    Opis:
    With regard to antibiotic resistance studies in various model animals in the urban environment, the presented study focused on the rook, many behavioural and ecological aspects of which are important from an epidemiological point of view. A total of 130 Escherichia coli strains isolated from rook faeces during a two-year period (2011–2012) were investigated for antibiotic resistance and virulence. Resistance to ampicillin (60%) and streptomycin (40%) were the most frequent, followed by resistance to fluoroquinolones (ciprofloxacin-22% and enrofloxacin-24%), tetracycline (18%), cotrimoxazol (17%) and florfenicol (14%). Ceftiofur resistance occured in 10.7 % of strains and cefquinom resistance in 1.5 % of strains. Twenty-five E.coli strains with a higher level of MICs of cephalosporins (over 2mg/L of ceftazidime and ceftriaxon) and fluoroquinolones were selected for detection of betalactamase genes (CTX-M, CMY), plasmid-mediated quinolone resistance qnrS, integrase 1, and for APEC (avian pathogenic E.coli) virulence factors (iutA, cvaC, iss, tsh, ibeA, papC, kpsII). Genes of CTX-M1, CMY-2, integrase 1, papC, cvaC, iutA were detected in one strain of E.coli, and qnrS, integrase 1, iss, cvaC, tsh were detected in another E.coli. DNA microarray revealed the absence of verotoxin and enterotoxin genes and pathogenicity islands. The results show that rooks can serve as a reservoir of antibiotic-resistant E. coli with avian pathogenic virulence factors for the human population, and potentially transmit such E.coli over long distances.

    Opis:
    Samples of 30 dead small mammals each were collected on area ‘A’ located in eastern Poland which is exposed to flooding by the Vistula river, and on the area ‘B’, also located in eastern Poland but not exposed to flooding. Kidneys and livers of the mammals were examined by the PCR and nested PCR methods for the presence of hantavirus RNA. Out of 7 species of small mammals examined, the presence of hantaviruses was detected in 4 of them. Hantavirus prevalence was low in Apodemus agrarius (2.6%), the most numerous mammal species, whereas in the remaining 3 positive species (Microtus agrestis, Myodes glareolus, Sorex araneus) this was 12.5–100%. The presence of hantaviruses was detected only in the animals found on area ‘A’ exposed to flooding, and their prevalence was statistically greater compared to area ‘B’ not exposed to flooding (16.7% vs. 0%, p=0.0345). The overall positivity of the examined small mammals population from the areas ‘A’ and ‘B’ was 8.3%. The sequence analysis of the samples positive for hantavirus proved that the amplified products showed 77–86% homology with the L segment sequence of hantavirus Fusong-Mf-731 isolated from Microtus fortis in China. The presented study is the first to demonstrate the occurrence of hantavirus infection in small mammals from eastern Poland, and the first to demonstrate the significant relationship between flooding and the prevalence of hantaviruses in small mammals.

    Opis:
    The aim of the study was to assess the frequency of Borrelia burgdorferi DNA detection in the blood and urine of patients diagnosed with erythema migrans, and compare the results of PCR-based methods with ELISA methodology. The latter was used to detect serum antibodies against Borrelia burgdorferi of the IgM and IgG classes, before and after antibiotic therapy. The study included 86 patients hospitalized in the Department of Infectious Diseases and Neuroinfections in the Medical Academy in Białystok, diagnosed with the erythema migrans phase of Lyme borreliosis. Examinations were carried out twice: the fi rst at the moment of diagnosis (Trial 1), the second after 4 weeks of antibiotic therapy. The study showed that antibiotic therapy in the early phase of borreliosis does not decrease the sensitivity of PCR and that after 4 weeks of therapy (Trial 2), spirochete DNA is still detectable in most patients (45/86). There was no correlation between detectability of spirochete DNA and the presence of antibodies against B. burgdorferi s.l. (assessed by ELISA) during the course of erythema migrans. The largest percentage of positive results in the detection of B. burgdorferi s.l. DNA was observed in patients who simultaneously possessed IgM and IgG antibodies against B. burgdorferi, while the lowest percentage of PCR positive results was among patients with only IgM antibodies.

    Opis:
    A duplex-PCR method, with 2 pairs of primers recognizing sequences of mitochondrial D-loop region, was developed to identify cows’ milk in the milk of goats. The PCR was shown to be specifi c and sensitive, enabling the detection of less than 1% of cows’ milk added to the milk of goats. Simultaneous use of a primer pair for goats’ and cows’ mitochondrial DNA fragment prevented false negative results. The method was applied to track the presence of cow DNA in goat milk available on the Polish market. A total of 54 milk samples from 3 Polish (34) and one foreign producer (20) were examined. In 33 samples, cow DNA was detected, while 21 samples, including all of the 20 samples from foreign producers, produced the goat-specific product only.

