Songbirds widely disperse ticks that carry a diversity of pathogens, some of which are pathogenic to humans. Among ticks commonly removed from songbirds, the blacklegged tick, Ixodes scapularis, can harbor any combination of nine zoonotic pathogens, including Babesia species. From May through September 2019, a total 157 ticks were collected from 93 songbirds of 29 species in the Canadian provinces of Ontario and Québec. PCR testing for the 18S gene of Babesia species detected Babesia odocoilei in 12.63% of I. scapularis nymphs parasitizing songbirds in Ontario and Québec; none of the relatively small numbers of Ixodes muris, Ixodes brunneus, or Haemaphysalis leporispalustris were PCR-positive. For ticks at each site, the prevalence of B. odocoilei was 16.67% in Ontario and 8.89% and 5.26% in Québec. Of 31 live, engorged I. scapularis larvae and nymphs held to molt, 25 ticks completed the molt; five of these molted ticks were positive for B. odocoilei. PCR-positive ticks were collected from six bird species—namely, Common Yellowthroat, Swainson’s Thrush, Veery, House Wren, Baltimore Oriole, and American Robin. Phylogenetic analysis documented the close relationship of B. odocoilei to Babesia canis canis and Babesia divergens, the latter a known pathogen to humans. For the first time in Canada, we confirm the transstadial passage of B. odocoilei in I. scapularis molting from larvae to nymphs. A novel host record reveals I. scapularis on a Palm Warbler. Our findings show that B. odocoilei is present in all mobile life stages of I. scapularis, and it is widely dispersed by songbirds in Ontario and Québec.

AbstractAutomatic bird detection in ornithological analyses is limited by the accuracy of existing models, due to the lack of training data and the difficulties in extracting the fine-grained features required to distinguish bird species. Here we apply the domain randomization strategy to enhance the accuracy of the deep learning models in bird detection. Trained with virtual birds of sufficient variations in different environments, the model tends to focus on the fine-grained features of birds and achieves higher accuracies. Based on the 100 terabytes of 2-month continuous monitoring data of egrets, our results cover the findings using conventional manual observations, e.g., vertical stratification of egrets according to body size, and also open up opportunities of long-term bird surveys requiring intensive monitoring that is impractical using conventional methods, e.g., the weather influences on egrets, and the relationship of the migration schedules between the great egrets and little egrets.

The following notes were assembled in arranging the Protarchoides material in the National Collection. In establishing the identity of Protarchoides mellipes (Prov.) it has been found necessary to synonymize one species. A species allied to mellipes is described as new and a table is provided for the separation of the four known North American species. The recording of Trichiosoma as host for a member of this genus is further evidence of the close relationship of the genus with Protarchus Foer.

AbstractTo study the function of the 49 kDa excretory-secretory (ES) protein gene (P49) of Trichinella, the genes was amplified by RT-PCR from RNA of Trichinella spiralis and Trichinella nativa and several Chinese Trichinella isolates of domestic animals, and sequenced after being cloned. The amplified products of these parasites produced bands of about 950 bp. The 97.2 % to 100 % nucleotides identity and 94.3 % to 100 % identity of deduced amino acids among P49 gene of these Trichinella strains showed the close relationship of these parasites. The P49 gene of T. nativa was cloned into the BamHI site of the prokaryotic expression vector pET-30a, and the recombinant vector was expressed. The expressed product was 40.8 kDa in size. In Western blot analysis, the expressed product was reactive to sera of mice infected with T. nativa, T. spiralis and their Chinese geographical strains.

The present review describes the concept of probiotics for plants and analyzes the prospects for using actinomycetes as producers of these drugs. The minimum requirements for plant probiotic microorganisms are proposed, similar to those for human probiotic microorganisms. These are utility, efficiency and safety for plants, as well as mandatory isolation from plant samples. It is noted that these requirements are usually met by endophytic and rhizosphere microorganisms that stimulate plant growth and provide them with protection from phytopathogens. Evidence is given for the possibility of attributing actinomycetes to probiotic plant bacteria, due to the close relationship of these microorganisms with plants, their wide distribution in populations of endophytic and rhizosphere microorganisms, and the presence of phytoregulatory activity. The review provides examples of genera and species of actinomycetes that are promising producers of probiotics for agronomically important crops. The most studied and commercialized of them are representatives of the Streptomyces genus. The current state, prospects and problems in commercialization of probiotics based on actinomycetes are discussed. probiotic microorganisms of plants, associative actinomycetes, endophytes, rhizosphere, biological preparations

