Biolog system as A. pleuropneumoniae, 36 strains as A. lignieresii, two strains as H. paraphrohaemolyticus and one strain as A. equuli after 24 h of incubation. Among the six A. pleuropneumoniae reference strains the Biolog system identified one strain as A. pleuropneumoniae, four as A. lignieresii and one as H. paraphrohaemolyticus. There was no correlation between biotypes and serotypes of A. pleuropneumoniae and the carbon source utilisation pattern and species identification by the Biolog system. our data indicate that the efficacy of the Biolog system used here could be improved by including phenotypes of more A. pleuropneumoniae strains representing a wider geographical occurrence into the database.

A total of 255 Actinobacillus pleuropneumoniae isolates were collected from 634 lung samples representing 70 swine herds in Hungary between January 2012 and June 2016. On the basis of the indirect haemagglutination test 77 independent strains were included in the evaluation after the elimination of duplicate or multiple serotypes from the same herd. In the case of 7 herds strains of two different serotypes were identified. Fourteen Hungarian A. pleuropneumoniae isolates from the culture collection of the Department of Microbiology and Infectious Diseases, isolated before 2012, were also included in the evaluation (one each from 12 herds and two each from two herds, where two serotypes occurred). Out of the altogether 91 A. pleuropneumoniae strains 72 strains belonged to biotype I and 19 strains could be allocated to biotype II. In Hungary, the most common serotypes were serotype 2 (39.5%), 13 (15.4%), 8 (8.8%) and 16 (8.8%), but serotypes 9 (5.5%), 11 (3.3%) and 12 (3.3%) were also isolated. Twelve strains (13.2%) were untypable.

Two hundred and twelve
strains were isolated from soil, nasal and rectal swabs of horses and immunocompromised human patients in Hungary and serotyped using Prescott’s serotyping system. One hundred and forty-seven strains (69.3%) belonged to serotype 1, 22 strains (10.4%) to serotype 2, 6 strains (2.8%) to serotype 3 and 1 strain (0.5%) to serotype 4. Serotypes 5, 6 and 7 were not found and 36 strains (17%) could not be typed. Serotype 1 (72%) was the type most commonly isolated from clinical samples of foals or from the soil of horse facilities. Six out of 8
strains from humans belonged to serotype 2, and two human strains were untypable. The data show that the prevalence of
serotypes varies in different geographic areas of the country.

Three new serotypes were found among Rhodococcus equi strains, which could not be assigned into any of the seven serotypes of Prescott’s system. Fortythree R. equi strains out of 44 previously nontypable ones isolated in Hungary could be allocated into one of the three new serotypes using the agar gel immunodiffusion (AGID) test. The three new suggested serotypes are serotype 8 (proposed reference strain: HNCMB-138003), serotype 9 (proposed reference strain: HNCMB-138004) and serotype 10 (proposed reference strain: HNCMB-138005). Hyperimmune sera produced in rabbits against the new serotypes and reference strains gave precipitation only with their homologous antigens, and no crossreactions were observed. All of the previously nontypable isolates from clinical samples of horses (lung abscesses, intestinal lymph nodes, mediastinal lymph nodes) proved to be serotype 8, while strains of serotypes 8, 9 and 10 could be isolated from nasal and rectal swabs of horses and from the soil. Serotype 9 dominated among the previously nontypable strains of swine origin. One of the previously nontypable human strains was serotype 10. This serotype was also isolated from pigs, horses and the soil. The description of the three new serotypes can help us reveal new correlations between the host species, geographical origin and serotype of R. equi isolates.
