  text: There are limited data on Lyme borreliosis (LB), a tick-borne disease caused
    by the Borrelia burgdorferi sensu lato complex, in horses. Seropositivity is not
    necessarily associated with clinical disease. Data on seropositivity against Borrelia
    burgdorferi and Anaplasma phagocytophilum in German horses are sparse. Therefore,
    serum samples from horses (n = 123) suspected of having Lyme borreliosis and clinically
    healthy horses (n = 113) from the same stables were tested for specific antibodies
    against Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum. The samples
    were screened for antibodies against Borrelia burgdorferi (ELISA and an IgG line
    immunoblot assay). Furthermore, the samples were examined for antibodies against
    B. burgdorferi and Anaplasma phagocytophilum with a validated rapid in-house test
    (SNAP® 4Dx Plus® ELISA). The clinical signs of suspect horses included lameness
    (n = 36), poor performance (n = 19), and apathy (n = 12). Twenty-three percent
    (n = 26) of suspect horses and 17% (n = 18) of clinically healthy horses were
    seropositive for having a Borrelia burgdorferi sensu lato infection (p = 0.371),
    showing that the detection of specific antibodies against B. burgdorferi alone
    is not sufficient for a diagnosis of equine LB. Anaplasma phagocytophilum seropositivity
    and seropositivity against both pathogens was 20%/6% in suspect horses and 16%/2%
    in the clinically healthy population, showing only minor differences (p = 0.108).
    Unspecific testing for antibodies against B. burgdorferi without clinical suspicion
    of Lyme borreliosis is not recommended since the clinical relevance of seropositivity
    against Borrelia burgdorferi sensu lato remains to be elucidated.

  text: Diet processing impacts on starch properties, such as the degree of starch
    gelatinization. This affects digestibility, as shown in laboratory mice fed either
    a pelleted or an extruded diet. In the present study, the morphology of starch
    particles throughout the digestive tract of mice was visualized. Thirty-two female
    C57BL/6J mice were used for a feeding trial. They were fed a commercial maintenance
    diet for laboratory mice, which was available in pelleted and extruded form, for
    seven weeks. The mice were sacrificed after the feeding period, and chyme samples
    were collected from five sites (stomach, anterior and posterior small intestine,
    caecum, colon). Samples of diets, chyme and faeces were analyzed via stereomicroscopy
    (stained with Lugol’s iodine) and scanning electron microscopy (SEM). The starch
    granules appeared more compact in the pelleted diet, showing first signs of degradation
    only in the small intestine. The caecum content of both diets group was intensively
    stained, particles as well as fluid phase, indicating that it contained mainly
    starch. The SEM pictures of caecum content showed abundant bacteria near starch
    particles. This suggests selective retention of prae-caecally undigested starch
    in the murine caecum, likely the site of microbial fermentation.

  text: Starch gelatinization is a major determinant of carbohydrate digestibility
    and varies with diet processing. Laboratory rodent diets are often marketed as
    identical, but are sold in different forms, regardless of the markedly higher
    starch gelatinization in extruded than in pelleted diets. Our hypothesis was that
    this would impact energy and nutrient digestibility in mice fed pellets or extrudate,
    respectively. Trial 1 showed that feeding C57BL/6 mice a standard maintenance
    diet in extruded form results in a significantly higher digestibility of organic
    matter, energy, and carbohydrates than the identical diet in pelleted form. The
    replication of the experiment, however, revealed a variation between batches of
    the same pelleted diet regarding starch and total dietary fiber contents. Given
    the significant differences in diet digestibility and the potential impacts of
    digestibility on nutrient utilization, the intestinal microbiome, and intermediary
    metabolism, trials performed with differently processed diets are not comparable.
    This might partly explain failures to reproduce results, especially in gastrointestinal
    or microbiome research. Considering this impact on experimental animals, the degree
    of starch gelatinization should be declared in the diet information for laboratory
    animal diets. The differences between batches of laboratory animal diets as observed
    in the pellets are not acceptable.
