On the surface and inside the body of pets there is a large number of different microorganisms. Some of them are pathogens of humans, and infect both humans and animals, while the others present only an indirect threat for humans. Skin is a large organ that plays an important role. It is in a direct contact with the environment and presents a mean of transmission for the microorganisms that may be transferred to human beings living in the cities. The objective of this paper was to carry out mycological examination of hair from dogs with clinical symptoms of skin diseases. The aim was to determine saprophytic fungi on dog skin and determine how they influence humans. In a one-year period the presence of fungi was analyzed in 72 samples from dogs with skin changes and 32 samples from dogs without lesions. The samples were inoculated on Saburo dextrose agar and incubated at 25oC for 10-21 days. The grown colonies were characterized based on their shape and color, and under a light microcope conidia, macroconidium and conidiophore were identified. On the dogs with lesions, the presence of fungi ranged from 26.38% to 66.66%, but in the group of dogs without lesions fungi were present in 22% to 65.62%. The isolated fungi were identified as: Aspergillus sp., Penicillium sp., Alternaria sp., Mucor sp. i Fusarium sp.

Dogs are animals that are most often kept as pets in the cities. Their health problem may be the cause of infections of humans and animals. Skin changes and etiology factors present important segment of the diseases that disturb health of the pets. The objective of this work was mycology examination of scarifications and skin swabs from dogs with clinical symptoms. The aim was to find out which fungi species can be isolated from the changed parts of the skin, and whether is possible that, besides dermatophyte, saprophyte fungi from the environment may also be the cause of the changes, and to reveal their effect on the host. During a one year period, 67 swabs and scarifications from dogs were examined to detect the presence of fungi. The samples were streaked on Sabourdaud's dextrose agar and incubated for 10-21 days at 25?C. In microscopis examination according to their shape, and color, the colonies were identified as conidia, macroconidia and conidiaophora. From 59, of total 67 samples, the following saprophyte fungi were isolated: Aspergillus sp., Penicillium sp., Alternaria sp., Mucor sp. and Fusarium sp. Occurrence of these fungi means that a considerable increase of this microbiological flora may be expected in homes of the owners. This may be the cause of systemic mycosis and allergies in animals and humans, as well as a possibility of contaminated food and incidence of mycotoxicosis.

A family doctor, as well as a sexologist, gynecologist, in his medical practice encounters problems related to skin diseases significantly affecting the sense of femininity or masculinity. An example of such an issue, especially in gynecology of developmental age, is the problem of skin changes associated with androgenization syndromes. Typical dermatological diseases are sometimes associated with enormous pain, not only physical, but also mental, resulting from the fact that skin disease processes significantly disfigure the body, lower self-esteem and significantly affect the sexual sphere. Selected aspects related to the holistic approach to the issue of pain and suffering, also related to skin lesions, are presented. This issue, like all medical fields, is a source of philosophical reflection. It is inseparable from psychodermatology. The experience of the SARS-CoV-2 coronavirus pandemic, taking into account skin lesions, also prompts a similar search.

Este trabalho foi realizado para avaliar a ação de Trigona sp. como visitante floral e vetor de esporos fúngicos para goiabeira (Psidium guajava L.). As observações foram feitas entre dezembro de 2003 e fevereiro de 2004 em flores de goiabeiras do Setor de Ciências Biológicas, Universidade Federal do Paraná. Foi verificado que três gêneros de abelhas estavam visitando as flores de goiaba: Apis melifera, Bombus sp. e Trigona sp.. Entretanto, Trigona demonstrou ser mais freqüente que as outras durante as observações. A freqüência de visitas de Trigona foi maior durante o início da manhã, decrescendo ao longo do dia. A avaliação dos fungos associados a Trigona demonstrou a presença de 11 gêneros distintos: Acremonium sp., Altenaria sp., Aspergillus sp., Colletotrichum sp., Curvularia sp., Fonsecaea sp., Fusarium sp., Mycelia sterilia, Penicillium sp., Phoma sp. e Rhizopus sp.. 48 % destes representam fitopatógenos potenciais como Alternaria sp., Colletotrichum sp., Curvularia sp., Fusarium sp. e Phoma sp.. Estes dados demonstram que o gênero Trigona pode atuar na disseminação de doenças para diversas culturas, funcionando como vetor de esporos fúngicos para outras plantas.

