Tuta absoluta (L.) (Lepidoptera: Gelechiidae), a major pest of solanaceous plant species, causes serious losses in the agriculture sector around the globe. For better pest management, entomopathogenic fungi such as Beauveria bassiana and Purpureocillium lilacinum, play an efficient role in suppressing the pest population. The present study was carried out to analyse the effects post fungal infections through proteome profiling using an Orbitrap Fusion Tribrid mass spectrometer. A total of 2,201 proteins were identified from the fourth instar larvae of T. absoluta, of which 442 and 423 proteins were significantly dysregulated upon infection with P. lilacinum and B. bassiana respectively. The potential proteins related to immune systems as well as detoxification processes showed significant alterations after post fungal infection. Studies on T. absoluta proteomics and genomics as well as the consequences of entomopathogenic fungal infection on the immune response of this insect could provide an initial framework for exploring more fungus-host interactions for the development of better strategies for integrated pest management.

Airway associated inflammation in post-transplant cystic fibrosis patients as a predictor of chronic lung allograft dysfunction (CLAD).

Aims: In cystic fibrosis lung transplant recipients (LTRs), graft dysfunction due to acute infections, rejection or chronic lung allograft dysfunction (CLAD) is difficult to distinguish. Characterisation of the airway inflammatory milieu could help detect and prevent graft dysfunction. We speculated that an eosinophil or neutrophil-rich milieu is associated with higher risk of CLAD.

Paracoccidioides are dimorphic fungal pathogens and the etiological agents of paracoccidioidomycosis (PCM). This severe systemic mycosis is restricted to Latin America, where it has been historically endemic. Currently, PCM presents the fewest diagnostic tools available when compared to other endemic mycoses.

Background: Chronic pulmonary aspergillosis (CPA) is a disease commonly caused by Aspergillus fumigatus and other Aspergillus species characterized by cavitary lung lesions. Tea garden population is an agrarian population of Assam, mostly associated with tea plantations. Assam is a major tea-producing state with 803 tea gardens producing approximately 50% of the total tea in India, of which 177 are present in the Dibrugarh district alone.

Objective: The global prevalence of nontuberculous mycobacterial pulmonary disease (NTM-PD) has been steadily increasing. A few small retrospective studies have reported a poor prognosis associated with chronic pulmonary aspergillosis (CPA) as a complication of NTM-PD. Furthermore, the prognostic impact of CPA may have been inadequately assessed due to differences in background factors.

Thiolation, a post-transcriptional modification catalyzed by Uba4-Urm1-Ncs2/Ncs6 pathway in three specific transfer RNAs (tRNAs), is conserved from yeast to humans and plays an important role in enhancing codon-anticodon interaction and translation efficiency. Yet, except for affecting effector secretion, its roles in plant pathogenic fungi are not fully understood. Here, we used Magnaporthe oryzae as a model system to illustrate the vital role of s2U34 modification on the appressorium-mediated virulence.
