During clinical trials, samples from Hungarian patients of different age groups were tested for antibodies against all 3 serotypes of poliovirus, a member of Picornaviridae family. During the virus neutralization serological test, blood samples were titrated using permanent virus concentration. Based on the cythopathic effect observed under a light microscope, the antibody level of the patient was assessed. The 100 people examined were classified into 5 groups based on age and type of original vaccine: I. Newborns, no vaccination given; II. Immunosuppressed patients; III. Born before 1986, received only OPV vaccine; IV. Born between 1992–2005, received a combination of OPV and IPV vaccines; V. Born after 2006, received only IPV vaccine. Results show that vaccination coverage meets all the criteria. None of the immunized persons was seronegative to all three polioviruses. Both IPV and OPV vaccines are effective against poliovirus. Blood samples from newborn babies with no immunization were also examined. Results show that most newborns have maternal antibodies in their blood. Results of group II show that immunosuppression does not have a negative influence on blood antibody levels against polioviruses. In spite of the low number of samples, our results show that seroconversion after immunization in the Hungarian population is adequate. For more accurate results about vaccination coverage in the population, further trials would be necessary.

A long-legged tick was collected from a hibernating greater mouse-eared bat (Myotis myotis) in Baden-Württemberg, Germany. Based on morphological characteristics as well as on partial COI and 16S rDNA gene sequences the tick was identified as an engorged female of Ixodes ariadnae. The greater mouseeared bat is a new host record for this tick species. Taking into account the geographical position of the collection site and the known migration distance of the greater mouse-eared bat, the present data suggest the autochthonous occurrence of I. ariadnae in Germany. This is the first record of I. ariadnae in Germany, and in any country other than Hungary, where this species has been recently discovered.

Reports of Sarcocystis rileyi-like protozoa (‘rice breast disease’) from anseriform birds had been rare in Europe until the last two decades, when S. rileyi was identified in northern Europe and the UK. However, despite the economic losses resulting from S. rileyi infection, no recent accounts are available on its presence (which can be suspected) in most parts of central, western, southern and eastern Europe. Between 2014 and 2019, twelve mallards (Anas platyrhynchos) were observed to have rice breast disease in Hungary, and the last one of these 12 cases allowed molecular identification of S. rileyi, as reported here. In addition, S. rileyi was molecularly identified in the faeces of one red fox (Vulpes vulpes). The hunting season for mallards in Hungary lasts from mid-August to January, which in Europe coincides with the wintering migration of anseriform birds towards the south. Based on this, as well as bird ringing data, it is reasonable to suppose that the first S. rileyi-infected mallards arrived in Hungary from the north. on the other hand, red foxes (Vulpes vulpes), which are final hosts of S. rileyi, are ubiquitous in Hungary, and our molecular finding confirms an already established autochthonous life cycle of S. rileyi in the region. Taken together, this is the first evidence for the occurrence of S. rileyi in Hungary and its region.

Abstract

In this study, faecal samples of four American Staffordshire terrier dogs (used for illegal fighting) were analysed by DNA extraction, molecular-phylogenetic and parasitological methods, in order to examine the occurrence of protozoan, apicomplexan parasites. In one sample, the DNA of Sarcocystis morae was shown to be present. This species was identified based on 100% identity with already reported sequences of S. morae from cervids in Lithuania and Spain. The result was also confirmed by phylogenetic analysis. The sporocysts of the canine S. morae isolate measured 14.95 × 9.75 μm on average. This is the first molecular evidence in support of the final host role of domestic dogs in the life cycle of S. morae. The most likely source of the infection was raw meat given to the examined dog to increase its physical achievement. In conclusion, under similar circumstances dogs may participate in the life cycle of S. morae in a ‘natural way’, shedding sporocysts/oocysts when used for hunting or taken to walks in forested areas.

Összefoglaló. Közleményünkben egy 63 éves férfi esetét ismertetjük, aki fáradékonyság, fogyás miatt végzett laboratóriumi vizsgálatokon igazolódó veseelégtelenség és hypercalcaemia miatt került felvételre Klinikánkra. A területen végzett röntgenvizsgálaton a koponyán frontalisan és a sacrumon csonteltérések (temporofrontalisan 13 mm-es, körülírtabb, mérsékelten intenzív árnyék és az S1-es rés sclerosisa) ábrázolódtak, ultrahangvizsgálat során lépmegnagyobbodás volt látható. Tünetei hátterében endokrin vagy malignus betegség nem igazolódott. A háttérben elsősorban myeloma multiplex merült fel, ugyanakkor azt célzott vizsgálatokkal sem megerősíteni, sem kizárni nem lehetett, így csontvelő-biopszia történt. A vesefunkció-romlás okának tisztázása végett vesebiopsziát végeztünk, melynek előzetes eredménye interstitialis nephritist véleményezett óriássejtekkel. Az angiotenzinkonvertáló enzim szérumszintjének ez okból történő vizsgálata emelkedett szintet mutatott, így esetünket Boeck-sarcoidosis extrapulmonalis manifesztációjának tartottuk. Per os szteroidkezelésre a beteg tünetei egyértelmű regressziót mutattak. A csontvelő- és vesebiopszia eredménye megerősítette a Boeck-sarcoidosis diagnózisát. A sarcoidosis ezen extrapulmonalis formája hypercalcaemiával és veseérintettséggel – de tüdőérintettség nélkül – rendkívül ritka, különös tekintettel a vesét érintő formára. Hypercalcaemia nagyjából 7,9%-ban, veseelégtelenség 1,4%-ban fordul elő. Ezen eset alapján fontos hangsúlyozni, hogy a hypercalcaemia és a veseelégtelenség hátterében a gyakoribb endokrin, malignus, hematológiai okok mellett a Boeck-sarcoidosisnak is fel kell merülnie a differenciáldiagnosztika során.

