Capillariasis in the domestic fowl in New Zealand

Abstract

Extract

With the increase in more intensive methods of poultry production in recent years, worms of the genus Capillaria Zeder 1800 (hairworms) have become an important factor contributing to disease in chickens and turkeys. Apart from causing death, they are also responsible for lower growth rates, decreased egg production, and decreased fertility of the flock (Platt and Schwabe, 1958 Platt, C. S. and Schwabe, O. 1958.

Helminth., 112: 191–200.  [Google Scholar]), Unfortunately, these parasites have been relatively neglected in research and survey work. Far more interest has been devoted to the more obvious nematode parasites of poultry, such as Ascaridia galli and Heterakis gallinarum. This can, in part, be explained by the facts that Capillaria spp. are difficult to work with, they are not easily detectable and infections are difficult to establish under experimental conditions.  相似文献   

Coccidiosis of the fowl in New Zealand     

R. Pohl Dr.med.vet. 《New Zealand veterinary journal》2013,61(12):249-250

Extract

Coccidiosis of the fowl is generally recognized in New Zealand as a ubiquitous, economically important disease, but there is little published information on the incidence of the various species of coccidia causing disease.  相似文献   

Effects of melatonin and progesterone administered to ewes in spring and summer     

J E Wheaton  H A Pohl  H F Windels 《Journal of animal science》1990,68(4):923-930

Melatonin (MEL) was evaluated for effects on LH, prolactin (PRL) and fertility in spring (Exp. 1, 2) and summer (Exp. 3 to 5). In Exp. 1, 17 ovariectomized ewes bearing estradiol implants were fed 3 mg MEL or vehicle for 44 d beginning May 1. Melatonin decreased (P less than .001) PRL levels but had no effect on LH secretion and response to GnRH. In Exp. 2, 12 ewes each received a 40-d MEL ear implant or a sham implant on March 31. Progesterone-releasing pessaries (CIDR) were applied for 12 d and were withdrawn concomitant with ram joining on May 7. Neither treatment stimulated follicular development or induced estrus or ovulation. Exp. 3 and 4 were contemporary 2 x 2 factorial trials with 24 ewes at each of two locations. Melatonin implants were administered on June 29 and CIDR on July 22. The CIDR were removed and rams (Exp. 3, vasectomized; Exp. 4, fertile) were joined on August 3. Days from introduction of rams to estrus were reduced (P less than .05) by CIDR but not by MEL. All ewes lambed in Exp. 4, and days to estrus and conception were reduced (P less than .001) by CIDR but not by MEL. Exp. 5 was designed like Exp. 4 except that MEL implants were inserted June 20 and rams were joined August 8. Intervals from introduction of rams to estrus were reduced (P less than .01) by both MEL and CIDR treatments.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Comparison of necrotoxigenic Escherichia coli isolates from farm animals and from humans     

Mainil JG  Jacquemin E  Pohl P  Fairbrother JM  Ansuini A  Le Bouguénec C  Ball HJ  De Rycke J  Oswald E 《Veterinary microbiology》1999,70(1-2):123-135

Necrotoxigenic Escherichia coli (NTEC) isolated from animals and humans can belong to the same serogroups/types and produce or carry the genes coding for fimbrial and afimbrial adhesins of the same family, P, S, F17, and/or AFA, raising the question of a potential zoonotic source of human infection. The main purpose of this study was to compare 239 NTEC1 strains (45 from cattle, 65 from humans and 129 from piglets) and 98 NTEC2 strains from cattle, using a uniform and standardized typing scheme. The O serogroups and the biotypes recognized amongst NTEC1 and NTEC2 strains were quite varied, although some were more frequently observed (serogroups O2, O4, O6, O8, O18, O78, and O83 and biotypes 1, 2, 5, 6, and 9). Hybridization, results with gene probes for the P family (PAP probe), S family (SFA probe), AFA family (AFA probe), F17 family (F17 probe) of fimbrial and afimbrial adhesins, could differentiate most NTEC1 strains, which are PAP-, SFA- and/or AFA-positive, from NTEC2 strains, which are mainly F17- and/or AFA-positive, but were of no help in differentiating between NTEC1 strains from cattle, humans, and piglets. All but seven (98%) NTEC1 and NTEC2 strains were serum resistant, 199 (59%) produced an aerobactin, and colicin (I, V, or unidentified) was produced by 22-34% of them. On the other hand, more than 90% of the NTEC1 strains were haemolytic on sheep blood agar compared with only 40% of the NTEC2 strains. Production of a classical haemolysin, active on sheep erythrocytes, and hybridization with the PAP probe were associated in a majority of NTEC1 strains (63-81%), but very rarely in NTEC2 strains (3%). Production of enterohaemolysin and hybridization with the PAP probe were much less frequently associated in NTEC strains (1-9%). It was thus possible neither to completely differentiate NTEC1 strains from cattle, humans, and pigs, nor to define a signature for the NTEC strains. Necrotoxigenic E. coli must still be identified on the basis of the production of the Cytotoxic Necrotizing Factors 1 or 2 (or of their encoding genes) and complete differentiation of NTEC1 strains from cattle, humans, and piglets, use additionnal methods.  相似文献

Quantum information storage for over 180 s using donor spins in a 28Si "semiconductor vacuum"     

Steger M  Saeedi K  Thewalt ML  Morton JJ  Riemann H  Abrosimov NV  Becker P  Pohl HJ 《Science (New York, N.Y.)》2012,336(6086):1280-1283

A quantum computer requires systems that are isolated from their environment, but can be integrated into devices, and whose states can be measured with high accuracy. Nuclear spins in solids promise long coherence lifetimes, but they are difficult to initialize into known states and to detect with high sensitivity. We show how the distinctive optical properties of enriched (28)Si enable the use of hyperfine-resolved optical transitions, as previously applied to great effect for isolated atoms and ions in vacuum. Together with efficient Auger photoionization, these resolved hyperfine transitions permit rapid nuclear hyperpolarization and electrical spin-readout. We combine these techniques to detect nuclear magnetic resonance from dilute (31)P in the purest available sample of (28)Si, at concentrations inaccessible to conventional measurements, measuring a solid-state coherence time of over 180 seconds.  相似文献
