Abstract
Abstract
To assess how SARS-CoV-2 has changed the demand for in-person health care, we retrospectively analyzed data on access to the emergency department (ED) of San Martino Hospital, the referral acute-care center in the Liguria region (Northwest Italy). 181,699 records of patients diagnosed with an ICD-9 code between 2019 and 2021 were considered. In comparison to pre-pandemic levels, following the introduction of social distancing measures, the median number of ED visits declined by 41.4% in 2020 and by 28.1% in 2021. The period of maximum drop in access (-58.6%) corresponded to the 2020 11-12th calendar weeks and coincided with the highest rates of COVID-like illness - defined as either ILI or LRTI cases - identified through an operator-dependent syndromic surveillance system (+340%; 19.5% of total ED attendances). In terms of relative impact, in 2020 and 2021 non-urgent ED codes decreased (by 6.7% and 7.3%) and both urgent and emergency ED codes increased (by 4.8% and 3.8% the former; 5.5% and 8.8% the latter), even so, the absolute number of ED access fell drastically for all codes. Urgent codes, in particular, experienced the most severe decrease, shifting from a pre-pandemic value of 25,009 to 18,826 in 2020 and 19,528 in 2021. With regards to diagnosis, in 2020, respiratory infections saw the highest increase (+3.3%) while traumas and eye diseases saw the highest decrease (-1.1% and -3.8%, respectively). This trend reversed in 2021 during which respiratory infections decreased (-2.2%) and traumas increased (+2.2%). Despite the admissions of males and the elderly being routinely lower, these categories experienced the greatest increase in access for respiratory infections: +3.9% and +10.1% in 2020; +2.8% and +7.4% in 2021. While reduction of non-urgent ED visits indicates that the high pre-pandemic access levels may have been avoidable, the significant decline in non-COVID-19 urgent accesses potentially points to an increase in delayed and missed care.
Key messages
• During the COVID-19 pandemic – possibly due to fear and underestimation of symptoms – there was an overall reduction in ED accesses that potentially points to an increase in delayed or missed care.
• The reduction in non-urgent attendances indicates that high pre-pandemic accesses may have been avoidable and that a reduction in unnecessary ED visits is an attainable goal for healthcare systems.

Abstract
Animal African Trypanosomosis (AAT or Nagana) is a severe vector-borne disease caused by protozoan parasites belonging to the Trypanosomatidae family and is usually cyclically transmitted by blood-sucking tsetse flies. AAT remains a major problem in sub-Saharan Africa. Among the main AAT causative agents, Trypanosoma congolense (T. congolense or Tc) is one of the most important trypanosome species, in terms of economic and animal health impacts, infecting cattle and a wide range of animal hosts as well. To advance in AAT prevention and control, it is essential to better understand trypanosome biology and pathogenesis using bloodstream form (BSF) in vitro culture. The in vitro cultivation of T. congolense IL3000 BSF strain is already well established and widely used in research studies and drug activity assays. However, it may probably no longer truly reflect the reality of field trypanosome strains, due to decades of use and subsequent modifications. Here, we propose a novel culture protocol that supports the long-term in vitro growth of the animal-infective BSFs of three Savannah and Forest types of T. congolense strains, including T. congolense clone IL1180, which is not only a field strain but also a commonly-used reference strain in experimental animal assays. We established a homemade culture medium which made it possible to sustain T. congolense IL1180 growth from infected mouse blood for 18 days in axenic conditions. Moreover, we developed an efficient freezing/thawing system that allowed, for the first time, T. congolense IL1180 BSF growth within 30 days after thawing. Our results on T. congolense adaptation to in vitro culture are encouraging for future gene studies using new molecular tools or for new therapeutic drug assays.

Abstract
Rinderpest (RP) and peste des petits ruminants (PPR) are contagious viral diseases of domestic and wild ruminants producing high mortality. They are caused by viruses belonging to the Morbillivirus genus, Paramyxoviridae family. Control tools (vaccines and specific diagnostic tests) exist for these two diseases. They have been successfully used during the global rinderpest eradication programme (GREP) and the disease is expected to be eradicated by 2010. In contrast, a similar programme does not exist for PPR, which is still spreading in Africa and Asia. The persistence of PPR in Turkey and its recent introduction in Morocco, make the disease a real threat for Europe. Improvement of control measures against PPR would benefit from the development of a marker vaccine and its companion serological test, thus allowing the differentiation between infected and vaccinated animals (DIVA vaccines and tests). The recent development of reverse genetics for morbilliviruses offers this new possibility.

Abstract
Peste des petits ruminants (PPR) is a highly contagious animal disease caused by a virus in the genus Morbillivirus, family Paramyxoviridae. This infection is responsible for high morbidity and mortality in sheep and goats and in some small wild ruminant species. The huge number of small ruminants, which are reared in the endemic areas makes PPR a serious disease threatening the livelihood of poor farmers. Taking advantage of the closely relationship between rinderpest and PPR viruses, the attenuated rinderpest vaccine was used in the control of PPR. It is now replaced by the homologous attenuated PPR vaccine. Unfortunately, animals that have received this vaccine cannot be distinguished serologically from infected animals. With the advent of DNA recombinant technology, efforts are being made to develop effective PPR marker vaccines to enable such differentiation and which would allow countries to implement both vaccination and disease surveillance programmes at the same time.

Abstract
The occurrence of outbreaks of peste des petits ruminants (PPR) in three districts of Tajikistan is described. The causal strain (PPR Tajikistan) was characterized and the sequence of its N gene was compared with that of 43 other strains isolated since 1968 in Africa, the Middle East and Asia. The study demonstrated (1) the value of the N gene as a target in comparing isolates obtained over an extended period of evolution, and (2) that clustering was related to the geographical origin of strains.

Abstract
A recombinant capripoxvirus vaccine containing a cDNA of the peste-des-petits-ruminants virus (PPRV) fusion protein gene was constructed. A quick and efficient method was used to select a highly purified recombinant virus clone. A trial showed that a dose of this recombinant as low as 0.1 PFU protected goats against challenge with a virulent PPRV strain.

Abstract
Sheep-pox and capripox are contagious diseases of domestic small ruminants for which the causal agent is a poxvirus classified into the Capripoxvirus genus. Viruses of this group have a host range specific to sheep, goats, cattle, and possibly buffalo. Thus, they are clearly indicated as vectors for the development of recombinant vaccines for peste des petits ruminants (PPR). Here we report the immune response of goats inoculated with a recombinant capripox-PPR hemagglutinin.

Abstract
The catalytic domains of two closely related cysteine proteinases (CP1 and CP2) from Trypanosoma congolense, referred to as C1 and C2, were expressed as proforms in Escherichia coli (C1) and in the baculovirus system (C1 and C2). While the bacterial expression system did not allow recovery of active C1, the baculovirus system led to secretion of inactive zymogens which could be processed at acidic pH into mature enzymes. Active C1 and C2 were purified from serum-free culture supernatants by anion-exchange chromatography and characterised. Their kinetic parameters and pH activity profiles confirmed the relatedness between C2 and native CP2 (congopain). These properties also underline major functional differences between C1 and C2, that appear to relate to discrete but essential sequence differences. It is likely that these two enzymes perform distinct roles in vivo, in the parasite and/or in the host-parasite relationships.
