Mycobacterium bovis Isolates from Tuberculous Lesions in Chadian Zebu Carcasses
This slaughterhouse study in Chad shows higher proportions of Mycobacterium bovis isolates among Mbororo than Arabe zebu cattle, which suggests transborder and ongoing transmission between cattle.

Molecular Characterization and Drug Resistance Testing of Mycobacterium tuberculosis Isolates from Chad
ABSTRACT The molecular characterizations of the first 40 Mycobacterium tuberculosis isolates from Chad revealed a high proportion of isolates of the Cameroon family (33%), of which one isolate showed
Effects of elephant browsing on the vegetation in Kalamaloue National Park, Cameroon
Les effets du broutage par les elephants dans le Parc National de Kalamaloue ont ete evalues par echantillonnage sur des transects afin d'evaluer les degâts causes aux arbres par les elephants durant
Species identification of non-tuberculous mycobacteria from humans and cattle of Chad.
In Chad, during a study on tuberculosis in humans and cattle, 52 non-tuberculous mycobacteria (NTM) strains were isolated. By means of INNO-LiPA, PRA-hsp65 amplification and sequencing of 16S rDNA,
Studies on the maturation-accelerating pheromone of the desert locustSchistocerca gregaria (Orthoptera: Acrididae)
The accelerating effect of mature males of the desert locust on the maturation of immature male and female conspecifics was confirmed and the onset of sexual activity was found to correlate with yellowing of the male insects.
Mate Location Mechanism and Phase-Related Mate Preferences in Solitarius Desert Locust, Schistocerca gregaria
It is confirmed that both male and female solitarious locusts actively participate in mate location, although the former is the more aggressive partner.
Haemolymph Pigment Composition as a Chemometric Indicator of Phase in the Desert Locust, Schistocerca Gregaria
The blue biliverdin pigment in the haemolymph of Schistocerca gregaria Forskål was shown to be associated with all the stages and ages of the solitary-reared (solitarious) insects, irrespective of their origin or diet.
Effects of Fifth-Instar Volatiles on Sexual Maturation of Adult Desert Locust Schistocerca gregaria
A dual role for nymphal volatiles as nymphAl aggregants and adult maturation retardants, similar to the adult volatile that are known as adult aggregant and maturation accelerants are suggested.
The Role of Different Components of the Pheromone Emission of Mature Males of the Desert Locust, Schistocerca gregaria (Forskål) (Orthoptera: Acrididae) in Accelerating Maturation of Immature Adults
Different blends of five chromatographically prominent components of the pheromone emission of gregarious-phase mature desert locust males were bioassayed for their maturation-accelerating effects on immature counterparts.