The antimicrobial activity of vanillin against four bacteria (Pantoea agglomerans, Aeromonas enteropelogenes, Micrococcus lylae, and Sphingobacterium spiritovorun), four fungi (Alternaria sp., Aspergillus sp., Penicillium sp., and Fusarium sp.), and three unidentified yeasts isolated from spoiling fresh-cut mango slices was verified in laboratory media adjusted to pH 5.0. MICs of vanillin against the fungi (12.5 to 13.3 mM), bacteria (10 to 13.3 mM), and yeasts (5.0 to 6.7 mM) indicated that all the test species were sensitive to the antimicrobial effects of vanillin. Fresh-cut mango slices were dipped for 1 min in solutions containing 40 and 80 mM vanillin before being packaged in rigid trays and stored at 5 and 10°C to verify the effects of vanillin on the development of the spoilage microflora. Microbiological analysis for up to 14 days of storage revealed that treatment with 80 mM vanillin significantly delayed (P < 0.05) the development of total aerobic bacteria and yeast and mold populations. Vanillin may be a practical preservative for processing fresh-cut mango.


scholarly journals ABSTRACT Various body parts or organs can be analysed to identify the different diseases in the human body. Fingernail analysis is one of the ways to identify disease in the human body. Nails are the body part which are farthest from the heart and therefore receive oxygen at last. As a result the nails are the first who show the symptoms of a disease in the human body. Fingernails can be easily captured for diagnosis and there are no heavy equipment or no specific conditions required to use nail image for disease diagnosis, like in other tests and scanning processes. Human nails deliver beneficial information about complaints or any nutritive imbalances in the human body depending upon their shape, texture and colour. In human beings, numerous systemic and skin diseases can be easily analyzed through careful examination of nails of both the limbs. A lot of nail illnesses have been found to be primary signs of numerous underlying systemic illnesses. The colour, texture or shape changes in nails are signs of many diseases mainly affecting nails. Considering all these properties of nails a system is proposed that uses digital image processing (DIP) methods for identifying such changes in the human nail to get more precise results and predict numerous diseases effortlessly. With the emerging Internet of Things (IOT) concept the generated report is made available remotely, this will help users to reduce transportation efforts. As the system has to deal with large and private data, the security of data must be ensured. To keep the data confidential, the Blockchain concept which is one of the most emerging concepts in the field of data management is used. The paper contains the implementation of the digital image processing for feature extraction of nail images, usage of IOT (ThingSpeak cloud) for data storage and implementation of Blockchain to keep the system secured and theft free.