Kertas kerja ini menganalisis peranan Ustaz Abu Bakar al-Baqir iaitu lama reformis tempatan yang konsisten menentang British sehingga terpenjara pada 1948. Beliau turut menubuhkan Maahad al-Ehya Assyariff untuk memodenkan sistem pendidikan pondok di samping meniupkan semangat kemerdekaan kepada pelajar dan masyarakat di sekelilingnya. Objektif kajian ini adalah untuk mengetengahkan sumbangan Ustaz Abu Bakar al-Baqir sebagai seorang ulama dan pejuang kemerdekaan menentang British sekitar 1934 sehingga 1957 di Perak. Kajian ini berbentuk historiografi yang menggunakan kaedah kualitatif dengan pendekatan analisis kandungan. Dua jenis sumber digunakan dalam kajian ini iaitu sumber primer dan sekunder. Sumber primer adalah seperti mendapatkan dokumen dan fail di Arkib Negara Malaysia, sumber pejabat kolonial British di samping menemu bual ahli keluarga dan murid Ustaz Abu Bakar al-Baqir. Sumber sekunder pula diperoleh melalui buku, surat khabar dan kertas kerja seminar yang berkaitan dengan perjuangan beliau. Hasil kajian mendapati para pelajarnya terdedah dengan semangat kemerdekaan ini ekoran guru-guru reformis dari Indonesia yang terdedah dengan perjuangan menentang Belanda mengajar di Maahad al-Ehya Assyariff. Selain itu, hubungan baik Ustaz Abu Bakar al-Baqir dengan Ibrahim Yaakub selaku penggerak Kesatuan Melayu Muda (KMM) dan Dr. Burhanuddin al-Helmy yang memimpin Parti Kebangsaan Melayu Muda (PKMM) menjadikan Maahad al-Ehya Assyariff sebagai markas politik menentang British sehingga tertubuhnya Parti Hizbul Muslimin di bawah pimpinan Ustaz Abu Bakar al-Baqir. Kata kunci: Maahad al-Ehya Assyariff, Hizbul Muslimin, British, Kaum Muda, Parti Kebangsaan Melayu Malaya (PKMM), Kesatuan Melayu Muda (KMM). This paper attempts to analyze the role played by Ustaz Abu Bakar al-Baqir, a local reformist religious leader who consistently opposed the British until he was imprisoned by them in 1948. He established the Maahad al-Ehya Assyariff with the aim of modernizing the religious education system besides stoking the spirit of freedom among his students and the society around him. The objective of this study is to highlight the contributions of Ustaz Abu Bakar al-Baqir as a religious leader as well as a freedom fighter who opposed British rule in Perak from around 1934 until 1957. This is a historiographical research which uses qualitative methodology with a content analysis approach. Two different sources of information are used for this study namely primary and secondary sources. Primary sources include documents and files from the Malaysian National Archives and official documents from the British Colonial office, besides interviewing family members as well as former students of Ustaz Abu Bakar al-Baqir. On the other hand, secondary sources include books, newspapers and seminar report relating to his struggle. The findings of the study show that his students were exposed to the struggle for Independence through the direct influence of the reformist teachers from Indonesia who were teaching at the Maahad al-Ehya Assyariff. These teachers had already been involved in the fight against the Dutch colonialists in Indonesia. In addition to this, the close relationship of Ustaz Abu Bakar al-Baqir with Ibrahim Yaakub, the primemover of Kesatuan Melayu Muda (KMM) and Dr. Burhanuddin al-Helmy, the leader of Parti Kebangsaan Melayu Muda (PKMM), projected Maahadal-Ehya Assyariff as the political front that opposed British rule until the founding of the Parti Hizbul Muslimin under the leadership of Ustaz Abu Bakar al-Baqir. Keywords: Maahad al-Ehya Assyariff, Hizbul Muslimin, British, Kaum Muda, Malay Nationalist Party (MNP), Young Malays Union.

Method of project multicriteria decision synthesis with decision success criterion is used for realisation of construction projects which require a proper analysis of constituent parts in close relationship of components. Scheme of this method is presented in Fig 3. Multicriteria decision project may be divided into several interrelated building processes and smaller projects. On every level of the whole project, the decision of closeness to ideal solution method is made and, on the basis of the obtained results, several alternatives are chosen. On every separate level, a number of alternatives is selected by the method user. It depends on complexity of the project and on requirements of interested parties. At the last decision stage, there is performed a synthesis using the chosen alternatives and relying on their interrelations. During decision process on the intermediate stages, having eliminated irrational alternatives, effective and precise results are achieved. The developed multicriteria decision synthesis method is one of the elements of the newly created group of multicriteria decision methods. Using this method algorithm, software is prepared that entirely manages the whole decision process from database filling to calculation and result processing.
