Infection with Babesia bovis was diagnosed in a 2‐day‐old female calf apparently transmitted in utero. The calf was born as the second calving to a cross‐bred beef cow permanently on pasture. Diagnosis was based upon identification of B. bovis in peripheral blood smears and clinical signs which included fever, jaundice, pale mucous membranes and convulsions. Anaemia, leucocytosis, thrombocytopenia and lymphocytosis were noted at the febrile acute stage of the disease. The blood smears revealed evidence of regeneration of toxic neutrophils with a left shift, severe spherocytosis and high degree of basophilic stippling. Elevated concentration of aspartate aminotransferase, lactate dehydrogenase, and creatine kinase were also noted, and were probably the result of haemolysis, dehydration and muscle damage because of recumbancy. Elevated total bilirubin concentration following haemolysis resulted in jaundice. The neurological symptoms observed were probably caused by sludging of parasitized erythrocytes in the brain capillaries. The calf recovered following treatment with diminazene aceturate and the recovery was followed up clinically, haematologically and biochemically.  相似文献

Avena sativa L. subsp. nudisativa has the ability to produce naked grains. Genetic studies on the naked trait of oat began over a century ago, but the genetic and molecular factors associated with the expression of this trait have not been fully clarified. The objectives of this study were to evaluate the naked trait in two oat populations of recombinant inbred lines (RILs), to determine the number of genes, to estimate the heritability, and to map genomic regions associated with the naked trait in hexaploid oat. Parental lines and RILs of each population were screened for the naked trait from plants grown in the field over a 2 year period. Based on the phenotypic data, the oat RILs were classed as naked, partially naked, partially hulled and hulled. In both populations and years, a great number of RILs showed variable expressivity for the naked trait. The genetic analysis indicated the action of a major gene (N1) with the action of modifying genes controlling the formation of naked grains. The results of the estimate of heritability show that environmental conditions do not have a great influence in determining the naked trait. The quantitative trait loci analysis detected a genomic region with a large effect on the naked trait that explained more than 50% of the phenotypic variation. Further studies are needed to validate the use of these molecular markers to assist breeding programs to select high quality and stable naked oat cultivars.  相似文献

Clinical, neurological and clinicopathological signs, treatment and outcome of metaldehyde intoxication in 18 dogs     

Yas-Natan E  Segev G  Aroch I 《The Journal of small animal practice》2007,48(8):438-443

OBJECTIVES: To describe the clinical signs, clinicopathological abnormalities and outcome of metaldehyde intoxication in dogs. METHODS: Medical records of dogs presenting between 1989 and 2005 with a diagnosis of metaldehyde toxicity were reviewed retrospectively. Data obtained from the medical record included signalment, history, clinical signs, laboratory tests results, hospitalisation period length, treatments and outcome. RESULTS: Eighteen dogs fulfilled the inclusion criteria. The most prevalent clinical signs were seizures, hyperthermia, tachycardia and muscle tremors. Serum biochemistry abnormalities included increased serum muscle enzymes activities, acidaemia (six dogs) and decreased blood bicarbonate (eight dogs). Treatment was symptomatic and supportive. Hyperbilirubinaemia was observed in two dogs. Diazepam was the most commonly used anticonvulsant followed by phenobarbitone and pentobarbital. General inhalant anaesthesia was required in nine of 18 dogs with seizures unresponsive to anticonvulsants. The survival was 83 per cent (15 of 18 dogs). CLINICAL SIGNIFICANCE: This clinical study recorded, for the first time in the veterinary literature, several clinicopathological abnormalities from severely intoxicated dogs. Metabolic acidosis was common, while acute or delayed hepatotoxicity was an uncommon complication.  相似文献   

Retrospective study of 46 cases of feline haemobartonellosis in Israel and their relationships with FeLV and FIV infections     

Harrus S  Klement E  Aroch I  Stein T  Bark H  Lavy E  Mazaki-Tovi M  Baneth G 《The Veterinary record》2002,151(3):82-85

