1. The liver of the dog in which necrosis has been produced by injection of haematoxic immune sera is characterized in the less marked forms by a storing up of nitrogen in the persisting living cells, while in the diffuse forms the total nitrogen content is but slightly above the normal. This last
Staphylococci cause bovine mastitis, with Staphylococcus aureus being responsible for the majority of the mastitis-based losses to the dairy industry (up to $2 billion/annum). Treatment is primarily with antibiotics, which are often ineffective and potentially contribute to resistance development.
The authors performed the experimental model of infarct-like myocardial lesions in rats treated with large doses of ISP. Myocardial necrosis was assessed on the basis of serum enzyme changes as well as of gross and microscopic findings. The infarct size was measured by a direct enzymatic method
Black widow spider (Latrodectus mactans) envenomation is found throughout both the temperate and tropical latitudes, and is one of the leading causes of death from arthropod envenomations worldwide. The venom is highly neurotoxic, affecting the presynaptic motor endplate to allow massive
Pseudozyma flocculosa is related to the model plant pathogen Ustilago maydis yet is not a phytopathogen but rather a biocontrol agent of powdery mildews; this relationship makes it unique for the study of the evolution of plant pathogenicity factors. The P. flocculosa genome of ~23 Mb includes 6877
Antimicrobial peptides (AMPs) form part of the innate immune response, which is of vital importance in fish, especially in eggs and early larval stages. Compared to antibiotics, AMPs show action against a wider spectrum of pathogens, including viruses, fungi and parasites, are more friendly to the
Necrotizing fasciitis is a serious and increasingly common human disease which can be caused by an infection with beta-haemolytic streptococci (BHS) of Lancefield groups A, C or G, spreading rapidly in the loose connective tissue over the muscle fascia. To facilitate study of its pathogenesis, we
Two M5.1 and M15.2 B complex congenic lines of Fayoumi chickens were evaluated for body weight loss and faecal oocyst counts as parameters of avian coccidiosis. M5.1 chickens exhibited resistance to E. maxima compared with M15.2. To correlate the differential responses of the M5.1 and M15.2 lines to
To determine whether transcriptional levels of channel catfish (Ictalurus punctatus) genes are differentially regulated between a first infection with Aeromonas hydrophila and a re-infection, suppression subtractive hybridization (SSH) was performed in this study using anterior kidney cDNA after the
Eighteen new genes, adenosine A1 receptor (ADORA1), complement component 4-beta (C4b), complement component 8-beta (C8b), chemokine ligand 19 (CCL19), chemokine ligand 21 (CCL21), chemokine ligand 25 (CCL25), chemokine receptor 2 (CCR2), chemokine receptor 5 (CCR5), chemokine receptor 4 (CCR4),
The contribution of a number of extracellular products of Staphylococcus aureus to the virulence of the organism for mice was studied by comparing a wild-type strain with various mutants derived from it in three virulence tests: (1) subcutaneous and (2) intravenous challenge in normal mice, and (3)
This study aimed to investigate the effect of typhaneoside on ventricular remodeling and regulation of the PI3K/Akt/mTOR autophagy transduction pathway in rats with heart failure after myocardial infarction.The effects of typhaneoside on the general To investigate the influence of genetic differences in the MHC on susceptibility to avian coccidiosis, M5.1 and M15.2 B-haplotype-disparate Fayoumi chickens were orally infected with live Eimeria maxima oocysts, and BW gain, fecal oocyst production, and expression of 14 immune-related genes were
