Conceptualizing and Researching the Professionalization of Religious Education Teachers: Historical and International Perspectives
Current discussions on Religious Education (RE), both in Germany and England, focus on the quality of teaching and the professionality of teachers, but neglect the historical and institutional process of professionalization upon which conceptions of teaching quality and teacher professionality hinge. This article seeks to provide definitional clarity by differentiating between individual and collective professionalization; exploring teacher professionalization in general and in the special case of RE; and operationalizing the concept of RE teacher professionalization for the purposes of planned historical and international comparative research. A three-fold conceptualization of professionalization is proposed, consisting of the following inter-related levels: (1) initial and continuing professional development; (2) professional self-organization and professional politics; and (3) professional knowledge. The breadth, complexity and significance of the historical and institutional processes associated with the professionalization of RE teachers at each of these levels is described and discussed. It is argued that further historical and international comparative research on these lines would contribute a broader and deeper understanding of the presuppositions of RE teacher professionality beyond current debates

Comparison of Finnish meat inspection records and average daily gain for cattle herds differing in Mycoplasma bovis test-status
Detecting Mycoplasma bovis on cattle farms represents a challenge in the absence of an outbreak or cases of M. bovis mastitis, yet identification of an infection is essential to control the spread of the disease successfully. The objectives of this study were: (1) to determine whether meat inspection records can aid identification of cattle farms supporting M. bovis infection, and (2) to compare the average daily weight gain estimated from carcass weight for cattle originating from farms differing in M. bovis test-status. Meat inspection records were collected from two abattoirs in 2015; 80 677 animals in total. All the dairy and mixed breed cows and bulls used for meat production were categorized according to known M. bovis infection status of the farms from which the cattle were derived; positive, contact or control farms. The associations between animals from different M. bovis categories and lung lesions of bulls and cows (pneumonia and pleuritis), identified during meat inspection, and estimated average daily gain (ADG) of bulls, were investigated. The odds ratios for lung lesions, especially pleuritis, were higher in M. bovis test-positive or contact farms compared with control farms. Additionally, odds ratios for pleuritis were higher among animals from M. bovis test-positive farms and animals from contact slaughtering farms originating from M. bovis-free rearing farms. Bulls originating from M. bovis test-positive farms had higher estimated average daily gain than cattle from control farms. Meat inspection records can be used alongside other methods to detect M. bovis-positive farms where M. bovis causes lung lesions. (C) 2019 The Authors. Published by Elsevier Ltd.Peer reviewe
Characterisation of the course of Mycoplasma bovis infection in naturally infected dairy herds
Mycoplasma bovis causes bovine respiratory disease, mastitis, arthritis and otitis. The importance of M. bovis has escalated because of recent outbreaks and introductions into countries previously free of M. bovis. We characterized the course of M. bovis infection on 19 recently infected dairy farms over 24 months. Our objective was to identify diagnostic tools to assess the efficacy of control measures to assess low risk infection status on M. bovis infected farms. PCR assays and culture were used to detect M. bovis, and in-house and BioX ELISAs were used to follow antibody responses. Cows and young stock were sampled on four separate occasions, and clinical cases were sampled when they arose. On 17 farms, a few cases of clinical mastitis were detected, mostly within the first eight weeks after the index case. Antibodies detected by in-house ELISA persisted in the serum of cows at least for 1.5 years on all farms, regardless of the M. bovis infection status or signs of clinical disease or subclinical mastitis on the farm. Six out of 19 farms became low risk as the infection was resolved. Our results suggest that, for biosecurity purposes, regular monitoring should be conducted on herds by screening for M. bovis in samples from cows with clinical mastitis and calves with pneumonia, in conjunction with testing young stock by screening longitudinally collected nasal swabs for M. bovis and sequential serum samples for antibody against recombinant antigen.Peer reviewe
