The occurence of Clogmia albipunctata (Diptera Psychodidae Psychodinae) has been confirmed in the territory of the Czech Republic since 2011. Although it is a non-hematophagous species of tropical origin, it presents a human health risk associated mainly with the mechanical transmission of various pathogens. In addition, C. albipunctata is one of the insects that cause accidental myiasis. The aim of this summary is to provide a comprehensive view of Clogmia albipunctata and accidental myiasis related health issues. Two case reports are presented one of drain fly larvae as a putative parasite and the other of the first passive transfer of drain fly larvae to the human body in the Czech Republic.
In order to improve the surveillance of invasive pneumococcal disease (IPD), the National Reference Laboratory (NRL) for Streptococcal Infections implemented whole genome sequencing (WGS) of Streptococcus pneumoniae. This article reports the first WGS data on S. pneumoniae isolates in the Czech Republic.

Thirty-five isolates of S. pneumoniae from IPD recovered in 2017-2019 were selected for WGS. These were serotypes 4, 8, 9V, 19A, and 22F, which were determined by the Quellung reaction in combination with endpoint multiplex PCR (mPCR). Multilocus sequence typing (MLST) is routinely used for more detailed analysis termed sequence typing. The selected isolates were analysed by WGS on the Illumina MiSeq platform. The sequences obtained were processed using the Velvet de novo Assembler software. The assembled genomes were uploaded into the PubMLST database, using the BIGSdbplatform, and then scanned automatically and molecularly characterized. The isolates were compared at three resolution levels seven MLST gthem to aspecific serotype. WGS has also shown its discriminatory power, allowing the assignment of isolates of the same serotype and sequence type to different genetic clusters.

Of the methods used so far in the Czech Republic, WGS allows the most detailed characterization of S. pneumoniae isolates. It is highly desirable to integrate it in the molecular surveillance of IPD in the Czech Republic, similarly to other countries in Europe and in the world.

Sepse vyvolaná gramnegativními bakteriemi mívá odlišné charakteristiky, především vysoký prokalcitonin vs C-reaktivní protein v porovnání se sepsí vyvolanou grampozitivními bakteriemi. Avšak jednotlivá infekční agens, především Streptococcus pyogenes, nemusí do tohoto schématu zapadat, což může vest k nesprávné iniciální volbě antibiotika. Metody Retrospektivní analýza biomarkerů, iniciální volby antibiotické léčby a výsledků léčby u pacientů se sepsí vyvolanou S. pyogenes, Escherichia coli a Staphylococcus aureus. Hodnoty biomarkerů byly porovnány pomocí Kruskal-Wallis testu s následným Dunn post-Hoc testem s prahem p < 0,05. Výsledky Hodnoty prokalcitoninu byly nejvyšší u sepse vyvolané S. L-685,458 manufacturer pyogenes (12,51 ng/ml, IQR 6,26-48,38 ng/ml) oproti sepsi vyvolaná E. coli (4,30 ng/ml, IQR 1,50-10,00 ng/ml, p < 0,001) a S. aureus (0,75 ng/ml, QR 0,34-1,62 ng/ml, p < 0,001). Poměr neutrofilů a lymfocytů vykazoval stejné charakteristiky jako prokalcitonin. Správná iniciální antibiotická léčba byla v souboru S. pyogenes 11,29 % v porovnání s 99,3 % a 100 % u S. aureus a E. coli skupin. Závěr Oproti předchozím studiím byly v našem souboru pozorovány nejvyšší hodnoty prokalcitoninu u pacientů se sepsí vyvolanou S. pyogenes spíše než gramnegativními bakteriemi. Vysoké hodnoty prokalcitoninu imitující gramnegativní zánětlivou odpověď přispěli k ovlivnění výběru iniciální antibiotické léčby (bez znalosti původce), což mohlo vést k vyšší mortalitě u této skupiny pacientů. Proto doporučujeme přehodnocení významu prokalcitoninu v diagnostice sepse pro zlepšení přežití i kvality života pacientů.
Due to mandatory vaccination introduced in the Czech Republic since 1969, only few measles cases were reported annually until recently. However, a rapid increase of cases has been recorded in last two years. In contrast to the pre-vaccination era, in recent measles outbreaks, many cases have been reported among vaccinated adults. Health care workers (HCWs) are particularly at high risk of contact with measles. Therefore, to minimize transmission in health care settings, many hospitals evaluate measles immune status of their HCWs and offer free vaccination to those with too low anti-measles antibody levels. The aim of this study was to evaluate the seroprevalence of IgG antibodies against measles in all HCWs of the Strakonice Hospital.

Anti-measles IgG serum levels were measured using quantitative ELISA.

Almost all HCWs born before 1969, when the mandatory vaccination started, showed high levels of IgG antibodies (93.5%). Contrarily, among previously vaccinated individuals, only 64.8% were seropositive. A high percentage of seronegative or borderline samples was observed even in the age groups who were previously vaccinated with two doses.

In total, 25.4% of all HCWs of the Strakonice Hospital had too low anti-measles IgG levels, and most of them were immunized with one dose of MMR vaccine. Prioritized vaccination substantially decreased the number of staff at higher risk of measles acquisition and, at the same time, of those who would need to be quarantined after exposure.
