Oral candidiasis are mycoses resulting from the overgrowth of yeasts of the Candida genus, represents a serious problem for patients with leukemia. The mortality rate of this infection has increased due to fungal septicemia, associated with a primary buccal infection. Objective: The aim of our study is to determine the prevalence of oral candidiasis in leukemia patients, identify the Candida spp. in buccal lesions, differentiate the factors that influence their development. Patients and Methods: This is a retrospective and descriptive study conducted over a four-months period from November 7, 2016 to March 2, 2017, including patients diagnosed with leukemia. Sociodemographic, clinical and biological data from patients fulfilling the inclusion criteria were collected and analyzed. The lesion sample was taken and studied by direct exam and culture on Sabouraud Chloramphenicol and Sabouraud Chloramphenicol Actidionne. The identification of the isolated yeast was done by the filamentation test, carbohydrate fermentation and assimilation. Results: 56 patients were included in this study. Most of the cases (48,21%) were positive to oral candidiasis Their average age was 33,86 years, they were mainly made up of men (64.28%). Candida, albicans was the most frequent species found (55,55%), followed by Candida. glabrata (22.22%), Candida tropicalis (14.81%) and Candida krusei (7,40%). The main contributing factor found was parenteral nutrition (55,55%), corticosteroid therapy (55,55%), antibiotherapy (37,03%), neutropenia (25,92%) and diabetes (11,11%). Conclusion: The results suggest that oral candidiasis is a frequent complication in the leukemia patients. C. albicans was the main etiological agent, however, there is an important participation of other Candida species.

Potential of Trichoderma harzianum for biological control of postharvest fungal rot of white yam (Dioscorea rotundata Poir) tubers in storage was studied. Pathogenicity test revealed the susceptibility of healthy looking yam tubers to Aspergillus niger, Botryodiplodia theobromae and Fusarium oxysporum f. sp. melonganae after fourteen days of inoculation. Treatments comprising A. niger, B. theobromae and F. oxysporum each paired with T. harzianum and were arranged in completely randomized design and stored for five months between December, 2015 and April, 2016 and December, 2016 and April, 2017. Results revealed that tubers treated with the pathogenic fungi alone caused mean percentage rot of between 6.67% (F. oxysporum) and 22.22% (A. niger) while the paired treatments produced only between 2.22% (T. harzianum X F. oxysporum) and 6.67% (T. harzianum X A. niger). In the second year of storage, mean percentage rots were between 13.33% (F. oxysporum) and 28.89% (A. niger) while in the paired treatment rots were only between 6.67% (F. oxysporum X T. harzianum) and 8.89% (A. niger X T. harzianum). Tubers treated with antagonist alone produced 0.00% and 2.22% in the first and second year respectively. Result revealed that there was a significant difference (P ≤ 0.05) in mean percentage rot between the first year and the second year except where B. theobromae was inoculated alone, A. niger and T. harzianum paired and B. theobromae and T. harzianum paired. The most antagonized fungus in paired treatment for both years was F. oxysporum f. sp. melonganae while the least antagonized was A. niger and B. theobromae. The study recommended the use of T. harzianum in the control of rot causing pathogens of yam tubers in storage as better alternative ways of reducing tuber rot compared with the use of chemical fungicides which are environmentally hazardous.

Chilly is a common spice crop grown in large quantities in South Asia. India produces 75% of the total chilly crop followed by Nepal at 8% and Bangladesh at 6%, where it is grown primarily by large and small-scale farmers. It can also be found in the kitchen garden. Disease and insect pests are the most significant factors affecting the production of the chilly crop. The viral disease represents a significant threat to chilly production. Recently, 68 viruses have been reported influencing the chilly crop all over the world. Chilly Leaf Curl Virus Disease, Cucumber Mosaic Virus, Tobacco Mosaic Virus, Tomato Spotted Wilt Virus, Potato Virus Y, Alfalfa Mosaic Virus, Pepper Vein Mottle Virus, Beet Curl Top Virus, and Pepper Mild Mottle Virus are among the 68 viruses belonging to seven genera namely, Begomovirus, Cucumovirus, Tobamovirus, Tospovirus, Potyvirus, Alfamovirus and Curtovirus. In chilly cultivation, yield losses vary from 15 to 100%, depending on the virus. This review article is an analysis providing of top ten viruses reported in Chilly, including their geographic range, yield losses, symptomatology, transmission and management in South Asian Countries.

As of now, SARS CoV-2 has been identified as seventh human-infected coronavirus. Certain coronaviruses (CoVs) include SARS-CoV, 229E, HKU1, OC43, NL63 and MERS-CoV, of which SARS-CoV and MERS-CoV are zoonotic and have resulted in high-percentage outbreaks over the past two decades, while rest of them is typically associated with mild upper respiratory diseases. On 11 March 2020 the WHO announced the situation to be a pandemic that threatens humanity with a wide range. Of the new, bat and pangolins are thought to be the possible origins of SARSCoV- 2 inchoation. The COVID-19 pandemic is putting uneven stress on public health systems around the world. To mitigate the impact of this rapidly spreading virus a multidisciplinary collaborative approach is needed. Since all pandemic viruses that emerged in the last century originate in the animal world and the ongoing changes in the respective interfaces between humans, animals and the environment have led to an increase in major predisposing factors that allow zoonotic viruses to emerge as novel human pathogens, 'peacetime' pandemic preparedness efforts should follow a 'One Health approach'.