Summary. We present the case of a 63-year-old male patient who was admitted to our Clinic with fatigue, weight loss, hypercalcemia, renal insufficiency and anemia. X-ray showed lesions on the frontal skull and sacral region. On abdominal ultrasound, splenomegaly was detected. Based on these, myeloma multiplex was the most likely initial diagnosis; this, however, could not be confirmed with targeted serum tests, therefore bone marrow biopsy was performed. To clarify the underlying cause of decreased kidney function, renal biopsy was performed, the preliminary results of which revealed interstitial nephritis accompanied by giant cells. Serum angiotensin converting enzyme level was elevated, which led to the diagnosis of Boeck sarcoidosis with extrapulmonary manifestations. Oral corticosteroid therapy was commenced that was followed by regression of the patient’s symptoms and laboratory abnormalities. Both the bone marrow and the kidney biopsies supported the diagnosis of Boeck sarcoidosis. Presentation of sarcoidosis with hypercalcemia and renal insufficiency but without the involvement of the lungs is extremely rare. Hypercalcemia occurs in about 7.9% and renal insufficiency in 1.4% of the cases. Based on this case, it is important to highlight that in the background of hypercalcemia and renal failure – beside the more frequent causes such as endocrine and hematological diseases, malignancy – one is to consider the possibility of Boeck sarcoidosis as well.

Hard ticks and tsetse flies are regarded as the most important vectors of disease agents in Sub-Saharan Africa. With the aim of screening these blood-sucking arthropods for vector-borne pathogens belonging to the family Anaplasmataceae in South-Western Ethiopia, four species of tsetse flies (collected by traps) and seven species of ixodid ticks (removed from cattle) were molecularly analysed. DNA was extracted from 296 individual ticks and from 162 individuals or pools of tsetse flies. Besides known vector–pathogen associations, in Amblyomma cohaerens ticks sequences of Anaplasma marginale and A. phagocytophilum were detected, the latter for the first time in any ticks from cattle in Africa. In addition, part of the gltA gene of Ehrlichia ruminantium was successfully amplified from tsetse flies (Glossina pallidipes). First-time identification of sequences of the above pathogens in certain tick or tsetse fly species may serve as the basis of further epidemiological and transmission studies.

Kinetoplastids are flagellated protozoa, including principally free-living bodonids and exclusively parasitic trypanosomatids. In the most species-rich genus, Trypanosoma, more than thirty species were found to infect bats worldwide. Bat trypanosomes are also known to have played a significant role in the evolution of T. cruzi, a species with high veterinary medical significance. Although preliminary data attested the occurrence of bat trypanosomes in Hungary, these were never sought for with molecular methods. Therefore, amplification of an approx. 900-bp fragment of the 18S rRNA gene of kinetoplastids was attempted from 307 ixodid and 299 argasid ticks collected from bats, and from 207 cimicid bugs collected from or near bats in Hungary and Romania. Three samples, one per each bat ectoparasite group, were PCR positive. Sequencing revealed the presence of DNA from free-living bodonids (Bodo saltans and neobodonids), but no trypanosomes were detected. The most likely source of bodonid DNA detected here in engorged bat ectoparasites is the blood of their bat hosts. However, how bodonids were acquired by bats, can only be speculated. Bats are known to drink from freshwater bodies, i.e. the natural habitats of B. saltans and related species, allowing bats to ingest bodonids. Consequently, these results suggest that at least the DNA of bodonids might pass through the alimentary mucosa of bats into their circulation. The above findings highlight the importance of studying bats and other mammals for the occurrence of bodonids in their blood and excreta, with potential relevance to the evolution of free-living kinetoplastids towards parasitism.

Absztrakt:

Bevezetés: Magyarországon 2020. március 4-én sikerült először kimutatni a SARS-CoV-2 jelenlétét két iráni beteg felső légúti mintájában. Az első pozitív esetek megjelenését követően felmerült a kérdés, hogy a vírus mikor kerülhetett be Magyarországra, esetleg okozott-e korábban megbetegedést. 2020. március 4-ét megelőzően a kifejezetten SARS-CoV-2-vizsgálatra beküldött 224 légúti minta közül egyetlen sem bizonyult pozitívnak a fent említett 2 minta kivételével. Célkitűzés: A Nemzeti Népegészségügyi Központ Légúti Vírusok Nemzeti Referencia Laboratóriuma célul tűzte ki, hogy a 2020. január 1. és 2020. április 19. között légútivírus-vizsgálatra beérkezett mintákat visszamenőlegesen megvizsgálja az új koronavírus irányában. Módszer: A tanulmányhoz felhasználtuk egyrészt az influenzafigyelő szolgálatban részt vevő, virológiai mintavételezésre is felkért (ún. sentinel) orvosok által rendszeresen vett, hetente beküldött légúti mintákat, másrészt az egyéb, diagnosztikus céllal beérkezett beteganyagokat. A vizsgálatokat real-time PCR-módszerrel végeztük. Eredmények: A sentinel orvosok által beküldött 465 légúti mintából egy sem bizonyult SARS-CoV-2-pozitívnak. Az egyéb (nem SARS-CoV-2) légúti diagnosztikus vizsgálatra érkező 551 minta között sem találtunk március 4-e előtt vett pozitív mintát. Következtetések: Ezen adatok alapján valószínűsíthető, hogy az elsőként 2020. március 4-én diagnosztizált esetek előtt a SARS-CoV-2 nem okozott klinikai tünetekkel járó fertőzést az országban. Orv Hetil. 2020; 161(38): 1619–1622.
