Abstract
Herein, we present our findings of an early appearance of the Monkeypox virus in Prague, Czech Republic. A retrospective analysis of biological samples, carried out on the 28th of April, revealed a previously unrecognized case of Monkeypox virus (MPxV) infection. Subsequent data analysis confirmed that the virus strain belongs to the ongoing outbreak. Combined with clinical and epidemiological investigations, we extended the roots of the current outbreak at least back to 16th of April, 2022.

Abstract
Lymphogranuloma venereum (LGV), the invasive infection of the sexually transmissible infection (STI) Chlamydia trachomatis, is caused by strains from the LGV biovar, most commonly represented by ompA-genotypes L2b and L2. We investigated the diversity in LGV samples across an international collection over seven years using typing and genome sequencing. LGV-positive samples (n=321) from eight countries collected between 2011 and 2017 (Spain n=97, Netherlands n=67, Switzerland n=64, Australia n=53, Sweden n=37, Hungary n=31, Czechia n=30, Slovenia n=10) were genotyped for pmpH and ompA variants. All were found to contain the 9 bp insertion in the pmpH gene, previously associated with ompA-genotype L2b. However, analysis of the ompA gene shows ompA-genotype L2b (n=83), ompA-genotype L2 (n=180) and several variants of these (n=52; 12 variant types), as well as other/mixed ompA-genotypes (n=6). To elucidate the genomic diversity, whole genome sequencing (WGS) was performed from selected samples using SureSelect target enrichment, resulting in 42 genomes, covering a diversity of ompA-genotypes and representing most of the countries sampled. A phylogeny of these data clearly shows that these ompA-genotypes derive from an ompA-genotype L2b ancestor, carrying up to eight SNPs per isolate. SNPs within ompA are overrepresented among genomic changes in these samples, each of which results in an amino acid change in the variable domains of OmpA (major outer membrane protein, MOMP). A reversion to ompA-genotype L2 with the L2b genomic backbone is commonly seen. The wide diversity of ompA-genotypes found in these recent LGV samples indicates that this gene is under immunological selection. Our results suggest that the ompA-genotype L2b genomic backbone is the dominant strain circulating and evolving particularly in men who have sex with men (MSM) populations.

Abstract
Syphilis, caused by Treponema pallidum ssp. pallidum (TPA), is a persisting global health problem. Although syphilis diagnostics relies mainly on serology, serological tests have some limitations, and it is recommended that the final diagnosis be supported by additional tests. The purpose of this study was to analyze the relationship between serology and PCR in syphilis diagnostics. From the year 2004 to May 2019, a total of 941 samples were taken from 833 patients suspected of having syphilis, in Czech Republic. In all these samples, both nested PCR detection of TPA and serology testing were performed. Of the 941 samples, 126 were seronegative, 651 were seropositive, and 164 were serodiscrepant. Among seronegative samples (n = 126), 11 were PCR-positive (8.7%). Among seropositive samples (n = 651; i.e., samples positive for both non-treponemal and treponemal serology tests), 368 samples were PCR-positive (56.5%). The remaining 164 serodiscrepant samples included RPR negative and treponemal serological test-positive samples (n = 154) and a set of 10 RPR-positive samples negative in treponemal serological tests. While the first group revealed 73 PCR-positive samples (47.4%), the second revealed 5 PCR positive samples (50.0%). PCR detection rates were highest in primary syphilis, with lower rates in the secondary and undetermined syphilis stages. As shown here, the nested PCR can improve diagnostics of syphilis, especially in seronegative patients and in patients with discrepant serology.

Abstract
OBJECTIVES The aim of the study was to determine the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae co-infections among patients with newly diagnosed syphilis. METHODS In patients with any stage of newly diagnosed syphilis swabs were performed from urethra, rectum, pharynx and cervix according to the gender and type of sexual intercourse. From these smears standard validated nucleic acid amplification tests (NAATs) for Chlamydia trachomatis and Neisseria gonorrhoeae infections were done. RESULTS From 548 (488 men, 60 women) screened patients co-infection was detected in 15.9% of the cases. The majority of the co-infections (86.2%) were asymptomatic. The overall prevalence of chlamydial infection was 11.1% and 8.8% for gonococcal infections. In men who have sex with men (MSM) the prevalence of co-infections was significantly higher (20.0%) than in heterosexual men and women (4.2%) (p < 0.001). In MSM patients the presence of co-infection was significantly associated with HIV infection (p < 0.001). Among MSM 9.6% of the tests detected infection in anorectal site, while prevalence in urethral (2.8%) and pharyngeal (2.4%) localization was significantly lower. In heterosexual patients prevalence was less than 2.0% in all anatomic sites. CONCLUSIONS The implementation of screening tests in case of sexually transmitted infections in patients with newly diagnosed syphilis is an important part in the management of this disease. These results suggest that screening of asymptomatic heterosexual patients leads to detection of minimum co-infections, but in MSM (especially HIV positive) should always be performed at least in anorectal site, where asymptomatic co-infections are common.

