Rectal swabs (feacal) samples were collected from 518 sheep across Sokoto state and processed for Campylobacter organisms. Of a total of 518 samples, 93(18.0%) yielded Campylobacter organisms. The Campylobacter species isolated in this study were Campylobacter jejuni, Campylobacter coli, Campylobacter lari and Campylobacter upsaliensis. The most frequently isolated Campylobacter species was C. ...

BACKGROUND The aim of this study was to apply the nested-PCR and bioassay methods in detection and genotyping of Toxoplasma gondii infection in provided sheep aborted fetus samples from Qazvin Province of Iran. METHODS Eighteen sheep aborted fetal samples were studied by nested-PCR-RFLP, histopathological observation and microbiological assay. Bioassay in mice was carried out by inoculating t...

border region of England and Wales, and since recorded world-wide. Prevalence rates in sheep vary from 5% to 50% between countries and from region to region within countries. Clinical signs include barren ewes, abortions, stillbirths and the birth of small weak lambs. Affected lambs can show tremor, abnormal body conformation and hairy fleeces (so-called ‘hairy-shaker’ or ‘fuzzy’ lambs) and the...

the present study was conducted on sixty healthy female domestic ruminants that suffered from still births or abortion, to find sero-positive cases and also to determine the probable role of uterine tissue in diagnosis of akabane viral infection and viral persistency. because of this, a serological test (elisa) and molecular (rt-pcr) diagnostic methods were used to find the seropositive cases a...

Background: Most leptospiral infections in sheep and goat are asymptomatic but may result in high fever, abortion, stillbirth, agalactiae. There is a different foraging behavior between sheep and goat that may cause the different prevalence of Leptospira interrogans infection in sheep and goats. OBJECTIVES: The purpose of the present study was to compare the prevalence of L. interrogans antibod...

Recent research suggests that vertical transmission may play an important role in sustaining Toxoplasma gondii infection in some species. We report here that congenital transmission occurs at consistently high levels in pedigree Charollais and outbred sheep flocks sampled over a 3-year period. Overall rates of transmission per pregnancy determined by PCR based diagnosis, were consistent over ti...

Chlamydia abortus, an important pathogen in a variety of animals, is associated with abortion in sheep. In the present study, 1732 blood samples, collected from Tibetan sheep between June 2013 and April 2014, were examined by the indirect hemagglutination (IHA) test, aiming to evaluate the seroprevalence and risk factors of C. abortus infection in Tibetan sheep. 323 of 1732 (18.65%) samples wer...

Sheep are important to the economy of many countries because they are a source of food for humans. Sheep are commonly infected with the protozoan parasite, Toxoplasma gondii. Infection with the parasite may cause early embryonic death and resorption, fetal death and mummification, abortion, stillbirth, and neonatal death. Severity of infection is associated with the stage of pregnancy at which ...

Colonization of the gallbladder by enteric pathogens such as Salmonella typhi, Listeria monocytogenes, and Campylobacter jejuni is thought to play a key role in transmission and persistence of these important zoonotic agents; however, little is known about the molecular mechanisms that allow for bacterial survival within this harsh environment. Recently, a highly virulent C. jejuni sheep aborti...

Nigeria showed that optimal and weight 1st young ewes was not less than eleven months least 13kg respectively When mated earlier, incidence abortion in­creased lambs tended to smaller birth. In older ages lengthening generation internal unacceptable. The relalionuship between (4 ) (X) from four 56 weeks est...
