N. caninum could cause abortion in small ruminants. The aim of the study was to detect N. caninum infection in ovine aborted foetuses in the Mashhad area by PCR examination. During the period 2009 to 2013, 71 ovine aborted foetuses were collected and their brain samples examined by PCR. Of the 71 brains of the aborted foetuses, N. caninum DNA was detected in seven (9.8%) samples. In conclusion,...

The facultative intracellular Gram-negative bacterium Brucella melitensis causes brucellosis in domestic and wild mammals, and it is a dominant pathogen responsible for human disease. This study reports the whole-genome sequencing of B. melitensis strain QY1, isolated from sheep suffering from abortion and arthritis in 2015 in Gansu, China.

We report the complete and annotated genome sequence of the animal pathogen Listeria ivanovii subsp. ivanovii strain PAM 55 (serotype 5), isolated in 1997 in Spain from an outbreak of abortion in sheep. The sequence and its analysis are available at an interactive genome browser at the Institut Pasteur (http://genolist.pasteur.fr/LivaList/).

The obligate intracellular Gram-negative bacterium Chlamydia abortus is one of the causative agents of abortion and fetal loss in sheep, goats, and cattle in many countries. It also affects the reproductivity of yaks (Bos grunniens). This study reports the whole-genome sequence of Chlamydia abortus strain GN6, which was isolated from aborted yak fetus in Qinghai-Tibetan Plateau, China.

Four experiments were conducted to determine the effect of feeding dried pine needles (Pinus ponderosa; PN) on the abortion rate of ruminants. In Exp. 1, cattle were fed 5.4 kg of PN daily for 21 d starting at 116, 167, 215, or 254 d of pregnancy. The PN did not cause abortions when started at 116 d; thereafter, the percentage of cows that aborted increased linearly, and the interval to abortio...

Bovine genital campylobacteriosis (BGC) is a true venereal disease of cattle. This disease results in infertility, embryonic and fetal death, metritis, salpingitis, pyometra, and abortion in cattle, and sheep and goats as well. The causal agent of BGC, is Campylobacter fetus. This organism is found worldwide and causes significant economic losses in endemic areas where appropriate management ha...

An outbreak of leptospirosis in sheep is recorded as the first epidemic of ovine leptospirosis in Egypt. The sick animals showed typical symptoms such as fever, jaundice, red urine and abortion, with a fatal course. Acute and convalescent sera were tested for demonstration of seroconversion using the microscopic agglutination testto confirm infection. Long-acting tetracycline was successfully u...

Aim: The aim of present study was to determine the seroprevalence of Neospora caninum infection in aborted sheep population from Hamedan province of Iran. Materials and Methods: 358 serum samples of aborted ewes were evaluated for IgG-antibodies to N. caninum using enzymelinked immunosorbent assay (ELISA). Results: 8 samples (2.2%) were found seropositive for this infection (2.05< Confidence in...

Dexamethasone is widely used in both veterinary and human medical practices. However, it seems to cause some deleterious effects on pregnancy probably by causing changes in the reproductive hormone levels and their corresponding receptor concentrations. This study investigated the effects of dexamethasone on these parameters. Twenty healthy adult Yankasa sheep comprising 18 ewes and 2 rams were...

Rift Valley fever (RVF) is a peracute or acute zoonotic disease of domestic ruminants. The virus is currently confined to the African continent and Arabian Peninsula. It is caused by a single serotype of a mosquito-borne virus of the Bunyaviridae family (genus Phlebovirus). The disease occurs in climatic conditions favouring the breeding of mosquito vectors and is characterised by abortion, neo...
