[Ab] Resumo:Management of many North American forests is challenged by the need to balance the potentially competing objectives of reducing risks posed by high-severity wildfires and protecting threatened species. In the Sierra Nevada, California, concern about high-severity fires has increased in recent decades but uncertainty exists over the effects of fuel-reduction treatments on species associated with older forests, such as the California Spotted Owl (Strix occidentalis occidentalis). Here, we assessed the effects of forest conditions, fuel reductions, and wildfire on a declining population of Spotted Owls in the central Sierra Nevada using 20 years of demographic data collected at 74 Spotted Owl territories. Adult survival and territory colonization probabilities were relatively high, while territory extinction probability was relatively low, especially in territories that had relatively large amounts of high canopy cover (≥70%) forest. Reproduction was negatively associated with the area of medium-intensity timber harvests characteristic of proposed fuel treatments. Our results also suggested that the amount of edge between older forests and shrub/sapling vegetation and increased habitat heterogeneity may positively influence demographic rates of Spotted Owls. Finally, high-severity fire negatively influenced the probability of territory colonization. Despite correlations between owl demographic rates and several habitat variables, life stage simulation (sensitivity) analyses indicated that the amount of forest with high canopy cover was the primary driver of population growth and equilibrium occupancy at the scale of individual territories. Greater than 90% of medium-intensity harvests converted high-canopy-cover forests into lower-canopy-cover vegetation classes, suggesting that landscape-scale fuel treatments in such stands could have short-term negative impacts on populations of California Spotted Owls. Moreover, high-canopy-cover forests declined by an average of 7.4% across territories during our study, suggesting that habitat loss could have contributed to declines in abundance and territory occupancy. We recommend that managers consider the existing amount and spatial distribution of high-canopy forest before implementing fuel treatments within an owl territory, and that treatments be accompanied by a rigorous monitoring program.

[Ab] Resumo:Background: Risk factors for human infection with highly pathogenic (HP) and low-pathogenic (LP) avian influenza (AI) H5N2 and H7N1 were investigated during outbreaks in ostriches in the Western Cape province, South Africa. Methods: Serum surveys were conducted for veterinarians, farmworkers, and laboratory and abattoir workers involved in 2 AI outbreaks in the Western Cape province: (1) controlling and culling of 42000 ostriches during (HPAI)H5N2 outbreaks in ostriches (2011) (n = 207); (2) movement control during (LPAI)H7N1 outbreaks in 2012 (n = 66). A third serosurvey was conducted on state veterinarians from across the country in 2012 tasked with disease control in general (n = 37). Antibodies to H5 and H7 were measured by means of hemagglutination inhibition and microneutralization assays, with microneutralization assay titers >40 considered positive. Results: Two of 207 (1%) participants were seropositive for H5 and 4 of 207 (2%) for H7 in 2011, compared with 1 of 66 (1.5%) and 8 of 66 (13%) in 2012. Although individuals in all professions tested seropositive, abattoir workers (10 of 97; 10.3%) were significantly more at risk of influenza A(H7N1) infection (P = .001) than those in other professions (2 of 171;1.2%). Among state veterinarians, 4 of 37(11%) were seropositive for H7 and 1 of 37 (2.7%) for H5. Investigations of (LP)H7N1-associated fatalities in wild birds and quarantined exotic birds in Gauteng, AI outbreaks in poultry in KwaZulu-Natal, and ostriches in Western Cape province provide possible exposure events. Conclusion: (LPAI)H7N1 strains pose a greater infection-risk than (HPAI)H5N2 strains to persons involved in control of outbreaks in infected birds, with ostrich abattoir workers at highest risk.

[Ti] Título:Adsorption of Hg(II) and Pb(II) ions by nanoscale zero valent iron supported on ostrich bone ash in a fixed-bed column system.

[Ab] Resumo:In this research, ostrich bone ash (OBA) was modified with nanoscale zerovalent iron (nZVI) particles and applied as a novel composite adsorbent (OBA/nZVI) for dynamic adsorption/reduction of Hg(II) and Pb(II) ions in a fixed-bed column system. Entrapment of nZVI in OBA beads barricades the particles from oxidation and aggregation. The dynamic behavior of metal ions removal by OBA/nZVI was assessed as a function of inlet flow rates, bed height, initial pollutants concentration and pH. The synthesized OBA/nZVI composite was characterized by several physicochemical techniques. Increase in pH and bed height and decrease in flow rates and initial metal concentration resulted in delay of breakthrough time. OBA breakthrough profile is sharper than the OBA/nZVI breakthrough curve for both metal ions and the breakthrough times increase in the order OBA/nZVI-Hg(II) > OBA/nZVI-Pb(II) > OBA-Pb(II) > OBA-Hg(II). Based on the experiment results, redox reaction is expected to occur to a certain extent, as the standard reduction potentials of Hg(II) and Pb(II) are more than that of Fe(II). From a practical point of view, the OBA/nZVI could be applied as a material to remove Hg(II) and Pb(II) ions from natural surface and ground water with a pH value of 5-9.

