Bovine ehrlichiosis is a tick-borne rickettsial disease caused by Anaplasma phagocytophilum. The disease can also be transmitted to humans. Outbreaks in cattle have been described in many European countries. In Belgium, infections caused by Anaplasma phagocytophilum have been reported in humans and dogs; however this paper details the first report of ehrlichiosis in cattle herds in Belgium. The first case described was in a dairy herd located in east Belgium. Clinical signs included hyperthermia, polypnea and swelling of the limbs. The other case was diagnosed in a second, mixed purpose, herd in west Belgium. Within the second herd all of the affected animals came from the same pasture. All animals in that pasture showed recurrent hyperthermia and some also showed signs of mastitis and late-term abortions. Blood smears and serology revealed the presence of Anaplasma phagocytophilum in the majority of animals with pyrexia. Furthermore, the presence of leptospirosis, Neospora caninum and Q fever antibodies was tested by serological analysis but all results were negative. Paired serology for Adenovirus, BHV-4, BHV-1, BVD, PI3 and RSV-B did not show any significant seroconversion. Milk samples from cows affected by mastitis revealed minor pathogens. Fecal testing for the presence of Dictyocaulus viviparus in the first herd was negative. Recurrent pyrexia in pastured cattle is a non-specific sign, and can be related to several different pathogens. Bovine ehrlichiosis is transmitted by the tick species Ixodes ricinus which is known to be present throughout Belgium. Belgian practitioners should include ehrlichiosis in their differential diagnosis when confronted with pastured cattle suffering from recurrent pyrexia. [less ▲]

Since the early 1990s in Wallonia, coagulase negative staphylococci (CNS) have been identified as mastitis agent, both clinical and subclinical. As there epidemiological cluster has not yet been clearly classified between environmental and contagious pathogen, several questions subsists toward this class of mastitis etiological agents. From the late 1990s were the CNS represented 12% of infected quarters to 23% of all positive identifications in 2008, the CNS have taken a large part of the clinical cases of mastitis. Comparatively, CNS in Flanders represents only 7% of clinical cases identifications and 24% of subclinical cases. They still represent low inflammation pathogens, as for the average somatic cell count (SCC) of a CNS infection is 450.000 cells/ml (DETILLEUX, J. 1999. Preventive Veterinary Medicine, 41, 75-88.) but they represent for sure a source of treatment events in farm as for they provoke clinical mastitis. So, however they are seen as minor pathogens of a lesser matter regarding milk production drop, they still can imply a treatment a loss of discarded milk. Whether or not they should be treated could be approached through the Mammipack® project results. 124 common clinical mastitis events where sampled for bacteriology at day 0 and day 21 (Fig. 1). Farmer were asked to qualify the severity of the mastitis whether it had abnormal milk (score 1); abnormal quarter (score 2) or hyperthermia/anorexia (score 3). Also, they recorded the treatment used and we collected the SCC of each cow recorded, 2 months before the clinical signs until 3 months after. We decided to define as “chronic cases” cows showing SCC > 250.000 cells/ml the month before the clinical event and as “cured” cows showing SCC < 250.000 cells/ml the month after the event or the next one if the mastitis took place less than 15 days before test day. We could show that CNS infections still account for the least severe cases (Fig. 2), except for S. simulans, S. saprophyticus and S. hominis that shown some quarter indurations. While only 10% of clinical infection does remain clinically uncured to the farmer, figure 3 explains how 50% of CNS infections in our essay remained globally cured (Bacteriological and tissular), even if 40% of their treatments shown to be inadequate. Also, only one infection could be referred as a chronic case, all the others were acute cases. Though this study recorded a small amount of cases, yet we did not find any results differing from known characteristics of CNS infections. One interesting facts is the quite easy cure of the infected quarters given the poor quality of treatment. [less ▲]

CTX-M-15-producing Klebsiella pneumoniae and Escherichia coli emerged recently in Cameroon. CTX-M-15 was encoded by two different multiresistance plasmids, of which one carried an ISEcp1-bla(CTX-M-15) element flanked by a 5-bp target site duplication and inserted within a Tn2-derived sequence. A truncated form of this element in the second plasmid was identified. [less ▲]

This presentation gives an overview of my research devoted to the Late Egyptian possessive article pAy.f. It aims at examining the uses of an element whose meaning evolved through time. Rather than looking for the very first occurrences of pAy.f in the Old Kingdom texts, my main concern is to analyze closely its progressive spread as well as to outline the gradual steps of its semantic evolution across the pre-amarnian corpus (15th-17th Dyn., c. 1650-1350 b.C.). On the one hand, I highlight the process by which this recent construction gradually encroaches on the older one, and on the other hand, I define the the meanings of pAy.f in relation to its distribution according to text genres.

The ZNF91 gene family, a subset of the Kruppel-associated box (KRAB)-containing group of zinc finger genes, comprises more than 40 loci; most reside on human chromosome 19p12-p13.1. We have examined the emergence and evolutionary conservation of the ZNF91 family. ZNF91 family members were detected in all species of great apes, gibbons, Old World monkeys, and New World monkeys examined but were not found in prosimians or rodents. In each species containing the ZNF91 family, the genes were clustered at one major site, on the chromosome(s) syntenic to human chromosome 19. To identify a putative "founder" gene, > 20 murine KRAB-containing zinc finger protein (ZFP) cDNAs were randomly cloned, but none showed sequence similarity to the ZNF91 genes. These observations suggest that the ZNF91 gene cluster is a derived character specific to Anthropoidea, resulting from a duplication and amplification event some 55 million years ago in the common ancestor of simians. Although the ZNF91 gene cluster is present in all simian species, the sequences of the human ZNF91 gene that confer DNA-binding specificity were conserved only in great apes, suggesting that there is not a high selective pressure to maintain the DNA targets of these proteins during evolution.

An approach inspired of Model Predictive Control is proposed to determine a sequence of control actions aimed at alleviating thermal overloads in emergency conditions. The algorithm brings the line currents below their limits in the time interval left by protections, while accounting for constraints on control changes at each step. Its closed-loop nature allows to compensate for measurement noise and model uncertainties. [less ▲]

In case of failed angioplasty, coronary stenting has gradually emerged as a non-surgical method to restore vessel patency and optimize coronary blood flow. There is still little clinical and angiographic information on the use of radiopaque single loose interdigitating wire stents in angioplasty complicated by threatened or acute closure. Seventy-one patients received Wiktor stents after threatened vessel closure in 53 cases and acute closure in 18 cases. Stent delivery was successful in 98%. In-hospital death occurred in 1 case (1.4%). Stents occlusion were faced in 10 cases (14%), of which 6 presented early and 4 late after the procedure. Urgent bypass surgery was needed in 9 cases (12%) and 7 patients (10%) developed acute myocardial infarction. Serious bleeding complications occurred in 7 cases (10%) and vascular repair was performed in 4 patients (5%). During a follow-up of 20 +/- 10 months, 2 patients died, no myocardial infarction was observed and recurrence of angina was noted in 17 patients (24%). Angiographic analysis showed an acute gain in minimal lumen diameter of 1.71 +/- 0.22 mm and a late loss of 0.63 +/- 0.17 mm. Angiographic restenosis (diameter stenosis > 50%) presented in 20% of patients. Therefore, Wiktor stenting yields similar results than currently used stents in acute closure and strictly defined threatened vessel closure following angioplasty. [less ▲]
