Sub-cycle pulse revealed with carrier-envelope phase control of soliton self-compression in anti-resonant hollow-core fiber.

The influence of the carrier-envelope phase (CEP) of a pump pulse on the multioctave supercontinuum (SC) generation in a gas-filled anti-resonant hollow-core fiber (AR HCF) by soliton self-compression (SSC) has been explored. We have shown an octave-wide third harmonic generation (THG) in the visible-to-near-infrared range during the pulse compression down to a sub-cycle duration. The CEP of a multi-cycle pump pulse provides control of interference between the third harmonic (TH) and the SC that indicates the coherent synthesis of a sub-cycle pulse with a duration of about 0.

Neospora-related abortions in sheep in Israel - A serological diagnostic challenge in an endemic area.

Abortions in sheep flocks is a common multifactorial problem, which affects animal productivity and welfare. Israel is endemic to several infectious abortifacient pathogens, with neosporosis identified as a prominent cause. High seroprevalence of N.

The involvement of protozoan parasites in sheep abortions - A ten-year review of diagnostic results.

Abortions in sheep flocks affect animal health and lead to significant losses in productivity, with severe economic consequences. In recent years, the role of protozoan parasites as the cause of ovine abortions has been significant. Here, the diagnosis of infectious causes of abortions in sheep in Israel in the last decade is reviewed, focusing on parasitic pathogens.

The Effect of Vaccination with Live-Frozen Tachyzoites on Abortion Rates of Naturally Infected Pregnant Cows.

Neosporosis is a major cause of abortions in cattle worldwide. Recently a live attenuated vaccine showing promising results in preventing abortions, when administered at mid-pregnancy to seropositive cows, was developed. In this study, vaccination with 2 × 10 live frozen tachyzoites (NcIs491) was used to immunize naturally infected seropositive pregnant dairy dams.

Serological and Molecular Prevalence of in Apparently Healthy Horses in Israel.

is a tick-borne hemoparasite of equines and one of the causative agents of equine piroplasmosis, which poses a great concern for the equine industry regarding animal welfare and international horse movement. The parasite is endemic in Israel; however, its seroprevalence in the area was never evaluated due to antigenic heterogenicity in the gene used in the commercially available kit. Blood samples were collected from 257 horses at 19 farms throughout the country and screened for the presence of anti- antibodies via an indirect immunofluorescent antibody test (IFAT) and for the presence of parasite DNA by nested PCR.