Abstract
A recently introduced Multilocus Sequence Typing scheme for Treponema pallidum subsp. pallidum was applied to clinical samples collected from 2004 to 2017 from the two largest cities (Prague and Brno) in the Czech Republic. Altogether, a total of 675 samples were tested in this study and 281 of them were found PCR-positive for treponemal DNA and typeable. Most of the typed samples (n = 281) were swabs from primary or secondary syphilis lesions (n = 231), and only a minority were whole blood or tissue samples (n = 50). Swab samples from patients with rapid plasma regain (RPR) values of 1–1024 were more frequently PCR-positive (84.6%) compared to samples from patients with non-reactive RPR test (46.5%; p-value = 0.0001). Out of 281 typeable samples, 136 were fully-typed at all TP0136, TP0548, and TP0705 loci. Among the fully and partially typed samples, 25 different allelic profiles were identified. Altogether, eight novel allelic variants were found among fully (n = 5) and partially (n = 3) typed samples. The distribution of TPA allelic profiles identified in the Czech Republic from 2004 to 2017 revealed a dynamic character with allelic profiles disappearing and emerging over time. While the number of samples with the A2058G mutation was seen to increase (86.7% in 2016/2017), the number of samples harboring the A2059G mutation was found to have decreased over time (3.3% in 2016/2017). In addition, we found several allelic profile associations with macrolide resistance or susceptibility, the gender of patients, as well as patient residence.

Abstract
Since the notification of the first case of lymphogranuloma venereum (LGV) in the Czech Republic in 2010, the numbers of LGV cases have steadily increased in the country. In 2015, 40 LGV cases were diagnosed, bringing the total for 2010-2015, to 88 cases. The profile of the most affected group, HIV-positive men who have sex with men with a previous sexually transmitted infection, matches that of those described in LGV outbreaks in western Europe.

Abstract
Treponema pallidum subsp. pallidum (TPA) is the causative agent of the sexually transmitted disease syphilis. In the Czech Republic, several hundred cases of syphilis are reported annually; e.g. in 2012, 696 syphilis cases were documented. In the last decades, an increasing prevalence of macrolide resistant TPA strains harboring A2058G or A2059G mutations in the 23S rRNA gene has been reported. Macrolides were used (and rarely are still being used) in the Czech Republic for the treatment of syphilis in patients allergic to penicillin. While 37% of TPA strains were resistant to macrolides between 2004 and 2010, this rate increased to 67% between 2011-2013. High prevalence of A2058G or A2059G mutations and increasing rates of macrolide resistant TPA strains have also been documented in other developed countries. Therefore, macrolides should not be used in the treatment of syphilis.

Abstract
Background Molecular typing of syphilis-causing strains provides important epidemiologic data. We tested whether identified molecular subtypes were identical in PCR-positive parallel samples taken from the same patient at a same time. We also tested whether subtype prevalence differs in skin and blood samples. Results Eighteen syphilis positive patients (showing both positive serology and PCR), with two PCR-typeable parallel samples taken at the same time, were tested with both CDC (Centers for Disease Control and Prevention) and sequence-based typing. Samples taken from 9 of 18 patients were completely typed for TP0136, TP0548, 23S rDNA, arp, and tpr loci. The CDC typing revealed 11 distinct genotypes while the sequence-based typing identified 6 genotypes. When results from molecular typing of TP0136, TP0548, and 23S rDNA were analyzed in samples taken from the same patient, no discrepancies in the identified genotypes were found; however, there were discrepancies in 11 of 18 patients (61.1%) samples relative to the arp and tpr loci. In addition to the above described typing, 127 PCR-positive swabs and whole blood samples were tested for individual genotype frequencies. The repetition number for the arp gene was lower in whole blood (WB) samples compared to swab samples. Similarly, the most common tpr RFLP type “d” was found to have lower occurrence rates in WB samples while type “e” had an increased occurrence in these samples. Conclusions Differences in the CDC subtypes identified in parallel samples indicated genetic instability of the arp and tpr loci and suggested limited applicability of the CDC typing system in epidemiological studies. Differences in treponemal genotypes detected in whole blood and swab samples suggested important differences between both compartments and/or differences in adherence of treponeme variants to human cells.

Abstract
A set of 415 clinical samples isolated from 294 patients suspected of having syphilis collected in the Czech Republic between 2004 and 2010 was tested for the presence of treponemal DNA. Standard serological tests showed that 197 patients were syphilis-seropositive and 97 patients were syphilis-seronegative. In each sample, PCR tests for polA (TP0105), tmpC (TP0319), TP0136, TP0548 and 23S rRNA genes were performed. Samples taken from 91 patients were PCR-positive. Molecular typing of treponemal DNA was based on the sequencing of TP0136, TP0548 and 23S rRNA genes. Treponemal DNA was typeable in samples taken from 64 PCR-positive patients and 9 different genotypes were found. The proportion of treponemal strains resistant to macrolide antibiotics was 37.3%. In the DNA samples taken from 39 patients, a parallel treponemal typing approved by Centers for Disease Control and Prevention was performed. The variants of arp and tpr genes appear to combine independently with sequence variants of TP0136, TP0548 and 23S rRNA genes.

