Tétel Szabadon hozzáférhető A New Non-invasive Method for Collecting DNA From Small Mammals in the Field, and Its Application in Simultaneous Vector and Disease Monitoring in Brushtail Possums(2021) Emami-Khoyi, Arsalan; Agnew, Thomas W.; Adair, Matthew G.; Murphy, Elaine C.; Benmazouz, Isma; Monsanto, Daniela M.; Parbhu, Shilpa P.; Main, Devon C.; Le Roux, Rynhardt; Golla, Tirupathi Rao; Schnelle, Claudia; Alizadeh, Hossein; Csányi, Sándor; Heltai, Miklós; Jansen van, Vuuren, Bettine; Paterson, Adrian M.; Teske, Peter R.; Ross, James G.Tétel Korlátozottan hozzáférhető AMR prevalence in domestic dogs in Hungarian citiesAlamanova, Azhar; Benmazouz, Isma; Cseri , Karolina; Metagenomikai Intézet; DE--Általános Orvostudományi KarThis study investigates the prevalence of ESBL-producing Enterobacterales in dog feces collected from urban green spaces in two major Hungarian cities, Budapest and Debrecen. Of the 399 samples analyzed, 26 isolates of ESBL-producing Enterobacterales were identified. Among these, 88.5% (23/26) demonstrated resistance to three or more antimicrobial classes. The genomic DNA of the bacterial isolates was analyzed using polymerase chain reaction and whole genome sequencing. Most ESBL-encoding genes were plasmid-mediated, suggesting acquired resistance rather than intrinsic. Sequence types, phylogenetic grouping and virulence factors were also determined, revealing a genetically diverse set of isolates.Tétel Korlátozottan hozzáférhető Assessment of landscape vegetation cover in climate change era- utilizing geographical data and remote sensing techniques- case study in Khinis, Kurdistan-IraqJaqsi, Diman; Kövér, László; Benmazouz, Isma; DE--Mezőgazdaság- Élelmiszertudományi és Környezetgazdálkodási KarThe global occurrence of green spaces has observed continuous decline over the last decades and at the same time, agriculture-based regions are increasingly scrambling to find alternative sources of revenue. The study utilized the satellite images of Landsat and Sentinel sensors in different intervals in order to show how remote sensing, geographic information systems (GIS), and Statgraphics Centurion can be combined to analyse the land cover change and conservation actions rationally. The aim is to identify acceptable sites and assess it for sustainable development of a threatened landscape. The study also point out the flaws and weaknesses of the management of an archaeological area in the nature conservation perspective in Khinis area, Kurdistan region. According to the findings analysis of the Landsat and sentinel data from 1977 to 2021 the natural resources (environmental indicators) saw a significant deterioration over the past few decades due to the climate changes and human activities. Therefore, it is suggested that more emphasis of the preservation action and management requested in the area in order to expand nature protection and conservation.Tétel Szabadon hozzáférhető Comparison of Extended-Spectrum Beta-Lactamase-Producing Escherichia coli Isolates From Rooks (Corvus frugilegus) and Contemporary Human-Derived Strains: A One Health Perspective(2022) Nagy, József Bálint; Balázs, Bence; Benmazouz, Isma; Gyüre, Péter; Kövér, László; Kaszab, Eszter; Bali, Krisztina; Lovas-Kiss, Ádám; Damjanova, Ivelina; Majoros, László; Tóth, Ákos; Bányai, Krisztián; Kardos, GáborTétel Szabadon hozzáférhető Corvids in Urban Environments: A Systematic Global Literature Review(2021) Benmazouz, Isma; Jokimäki, Jukka; Lengyel, Szabolcs; Juhász, Lajos; Kaisanlahti,-Jokimäki, Marja-Liisa; Kardos, Gábor; Paládi, Petra; Kövér, LászlóTétel Szabadon hozzáférhető Does the Hooded Crow (Corvus cornix) harbour vancomycin-resistant enterococci in Hungary?(2022) Benmazouz, Isma; Kövér, László; Kardos, GáborTétel Szabadon hozzáférhető Does the Hooded Crow (Corvus cornix) harbour vancomycin-resistant enterococci in Hungary?(2022-12-06) Benmazouz, Isma; Kövér, László; Kardos, GáborVancomycin resistant enterococci (VRE) are high priority nosocomial bacteria with a potential for zoonotic transmission. Thus, its emergence outside health establishments is a major concern. In order to study the prevalence of VRE in wildlife, we collected 221 faecal samples from free-ranging Hooded Crow (Corvus cornix) from urban and rural habitats in Hungary, from March to August 2020. The screening for resistant enterococci was done using bile esculin azide (BEA) agar supplemented with Vancomycin, specific to the screening of VRE. None of the samples from either habitat types yielded VRE. It seems that Hooded Crows from Hungary do not necessarily constitute a reservoir of VREs at present. Nonetheless, a continuous surveillance of VRE in wildlife would be judicious.Tétel Szabadon hozzáférhető Does the Hooded Crow (Corvus cornix) harbour vancomycin-resistant enterococci in Hungary?