Hemolysin of the stable fly, Stomoxys calcitrans

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1980
Abstract 1. 1. A hemolysin found in whole fly homogenates and in midgut homogenates of Stomoxys calcitrans (L.) is heat labile, has a slightly acidic pH optimum, and is non-dialyzable. 2. 2. Hemolytic activity is enhanced by dialysis but not by removal of Ca2+ alone. 3. 3.

The possible role of Stomoxys calcitrans in equine sarcoid transmission

The Veterinary Journal, 2018
The association between bovine papillomavirus (BPV) and equine sarcoids is well established, but it is unclear how the virus spreads. Although evidence in support of viral spread through direct animal contact exists, this does not explain sarcoid development in isolated equids. BPV DNA has been detected in flies, which could indicate that these insects

On the transmissibility of Eperythrozoon suis by Stomoxys calcitrans and Aedes aegypti

Veterinary Parasitology, 1993
The stable fly, Stomoxys calcitrans (Linnaeus), and the yellow fever mosquito, Aedes aegypti (Linnaeus), were utilized to determine their capability to transmit Eperythrozoon suis Splitter between swine. Three groups of each insect in each trial were allowed to feed on a pig previously infected with E.

Hemolymph constituents of the stable fly, Stomoxys calcitrans

Comparative Biochemistry and Physiology Part A: Physiology, 1992
Abstract 1. 1. Organic constituents of the hemolymph of the adult stable fly, Stomoxys calcitrans (L.) were analysed before and after the first blood meal. 2. 2. Hemolymph trehalose concentration decreases after a blood meal and remains low throughout digestion. 3. 3. Hemolymph glucose concentration decreases immediately following a blood

Transcellular absorption of lipids in the midgut of the stablefly, Stomoxys calcitrans

Journal of Insect Physiology, 1977
Abstract The midgut of Stomoxys calcitrans is subdivided into several zones. The last of these, the lipoid zone is responsible for the absorption of digestion products. The ultrastructure of the lipoid zone cells is described. Analysis of E.M. autoradiographs of 3 H-label derived from absorbed fatty acids shows a strong non-random distribution of ...

Interactions between stimuli in the induction of probing by Stomoxys calcitrans

Journal of Insect Physiology, 1970
Abstract A fly which has settled on the skin of a live host is subjected simultaneously to a number of physical, visual, and chemical stimuli. The probing response to selected host stimuli tested in isolation, was described in a previous paper ( Gatehouse , 1970).

Evaluation of mechanical transmission of Anaplasma marginale by Stomoxys calcitrans

Research in Veterinary Science
The objective of this study was to investigate the mechanical transmission of Anaplasma marginale to cattle by Stomoxys calcitrans. The S. calcitrans were obtained in field condition and their offspring (first generation) were used in this study originating in the laboratory.

[A Stomoxys calcitrans outbreak on a dairy farm].

Angewandte Parasitologie, 1986
In late summer and autumn of 1982 Stomoxys calcitrans disturbed cattle on a dairy farm and scourged the people working there. Both actively and passively Stomoxys calcitrans got into the cowsheds from its nearby breeding sites on open silos. The successful fly control combined sanitary measures with the application of pyrethrum insecticide aerosol.

Digestive enzyme secretion in Stomoxys calcitrans (Diptera: Muscidae)

Cell and Tissue Research, 1976
Enzyme assays and morphological and histological studies show that the opaque zone midgut cells of the hematophagous fly Stomoxys calcitrans are responsible for the production of proteolytic digestive enzymes and that these are secreted into the gut lumen via membrane bound vesicles (MBV). The secretory cycle can be summarized as follows: initially the

An immunocytochemical investigation of trypsin secretion in the midgut of the stablefly, Stomoxys calcitrans

Insect Biochemistry and Molecular Biology, 1996
Musca domestica trypsin antibody cross-reacts with polypeptide bands of M(r) 25,000 and 30,000 showing proteolytic activity from Stomoxys calcitrans midgut extracts. Secretory granules from the main enzyme-secreting region, the opaque zone, stained heavily with the trypsin antibody in both unfed and blood-fed flies.
