Published: February 2025

Background and Clinical Significance: Klebisella variicola belongs to the Klebsiella pneumoniae complex. It is a Gram-negative, facultative anaerobic, and nonmotile bacillus, mainly isolated in plants. However, as an emerging human pathogen, it has been isolated in immunocompromised patients with urinary tract infections, pneumonia, and bacteremia. K. variicola infection in pregnancy, responsible for acute chorioamnionitis, has never been reported. Case Presentation: We present a case of a twin pregnancy at 17 + 5 weeks in which chorioamnionitis and fetal inflammatory responses such as funisitis and chorionic vasculitis were due to an ascending infection of K. variicola. The pathogen was isolated postmortem in fetal blood and tissues and the placenta using MALDI-ToF mass spectrometry (MALDI-ToF MS). The accuracy of this microbiological diagnosis sheds further light on the epidemiology and virulence of K. variicola in the prenatal setting. Conclusions: In the case of miscarriage, microbiological investigations on the fetus should always be recommended to identify the exact microorganism in order to target the medical treatment and manage subsequent pregnancies.

Macrofungi are a group of fungi with important ecological functions and economic value in forest ecosystems. In this study, the species diversity and community composition of macrofungi in different areas, vegetation types, and elevation gradients from the Lingshan Natural Scenic Area and Xiaolongmen National Forest Park of the Dongling Mountains, Western Beijing were investigated. A total of 1379 specimens were collected. All specimens were identified by morphological and molecular methods, resulting in the identification of 311 species belonging to two phyla, four classes, 18 orders, 74 families, and 147 genera. The alpha diversity analysis indicated that the alpha diversity was significantly different among different vegetation types. The Betula spp. and Populus davidiana of the Lingshan Natural Scenic Area, and Quercus liaotungensis of Xiaolongmen National Forest Park had higher macrofungal alpha diversity. The difference in alpha diversity between the two areas was not significant. The principal coordinate analysis indicated a significant difference in macrofungal community composition among different vegetation types. The fungal community composition of the two areas was also significantly different. The fungal species richness and unique species tended to increase and then decrease with increasing elevation. The species composition of neighboring elevation gradients was more similar. The macrofungal species richness and the number of unique species were not significantly affected by elevation gradient. The vegetation types with higher fungal alpha diversity in the Dongling Mountains were Betula spp., Populus davidiana, and Quercus liaotungensis, and there were abundant fungal species in deciduous broad-leaved mixed forests. Macrofungal diversity and community composition was significantly affected by vegetation type. To better protect the macrofungi, the protection of these four vegetation types in the Dongling Mountains should be strengthened in the future.

Objective. To assess the epizootic and clinical-epidemiological situation regarding the incidence of hemorrhagic fever with renal syndrome in the Primorsky Krai in the period 2019–2023. Materials and methods. A retrospective clinical and epidemiological study of the incidence of hemorrhagic fever with renal syndrome enrolled 149 patients. The epizootic process in populations of small mammals in natural and synanthropic foci was examined according to generally accepted methodologies. Results. The activity of natural foci of hemorrhagic fever with renal syndrome, caused by the circulation of three orthohantaviruses (Hantaan virus and its Amur and Seoul genotypes), remains significant, with a predominance of the Amur carrier in the body of the Korean field mouse. This occurs despite a clear downward trend in the incidence (from an average annual rate of 4.9 to 1.6 per 100,000 population in 2019). Severe and complicated forms of the infection notably prevailed (23.5 %), with high mortality rates (up to 11.5 % in 2023). Some clinical and pathogenetic prognostic criteria for the severity of hemorrhagic fever with renal syndrome were identified in the early stages of the disease. Conclusion. The severity of the disease course and difficulties in primary diagnosis define the hemorrhagic fever with renal syndrome to be a significant public health concern in the region.