(2022) Benmazouz, Isma; Kövér, László; Kardos, GáborTétel Korlátozottan hozzáférhető Environmental management of soybean production in Cerrado (Brazil), focusing on conservation agriculture and biodiversity conservationCampos de Paulo, Fernanda; Kövér, László; Benmazouz, Isma; DE--Mezőgazdaság- Élelmiszertudományi és Környezetgazdálkodási KarThe study evaluates soybean production in Mato Grosso, Brazil, using guidelines from the Round Table on Responsible Soy Association. The indicators include deforestation and conversion of natural land, the content of soil organic matter, conservation techniques for maintaining soil quality, and soybean yield using Earth observation data and geoprocessing tools to identify areas suitable for environmental-oriented techniques to manage soybean production while preserving biodiversity. The results show vegetation cover loss throughout the biome (total area of 15.249 km2), including protected areas and biodiversity corridors. The central region, where conservation units and key areas for biodiversity are located, is particularly affected, highlighting the need to expand protected areas. We also identified that soybean is responsible for a high amount of Soil Organic Carbon stock in the target area. The state of Mato Grosso has a large area of integrated systems and direct seeding practices, indicating the need to continuously implement and promote these practices. Our study also suggests promoting integrated crop-livestock-forest (ICLF) systems to maintain high carbon stock content in the soil. The major soybean producers in or intersecting the Cerrado were identified, totaling 23 cities with a yield higher than 365.518 tons. Lastly, we identified areas for attention that can be used as a parameter to establish natural vegetation areas as conservation units limits as well as starting points on where to invest in conservation agriculture practices and environmental monitoring for natural vegetation cover loss.Tétel Szabadon hozzáférhető Investigating the ecology and microbiology of the urban and rural Hooded Crow (Corvus cornix) in Hungary(2024) Benmazouz, Isma; Kövér, László; Kardos, Gábor; Állattenyésztési tudományok doktori iskola; Mezőgazdaság-, Élelmiszertudományi és Környezetgazdálkodási KarUrbanisation is a complex process that creates an interconnected interface that influences humans, wildlife, and the environment. To understand this interface, Hooded Crow's success in cities was studied. First, morphological differences between urban and rural crows were examined. Then, the presence of antimicrobial-resistant bacteria (ARB) in these birds was investigated, focusing primarily on extended-spectrun beta-latamase (ESBL)-producing Enterobacterales and vancomycin-resistant enterococci (VRE). We collected morphometric data from 249 crows from two urban and two rural areas. Urban individuals were smaller than rural ones, displaying shorter tarsi. No other differences were detected. Due to plenty of anthropogenic food sources, urban adult crows seem to be able to maintain a similar body mass as their rural counterparts. Our results also showed that juveniles from urban habitats have longer and larger bills but smaller body sizes, exhibiting shorter tarsi and smaller skulls. However, due to the low sample size of rural juveniles (n =3), these findings are not conclusive. In urban areas, differences between crows seemed to be age-dependent and may be related to the availability of food sources. Young crows from a larger city (Budapest) have longer and thicker bills and better body condition than those from a smaller city (Debrecen). However, lower body conditions in juveniles from Debrecen may also be explained by other factors, such as poor health status. In Debrecen, young individuals captured at the city Zoo were generally bigger in size, with higher body mass, better body condition, more fat reserves, longer bodies, and wider skulls and bills than individuals caught in the other study areas, suggesting that local factors may influence a habitat’s effect on crows’ growth. To assess the prevalence of ARB in Hooded Crows, 264 faecal samples were collected and analysed. Bacteria were cultured, isolated, and identified using MALDI TOF. The susceptibility test was performed following EUCAST recommendations, and ESBL producers were identified per the double-disc synergy method. ESBL genes were identified using PCR, and E. coli isolates were characterised by WGS. Four rural samples and 125 urban ones (7% vs. 60%, chi-square p<0.0001) yielded ESBL-producers with the overwhelming dominance of E. coli (2/4 and 105/125 in rural and urban positive birds, respectively). The blaCTX-M-1 group was the most predominant. None of the samples yielded VRE. Based on the WGS, in addition to the presence of ESBL-encoding genes, particularly blaCTX-M-1/55/15, genes encoding resistance to other antimicrobial classes were also detected, and various virulence genes in association with several plasmids (mainly IncI-1 and IncF plasmid groups), were predicted. Most isolates belonged to B1 and A phylogenetic groups, suggesting that Hooded Crows carry commensal ESBL producers and might serve as reservoirs of ESBL-encoding genes. Overall, 22 sequence types (STs) and 33 distinct core-genome MLSTs were defined. The most prevalent STs were previously described in human and animal isolates including wildlife. Some STs found, such as ST4412 and ST5798, have yet to be reported in humans and/or animals. The high frequency of ESBL producers carried by urban Hooded Crows points out the role of anthropogenic sources in ESBL occurrence. Yet, it seems that Hooded Crows from Hungary are not necessarily reservoirs of VREs. Nonetheless, the prevalence of resistance genes found strengthens the notion that even free-ranging birds, with increasing contact with humans, pose health-related threats. In summary, here we demonstrated the possible link between AMR carriage by the Hooded Crow and its urban adaptation. We believe that understanding what influences the success of wild birds in urban habitats might mitigate the surveillance of AMR emergence in such hosts and potentially help identify appropriate actions.Tétel Szabadon hozzáférhető Is the Hitchcock Story Really True?