Abstract
Lymphogranuloma venereum is a sexually transmitted disease caused by serovars L1-3 of Chlamydia trachomatis. This infection was originally endemic in tropics and transmitted predominantly by heterosexual contact but since the beginning of the century it spreads in industrialized countries mainly among men having sex with men causing them severe proctitis. In the Czech Republic the first case was diagnosed in 2011. Lymphogranuloma venereum can resemble other forms of anorectal disorders inclusive inflammatory bowel diseases and thus it must be included into differential diagnostic considerations. Definitive diagnosis is based on detection of specific serovars of Chlamydia trachomatis by polymerase chain reaction. In patients with lymphogranuloma venereum it is also necessary to exclude other sexually transmitted diseases, particularly syphilis, HIV and also hepatitis C. The therapy of choice is doxycycline administered for three weeks.

Abstract
We report an occurrence of treatment failure after oral spiramycin therapy in a man with secondary syphilis and a reported penicillin and tetracycline allergy. Molecular detection revealed treponemal DNA in the blood of the patient and sequencing of the 23S rDNA identified an A to G transition at the gene position corresponding to position 2059 in the Escherichia coli 23S rRNA gene. The occurrence of this novel 23S rDNA mutation was examined among 7 rabbit-propagated syphilitic strains of Treponema pallidum and among 22 syphilis patient isolates from the Czech Republic. The prevalence of A2058G and A2059G mutations among clinical specimens was 18.2 and 18.2 %, respectively.

Abstract
The paper describes the clinical picture and management of congenital syphilis. In the introduction the origin of syphilis is mentioned. The etiologic agent -- Treponema pallidum subsp. pallidum (Tp) -- is transmitted to fetus almost exclusively via placenta. Perinatal infections are less frequent, and postnatal infections are only exceptionally. The symptoms of congenital syphilis may be divided into prenatal (syphilis materno-fetalis), neonatal, and rarely seen postnatal. Prenatal symptoms causing the immaturity of fetus are recognizable from the 7th month of pregnancy and associated with miscarriages, premature deliveries of still-born babies or live neonates with congenital syphilis. Neonatal and postnatal symptoms are manifested only after birth. They may present immediately at birth, develop within first two years of life as early congenital syphilis, or (similarly to acquired syphilis) later in life as a late localized form, often seen many years after birth, even at puberty -- late congenital syphilis. The clinical picture depends on many factors -- primarily on the duration of the infection in mother and the stage of pregnancy.

Abstract
Since 1990 there is an upward trend in the incidence of both acquired and congenital syphilis in the Czech Republic. A similar situation exists in other European countries as well. Higher incidence of syphilis is clearly associated with urban agglomerates and sexual tourism destinations. The only way to reduce the number of cases is a consistent application of mandatory preventive and diagnostic measures. These important measures against the spreading of the infection include mandatory serological testing of pregnant women and newborns (from umbilical blood), antibiotic treatment and systematic follow-up of HIV-positive mothers and children. This paper describes the current epidemiological situation of syphilis in the Czech Republic and presents a review of available diagnostic tests and their significance for diagnosis.

Abstract
Syphilis remains a public health problem in the Czech Republic and worldwide. The Czech Republic - until 1993 a part of Czechoslovakia - has a long tradition in public health activities, and STI surveillance is mainly focused on the infections traditionally called venereal diseases - syphilis, gonorrhoea, chancroid, and lymphogranuloma venereum. Campaigns from the early 1950s, were successful in controlling syphilis and gonorrhoea; and chancroid and lymphogranuloma venereum infections are extremely rare. In late 1980s, a low incidence of newly reported syphilis cases was achieved (100-200 cases annually), while around 6500 cases of gonorrhoea were recorded annually during the same period. Health care and prevention of STI diseases in the Czech Republic are based on close cooperation between clinical departments and laboratory and epidemiological services of Environmental Health Offices. Annual statistics showing data on reported cases of ’venereal diseases’, based on ICD-10 codes, are available from 1959. Separate statistical data on other STIs are not available, and aggregated numbers only for Chlamydia trachomatis infections have been presented annually since 2000. Following the political and social changes in the Czech community in 1989, a distinct increase of syphilis was recorded. Between 50% and 60% of notified cases were classified as late latent or of unknown duration. The continuing annual occurrence of congenital syphilis (7-18 cases per year) reported during the 1990s has also been a very serious phenomenon. Cases have been concentrated in large urban areas with a high level of commercial sex activity, and a high proportion of cases is also noted in refugees. While the annual incidence of gonorrhoea gradually decreased from 1994 to 2001 (from 28.5 to 8.9 per 100 000 population), the incidence of syphilis increased in this period from 3.6 to 9.6 per 100 000 population (the highest value was 13.4 in 2001) and in 2000, for the first time in many years, it exceeded the incidence of gonorrhoea.
