Climate variability in DR Congo in general and in the Kongo Central Province in particular is well established. However, rains related to variables such as frequency of rainy days and duration of the rainy seasons was generally very little studied. This study aims to investigate the influence of the climate event on rainfall patterns in the south-western of the DRC. This is firstly to characterize the climate event from the analysis of the air temperature, the frequency of rainy days and duration of the rainy seasons. Furthermore compare the normal monthly rainfall over the period 1962- 2012 to clear the behavior of seasonal rainfall patterns. Climate variability is manifested by temporal dynamic regressive temperatures, annual rainfall and a decrease in the number of rainy days. A temperature increase of around 1 was observed from 1992 and the thermal peak was recorded in 1994 (>28℃). The highest rainfall was recorded in 2006 (>2400 mm). These variabilities cause short periods of intense rainfall leading to early droughts of the end of season.

Six new provitamin A hybrids (LY1001-14, LY1001-22 and LY1001-23,) and synthetic maize varieties (PVASYN13, PVASYN9 and PVASYN7) were tested for their agronomic performance and compared to a locally adapted improved open pollinated variety (SAMARU) in the central and western conditions of DRC. A randomized complete block experiment with four replications was used. Following data were collected: 50% male and female flowering, plant and ear aspect, diseases incidence, plant height, ear aspect, ear rot and yield. The results showed non-significant differences (p > 0.05) in disease incidence and ears rot. Significant differences were observed (p < 0.05) for number of days to 50% of male and female flowering, anthesis-silking interval, plant height, plant aspect, ear aspect, and yield. For yield, two hybrids (LY100-14 and LY1001-22) respectively out-yielded local check by 71% and 56% while one synthetic (PVASYN 9) out-yielded the local check by 31% and the two others were comparable to the local check. Thus the hybrids (LY100-14 and LY1001-22) and synthetic varieties (PVASYN 9 and PVASYN13) are ready to be recommended for release to contribute to better production and nutrition for vulnerable people.

In order to enhance the legumes potential advantages on the cereal yield in intercropping system by nitrogen direct transfer from legume to cereal, an intercropping experiment was conducted between eight maize varieties (07SADVE, 08SADVE 1, 09SADVE F2, Mudishi 1, Mudishi 3, VP0523, ZM538 and Samaru), cowpea (Vigna unguiculata var. H4) and soybean (Glycine max var. Vuangi) during November 2011-February 2012 season at INERA/Mvuazi in the south-western country of DR Congo. The experimental design was a Split plot with four replications, twenty six treatments were applied between maize varieties monocrops (40.000 plant·ha﹣1) and legumes in monoculture (360.000 plant·ha﹣1) and both of sole planting were combined. Evaluation of these soles planting was performed on basis of several intercropping indices (MYE, LER, ATER, RCC, A and CR), the monetary advantage index (MAI), Actual Yield Loss index (AYL) and intercropping index (IA). After data analysis, competitivity indices indicated the higher yields advantages of maize varieties in intercropping, especially Mudishi 3-soybean (MYE = 2836.300 kg·ha﹣1). The equivalent land ratio (LER) varied with 08SADVE 1variety between 0.70 and 1.66 in cowpea and soybean intercrops respectively, the Relative crowding coefficient (RCC) showed yield advantage of all intercrops except with 09SADVE F2, Mudishi 1 and 07SADVE. Aggressivity (A) showed dominance of maize in all intercrops, against the Competitive ratio (CR) showed that the competitivity was stronger on cowpea (from 16.42 to 98.63) than soybean (from 16.12 to 25.70). Actual yield loss (AYL) was negative in all intercrops with cowpea and soybean. Thus, the index of association (IA) informed that the negative values of the different intercrops were due to the maize price (1000 CDF·kg﹣1) and legumes price (1500 CDF·kg﹣1). Finally, the monetary advantage index (MAI = 922.92) and PCA had determined that intercrop with Mudishi 3-soybean as an economic efficiency intercrop than others mixtures.

