“…In Poland, the bovine mycobacteria reservoir is cattle suffering from tuberculosis. Unlike in the United Kingdom, the Polish badger population is not a reservoir of M. bovis and is free of infection (21). Identified spoligotypes of Polish strains are commonly found in Europe (5,18) and the most common spoligotype in these studies, SB2220 according to the Mbovis.org database, was isolated for the first time in Iran in 2013, which is also demonstrative of international transmission.…”

IntroductionSince 2009, Poland has been recognised as a country officially free of bovine tuberculosis (bTB), although in each year of the last five there were from 8 to 18 outbreaks of the disease. In 2008–2016, the largest number of cattle infected with bovine mycobacteria were eliminated in the Masovian Province (the central region of Poland) and the largest number of outbreaks of this zoonosis were recorded in this area. The close proximity of farms where bTB was found led to the suspicion that tuberculosis could have been transmitted between the affected herds. The aim of the study was the molecular characterisation of the pertinent M. bovis/caprae strains and determination of the epidemiological relationship of various bTB outbreaks.Material and MethodsThe material for microbiological tests came from 119 cattle (Bos taurus) from nine herds located in five provinces, neighbouring the Masovian Province.ResultsLaboratory tests of tissue material gave results confirming tuberculosis in 54 (45%) animals. All strains belonged to the Mycobacterium bovis species. A two-step analysis of genetic affinity allowed 50 strains to be identified as phylogenetically closely related and separated between three genetic clusters consisting of 2 to 27 strains.ConclusionBased on the results of genotyping, bTB outbreaks were found in three herds, and three transmission chains were identified among these herds.

“…For example, in the UK, and probably in the Republic of Ireland, the reservoir of M. bovis are badgers [25,26]. Preliminary studies conducted by Lipiec and others prove that in Poland the badger population is free from bTB infections [27].…”

Introduction and objective. Bovine tuberculosis (bTB, bovine TB) is caused by mycobacteria which are grouped within the MTBC. TB in animals is a highly infectious and progressive disease which can be transmitted to humans. Since 2009, Poland has gained official bTB-free status. Despite the official fact of bTB-free status, a dozen bTB outbreaks are still noted each year. Since 2000 in Poland, every year 1/5 of the national herd is subject to intradermal skin TB testing to control the bTB outbreaks in the cattle population. Application, with 5-year intervals between each government-funded skin test, undoubtedly resulted in financial savings. However it also seems to have caused several adverse and worrying events, e.g. an increase in the number of reactors detected and removed from a single tested herd. The objective of this study was the examination of 898 cattle imputed with bTB infection in Poland between 2008-2012. Materials and method. The study concerned a potential epidemic outbreak with suspected bTB transmission. 20 cows came from 3 herds in the same county located in the same province in southern Poland. Results. 134 MTBC strains were identified. In MIRU-VNTR, all isolates showed the same genetic pattern 322532243421232. Based on molecular investigation, the characteristics of M. bovis strains isolated from cattle from 3 different herds confirmed the common source of this zoonotic disease. Conclusions. Although not bacteriologically proven, everything points to the fact that humans were the vector of bovine tuberculosis transmission between herds. This finding confirms transmission between 3 cattle herds in the Małopolskie Province in southern Poland (Podhale). The outbreak of tuberculosis in animals finally compromised public health.

“…In Poland, a pilot study on the prevalence of TB in various animal populations was carried out by Lipec et al ( 2018) and ; however, its presence in badgers and sheep has not been confirmed [14,22,23], even though TB has been found to cause deaths in these species in other countries [24,25,26,27]. Surprisingly, MTBC were not isolated from deer from the Bieszczady region (Podkarpackie Province), where TB has been identified in wildlife.…”

Introduction. Tuberculosis (TB) is a widespread disease known to affect livestock and wildlife, as well as humans. However, its incidence in wildlife remains poorly recognized on the global level. In Europe, the majority of TB cases have been confirmed in red deer, badgers and wild boar.Objective. The aim of the study was to examine the occurrence of TB in Cervidae in Poland, in areas where TB has been detected in cattle and wildlife. Materials and method Head and thoracic lymph nodes were collected from a total of 76 free-living red deer (Cervus elaphus) and roe deer (Capreolus capreolus), from nine Polish provinces during a single hunting season (autumn -winter 2018-19). Samples were subjected to conventional microbiological procedures to isolate mycobacteria. Results. No Mycobacteria was isolated in the material collected from red or roe deer. Conclusions. There is a need to continue monitoring the presence of TB in cattle and other animal species to ensure the protection of public health.
