Abstract
The use of antibiotics in food animals and the nonobservance of the withdrawal period might result in the accumulation and persistence of residues in foods. The contamination of foods by antibiotic residues might induce health risks including allergy, gastrointestinal dysbiosis, antimicrobial resistance, and cancer to consumers. Therefore, this study was initiated to investigate the presence of antibiotic residues in raw eggs, raw milk, and beef collected at the wholesale and retail points in the three major cities of Cameroon and consumers' perceptions of the risk of antibiotic residues in foods. Qualitative antibiotic residue kits (PremiTest® and Delvotest®) were used to screen 407 samples of foods collected in markets of three towns (Ngaoundéré, Yaoundé, and Douala) in Cameroon. A structured questionnaire was used to evaluate the knowledge and attitudes of 1462 consumers toward microbial drug residues in foods of animal origin. Prevalence of residues of 70.55%, 17.39%, and 69.63% for beef, eggs, and milk, respectively, was observed. More than 1/3 of the respondents believed that the consumption of contaminated foods with antibiotic residues is a risk to their health and thought that allergies and intoxication they often experience are related to the consumption of contaminated foods. Most of them showed their willingness to pay more to acquire quality foods, free from antibiotic residues.

Abstract
BACKGROUND Tsetse flies are cyclical vectors of African trypanosomiasis (AT). The flies have established symbiotic associations with different bacteria that influence certain aspects of their physiology. Vector competence of tsetse flies for different trypanosome species is highly variable and is suggested to be affected by bacterial endosymbionts amongst other factors. Symbiotic interactions may provide an avenue for AT control. The current study provided prevalence of three tsetse symbionts in Glossina species from Cameroon, Chad and Nigeria. RESULTS Tsetse flies were collected and dissected from five different locations. DNA was extracted and polymerase chain reaction used to detect presence of Sodalis glossinidius, Spiroplasma species and Wolbachia endosymbionts, using species specific primers. A total of 848 tsetse samples were analysed: Glossina morsitans submorsitans (47.52%), Glossina palpalis palpalis (37.26%), Glossina fuscipes fuscipes (9.08%) and Glossina tachinoides (6.13%). Only 95 (11.20%) were infected with at least one of the three symbionts. Among infected flies, six (6.31%) had Wolbachia and Spiroplasma mixed infection. The overall symbiont prevalence was 0.88, 3.66 and 11.00% respectively, for Sodalis glossinidius, Spiroplasma species and Wolbachia endosymbionts. Prevalence varied between countries and tsetse fly species. Neither Spiroplasma species nor S. glossinidius were detected in samples from Cameroon and Nigeria respectively. CONCLUSION The present study revealed, for the first time, presence of Spiroplasma species infections in tsetse fly populations in Chad and Nigeria. These findings provide useful information on repertoire of bacterial flora of tsetse flies and incite more investigations to understand their implication in the vector competence of tsetse flies.

Abstract
To prevent and/or control infectious diseases in animal and human health, an appropriate surveillance system based on suitable up-to-date epidemiological data is required. The systematic review protocol was designed according to the PRISMA statement to look at the available data on infectious diseases of livestock in Cameroon from 2000-2020. Data were searched through online databases. Grey literature was comprised of dissertations and theses from veterinary higher education institutions in Cameroon. A random-effects model was used to calculate pooled prevalence using Comprehensive Meta-Analysis Software. Based on disease prevalence, major infectious diseases of livestock in Cameroon were gastrointestinal parasitosis (57.4% in cattle, 67.2% in poultry, 88% in pigs), hemoparasites (21.6% in small ruminants, 19.7% in cattle), bovine pasteurellosis (55.5%), fowl salmonellosis (48.2%), small ruminant plague (39.7%), foot-and-mouth disease (34.5% in cattle), and African swine fever (18.9%). Furthermore, other important endemic zoonoses in the country included: Rift Valley fever (10.9% in cattle, 3.7% in small ruminants), brucellosis (7% in cattle, 8% in pigs), bovine tuberculosis (4.7% in cattle), hepatitis E virus (8.4% in pigs) and bovine leptospirosis (2.5%). Most of the retrieved research were carried out in the Adamawa, Northwest, and West regions of Cameroon. The evaluation of existing data as evidence, albeit publication-specific, is an important step towards the process of prioritizing animal diseases, including zoonoses.

Abstract
Aim: The aim of this study was to investigate the effect of nutritional status of the Gudali cows slaughtered at the Ngaoundere abattoir on follicular population, quality, and oocytes yield. Materials and Methods: Blood and ovaries were collected from 81 cows aged 6.35±0.24 years (3-12 years old), with a body condition score (BCS) of 2.93±0.09 (1-5). In each ovary, the follicle were counted and classified as small (<3 mm), medium (3-8 mm) and large (>8 mm) using an electronic caliper. Oocytes were collected by slicing technique and classified according to the homogeneity of the cytoplasm and layers of granulosa into four groups: I, II, III, and IV. The nutritional status of the animals was determined by quantification of serum glucose, total cholesterol, total protein, albumin, globulins, urea, and phosphorus level. Results: Of the total 162 ovaries harvested, 2916 follicles were counted on the ovarian surface with an average population of 36.00±2.17 follicles/cow. According to a size distribution, 16.67±1.54 (46.3%), 18.83±1.27 (52.3%), and 0.51±0.07 (1.4%), respectively for small (<3 mm), medium (3-8 mm), and large (>8 mm) were recorded. About 1,929 oocytes were obtained, with an average recovered of 23.81±1.53 oocytes/cow. Depending on the quality, 7.79±0.55 (32.7%), 6.04±0.41 (25.3%), 4.89±0.44 (20.6%), and 5.10±0.54 (21.4%) oocytes qualities I, II, III, and IV were obtained respectively; with an average cultivable oocyte recovered of 13.83±0.89 (58%). Cows with BCS > 3 and a high albumin and phosphorus level showed a highest number of follicles and oocytes able for in vitro maturation. Conclusion: These results indicated that nutrition remains an important factor for the in vitro production of the good embryo and the BCS is a useful tool for the selection of females’ oocytes donors.
