Brucellosis in domestic animals is a chronic disease that characterized mainly by reproductive signs cattle, buffaloes, pigs, sheep, goats and dogs.In females the abortion, placenta retention, vaginal secretions, low fertility rate also embryonic neonatal death.In males, regular findings include epididymitis, orchitis, uni-or bilateral testicular atrophy, sperm abnormalities infertility.Lymphadenopathy, hepatopathy, splenomegaly, uveitis discospondylitis may be observed horses, typical...
Orf virus (ORFV) is the etiological agent of Contagious Ecthyma (CE) disease that mainly affects sheep, goats, wild ruminants, and humans with a worldwide distribution. To date, only two strains from Argentinian sheep have been characterized at molecular level there little information on ORFV circulating in Argentina. Here we describe analyze five outbreaks CE goats three geographic regions country: Northwest, Center, Southwest. The phylogenetic analysis based four markers (orf011 partial...
Control and eradication of bovine brucellosis is usually based on the serological detection antibodies. In Argentina, rose bengal test (RB) buffered plate antigen (BPA) are 2 screening tests officially recognized, whereas 2-mercaptoethanol (2ME) tube agglutination (SAT) confirmatory assays currently in use. order to improve diagnosis Patagonia, an indirect enzyme-linked immunosorbent assay (I-ELISA) kit distributed by International Atomic Energy Agency was evaluated. Sera from negative...
This paper describes an indirect enzyme-linked immunosorbent assay (I-ELISA) and a fluorescence polarisation (FPA), each capable of detecting antibody in several species hosts to smooth rough members the genus Brucella. The I-ELISA uses mixture lipopolysaccharide (SLPS) (RLPS) as antigen, recombinant protein A/G conjugated with horseradish peroxidase detection reagent. When using individually determined cutoff values, SLPS/RLPS combined-antigen detected slightly more animals exposed SLPS or...
Forty-four of a flock 117 angora goats in the Rio Negro province Argentina died within four days. Most animals shortly after onset clinical signs, but few course lasted for several Post mortem small and large intestines were filled with watery contents, blood fibrin clots, there numerous ulcers on mucosa. Small areas malacia observed histologically brain. Clostridium perfringens type D pure culture was isolated from kidneys gut contents affected animals. Epsilon toxin identified by mouse...
This is the first report of a spontaneous outbreak Astragalus pehuenches poisoning on farm in Argentine Patagonia, where 63 out 70 cattle died. The main clinical signs affected animals were ataxia, balance loss and progressive emaciation. Purkinje cells presented vacuolation marginalization nucleus. was detected paddock as well ruminal content fecal matter samples animals. Swainsonine concentrations specimens found to be high 0.096%.
'Mal seco' is a grass sickness-like syndrome of horses in Argentina. A histopathological study was made the coeliaco-mesenteric ganglia four with 'mal and that died from other causes. The severity extent lesions found greatest two shortest clinical course. Degenerative changes consisted mainly loss Nissl substance, cytoplasmic vacuoles, neuronophagia, intercellular intracytoplasmic eosinophilic bodies, pyknotic eccentric nuclei. control had no histological lesions. were very similar to those...
Impaction of the gizzard was diagnosed in 33 1-to-4-wk-old lesser rhea (Pterocnemia pennata) raised on farms Patagonia, Argentina. The birds showed anorexia, lethargy, constipation, dehydration, weight loss, and weakness. Necropsy revealed impaction by fibrous material, sand, rocks, rubbish. Also, excess material observed small intestine, intussusception found one chick. present study similar to that reported other ratite species confirmed this disease can affect chicks captivity. This...
A 5-mo-old great rhea (Rhea americana) gradually became emaciated over a 1-wk period and died. Necropsy revealed several small yellow nodules in the lungs. Microscopically, consisted of granulomas containing numerous thin, 4-µm-diameter, septate, branching fungal hyphae. Aspergillus fumigatus grew readily on Sabouraud dextrose agar. This report appears to be first mycotic pneumonia rheas.
