Milk losses associated with mastitis can be attributed to either effects of pathogens per se (i.e. direct losses) or to effects of the immune response triggered by the presence of mammary pathogens (i.e. indirect losses). Test-day milk somatic cell counts (SCC) and number of bacterial colony forming units (CFU) found in milk samples are putative measures of the level of immune response and of the bacterial load, respectively. Mediation models, in which one independent variable affects a second variable which, in turn, affects a third one, are conceivable models to estimate direct and indirect losses. Here, we evaluated the feasibility of a mediation model in which test-day SCC and milk were regressed toward bacterial CFU measured at three selected sampling dates, 1 week apart. We applied this method on cows free of clinical signs and with records on up to 3 test-days before and after the date of the first bacteriological samples. Most bacteriological cultures were negative (52.38%), others contained either staphylococci (23.08%), streptococci (9.16%), mixed bacteria (8.79%) or were contaminated (6.59%). Only losses mediated by an increase in SCC were significantly different from null. In cows with three consecutive bacteriological positive results, we estimated a decreased milk yield of 0.28 kg per day for each unit increase in log2-transformed CFU that elicited one unit increase in log2-transformed SCC. In cows with one or two bacteriological positive results, indirect milk loss was not significantly different from null although test-day milk decreased by 0.74 kg per day for each unit increase of log2-transformed SCC. These results highlight the importance of milk losses that are mediated by an increase in SCC during mammary infection and the feasibility of decomposing total milk loss into its direct and indirect components. © The Animal Consortium 2016 [less ▲]

Milk losses associated with mastitis can be attributed to either effects of pathogens per se (i.e., direct losses) or effects of the immune response triggered by intramammary infection (indirect losses). The distinction is important in terms of mastitis prevention and treatment. Regardless, the number of pathogens is often unknown (particularly in field studies), making it difficult to estimate direct losses, whereas indirect losses can be approximated by measuring the association between increased somatic cell count (SCC) and milk production. An alternative is to perform a mediation analysis in which changes in milk yield are allocated into their direct and indirect components. We applied this method on data for clinical mastitis, milk and SCC test-day recordings, results of bacteriological cultures (. Escherichia coli, Staphylococcus aureus, Streptococcus uberis, coagulase-negative staphylococci, Streptococcus dysgalactiae, and streptococci other than Strep. dysgalactiae and Strep. uberis), and cow characteristics. Following a diagnosis of clinical mastitis, the cow was treated and changes (increase or decrease) in milk production before and after a diagnosis were interpreted counterfactually. On a daily basis, indirect changes, mediated by SCC increase, were significantly different from zero for all bacterial species, with a milk yield decrease (ranging among species from 4 to 33. g and mediated by an increase of 1000. SCC/mL/day) before and a daily milk increase (ranging among species from 2 to 12. g and mediated by a decrease of 1000. SCC/mL/day) after detection. Direct changes, not mediated by SCC, were only different from zero for coagulase-negative staphylococci before diagnosis (72. g per day). We concluded that mixed structural equation models were useful to estimate direct and indirect effects of the presence of clinical mastitis on milk yield. © 2015 Elsevier B.V. [less ▲]

Les pratiques thérapeutiques associant des animaux sont-elles des techniques thérapeutiques comme les autres ? Quelles sont les particularités de cette « médiation animale » dès lors que l’agent médiateur, l’animal, est vivant et partiellement ignorant du dispositif dans lequel il est inscrit ? Nous faisons ici l’hypothèse que les pratiques de médiation animale peuvent s’inscrire dans l’horizon de ce que Leroi-Gourhan nommait le « milieu technique », le « mi-lieu », cet entre-deux qui assure la rencontre, la mise en relation d’un vivant et de son monde. Ce mi-lieu n’a rien d’un cordon, même symbolique, qui relierait le patient, l’intervenant et l’animal. Il se présente plutôt sous la forme d’un écotone, du nom des écosystèmes qui se développent à la lisière de deux écosystèmes différents et dont l’écosystème côtier est le meilleur exemple. Nous nous appuyons sur les concepts de technique, de technique du corps, d’espace potentiel et de rituel pour essayer de comprendre ce processus de médiation dont un vivant animal est partie prenante et comment il se fait que des rencontres animales recèlent un potentiel thérapeutique [less ▲]

Dans l’histoire des « zoothérapies », l’un des enjeux a été de distinguer ce qui relève du champ thérapeutique à proprement parler de ce qui relève plutôt d’activités récréatives ou de soutien. Nombreuses sont les associations qui ont vu se développer en leur sein des controverses, parfois houleuses et acerbes, à ce sujet. Nous proposons ici d’envisager l’introduction d’animaux dans un dispositif d’aide ou de soin comme une pratique de médiation au sens fort du terme, qui permet de créer ce que Winnicott appelait un espace intermédiaire, dans lequel des effets thérapeutiques peuvent survenir.

Dans cet article, nous montrons que l'opération de médiation, parfois appelée "addition des cancres", qui consiste à additionner deux fractions en ajoutant entre eux les numérateurs pour obtenir le numérateur du résultat et en faisant de même avec les dénominateurs, n'est nullement dénuée d'intérêt, mais est parfois utilisée de manière assez savante.