[Ab] Resumo:A retrospective study was carried out to define the spectrum of spontaneous diseases in ostriches and few other captive ratites, order Struthioniformes, in northwestern Germany. The investigation included 71 ratites necropsied between 1968 and 2014. They consisted of 54 ostriches, 5 emus, and 12 rheas with 37 adults, 23 juveniles and 11 neonates and embryonated eggs. Necropsy reports were reviewed, histologic preparations were re-examined and additional histochemical and immunohistochemical stains were carried out in selected cases. In many animals more than one morphologic diagnosis attributable to different disease processes was found. In adult animals (n = 37), the most commonly altered organ systems were the musculoskeletal system (49%), the digestive system (46%), and the cardiovascular system (46%) affected by traumatic lesions, inflammatory and degenerative changes, respectively. A spongy degeneration was found in the brain (35%); however, immunohistochemistry and western blotting failed to detect pathological prion protein. In juvenile animals (n = 23), the musculoskeletal (44%) and the digestive system (43%) were mainly affected by traumatic and inflammatory lesions, respectively. In embryonated eggs and neonates (n = 11) the major cause of death was circulatory failure associated with generalized subcutaneous edema as described for improper incubation conditions (64%). Summarized, most of the findings observed in adult and juvenile ratites in northwestern Germany are related to trauma, inflammatory and degenerative disorders, whereas death in embryonated eggs and neonates was most likely related to breeding conditions. A spongy encephalopathy awaits further studies to elucidate cause and pathogenesis.

[Ab] Resumo:Ancient DNA (aDNA) analysis of extinct ratite species is of considerable interest as it provides important insights into their origin, evolution, paleogeographical distribution and vicariant speciation in congruence with continental drift theory. In this study, DNA hotspots were detected in fossilized eggshell fragments of ratites (dated ≥25000 years B.P. by radiocarbon dating) using confocal laser scanning microscopy (CLSM). DNA was isolated from five eggshell fragments and a 43 base pair (bp) sequence of a 16S rRNA mitochondrial-conserved region was successfully amplified and sequenced from one of the samples. Phylogenetic analysis of the DNA sequence revealed a 92% identity of the fossil eggshells to Struthio camelus and their position basal to other palaeognaths, consistent with the vicariant speciation model. Our study provides the first molecular evidence for the presence of ostriches in India, complementing the continental drift theory of biogeographical movement of ostriches in India, and opening up a new window into the evolutionary history of ratites.

[Ab] Resumo:Ostrich farming is an important livestock industry in different world regions with a diverse offer of products and services. In Colombia, as in other countries, this market led the importation of animals from countries like Canada, United States of America and South Africa for breeding objectives. With the animals, specific pathogens for these ratites could be introduced. Libyostrongylus spp. is a strongylid nematode with worldwide distribution, which can induce a severe disease and mortality in infected animals. Limited studies in Colombia have identified parasites in ostrich farming systems. The aim of this study was to identify parasites of the genus Libyostrongylus to a species level in faecal samples from ostrich farms in three departments of Colombia. Five ostrich farms from Boyacá, Meta and Tolima were sampled in 2011 and in 2013 to obtain fresh faecal samples which were further processed by flotation tests for egg visualization and faecal culture for infective larvae identification by morphological and morphometric parameters. One from the five farms, located in Meta department, was positive for strongylid eggs in both sampling periods. After faecal culture, infective larvae were identified as Libyostrongylus douglassii. These results corroborate previous records of Libyostrongylus in ostrich farms from Meta and confirms, for the first time, infection by L. douglassii in ratites from this region. Further studies must identify associated determinants for infection and its effects on the flock health and production.

[Ti] Título:Effect of lantibiotic gallidermin against biogenic amine-producing faecal staphylococci from ostriches and pheasants.

