Abstract:
An outbreak of chlamydiosis in farmed Indopacific crocodiles (Crocodylus porosus) : clinical communication
F.W. Huchzermeyer,E. Langelet,J.F. Putterill
Journal of the South African Veterinary Association , 2012, DOI: 10.4102/jsava.v79i2.253
Abstract: An outbreak of chlamydiosis was diagnosed in hatchling and juvenile Indopacific crocodiles (Crocodylus porosus) on a crocodile farm in Papua New Guinea. The outbreak was characterised by high mortality with hepatitis and exudative conjunctivitis. The agent appears to have been introduced with live wild-caught crocodiles, which are purchased routinely by the farm. Improved quarantine procedures and treatment with tetracycline led to a rapid reduction of losses on the farm.

Identification and partial sequencing of a crocodile poxvirus associated with deeply penetrating skin lesions in farmed Nile crocodiles, Crocodylus niloticus
F.W. Huchzermeyer,D.B. Wallace,J.F. Putterill,G.H. Gerdes
Onderstepoort Journal of Veterinary Research , 2010, DOI: 10.4102/ojvr.v76i3.35
Abstract: When large numbers of crocodile skins were downgraded because of the presence of small pin pricklike holes, collapsed epidermal cysts were found deep in the dermis of juvenile crocodiles while forming cysts were observed in hatchlings. Histopathology of these forming cysts showed the presence of intracytoplasmic inclusions in proliferating and ballooning epidermal cells. Pox virions were seen in electron microscope preparations made from the scabs of such early lesions. The partial sequencing of virus material from scrapings of these lesions and comparison of it with the published sequence of crocodile poxvirus showed the virus associated with the deep lesions to be closely related, but different. To differentiate between the two forms of crocodile pox infection it is suggested that the previously known form should be called ''classical crocodile pox'' and the newly discovered form ''atypical crocodile pox''. The application of strict hygiene measures brought about a decline in the percentage of downgraded skins.
Vascular changes after cardiopulmonary bypass and ischemic cardiac arrest: roles of nitric oxide synthase and cyclooxygenase
Sellke, F.W.;
Brazilian Journal of Medical and Biological Research , 1999, DOI: 10.1590/S0100-879X1999001100004
Abstract: cardiac surgery involving ischemic arrest and extracorporeal circulation is often associated with alterations in vascular reactivity and permeability due to changes in the expression and activity of isoforms of nitric oxide synthase and cyclooxygenase. these inflammatory changes may manifest as systemic hypotension, coronary spasm or contraction, myocardial failure, and dysfunction of the lungs, gut, brain and other organs. in addition, endothelial dysfunction may increase the occurrence of late cardiac events such as graft thrombosis and myocardial infarction. these vascular changes may lead to increased mortality and morbidity and markedly lengthen the time of hospitalization and cost of cardiac surgery. developing a better understanding of the vascular changes operating through nitric oxide synthase and cyclooxygenase may improve the care and help decrease the cost of cardiovascular operations.
Biology of the Vespine Wasps
F.W. Gess
African Zoology , 2012,
Abstract: The Vespinae, some members of which are commonly known as hornets and others as yellow jackets, are morphologically the most specialized of the Vespidae and have evolved social lives amongst the most highly developed in this family. The book under review is the first comprehensive account of the biology of the vespine wasps, with special emphasis on behavioural aspects. The authors, Makoto Matsuura, an ecoethologist, and Seiki Yamane, a systematist with wide experience in ecology and ethology, are based in Japan at Mie and Kagoshima Universities respectively.
Gender, Age and Reproductive Status Effects on Serum Prolactin Concentrations in Different Varieties and Species of Poultry
F.W. Edens
International Journal of Poultry Science , 2011,
Abstract: Homologous chicken prolactin (chPRL) and turkey prolactin (trPRL) radioimmunoassays were used to assess the effects of gender, age and reproductive status on serum prolactin concentrations in several varieties and species of poultry. Adult males (chickens, turkeys [domestic and wild], Coturnix quail and chukar partridges had lower serum prolactin (PRL) concentrations than did their female counterparts. Aging in meat-type female chickens appeared to be associated with increasing PRL concentrations, but aging of White Leghorn chickens did not result in increased serum prolactin concentrations. Aging in males did not alter serum prolactin concentrations. In female chukar partridges, serum prolactin concentrations were similar to that of White Leghorn hens and male chukar serum prolactin concentrations were similar to levels found in male chickens. Serum prolactin concentrations in Coturnix males and females, with females having greater serum prolactin than males, were generally higher than in males and females of other fowl involved in this study. Broodiness was associated with greatly elevated serum prolactin concentrations. The serum prolactin concentrations derived from the use of the chPRL assay as a heterologous assay for chukar and domestic and wild turkeys, yielded results that were lower but in parallel with results from trPRL assay. The homologous chicken PRL radioimmunoassay appeared to be useful as a heterologous assay for domestic and wild turkey and for chukar partridge PRL.
