“…12 main known pathogen to cause this disease. The disease is sporadic, with a prevalence rate of 0.2 to 5% in North America (28), which is similar to that observed in this study (0.8%). Horizontal and vertical cracks were accounted for 0.8% of lesions.…”

The objective of this study was to determine the prevalence of foot lesions in cattle slaughtered in the northwest of Iran. This study was performed on lower limbs of slaughtered cattle in four seasons of 2018-19. The feet of 400 cattle were divided into various zones to differentiate the lesions. The associations between gender and season with the lesions were assessed using the chi-square method and the results were presented as a percentage. P<0.05 was considered significant. The association between gender and season with the lesions was statistically significant (P<0.01). Lesions were observed in 61.5% of cattle and 78.5% of them were male. The lesions were more prevalent in autumn and winter (35.4%). 27% of total lesions were related to the forelimbs and 73% of them were related to the hindlimbs. Double sole and subclinical laminitis were the most frequent lesions of the limbs followed by sole, toe, and heel ulcers, white line disease, hoof cracks, interdigital hyperplasia, and interdigital necrobacillosis. Since a high percentage of slaughtered cattle in northwest Iran had at least one lesion in their feet, especially in the autumn and winter, it seems that proper management of herds is necessary to eliminate predisposing factors and improve livestock health.

“…In addition, Tranter and Morris (1991) identified an increase of pathogen susceptibility for DP under humid husbandry conditions. Kontturi et al (2017) reported less cases of DP in farms with mechanical ventilation, contributing to a reduction of the ammoniac concentration. Regarding the THI class effects (Figure 6D), THI classes 62 and 63 exhibited lower DP incidences than adjacent THI classes above and below.…”

The aim of the present study was to quantify the effect of heat stress (HS) from different points in time on production, female fertility, and health traits. In this regard, on-farm measurements for temperature and relative humidity were combined into temperature-humidity indexes (THI), and merged with longitudinal cow traits from electronic recording systems. The study included traits from 22,212 Holstein cows kept in 15 large-scale dairy co-operator herds. Trait and meteorological data recording spanned a period between May 2013 and November 2015. Longitudinal production traits considered 191,911 test-day records for protein yield, protein percentage, and milk urea nitrogen (MUN). Female fertility traits were the pregnancies per AI (P/AI) and the number of daily inseminations per herd cow (INS/ HCOW). Health traits considered clinical mastitis (MAST), retained placenta, puerperal disorders (PD) from d 0 to 10 postpartum, and the claw disorders digital phlegmona, digital dermatitis (DD), and interdigital hyperplasia from d 0 to 360 postpartum. For all traits, we analyzed the THI influence from the trait-recording day. In addition, we studied the time-lagged THI effect from the previous week. Linear mixed models were applied to estimate THI effects on Gaussian distributed production traits. For binary health and fertility traits, generalized linear mixed models with a logit link function were used. The continuous THI effect was either modeled linear, or via Legendre polynomials of order 4. Regression models for THI were validated via THI class effects (i.e., 5% percentiles for THI). Protein percentage decreased with increasing test-day THI, and with increasing THI from the previous week. Protein yield obviously decreased beyond THI 68 for both THI measurements (test-day THI and THI from previous week). For MUN, the visually identified test-day HS threshold was THI 70. Time-lagged THI effects on MUN were less obvious. For both THI measuring dates, INS/HCOW was highest at THI 57. Beyond THI 57, INS/HCOW substantially decreased. For P/AI, the visually identified HS threshold at the insemination date was THI 65. Temperature-humidity indexes from the previous week had a moderate detrimental effect on P/AI. Incidences for MAST, retained placenta, and PD during d 0 to 10 postpartum increased with increasing average THI from this period. Studying the whole lactation period, incidences for interdigital hyperplasia also increased with increasing THI from the previous week. An opposite THI response was identified for DD: DD decreased with increasing THI. For all health traits, associations between disease incidences and THI were almost linear. Hence, for health traits, no obvious HS thresholds were detected. Especially in early lactation, HS had a detrimental effect on cow productivity and female fertility. The influence of HS on cow health differed, depending on the disease pathogenesis.

“…Bovine interdigital phlegmon incidence in dairy cows is usually 2–5% per lactation, but some cases of outbreaks were also reported [35,58,92,93]. The role of T. pyogenes in the pathogenesis of this polymicrobial disease is not well defined.…”

Bacteria from the species Trueperella pyogenes are a part of the biota of skin and mucous membranes of the upper respiratory, gastrointestinal, or urogenital tracts of animals, but also, opportunistic pathogens. T. pyogenes causes a variety of purulent infections, such as metritis, mastitis, pneumonia, and abscesses, which, in livestock breeding, generate significant economic losses. Although this species has been known for a long time, many questions concerning the mechanisms of infection pathogenesis, as well as reservoirs and routes of transmission of bacteria, remain poorly understood. Pyolysin is a major known virulence factor of T. pyogenes that belongs to the family of cholesterol-dependent cytolysins. Its cytolytic activity is associated with transmembrane pore formation. Other putative virulence factors, including neuraminidases, extracellular matrix-binding proteins, fimbriae, and biofilm formation ability, contribute to the adhesion and colonization of the host tissues. However, data about the pathogen–host interactions that may be involved in the development of T. pyogenes infection are still limited. The aim of this review is to present the current knowledge about the pathogenic potential and virulence of T. pyogenes.