[Ab] Resumo:In ostriches and pheasants, there is still limited information relating to staphylococci and their properties. Biogenic amines (BAs) are nitrogenous low-molecular-weight substances with biological functions in animals, plants and microorganisms. In this study, we focused on BA production by targeted faecal staphylococci from ostriches and pheasants and their sensitivity to lantibiotic bacteriocin gallidermin. Gallidermin belongs in a group of polycyclic proteinaceous antimicrobial substances. Thirty-six faecal staphylococci (24 strains from 140 ostriches, 12 from 60 pheasants) comprising different species were tested. Staphylococci from ostriches and pheasants did not produce tryptamine-TRYP, putrescine-PUT, cadaverine-CAD or histamine-HIS. Production of tyramine-TYM, phenylethylamine-PEA was high or very high (100-1000 mg/L). Production of spermine-SPM and spermidine-SPD by staphylococci was very low or low although in the case of staphylococci from pheasants medium production of SPM was found. Because of the risk posed by BAs for consumers, the control of BA-producing bacteria is important from the points of view not only of safety assessment of food-producing animals but also of human health safety. The sensitivity to gallidermin in biogenic amine-producing staphylococci from ostriches and pheasants detected here is the most promising indication for further application of gallidermin for veterinary purposes. The novelty of our study lies in testing the ability of faecal staphylococci from ostriches and pheasants to produce BAs and in their treatment with gallidermin which has so far not been tested in this way.

[Ab] Resumo:1. Hatching success of ostrich eggs is poor (50-60% of fertile eggs). The current study was designed to identify the timing of key stages in the development of the ostrich embryo. 2. Growth of both embryo and wing length during 42 d of incubation was comparable and approximately linear, with a more or less weekly doubling in size up to 35 d of incubation. 3. The embryo eye size increased more rapidly than beak length and reached a maximum of ~16.2 mm by 28 d of incubation, whereas beak length increased continuously until hatching at 42 d. 4. Linear regression equations were derived from morphometric measurements of embryos between 7 and 42 d. 5. Information stemming from these results can be used to estimate the age of dead-in-shell embryos in an attempt to identify timing of incubation problems that potentially result in low hatchability of fertile eggs.

[Ti] Título:Effect of climate region and stocking density on ostrich (Struthio camelus) productive performances.

[Ab] Resumo:The effects of three climates (hot and dry, mild and humid and Alpine) and three flock densities (<100, 100-300 and >300 m ) on ostrich reproductive and productive traits were studied. Data were compared with the benchmark target sets by the World Ostrich Association (Ostrich benchmark Performance Targets. Version 2, May, 2008) for reproductive qualifications of ostrich. No significant difference was observed on egg production, weight, fertility, hatchability and day-old chicks weight among the three climate conditions; however, the Alpine climate had a lower performance trend. Mild and humid climates had a significant effect of age at sexual maturity for both males and females as well as on the duration of egg production season. Stocking density did not show significant difference on egg production, hatchability, age of male and female at sexual maturity and on duration of egg production season, while an area >300 m showed a reduction in egg weight and day-old chick weight. Further, an area <100 m led to a weaker ostrich fertility rate. Results showed that the ostrich would have a better performance under hot and dry and mild and humid climates as compared to Alpine climate with a stocking density of 100-300 m area per breeder bird. Thus, climatic intervention strategies at Alpine regions may be carried out for maintaining optimal reproductive qualification of ostrich so as to improve the productivity in this sector.

[Ab] Resumo:Forty-three fowl adenovirus (FAdV) strains were isolated in China from 2007 to 2014 from poultry and ostriches with inclusion body hepatitis (IBH) and hydropericardium syndrome (HPS). Phylogenetic analysis showed that 28/43 strains clustered into Fowl aviadenovirus D (FAdV-D) and 9/43 strains clustered into FAdV-E. FAdV-C included three isolates of ostrich origin, one of goose origin and two of chicken origin. Based on hexon loop 1 gene sequencing analysis, these viruses were genetically related to FAdV-4, FAdV-8a, FAdV-8b and FAdV-11, of which FAdV-11 was dominant. The isolation in 2014 of three FAdV strains belonging to serotype 4 from ostrich flocks is to our knowledge the first finding of FAdV-4 infection and HPS cases in ostriches. Epidemiological analysis showed that FAdV has been circulating in northern and eastern China, where more than 50% of layers and broilers are raised. The hosts of this pathogen included broilers, layers, geese and ostriches. IBH and HPS cases had a sporadic or cluster distribution from 2007 to 2013; however, since 2014 the number of cases has increased sharply. To control FAdV, strict biosecurity protection measures are necessary and a multivalent vaccine may be needed.