Forty-six cats with clinical haemobartonellosis were studied; 75 per cent of the cats of known age were two-and-a-half years old or younger, 50 per cent were intact males and 19.5 per cent were castrated males. The predominant signs of the disease were tachypnoea, lethargy, depression, anorexia, infestation with fleas, pale mucous membranes, icterus, emaciation, dehydration, splenomegaly, anaemia, leucocytosis, increased activities of alanine aminotransferase and aspartate aminotransferase, and azotaemia. Thirty-eight per cent of the cats that were tested for feline leukaemia virus (FeLV) antigen were positive, and 22 per cent of those tested for feline immunodeficiency virus (FIV) antibodies were positive. The prevalence of both FeLV and FIV was much higher than in the general Israeli cat population. The cats infected with both Haemobartonella felis and FeLV had a significantly lower body temperature, were more anaemic and the mean cell volume of their erythrocytes was greater than in the cats with haemobartonellosis alone.  相似文献

Inheritance of Aluminum Tolerance and its Effects on Grain Yield and Grain Quality in Oats (Avena Sativa L.)     

Itamar Cristiano Nava  Carla Andréa Delatorre  Ismael T. de Lima Duarte  Marcelo Teixeira Pacheco  Luiz Carlos Federizzi 《Euphytica》2006,148(3):353-358

Summary Aluminum toxicity due to the cation Al⁺³ is a major factor limiting yields in acid soils. Wide genetic variability to aluminum tolerance is found in oat genotypes. The objectives of this study were to determine the number of genes controlling aluminum tolerance in oats and to verify if any detrimental effects were present of the aluminum tolerance genes on grain yield and grain quality in Al⁺³free soils. Aluminum tolerance was estimated as the average regrowth of the main root after exposure to toxic levels of Al⁺³ in a hydroponic solution under controlled conditions. The number of genes controlling that trait was estimated from the distribution of the average root regrowth frequencies in a population of 333 recombinant inbred lines (RIL's) in generations F_5:6 and F_5:7. The effects on grain yield and grain quality were assessed in a subpopulation of 162 RIL's chosen based on their aluminum tolerance response. Aluminum tolerance in the evaluated population was controlled by one dominant major gene with the tolerant genotypes carying Al _a Al _a and the sensitive ones al _a al _a alleles. No detrimental effects of the Al _a allele on grain yield or grain quality were detected.Part of the Master of Science dissertation of the first author  相似文献

Alpha-chloralose poisoning in dogs and cats: a retrospective study of 33 canine and 13 feline confirmed cases     

Segev G  Yas-Natan E  Shlosberg A  Aroch I 《Veterinary journal (London, England : 1997)》2006,172(1):109-113

Alpha-chloralose (AC) is an anaesthetic compound also used as a rodenticide, and has dose-dependent central nervous system mixed effects of excitation and depression. The objectives of this study were to detail the clinical and clinicopathological characteristics, as well as the treatment and prognosis, of AC toxicosis in dogs and cats. Medical records were retrospectively reviewed for AC poisoning between the years 1989 and 2004, and 33 dogs and 13 cats were included in the study. The most common clinical signs were seizures, muscle tremor, hyperaesthesia, hypothermia, salivation, myosis, stupor, coma and ataxia. Coma was more common, while salivation and ataxia were less common in cats compared to dogs. Although hypothermia was very common, especially in cats (90.9%), hyperthermia was frequently observed in dogs (21%). Treatment in all patients was supportive and symptomatic, and the most commonly used anticonvulsants were diazepam and barbiturates; however, severe unresponsive seizures in three dogs had to be controlled with inhalant gas anaesthesia. The hospitalisation period was 1-3 days, and the overall mortality rate was 6.5%. Alpha-chloralose poisoning seems to have a favourable prognosis in dogs and cats.  相似文献