    Opis:
    A total of 305 ticks (21 larvae, 243 nymphs, 19 females and 22 males) were collected by fl agging of vegetation in suburban woods of Pisárky Park (city of Brno) from July to October 2002. The midgut of each tick was dissected out and transferred individually into BSK-H medium. After cultivation, all specimens were examined by dark-fi eld microscopy (DFM) for the presence of borreliae. Out of 305 tick samples, 45 were (14.8%) DFM positive. The following polymerase chain reaction (PCR) then revealed 37 (12.1%) samples positive for the presence of Borrelia burgdorferi sensu lato DNA. All 37 samples were further analysed by restriction fragment length polymorphism (RFLP) method. PCR-RFLP analysis revealed 14 strains of B. afzelii (37.8%), 15 strains of B. garinii (40.5%) and 2 strains of B. burgdorferi sensu stricto (5.4%). Four samples (10.8%) showed a mixed population of these genospecies. Two samples produced atypical RFLP pattern which were detected by sequence analysis as B. valaisiana (5.4%). Isolation attempts resulted in 21 spirochaetal strains (including two stains of B. valaisiana). The results show the diversity of B. burgdorferi s.l. in tick population and refer the risk of infection by pathogenic borreliae in Brno.

    Opis:
    Introduction. Diagnostic procedure in Coronavirus Disease 2019 (COVID-19) is based mainly on performing real-time-reverse transcription-polymerase chain-reaction (RT-PCR), which has been accepted as the gold standard method. In some cases, such as mutations of the SARS-CoV-2 genome, variable viral load kinetics or laboratory errors, it can be false-negative. Case report. The case is presented of a 56-year-old man with respiratory tract symptoms, with twice negative results of real-time-reverse transcription-polymerase chain-reaction of nasopharyngeal swabs and positive chest computed tomography, with typical findings for COVID-19 pneumonia. Conclusions. Patients with negative RT-PCR results, but with positive computed tomography findings characteristic for COVID-19, should be treated as well as those infected.

    Opis:
    The presence of Anaplasma phagocytophilum, a tick-transmitted zoonotic pathogen, has been reported in Italy in humans and several animal species, including dogs, but data concerning its prevalence in the Italian canine population are lacking. The aim of this study was to determine the prevalence of A. phagocytophilum infection in hunting dogs which live in geographic areas of central Italy where the infection had been previously detected in wild animals. Sera from 215 hunting dogs were tested by indirect immunofluorescence antibody test (IFAT) to detect antibodies to A. phagocytophilum. Buffy coat samples from the same 215 animals were submitted to a polymerase chain reaction (PCR) assay specific for the A. phagocytophilum 16S rRNA gene. Thirty-two (14.8%) dogs proved to be seropositive with antibody titres from 1:40–1:2,560. The highest seroprevalence was observed in dogs 6–10-year-old. Two seropositive (0.9%) animals were also PCR positive. Sequencing of PCR products revealed gene sequences of A. phagocytophilum in both cases. These results confirm the presence of A. phagocytophilum in the Italian areas studied; thus, the zoonotic potential of this agent should be considered particularly for people, as hunters, at risk of exposure to tick bites.

    Opis:
    A total of 684 Ixodes ricinus ticks (321 nymphs, 184 males, and 179 females) were collected by fl agging lower vegetation in 6 forest districts located on the territory of Lublin province (eastern Poland). Ticks were examined by polymerase chain reaction (PCR) method for the presence of Anaplasma phagocytophilum DNA with two pairs of primers: EHR521/EHR747 for detecting 16S rRNA gene, and LA6/LA1 for detecting ankA gene. To study the relationship between infection in ticks and people occupationally exposed to tick bite, blood serum samples of 261 forestry workers employed in the same forest districts were examined by immunofl uorescence method for the presence of specifi c antibodies against A. phagocytophilum. A total of 70 ticks out of 684 examined (10.2%) showed the presence of A. phagocytophilum 16S rRNA gene. The prevalence of infection was signifi cantly dependent on tick’s stage (χ2=49.2, p<0.00001) and geographical locality (χ2=34.4, p<0.00001). The percentage of I. ricinus females infected with A. phagocytophilum (24.6%) was signifi cantly greater compared to males (6.5%) and nymphs (4.4%) (p<0.00001). Only 19 ticks out of 684 examined (2.8%) showed the presence of A. phagocytophilum ankA gene, signifi cantly less compared to 16S rRNA gene (p<0.00001). The prevalence of infection demonstrated by the presence of ankA gene was also signifi cantly dependent on tick’s stage (χ2=23.6, p<0.00001) but not on locality (χ2=9.8, p=0.082). A signifi cant correlation was found between the presence of A. phagocytophilum 16S rRNA gene in I. ricinus female ticks from the particular forest districts and the serologic response to A. phagocytophilum of forestry workers employed in the same districts (p<0.05). No signifi cant correlation was found between the presence of A. phagocytophilum ankA gene in I. ricinus ticks and serologic response of exposed workers. In conclusion, detection of A. phagocytophilum infection in ticks by PCR with the use of EHR521/EHR747 primers detecting 16S rRNA gene is signifi cantly more sensitive compared to LA6/LA1 primers detecting ankA gene.
