A study is described which is unique in that resistance to each of the major diseases which affect production in Merino sheep was measured in the same flock under the same environmental conditions. Results indicated that within the one flock, genetic variation exists for resistance to internal parasites, foot-rot, fleece rot and dermatophilosis. Heritability estimates were similar to those publ...

There is evidence of antigenic diversity and of differences in virulence in Dermatophilus congolensis. For the understanding of the epidemiology of dermatophilosis it is important to distinguish between strains of the organism. Twenty field isolates from cattle in Chad and Cameroon, and an American reference strain, have been examined on restriction fragment length polymorphisms. After restrict...

Random peptide libraries (RPL) displayed on the surface of filamentous bacteriophages have been extensively used as a tool to map epitopes or to identify antigenic mimics (mimotpoes) of diseasespecific monoclonal antibodies or polyclonal sera. These RPL are engineered by the insertion of degenerate oligonucleotides, encoding a specific number of random amino acids, in frame with a bacteriophage...

BACKGROUND Bovine dermatophilosis, an important skin disease of cattle caused by Dermatophilus congolensis, negatively impacts the livelihoods of small-holder farmers in Zimbabwe. This impact is through, morbidity, loss of draught animal power, costs incurred to manage the disease, losses associated with devalued damaged hides and the resultant culling of some of the affected cattle. Due to the...

This study was designed to assess the influence of disease-inducing agents other than Dermatophilus congolensis on incidence bovine dermatophilosis from cattle farms in Federal University Agriculture, Abeokuta and Olabisi Onabanjo University, Ogun State also Akinyele market Oyo State. Skin scrapings collected with typical lesions were examined for presence bacteria, fungi ectoparasites. Out 57 ...

skin lesions were found in two 3–4-year-old holstein cows in a dairy farm in shiraz. lesions were distributed mostly around the neck, forelimbs, hindlimbs, and bilateral of midline portion and varied from nodule-like structure to patch with extensive accumulation of crust. skin scraping samples were taken from each animal and direct smears were prepared, stained with giemsa and observed under a...

dermatophilosis is a bacterial skin infection and wet conditions like, raining and dipping predispose sheep to it. a great economic loss can be caused by this disease because of its effect on the quality of wool. in iran (near saveh), there was an outbreak of the disease in a herd and the clinical manifestation was different from that of typical dermatophilosis. diffuse wide alopecic area accom...

In this study, the authors evaluated parenteral treatment of zebu cattle, with naturally and experimentally induced bovine dermatophilosis, in western Sudan, using four different antibiotic treatments. In terms of recovery rate, weight gain, avoiding relapse and preventing death, gentamycin was found to be the most effective treatment, followed by a combination of penicillin and streptomycin an...

Blowfly strike and the methods used to combat blowfly strike were recorded on 33 properties in the Rûens area of South Africa during 2003/2004. Data were recorded on Merino and Dohne Merino hoggets (n = 4951) with at least 3 months' wool growth. The following data were captured: presence or absence of strike, site of the strike (body or breech), presence or absence of dermatophilosis as well as...
