“…These data are incomplete and does not address the prevalence of the disease, its distribution per region, and per age groups taking into account the herd structure. As for serological prevalence, an earlier report by Sidibé et al (2012), using the same serological test as in the present study, showed an overall individual prevalence of 14.1 % in the two regions of the Central Delta of the Niger River (Mopti and Segou). This first nationwide serological survey was therefore carried out for a better assessment of the prevalence of the disease and its distribution in Mali.…”

“…A parallel use of the c-ELISA test and the CFT is however advised for the serological diagnosis of CBPP as none of both tests can detect alone all positive animals during natural infection (Muuka et al 2011). This is confirmed in a study conducted by Sidibé et al (2012) by the observation of a negative conditional dependence involving a synergistic action of the parallel use of the two tests. This implies that to achieve maximum sensitivity, the two tests should be applied in parallel.…”

“…Nonetheless, the c-ELISA seems to be more sensitive than the CFT in detecting chronic and subacute cases during experiments and in endemic areas (Niang et al 2006;Sidibé et al 2012). It is important to note that like any serological test, c-ELISA tests have limitations since they do not differentiate postinfection antibodies from postvaccination antibodies.…”

A serological survey to determine the prevalence of contagious bovine pleuropneumonia (CBPP) in Mali was carried out by using the competitive enzyme linked-immunosorbent test (c-ELISA) on 8007 serum samples systematically collected from 199 cattle herds collected throughout the whole country. Results showed a national prevalence of 18.11 % at the individual level and 85.93 % at the herd level. Significant variations in the individual prevalence were observed between regions of the country and ranged from 4.63 % in Tombouctou to 54.88 % in Kidal. At the herd level, although there were variations between regions, a high prevalence was constantly observed ranging from 60 to 100 %, hence confirming the endemic nature of the disease across the country. The CBPP risk varied also between regions and was very low in Tombouctou (odds ratio (OR) = 0.4) but very high in Kidal (OR = 9.8). Similarly, the risk seemed higher in the animals of the over 3-year age group (OR = 1.6) compared to the other age groups. It was also observed that there was a slightly higher risk (OR = 1.3) in the females than in the males. This study confirms the presence of CBPP across the country and should help to elaborate strategies for the effective control of the disease.

Contagious bovine pleuropneumonia (CBPP) is a highly contagious disease of cattle caused by Mycoplasma mycoides subsp. mycoides Biotype Small Colony (MmmSC). The disease currently occurs in most of sub-Saharan Africa and where it is endemic and a major constraint for improving pastoral productivity. Following the persistence of this scourge, and in order to control this disease, a serological survey was conducted to determine the prevalence of CBPP in Niger. In fact, 1,590 sera were collected following a stratified sampling plan based on the risk factor of dissemination of CBPP. The analysis were performed at the Central Livestock Laboratory using the c-Elisa test. The results obtained show a wide distribution of the disease with an overall prevalence of 4.15% at individual level. The highest prevalences were recorded in the South-East regions [Zinder (7.5%), Diffa (7.5%)] and the West part [Tahoua (6.9%)]. The prevalence at the commune level was about 36.55%, which was relatively high. The prevalence at strata level was 36.55% (95% PI 0.2428–0.4882). The expected prevalences did not match those found. The results of this serological survey are considered the reference situation (T0) of CBPP in Niger with the PRAPS project, and allowed to the country to redefine control policies for better control of the disease at national and sub-regional level.

“…CBPP screening and diagnosis depends on either conventional isolation of the etiological agent or serological and molecular tests. The complement fixation test (CFT) and a competitive enzyme-linked immunosorbent assay (cELISA) are the two primary serological tests recommended by the world organization for animal health (OIE) [ 11 ] and are both characterized by wanting test sensitivity and specificity [ 12 ].…”

Mathematical Modelling of the Transmission Dynamics of Contagious Bovine Pleuropneumonia Reveals Minimal Target Profiles for Improved Vaccines and Diagnostic Assays

Contagious bovine pleuropneumonia (CBPP) is a cattle disease that has hampered the development of the livestock sector in sub-Saharan Africa. Currently, vaccination with a live vaccine strain is its recommended control measure although unofficial antimicrobial use is widely practiced. Here, modelling techniques are used to assess the potential impact of early elimination of infected cattle via accurate diagnosis on CBPP dynamics. A herd-level stochastic epidemiological model explicitly incorporating test sensitivity and specificity is developed. Interventions by annual vaccination, annual testing and elimination and a combination of both are implemented in a stepwise manner and their effectiveness compared by running 1000 simulations per intervention over ten years. The model predicts that among the simulated interventions, the ones likely to eliminate the disease from an isolated herd all involved annual vaccination of more than 75% of the animals with a vaccine that protects for at least 18 months combined with annual testing (and elimination of positive reactors) of 75% of the animals every six months after vaccination. The highest probability of disease elimination was 97.5% and this could occur within a median of 2.3 years. Generally, our model predicts that regular testing and elimination of positive reactors using improved tests will play a significant role in minimizing CBPP burden especially in the current situation where improved vaccines are yet to be developed.
