ABSTRACT

In this review, we report a case of a bone's metastatic breast cancer in Malian patient treated by chemotherapy in whom SRAS-COV-2's diagnosis was made 9days after the onset gastrointestinal symptoms. Patient quickly died before any COVID-19's treatment. According to the poor outcomes of cancer patients with COVID-19, authors emphasize to an intensive attention to such patients in order to find the best therapeutic balance between the two pathologies during this pandemic.

ABSTRACT

Peste des Petits ruminants (PPR) is a devastating disease of small ruminants with high morbidity and mortality rates among susceptible animals. The disease is endemic in much of Africa, the Middle East and Asia and constitutes one of the major hurdles to the improvement of small-ruminant production in these countries. The causal agent of PPR, the Small Ruminant Morbillivirus (SRMV), previously known as PPR virus (PPRV) belongs to the genus Morbillivirus within the family Paramyxoviridae. SRMV can be categorized into four genetically distinct lineages (I to IV). Suspicion of PPR was first reported in Ethiopia in 1977 and since then genetic characterization of circulating viruses has identified lineages III and IV in the country. This study was undertaken to provide an update on the molecular epidemiology of PPR in Ethiopia by analysing animal tissue samples collected between 2011 and 2017. PPR positive samples were identified in four regions of the country. Sequence and phylogenetic analysis of fourteen RT-PCR positive amplicons revealed that all of the SRMV in the samples from 2010 to 2017 belong to sub-clade II of clade I of lineage IV. No lineage III viruses were identified.

ABSTRACT

Newcastle disease (ND) is endemic in West Africa, which has also experienced outbreaks of highly pathogenic avian influenza (AI) H5N1 since 2006. We aimed to estimate the prevalence and incidence of AI and ND in village poultry in Mali and to identify associated risk factors. A longitudinal serologic study was conducted between November 2009 and February 2011 using ELISA commercial kits to detect antibodies. Sera (5963) were collected from 4890 different poultry. AI was rare, with a seroprevalence of 2.9% (95% confidence interval [CI] 2.3-3.5) and a seroincidence rate of 0.7 birds per 100 bird-months at risk (95% CI 0.4-1.0). AI antibodies were short lived, with a seroreversion rate of 25.4 birds per 100 bird-months at risk (95% CI 19.0-31.7). Risk factors for AI were limited: temporal variation occurred, but proximity to a water body was a risk factor only when large populations of wild waterbirds were present. ND was very common, with seroprevalence of 68.9% (95% CI 61.9-76.0) and a seroincidence rate of 15.9 birds per 100 bird-months at risk (95% CI 11.9-19.8). ND seroreversion rate was 6.2 birds per 100 bird-months at risk (95% CI 3.6-8.9). Regarding risk factors for ND, temporal variations occurred, and ND was more likely to be present in the Sudanian agro-ecological zone than in the Sahelian zone, in chickens than in other species, in flocks with higher numbers of Guinea fowl, and in flocks that had access to a waterbody. Control efforts would benefit from further increasing the ND vaccination coverage of village poultry, although this was already quite high (54.9%) for an African country. Seroconversion seemed satisfactory in vaccinated poultry, since 90.0% (95% CI 87.6-92.4) of these had ND antibodies. Further research should investigate the apparent lack of an epidemiologic role of domestic ducks for AI in Mali (unlike in Southeast Asia) and the potential role of Guinea fowl as a reservoir for ND.

ABSTRACT

We aimed at characterizing commercial and traditional village poultry farming in Mali, with a focus on practices influencing the risk of transmission of avian influenza and Newcastle disease. Surveys were conducted in 2009-2011 in a study area covering approximately 98% of the Malian poultry population. Among the 282 commercial farms investigated, of which 64 had not been known by the government authorities, 83% were located within a 50km radius from the capitals of the country and regions and 54% had low biosecurity standard. Among the 152 randomly selected village household flocks investigated, characteristics were overall similar to those in other African countries but some differences were notable including a large flock size (median 44 poultry), a low presence of ducks and geese (11% and 1.1% of flocks, respectively), vaccination against Newcastle disease being common (49% of flocks), a low proportion of households selling sick and dead birds (0.7% and 0%, respectively) and limited cohabitation between poultry and humans at night. Our recommendations to limit the risk of disease transmission include (1) for commercial farms, to introduce compulsory farm registration and accreditation, to increase technical proficiency and access to credit for farms with low biosecurity, and to support poultry producer associations; (2) for village poultry, to promote better quarantine and management of sick and dead birds. Such detailed knowledge of country-specific characteristics of poultry production systems is essential to be able to develop more efficient disease risk management policies.
