In general, 50 % and 100 % of piglets born to resistant (RR) sows crossed with hetero- or homozygous susceptible (SR, SS) boars, respectively, are susceptible but do not receive colostral antibodies against F4 fimbriae unless the sows have been vaccinated. The question arises as to whether resistant sows produce protective amounts of F4 antifimbrial antibodies after vaccination. The serum and colostrum antibody titres of 12 resistant and 12 susceptible vaccinated gilts were compared. The effect of the receptor status of the dam and sire on the preweaning performance of 5027 piglets was evaluated using Agroscope's recordings. The sows of the experimental herd, where ETEC F4 was circulating, were vaccinated against ETEC twice during the first pregnancy and once during each following pregnancy. The log2 transformed F4 antibody titres in the serum obtained after the second vaccine injection as well as in the colostrum of the 12 resistant animals were lower than the titres of the susceptible animals (serum: F4ab 11,19 ± 1,44 vs. 12,18 ± 1,33, P = 0,096; F4ac 10,03 ± 1,58 vs. 11,59 ± 1,43, P = 0,019; colostrum: F4ab 12,20 ± 2,41 vs. 14,02 ± 1,31, P = 0,033; F4ac 10,93 ± 2,46 vs. 13,03 ± 5,21, P = 0,006).

The aim of this cross-sectional study was to determine the prevalence of D. nodosus in western Austria both at animal and farm levels. Real-time PCR was evaluated in comparison with clinical and bacteriological investigations from interdigital foot swabs to detect D. nodosus-infected animals. In addition, the use of pooled four-foot swabs to detect foot rot was determined. In course of the study a total of 3156 sheep from 124 farms were examined for lameness and clinical signs of foot rot. The found flock prevalence of D. nodosus was 30,65 % with bacterial culture showing a sensitivity of 75,0 % and a specificity of 100,0 % (p < 0,001) respectively, compared with PCR. Furthermore, clinical foot rot scores (Ckorr = 0,87; p < 0,001) and lameness scores (Ckorr = 0,71; p < 0,001) highly correlated with the detection of D. nodosus by PCR. The result showed that the clinical examination can be used to identify animals infected with D. nodosus in flocks, but PCR must be used to confirm the diagnosis. D. nodosus could be detected equally well with risk-based pools-of-five samples as with undiluted samples (p < 0,001), suggesting that a pool-of-five samples might be a suitable and cost-effective method for detecting D. nodosus in sheep flocks. This study provides an overview of foot rot in Tyrolean sheep flocks and outlines the possibilities and limitations of the various diagnostic tools for D. nodosus.

Brainstem dysfunction is induced by intracranial hypotension. BAER was used in horses with colic surgery which had a low arterial blood pressure during general anesthesia. The endoscopic finding of the guttural pouch was the ipsilateral mild to severe hypertrophy of the tympanostylohyoideum in horses with external otitis or head trauma. The otoscopic examination of standing sedated horses was done before BAER. The cartilagineous and osseous part of the external ear canal in horses with external otitis were obstructed with exsudate and tympanic membranes were not visible. Horses with right sided external otitis: right moderate to severe conductive hearing loss (significantly prolonged latencies of I, III, V and interpeak latencies I-III, I-V, III-V; thresholds of hearing levels 60 to 80 dB right); horses with left sided external otitis: left severe conductive hearing loss (no correct identification of BAER peaks, latencies not measurable, 80 dB); horse with left sided head trauma: severe left sided conductive hearing loss (blood in the left external ear canal, no visible tympanic membrane, no correct identification of BAER peaks, latencies not measurable, 80 dB); horses with head shaking: mild sensorineural hearing loss on both sides (on both sides osseous parts II/III with keratin scales of the junction, visible tympanic membranes, significantly prolonged V, I-III, I-V, 40 dB); moderate to severe skittish horses with chronic eye disease (mostly left sided equine recurrent uveitis): moderate sensorineural hearing loss on both sides (normal otoscopical findings, significantly prolonged latencies and interpeak latencies left; I-V, III-V right, 60 dB, pathological involvement in the auditory pathway of the brainstem between the cochlear nucleus and colliculus caudalis); horse with a tinnitus on both sides: mild sensorineural hearing loss on both sides (normal otoscopical findings, prolonged V, I-III, I-V, III-V, 40 dB, pathology of auditory nerve, cochlear nucleus and above the level of this nucleus); American paint horses: sensorineurale deafness on both sides (normal otoscopical findings, absent BAER peaks, isoelectric lines and 80 dB on both sides).

An attempt is made to identify critical points that can favorably influence the prognosis of this orthopedic disease. All horses treated for a navicular fracture at the Equine Clinic, Vetsuisse Faculty, University of Zurich between 2005 and 2017 were included in this study. The severity of lameness at initial examination, radiographic assessment, hoof conformation, treatment (conservative or surgical), complications and outcome were determined from the medical records. Conservative and surgical treatment consisted of stable rest, a controlled exercise program and therapeutic orthopedic shoeing. During surgical treatment, fracture reduction was also carried out with a cortical screw. Computer assisted surgery were used in five horses and computer tomography in three horses. Follow-up examinations included clinical and radiographic examinations. The outcome was divided into three categories: 1 = very good; 2 = good; 3 = poor. Twelve horses met the inclusion criteria; Four horses were treated conservatively and eight were treated surgically. After conservative treatment, two horses (50 %) had a very good outcome and two (50 %) had a good outcome. After surgical treatment, four horses (50 %) had a very good outcome and four (50 %) had a poor outcome. Overall, 67 % of horses had a very good or good outcome, although radiographic signs of bone healing was not present in any of these cases. Various complications were identified, such as the fracture of a screw, the fragmentation of the small navicular bone fragment, the development of osteoarthrosis in the coffin joint and progressive podotrochosis.

The aim of this study was to record the influence of raw feeding on the occurrence of mastitis, metritis and the survival of puppies. An online questionnaire was sent to kennel club registered dog breeders in Germany and Switzerland. A total of 531 litters were recorded and evaluated. Mastitis and/or metritis were present in 9,2 % and 2,8 % (n = 49 and n = 15, respectively) of the breeding bitches. 29 % (n = 154) of the breeders reported loss of puppies in the litter.

The occurrence of puppy losses in the litter and/or a higher proportion of puppy losses in the litter was favored by increased body weight of the bitch in larger dog breeds, existing previous illnesses, previously reported gestation or postpartum problems, increasing length of the parturition phase and/or a cesarean section. A higher total number of surviving puppies was associated with increased weight and anamnestic reported health of the bitch and the use of milk powder instead of other milk substitutes.

After an enrichment step, Shiga-toxin encoding genes (stx) were detected by real-time PCR in 41 % (95 % confidence interval (95 %CI) 0,29 - 0,53) of the samples, and STEC were subsequently recovered from 22 % (95 %CI 0,13 - 0,34) of the same samples. Seven different serotypes and six different sequence types (STs) were found, with O146:H28 ST738 (n = 4) and O100:H20 ST2514 (n = 4) predominating. Subtyping of stx identified isolates with stx1c/stx2b (n = 1), stx2a (n = 1), stx2b (n = 6), and stx2e (n = 6).
