Twenty ostrich chicks that died at, or within, 1 week after hatching were examined from 7 farms with poor (43 to 75%) hatchability. All chicks had anasarca and 15 had mild, generalised, acute degenerative changes in the complexus and pelvic limb muscles. One had fibrinoid degeneration of arterioles. Biochemical examinations produced no evidence of deficiencies of selenium, vitamin A or vitamin E. The syndrome was related to high relative humidity during incubation. Malpositioning also was a cause of embryo mortality. 相似文献

ABSTRACT In vitro grown kiwifruit (Actinidia deliciosa, Liang and Ferguson) plantlets were treated with two humic fractions distinguished by two different relative molecular mass and characterized through their elemental composition and 13Carbon (C) nuclear magnetic resonance. The effects exerted on plant growth, root morphology, and nutrition were evidenced by means of leaves and roots mineral content, root respiration, and nitrate reductase activity. The two humic substances differentially influenced the studied parameters. The lower molecular fraction humic substance, endowed with a higher content of phenolic and carboxylic groups, caused an enhanced content of micro- and macro-elements, together with a higher root respiration at lower concentrations (0.5–1 mg C L? 1). The high molecular fraction humic substance, needed higher concentrations (> 5 mg C L? 1) in order to achieve similar effects. This fraction also caused major changes on root morphology. The ability to improve micronutrient assimilation, in particular iron, confirmed the agronomic importance of humic substances on soil fertility. 相似文献

The apoprotein expression and the catalytic activities of cytochrome P450s involved in the biotransformation of xenobiotics were investigated in horse liver microsomes and compared with those of food producing (cattle, pigs, broiler chicks, and rabbits) and laboratory species (rats). Western blot analysis revealed the presence of proteins immunorelated to rat CYP 1A, CYP 2B, CYP 2E, and CYP 3A subfamilies in hepatic microsomes from horses and from any other examined species. With the exception of the N-demethylation of N-nitrosodimethylamine in broiler chicks, all the recorded interspecies differences were quantitative in nature. Equine preparations proved the most active in the biotransformation of the CYP 1A substrates ethoxy- and methoxyresorufin and the least active in the metabolism of aminopyrine and ethoxycoumarin. On a comparative basis, large differences were observed in the rate of the in vitro metabolism of model substrates between "minor" (rabbits, horses) and "major" food producing species. Taken in due consideration the limitations of the in vitro approach, results from this study reinforce the conclusion that studies on drug efficacy and residue depletion should be performed in each target species. 相似文献

To complete a studyaimed at investigating the pattern of the basal activities of liver xenobioticmetabolizing enzymes in major
and minor species intended for meat production, microsomal carboxylesterases and some conjugating enzyme activities were determined
and compared in liver preparations from horses, cattle, pigs, rabbits and broiler chicks, using the rat as a reference species.
Horses and broiler chicks exhibited a lower microsomal carboxylesterase activity towards indophenyl or p-nitrophenyl acetate than that measured in cattle or pig subfractions. Among food-producing species, the rate of glucuronidation
of either 1-naphthol or p-nitrophenol was in the order pigs ∼rabbits > horses >> cattle > broiler chicks. The widest variations were observed in the
acetylation capacity towards p-aminobenzoic acid or isoniazid, which in rabbits was 3-fold to 11-fold greater than that displayed by any other examined
species; low but measurable activities were found in equine and bovine cytosols. The activity of cytosolic glutathione S-transferase
(GST) accepting the general substrate 1-chloro-2,4-dinitrobenzene was significantly higher in rabbits, horses and pigs than
in rat, broiler chicks and cattle. Finally, an uneven pattern of activity towards the other tested GST substrates – 3,4-dichloronitrobenzene,
ethacrinic acid or 1,2-epoxybutane – was observed, possibly reflecting the species-related expression of different GST classes;
in this respect, the conjugative capacity displayed by horses was higher than or comparable to that found in the other food-producing
species. 相似文献

Glucocorticoids are often illegally used in association with anabolic steroids as growth promoters in veal calves and beef production. An experimental administration of dexamethasone was carried out in veal calves in order to assess the role of low doses of exogenous glucocorticoids on induction of thymus atrophy and on the immune response. Three groups of five veal calves each were included in this study: group D was administered 0.4 mg/day of dexamethasone-21-phosphate per os for 25 days; group V was administered 2 mg of dexamethasone-21-isonicotinate i.m. at days 14 and 21, and group K served as control. At slaughter, the weight of the thymus was severely reduced in group D and in group V, compared with control animals. Lesions included severe lymphoid depletion and hyperplasia of adipose tissue. In situ evaluation of apoptosis in thymus, showed a reduction of the percentage of positive nuclear areas of animals belonging to group V in comparison with control animals. An overall decrease of lymphocyte proliferative response was detected after treatment with short acting dexamethasone, while antibody response was not affected by treatments. 相似文献

Occupational transmission of an Orthopoxvirus infection during an outbreak in a colony of Macaca tonkeana in Lazio Region,Italy, 2015 下载免费PDF全文
V. Puro F. M. Fusco C. Castilletti F. Carletti F. Colavita C. Agrati A. Di Caro M. R. Capobianchi G. Ippolito 《Zoonoses and public health》2018,65(5):578-583
Orthopoxviruses spill over from animal reservoirs to accidental hosts, sometimes causing human infections. We describe the surveillance and infection control measures undertaken during an outbreak due to an Orthopoxvirus occurred in January 2015 in a colony of Macaca tonkeana in the province of Rieti, Latio, Italy, which caused a human asymptomatic infection. According to the epidemiological investigation, the human transmission occurred after an unprotected exposure. The contacts among wild, captive and domestic animals and humans, together with decreased immunity against Orthopoxviruses in the community, may put animal handlers at risk of infection, especially after the cessation of smallpox vaccination. To reduce these threats, standard precautions including respiratory hygiene and transmission‐based precautions should be carefully applied also in veterinary medicine. 相似文献
