Abstract: Twin birth is a complex condition observed in most livestock animals, when the female gives birth to two or more offspring, generally out of the same mating. In cattle, it is a rare condition (3 to 5%) and depends on the genetic background and environmental factors. Twin birth is a result of multiple ovulations, being more common in dairy rather than in beef cattle. Calves could be monozygous or dizygous, with the same or of different sexes. When twins are born with different sexes, a sexual condition called Freemartinism occurs in between 90 to 97% of pregnancies, causing infertility in the female calf. Knowing that the twin rate is rare in commercial beef cattle, here we present an even rarer case of twin birth from two different sires after natural mating, also called heteropaternal superfecundation. |

A new arbuscular mycorrhizal fungus, Cetraspora helvetica, was found in three Swiss agricultural soils: a no-till crop production system and two temporary grasslands. It forms white spores, 210?270 µm diam, on dark yellow sporogenous cells. The spores have three walls: a triple-layered outer, a bi-layered middle and a triple-layered inner wall. The spore surface is crowded with convex warts, 5?12 µm diam at the base and 1.5?5.0 µm high. The germination shield is hyaline with multiple (6?10) lobes. Glomerospores of two other Gigasporineae spp. have also three walls, multiple-lobed hyaline germination shields, and projections on the outer spore surface: C. spinosissima and C. striata. However, spores of these fungi are substantially pigmented (ochraceous yellow to rust) and crowded with short, thin spines or fingerprint-like processes, respectively. Partial sequences of the 28S ribosomal gene place the new species adjacent to C. spinosissima, C. pellucida, and C. gilmorei. Phylogenetic analyses demonstrate the monophyly of the two genera Racocetra and Cetraspora within the Racocetraceae. |
