In vivo cells (hyphal bodies) of the hyphomycetous insect pathogen Beauveria bassiana collected from host Spodoptera exigua larval hemolymph were osmotically sensitive and lacked a well-defined cell wall. In light and electron microscope studies, a galactose-specific lectin purified from S. exigua hemolymph, concanavalin A (specific for alpha-mannose), and a polyclonal antibody to B. bassiana cell walls all bound to surfaces of in vitro-produced B. bassiana blastospores; however, none of these… Expand
Uptake of the fluorescent probe FM4-64 by hyphae and haemolymph-derived in vivo hyphal bodies of the entomopathogenic fungus Beauveria bassiana.
TLDR
Results suggest active uptake by different developmental stages of B. bassiana, including haemolymph-derived cells that can evade the insect immune system. Expand
In vivo development of the entomogeneous hyphomycetePaecilomyces farinosus in hostSpodoptera exigua (beet armyworm) larvae
TLDR
Neither phagocytosis of the initially injected in vitro-produced blastospores nor nodule formation around hyphal cells later in the infection process was effective in stopping fungal growth. Expand
Effects of the fungal pathogen, Beauveria bassiana on protein biosynthesis of infected Spodoptera exigua larvae
TLDR
Vegetative development of Beauveria bassiana in the hemocoel of the beet armyworm, Spodoptera exigua did not cause significant alterations in the profile of hemolymph proteins, and hyphal bodies produced germ tubes which invaded host tissues. Expand
Lectin mapping reveals stage-specific display of surface carbohydrates in in vitro and haemolymph-derived cells of the entomopathogenic fungus Beauveria bassiana.
TLDR
Data indicate robust and diverse production of carbohydrate epitopes on different developmental stages of fungal cells and provide evidence that surface carbohydrates are elaborated in infection-specific patterns. Expand
Phagocytosis of lectin-opsonized fungal cells and endocytosis of the ligand by insect Spodoptera exigua granular hemocytes: an ultrastructural and immunocytochemical study
TLDR
Phagocytosis of blastospores of the fungal entomopathogen Paecilomyces farinosus by granular hemocytes from larvae of Spodoptera exigua was studied and actin was concentrated in the pseudopodia of phagocytic granulocytes and may be directly associated with lectin receptor(s). Expand
Vital role for cyclophilin B (CypB) in asexual development, dimorphic transition and virulence of Beauveria bassiana.
TLDR
Altogether, CypB takes part in sustaining normal growth, aerial conidiation, conidial germination, dimorphic transition, stress tolerance and pathogenicity in B. bassiana. Expand
Could insect phagocytic avoidance by entomogenous fungi have evolved via selection against soil amoeboid predators?
TLDR
The data suggest that the ability of the fungal insect pathogens M. anisopliae and B. bassiana to survive insect phagocytic haemocytes may be a consequence of adaptations that have evolved in order to avoid predation by soil amoebae. Expand
Induction of Novel Proteins inManduca sextaandBlaberus giganteusas a Response to Fungal Challenge
TLDR
The results suggest that holometabolous and hemimetabolous insects synthesize novel proteins in response to fungal challenge and that sites of synthesis may be in different cell types (fat bodies or epidermal cells). Expand
In vitro phagocytosis of occlusion bodies of nucleopolyhedroviruses by insect cell lines
TLDR
The results implied that AcMNPV may be released from the engulfed OBs, and Sf-5-5C cells were selected for the advanced study of phagocytosis. Expand
Mas5, a homologue of bacterial DnaJ, is indispensable for the host infection and environmental adaptation of a filamentous fungal insect pathogen.
TLDR
Mas5 is indispensable for the in vitro and in vivo life cycle of B. bassiana by targeting many sets of enzymes/proteins at transcriptional and post-transcriptional levels and is restored by targeted mas5 complementation. Expand

The Role of Surface Components of the Entomopathogenic Fungus Entomophaga aulicae in the Cellular Immune Response of Galleria mellonella (Lepidoptera)
SUMMARY: Larvae of Galleria mellonella (Lepidoptera) displayed a strong cellular reaction to the walled-stage hyphal bodies of the entomopathogenic fungus Entomophaga aulicae (Entomophthorales). InExpand
Function of a galactose-binding lectin from Spodoptera exigua larval haemolymph: Opsonization of blastospores from entomogenous hyphomycetes
TLDR
In vivo studies show that injected P. farinosus cells having galactose receptors are rapidly cleared from S. exigua haemolymph, whereas N. rileyi blastospores are not cleared. Expand
Ultrastructural localization of carbohydrate in cell walls of the entomogenous hyphomycete Nomuraea rileyi
TLDR
Several probes were used in this ultrastructural study to localize polysaccharides in cell walls on conidial germ tubes, hyphal bodies, and mycelia of the entomogenous hyphomycete Nomuraea rileyi, and labelling patterns did not vary from one morphological stage to another. Expand
Lectin binding characteristics of several entomogenous hyphomycetes: possible relationship to insect hemagglutinins
TLDR
Fungal surface sugar residues may be important with respect to insect defense mechanisms against invading cells and render the fungal cells more susceptible to phagocytosis or other insectdefense mechanisms. Expand
Influence of Beauveria bassiana on the cellular defense response of the beet armyworm, Spodoptera exigua
TLDR
B. bassiana appears to possess a multifaceted capability for both suppressing and eluding the cellular defense response of S. exigua larvae. Expand
Characteristics of a galactose-binding hemagglutinin (lectin) from hemolymph of Spodoptera exigua larvae.
TLDR
Hemolymph from Spodoptera exigua larvae agglutinates rabbit and human O erythrocytes and may be involved in the immune response of the insect e.g., by opsonization of microbial (fungal) surfaces which render the invading cells more susceptible to phagocytosis or Agglutination. Expand
Variations in the ability of galactose and mannose-specific lectins to bind to cell wall surfaces during growth of the insect pathogenic fungus Paecilomyces farinosus.
TLDR
Electron microscopy using ferritin and gold probes showed that the galactomannans are located in a loosely bound coating on the cell wall surface, and variations in lectin binding patterns are apparently due to absence of the coat or to rearrangement of carbohydrate components in the coat. Expand
Mode of infection of the corn earworm (Heliothis zea) by Beauveria bassiana as revealed by scanning electron microscopy
TLDR
Direct evidence is presented to show that conidia can also germinate inside of spiracle openings and could invade larvae by this route, and extensive surface hyphal growth, with or without eventual penetration of the integument, is evident. Expand

TLDR
Study of Leptinotarsa decemlineata larvae infected by Beauveria bassiana during ecdysis has enabled the modes of fungal penetration employed to enter the ecdysial cuticle to be defined, showing that molting and hemocytic reactions are, to a certain extent, an effective defense mechanism. Expand

TLDR
Findings indicate that resident macrophages are permissive for intracellular multiplication of P. brasiliensis and that this could be a factor in pathogenicity. Expand