Short communication : Drying-off practices and use of dry cow therapy in Finnish dairy herds
The objective of this study was to survey drying-off practices and use of dry cow therapy (DCT) in Finland through an online questionnaire. The questionnaire was accessible to all dairy farmers of the Finnish dairy herd recording system in 2016 (approximately 5,400 farms). In total, 715 dairy producers across the country, representative of the Finnish dairy industry, participated in the survey. Cows were dried off gradually in most of the farms. Most farms (78%) reported using selective DCT, whereas 9% of farms did not use any DCT, and 13% of farms applied blanket DCT. A significant trend was observed with increasing herd size and proportion of farms using blanket DCT. Percentage of farms using blanket DCT was also higher in farms with automatic milking system. Farmer's own experience was the most commonly reported reason for choosing a particular approach to DCT. Microbiological testing of milk samples at dry-off was the preferred method of selecting cows for DCT; 82 and 64% of farms using selective and blanket DCT approach, respectively, reported testing milk samples before treatment. The second most common criteria for using antibiotic DCT were clinical mastitis history and high somatic cell count. A high number of farms using selective DCT reported treating only up to one-fourth of their cows at dry-off. Information acquired on drying-off practices in Finland allows for future monitoring of prudent antimicrobial usage at dry-off.Peer reviewe
Local host response following an intramammary challenge with Staphylococcus fleurettii and different strains of Staphylococcus chromogenes in dairy heifers
Coagulase-negative staphylococci (CNS) are a common cause of subclinical mastitis in dairy cattle. The CNS inhabit various ecological habitats, ranging between the environment and the host. In order to obtain a better insight into the host response, an experimental infection was carried out in eight healthy heifers in mid-lactation with three different CNS strains: a Staphylococcus fleurettii strain originating from sawdust bedding, an intramammary Staphylococcus chromogenes strain originating from a persistent intramammary infection (S. chromogenes IM) and a S. chromogenes strain isolated from a heifer's teat apex (S. chromogenes TA). Each heifer was inoculated in the mammary gland with 1.0 x 10(6) colony forming units of each bacterial strain (one strain per udder quarter), whereas the remaining quarter was infused with phosphate-buffered saline. Overall, the CNS evoked a mild local host response. The somatic cell count increased in all S. fleurettii-inoculated quarters, although the strain was eliminated within 12 h. The two S. chromogenes strains were shed in larger numbers for a longer period. Bacterial and somatic cell counts, as well as neutrophil responses, were higher after inoculation with S. chromogenes IM than with S. chromogenes TA. In conclusion, these results suggest that S. chromogenes might be better adapted to the mammary gland than S. fleurettii. Furthermore, not all S. chromogenes strains induce the same local host response
Bacterial species associated with interdigital phlegmon outbreaks in Finnish dairy herds
Background: Severe outbreaks of bovine interdigital phlegmon (IP) have occurred recently in several free stall dairy
herds in Finland. We studied the aetiology of IP in such herds, and the association of bacterial species with the
various stages of IP and herds of various morbidity of IP. Nineteen free stall dairy herds with IP outbreaks and three
control herds were visited and bacteriological samples collected from cows suffering from IP (n = 106), other hoof
diseases (n = 58), and control cows (n = 64). The herds were divided into high morbidity (morbidity ≥50%) and
moderate morbidity groups (9–33%) based on morbidity during the first two months of the outbreak.
Results: F. necrophorum subspecies necrophorum was clearly associated with IP in general, and T. pyogenes was
associated with the healing stage of IP. Six other major hoof pathogens were detected; Dichelobacter nodosus,
Porphyromonas levii, Prevotella melaninogenica, Treponema spp. and Trueperella pyogenes. Most of the samples of
acute IP (66.7%) harboured both F. necrophorum and D. nodosus. We found differences between moderate
morbidity and high morbidity herds. D. nodosus was more common in IP lesion in high than in moderate morbidity
herds.
Conclusions: Our result confirms that F. necrophorum subspecies necrophorum is the main pathogen in IP, but also
T. pyogenes is associated with the healing stage of IP. Our results suggest that D. nodosus may play a role in the
severity of the outbreak of IP, but further research is needed to establish other bacteriological factors behind these
severe outbreaks