Published: February 2025

Bencana banjir adalah bencana alam yang terjadi akibat dari faktor alam dan faktor manusia. Seperti yang terjadi pada Kelurahan Rapak Dalam Kota Samarinda yang banjirnya diakibatkan dari faktor alam dan manusia. Bencana banjir di Keluarhan Rapak Dalam berawal dari semakin pesatnya pembangunan kawasan perumahan dan permukiman yang tidak memperhatikan fungsi dari guna lahan yang ada. Sehingga banyak kasus perubahan fungsi lahan yang awalnya didominasi oleh sawah dan semak belukar kini banyak berubah menjadi perumahan dan permukiman serta penggalian dan pertambangan tanah, batu dan pasir. Sehingga mempengaruhi fungsi infiltrasi dan mengakibatkan limpasan. Banjir akibat faktor alam seperti curah hujan serta topografi dari Kelurahan Rapak Dalam yang termasuk kawasan dataran rendah juga menjadi faktor penyebab banjir. Di tahun 2018 pada Kecamatan Rapak Dalam terjadi banjir besar setelah 10 tahun terakhir dengan ketinggian banjir 1.20 meter dan sekitar 10.000 jiwa harus mengungsi akibat durasi hujan yang lama serta DAS Rapak Dalam yang merupakan DAS utama pada Kelurahan Rapak Dalam tidak lagi mampu manampung air limpasan dan mengakibatkan banjir. Hingga saat ini intensitas kejadian banjir makin sering terjadi walupun dengan curah hujan yang tidak derasa namun jika dalam intensitas waktu yang lama maka akan terjadi limpasa. Sehingga dibutuhkan adanya strategi yang dapat membantu menangani permasalahan banjir walaupun marak terjadi perubahan fungsi lahan. Dalam mengembangkan strategi mitigasi diperlukan adanya permodelan hidrologi yang memprediksi kejadian banjir akibat perubahan guna lahan dengan intensitas curah hujan yang sama pada tahun 2018. Pemodelan hidroligi digunakan dalam menghitung debit banjir agar dapat memberikan strategi mitigasi yang sesuai agar dapat optimal.

Mangrove ecosystems play a crucial role in maintaining the ecological balance of coastal areas, including protection against abrasion, providing habitat for marine species, and acting as a carbon sink. This study aims to identify indicator species and analyze biodiversity in Darunu Mangrove Park, Darunu Village, Wori Subdistrict, North Minahasa Regency. The research was conducted over three months (May–July 2024) using a line transect method for vegetation data collection. The results show that three dominant mangrove species were identified: Rhizophora apiculata, Rhizophora mucronata, and Sonneratia alba. R. mucronata exhibited significant dominance, both in terms of mature trees and saplings, and had the highest Important Value Index (IVI). The mangrove species diversity in this area is classified as low, with the. Diversity Index (H’) indicates an imbalance in the ecosystem's species composition. The Dominance Index (C) and Evenness Index (E) analyses indicate strong dominance by certain species, particularly R. mucronata. This study recommends the importance of enhanced monitoring and more intensive conservation efforts, including the replanting of threatened mangrove species and raising community awareness of mangrove ecosystem conservation.

Goal. Determination of optimal methods of phytosanitary monitoring and strategies for controlling the number of harmful arthropods based on ecologically safe preparations on ornamental crops in urban green areas.
Methods. Monitoring of the phytosanitary state of urbophytocenoses was carried out by the method of route surveys of plantations. The method of visual detection of the phytophagous or traces of its vital activity on the trunk, branches, shoots and leaves was used to examine the crown of plants. To record the density of phytophagous colonies and to identify species, individuals were collected using a transparent adhesive film. Colored glue traps were used to monitor Lepidoptera, Diptera, Coleoptera and other insects.
Results. The use of colored glue traps in the closed soil of the Botanical Garden named after Acad. O.V. For the purpose of monitoring insects, Fomina made it possible to identify 16 species of phytophages from 4 orders: aphids (Aphidoidea) Myzus persicae Sulz., Macrosiphum rosae L., Idiopterus nephrolepidis Davis.; coccids (Coccoinea) Nipaecoccusnipae Mask, Pseudoccus longispinus (Targioni Tozzetti), Coccus hesperidum L., Diaspis boisduvalii Sign., Kuwanaspis pseudoleucaspis Kuw.; whiteflies (Aleyrodoidea): Aleurodes vaporariorum Westw., Bemisia tabaci Genn., B. argentifolii Bellows; thrips (Thysanoptera): Thrips tabaci Lind., Heliothrips haemorrhoidalis Bouche., Frankliniella occidentalis Pergande, Echinothrips americanus Morgan, Thrips palmi Karny. Among the seven colors we used to determine the degree of attractiveness of insects that are common in indoor soil, the most attractive color is yellow. Using color traps in open ground to monitor species such as Phyllonorycter issikii Kumata (a plant pest of Tilia L.) and Cameraria ohridella Deschka & Dimic (a plant pest of Aesculus L.) showed that three colors were most attractive to these species: blue, green and red. A high level of effectiveness of the drug Phytocomplexon-1 has been established in comparison with other options. For the pests Quadraspidiotus perniciosus, Hyphantria cunea and Cydalima perspectalis, this drug showed the highest efficacy rates ranging from 79.5 to 92.4%.
Conclusions. The use of colored glue traps in closed and open ground conditions is an important element for insect monitoring. It is important to consider the color of traps when planning strategies for monitoring and controlling plant pests, which can improve the effectiveness of plant protection measures. The high level of effectiveness of new environmentally safe preparations based on rapeseed oil and plant extracts against various types of harmful organisms has been confirmed. In particular, the drug Phytocomplexon-1 proved to be the most effective for insects. The study indicates the prospects of using environmentally safe methods of plant protection in botanical gardens and megacities.
