HIV/AIDS in a Community of Western Cameroon
This chapter aims at raising awareness on the prevailing HIV/AIDS situation in a community of West Cameroon. Overall prevalence was 5.21%. Males were more infected than females and individuals ≥ 36 years old recorded highest prevalence. There was no significant difference in prevalence with profession, analysis based on marital status revealed that unmarried were more infected as compared to married, based on the motif of test, those who made the test because of sickness were infected than those who did for pregnancy purpose. The year interval [2014-2016] recorded highest prevalence as compared to other year-intervals; usage of condom in sexual practice for prevention in such individuals showed low prevalence as compared to individuals who did not consider such a prevention option. HIV/AIDS prevails in the Fondonera Community of west region and serious sensitization on its occurrence/level is of vital importance to prevent future infections.

Ecological Aspects of Tabanids (Diptera: Tabanidae) in a Gabonese Cattle Ranch
To embark on an anti-vectorial fight against mechanical vectors of animal trypanosomosis, investigations were undertaken in order to determine the abundance, species diversity and daily activity of tabanids in a cattle ranch in Gabon. The nzi and vavoua traps were used to catch tabanids in three divisions of this ranch. In this study, 616 tabanids were captured: 349 (56.66%) in Division 1, 226 (36.69%) in Division 2 and 41 (6.66%) in Division 3. In the first Division, T. taeniola was the most abundant species with an Apparent Density (ADT) of 2.2, followed by H. pluvialis (ADT = 1.05). In the second Division, H. pluvialis was most abundant with ADT of 1.6, followed by T. taeniola (ADT = 0.38). In the last Division, the most abundant species was H. pluvialis (ADT = 0.15). Comparing the relative abundance of catches with sites (Divisions), we realized that there was no statistically significant difference in catches with trapping sites. It was noticed that Division 3 recorded the highest diversity index values. We realized that the nzi trap recorded higher tabanid catches than the vavoua trap. The diurnal activity rhythm of the most frequent species encountered slightly differed with prospection sites.