Abstract: Maize production in tropical Africa is often negatively affected by drought. The main objectives of the present study were to 1) analyze the impact of water stress on the agro-morphological performance of two varieties of Quality Protein Maize (QPM) compared to two normal maize varieties and 2) assess their adaptive response in contrasting water environments. Agro-morphological responses to water deficiency of maize (Zea mays L.) were assessed in controlled experiments using four maize varieties, two normal maize (Zm725 and Mus1) and two quality protein maize (Mudishi1 and Mudishi3) varieties. They were subjected to three water regimes (100%, 60%, 30% water retention capacity) at the beginning of the bloom stage, using a Fischer block design with four replications. Significant differences (p < 0.05) among varieties, water regimes and their interactions for plant growth and production parameters were observed. Reduction of water supply to plants caused changes in aerial and underground plant growth. Plant stem height, foliar expansion, and root system development characterizing vegetative growth showed variation in varietal response to water regimes. Mus1 (normal maize variety) was the best adapted to variations in water regimes because they developed an important root volume to adapt to the effects of water deficit while maintaining their morphological and productive characteristics.

Abstract: Background The spectrum of bacteria associated with bacterial vaginosis (BV) has recently expanded through taxonomic changes and the use of molecular methods. These methods have yet to be used in large-scale epidemiological studies in Africa where BV is highly prevalent. Methods An analysis of samples obtained during a clinical trial of the management of vaginal discharge in four West African countries. Samples were available from 1555 participants; 843 (54%) had BV. Nucleic acids of 13 bacterial genera or species potentially associated with BV were detected through the polymerase chain reaction. Results The associations between various components of the vaginal flora were complex. Excluding Lactobacillus, the other 12 micro-organisms were all associated with each other at the p≤0.001 level. The prevalence of various bacterial genera or species varied according to age, sexual activity and HIV status. In multivariate analysis, the presence of Gardnerella vaginalis, Bifidobacterium, Megasphaera elsdenii, Dialister, Mycoplasma hominis, Leptotrichia, and Prevotella were independently associated with BV as was the absence of Lactobacillus and Peptoniphilus. However, Mobiluncus, Atopobium vaginae, Anaerococcus, and Eggerthella were not independently associated with BV. Unexpectedly, after treatment with a regimen that included either metronidazole or tinidazole, the proportion of patients with a complete resolution of symptoms by day 14 increased with the number of bacterial genera or species present at enrolment. Conclusions Numerous bacterial genera or species were strongly associated with each other in a pattern that suggested a symbiotic relationship. BV cases with a simpler flora were less likely to respond to treatment. Overall, the vaginal flora of West African women with BV was reminiscent of that of their counterparts in industrialized countries.

Abstract: objective: to determine the etiological role of pathogens other than neisseria gonorrhoeae and chlamydia trachomatis in urethral discharge in west african men. methods: urethral swabs were obtained from 659 male patients presenting with urethral discharge in 72 primary health care facilities in seven west african countries, and in 339 controls presenting for complaints unrelated to the genitourinary tract. polymerase chain reaction analysis was used to detect the presence of n. gonorrhoeae, c. trachomatis, trichomonas vaginalis, mycoplasma genitalium, and ureaplasma urealyticum. findings: n. gonorrhoeae, t. vaginalis, c. trachomatis, and m. genitalium - but not u. urealyticum - were found more frequently in men with urethral discharge than in asymptomatic controls, being present in 61.9%, 13.8%, 13.4% and 10.0%, respectively, of cases of urethral discharge. multiple infections were common. among patients with gonococcal infection, t. vaginalis was as frequent a coinfection as c. trachomatis. m. genitalium, t. vaginalis, and c. trachomatis caused a similar clinical syndrome to that associated with gonococcal infection, but with a less severe urethral discharge. conclusion: m. genitalium and t. vaginalis are important etiological agents of urethral discharge in west africa. the frequent occurrence of multiple infections with any combination of four pathogens strongly supports the syndromic approach. the optimal use of metronidazole in flowcharts for the syndromic management of urethral discharge needs to be explored in therapeutic trials.