Penyu merupakan vertebrata laut yang termasuk kedalam kategori Appendix 1 yang artinya dilarang diperdagangkan secara internasional. Selain itu penyu salah satu hewan yang paling terancam populasinya secara langsung maupun tidak langsung. Kematian tukik penyu disebabkan oleh berbagai faktor, diantaranya kerusakan habitat alami, pencemaran laut, serangan predator dan perburuan daging maupun telurnya untuk kepentingan komersial. Selain itu, menurunnya jumlah populasi penyu juga disebabkan dari infeksi jamur. Adanya jamur juga menjadi masalah di TCEC (Turtle Conservation and Education Center) yang menyebabkan tingginya tingkat kematian tukik dari penyu lekang (Lepidochelys olivacea). Maka dari itu dengan mengetahui jenis jamur yang ditemukan dapat dilakukan pengobatan serta pencegahan sesuai jamur yang menginfeksi. Tujuan dari penelitian ini adalah untuk mengidentifikasi jamur yang ditemukan pada bagian tubuh penyu lekang (L. olivacea) dan cangkang telur penyu gagal menetas. Sampel tukik dari penyu lekang berumur 10 – 14 hari didapatkan dari penangkaran penyu TCEC Bali. Sampel yang sudah diambil kemudian diswab pada media PDA dan diinkubasi selama 7 hari. Setelah itu dilakukan purifikasi hingga didapatkan koloni murni. Tahap selanjutnya yaitu dilakukannya identifikasi genus secara makroskopis dan mikroskopis pada perbesaran 40x dan 100x. Hasil penelitian memperlihatkan bahwa dari 10 sampel jamur yang diambil dari beberapa bagian tubuh penyu seperti pada mata, kaki, leher dan karapas dan cangkang telur gagal menetas saat sampling, didapatkan 15 isolat koloni jamur. Dari 15 isolat tersebut, ditemukan 5 genus Aspergillus sp, 5 genus Fusarium sp, 3 genus Pytophthora sp dan 1 isolat Trichoderma sp. Pada bagian tubuh jamur yang paling banyak ditemukan yaitu pada bagian leher  sebanyak 4 koloni dan masing-masing jenis jamur bisa ditemukan pada bagian leher. Jenis jamur yang paling banyak ditemukan pada cangkang telur penyu lekang yang gagal menetas yaitu jamur Aspergillus sp yang masing – masing memiliki bercak kuning pada cangkang telur. Selain dari cangkang telur yang memiliki bercak kuning didapatkan juga dari cangkang telur yang melunak.  Turtle is a marine vertebrata that belongs to Appendix 1 category which means it is prohibited to be traded internationally. In addition there is a sea turtle one of animals that are most under threat its population is set directly or indirectly. The death of hatchlings sea turtle was caused by various factors, including natural habitat destruction, marine pollution, predatory attacks and the hunting of meat and eggs for commercial purposes. In addition, the declining number of turtle populations is also caused by fungal infections. The presence of fungi is also a problem in TCEC which causes high mortality rates of turtles (Lepidochelys olivacea). Therefore, by knowing the type of fungus that can be found to be treated as well as prevention of appropriate fungi that infect. The purpose of this study was to identify the fungus found in the turtle body part (L. olivacea) and the turtle eggshell failed to hatch. The turtle samples from turtles aged 10-14 days were obtained from TCEC Bali turtle breeding. Samples were taken later in swabbing on PDA media and incubated for 7 days. After that purification to get a pure colony. The next stage is the identification of the genus in macroscopic and microscopic at 40x and 100x magnification. The results showed that from 10 samples of fungus taken from some parts of sea turtle body such as on eyes, feet, neck and carapace, and eggshell failed to hatch during sampling, 15 isolates of fungal colonies were found. Of the 15 isolates, found 5 genera of Aspergillus sp, 5 genus of Fusarium sp, 3 genus of Pytophthora sp and 1 isolate of Trichoderma sp. In the body of the fungus is most commonly found in the neck as much as 4 colonies and each type of fungus can be found on the neck. The most common types of fungus found in eggshell shells that fail to hatch are the Aspergillus sp fungus, each of which has yellow spots on the eggshell. Apart from the eggshell that has yellow spots it is also obtained from the softened eggshell.

Permintaan yang tinggi terhadap komoditas Kedelai seiring dengan peningkatan konsumsi masyarakat pada produk-produk olahannya. Kenyataan tersebut tidak diimbangi dengan peningkatan produktivitas kedelai dalam negeri. Riniarsi (2016) melaporkan bahwa produktivitas kedelai tahun 2016 bahkan mengalami penurunan sebesar 3.95% dibandingkan tahun sebelumnya.  Faktor yang menyebabkan penurunan produksi kedelai salah satunya karena penyakit yang disebabkan oleh virus tanaman. Seiring dengan tren pengurangan bahan kimia sintetis pada praktik budidaya tanaman, aplikasi mikroba endofit indigenous menjadi solusi alternatif dalam pengendalian penyakit yang disebabkan oleh virus. Penelitian ini bertujuan untuk mengetahui keanekaragaman mikroba endofit indigenous pada berbagai bagian jaringan tanaman kedelai dan menguji virulensinya secara in vitro.Penelitian ini menggunakan metode eksplorasi. Hasil eksplorasi cendawan endofit indigenous berjumlah 11 isolat dan bakteri berjumlah 3 isolat. Cendawan endofit indigenous berhasil diisolasi dari seluruh jaringan tanaman, kecuali polong. Keragaman cendawan endofit indigenous tertinggi terdapat pada jaringan akar dan batang, yaitu masing-masing berjumlah 4 isolat. Identitas cendawan endofit indigenous yang berhasil diidentifikasi antara lain adalah Fusarium sp., Verticilllum sp., Alternaria sp., Aspergillus sp., dan Penicillium sp. Adapun 6 isolat lainnya tidak dapat terindentifikasi. Bakteri endofit indigenous hanya terisolasi dari jaringan polong, akar, dan tanah. Seluruh bakteri merupakan golongan bakteri Gram negatif. Berdasarkan hasil Uji Hipovirulensi, terhadap 7 isolat cendawan endofit indigenous yang masuk dalam kategori hipovirulen dan 4 isolat lainnya bersifat virulen. Sedangkan semua isolat bakteri endofit indigenous yang diuji menunjukkan kategori virulen.
