Item Evaluation of amoxicillin content in commonly used multisource Injectable brands in veterinary practice(Egypt’s Presidential Specialized Council for Education and Scientific Research, 2019) Gberindyer, A .F.; Olaogun, S. C.; Omotosho, O. O.; Adedokun, R. A. M.; Shima, F. K.THE AIM Is To Evaluate Amount Of Amoxicillin In The Array Of Its Injectable Formulations From Multisource Marketed And Commonly Used In Veterinary Practice In Nigeria. The Amount Of Amoxicillin In Each Of The 10 Brands Sampled Was Analysed Using A High-Performance Liquid Chromatography. Thereafter, Percentages Of The Labelled Amount Of Amoxicillin Were Determined And Compared With 90-120% Specified In USP And IP. Samples G, H, And J Contained 93%, 98%, And 108%, Respectively Of The Labeled Amount Of Amoxicillin, While B, C, And A Contained Only 39%, 56%, And 58%, Respectively. Again, Samples I, F, D, And E Contained 124%, 135%, 147%, And 413%, Respectively Of The Labelled Amount. Thus, Only Brands G, H, And J Passed Assay Quality Test (AQT) Since The Amount Of Amoxicillin They Contained Was Within The Specified USP And IP Range, And Are Considered Pharmaceutically Equivalent, Consequently, Interchangeable For Intravenous Administrations. Whereas, Brands A, B, And C Failed AQT Because They Contained Less Than The Amount Of Amoxicillin Required, So Even When Used Prudently There Could Be Therapeutic Failure, Bacterial Resistance, And Public Health Implications. Similarly, Brands D, E, F, And I Could Cause Toxicity And High Tissue Residues Because They Contained Higher Than The Required And Labelled Amount Of Amoxicillin. About 30% And 40% Of The Analysed Amoxicillin Brands Contained Less And More Than The Required Amount Of Amoxicillin, Respectively. However, 30% Contained The Amount Within The Specified Range. Consequently, There Is High Rate Of Substandard Amoxicillin Injectable Brands For Veterinary Use In Nigeria Hence The Need For Regular Monitoring.Item Clinico- haematological and biochemical features of natural Babesiosis in Nigerian breeds of Cattle(Animal Health and Production in Africa, 2018) Olaogun, S. C.; Adedeji, P. A.This study evaluated the haematological and biochemical changes associated with bovine Babesiosis. A total of 50 samples confirmed positive for Babesia spp from305 sera collected from clinically suspected cases of Babesiosis within a period of 9 months from some cattle farms in Oyo state, southwest Nigeria. Breeds were established by their morphological features, Age was estimated using rostral dentition and sexes morphologically determined. Haematological and Biochemical analysis were established by adopting standard procedures and the use of specific kits respectively. Results showed 32 (64%) was White Fulani breed, 8 (16%) was Sokoto Gudali breed, 8 (16%) was Red Bororo breed and 2 (4%) was Kuri breed. Female with 43 (86%), while the male had 7 (14%) susceptibility. Older cattle (≥4yrs) with 27 (54%) susceptibility, (3-3½yrs) with 17 (34%) susceptibility, while (2-2½yrs) had the least susceptibility of 6 (12%). Hematological analysis revealed best parameters in White Fulani breed with Mean ± SD of PCV 28.6 ±8.76, HB 9.3±2.98, RBC 7.5±2.44, while the least values were seen in Sokoto gudali breed with then following parameters; PCV 24.6±6.89, HB 8.1±2.29, RBC7.8±1.59. Biochemical analysis revealed White Fulani with the best values as follows; Total protein 5.5±1.87, Albumin 1.3±0.20, Globulin 4.2±1.73, Glucose 58.1±18.0, AST 60.3±15.68, ALT 50.7±14.80. For age group, the best parameters were observed in (3-3½yrs) group with the following; PCV 29.2±7.76, HB 9.4±2.72, RBC 7.6±2.52, Total protein 5.5±2.11, Glucose 56.9±20.31, AST 61.1±17.15 compared to age group 2-2½yrs with the following values; PCV 26.6±9.81, HB 8.3±3.28, RBC 7.1±2.27, Total protein 4.5±1.64, Glucose 49.3±20.85, AST 54±11.01. No significance difference in their indices except in blood urea nitrogen value which was significant among the breeds sampled. This investigation reveals variation in the susceptibility to natural Babesiosis among Nigerian cattle breeds, ages and sexes with generalise anaemia, lymphocytopaenia, neutrophilia, hypoproteineimia, hypoalbuminaemia and extremely low blood urea nitrogen.Item Antimicrobial Susceptibility Profiling and detection of Cefotaxime- Resistant Escherichia coli from Commercial Laying Hens, Indigenous Ducks and Chickens in Ibadan, Nigeria(Faculty of Veterinary Medicine, University of Ibadan, Ibadan, Nigeria, 2024) Amosun, E. A.; Kolapo, A. M.; Ojja, C. V.Cefotaxime is a critically important antimicrobial agent for thè treatment of infections in humans and animals. The upsurge in thè incidence of cefotaxime-resistant Escherichia coti from animai sources is of global public health importance. Avian pathogenic Escherichia coti is a Gram negative zoonotic bacterial pathogen. Infections by Escherichia coti usually occur following consumption of foods and water contaminated with faeces. The development of antimicrobial resistance in Escherichia coti is a concem worldwide. This study evaluated thè prevalence, antimicrobial susceptibility and cefotaxime resistant Escherichia coti in commercial laying hens, indigenous ducks and chickens in Ibadan, Nigeria. Cefotaxime resistant Escherichia coti isolates from thè cloacae of these poultry sources were tested for antimicrobial agents. The overall isolation rate of cefotaxime resistant Escherichia coti was 6.5% (6/93), 3.2% (3/93) and 10.0% (20/200) from indigenous ducks, indigenous chickens and commercial laying hens respectively. Cefotaxime resistant Escherichia coti isolates were 89.7%, 86.2%, 65.5%, 55.2%, 37.9%, 27.6%, 20.7% and 20.7% resistant to sulphamethoxazole, tetracycline, ceftazidime, amoxicillin -clavulanic acid, chloramphenicol, ciprofloxacin, gentamicin and ceftriaxone respectively. Whereas, 75.9%, 68.9%, 62.1%, 51.7%, 41.4%, 27.6%,10.3% and 10.3% susceptible to ceftriaxone, ciprofloxacin, gentamicin, chloramphenicol, amoxicillin-clavulanic acid, ceftazidime, sulphamethoxazone and tetracycline respectively. Multidrug resistant (MDR) was observed in 89.7% (26/29) of thè isolates which exhibited 2 (in indigenous ducks), 3 (in indigenous chickens) and 13 (in commercial laying hens) different MDR pattems to 7 antimicrobial classes of drug. Higher isolation rate of cefotaxime resistant Escherichia coti and remarkable numbers of thè isolates from commercial laying hens showed multidrug resistant than that of indigenous ducks and chickens. Misused of drugs was predicted in commercial laying hens. This study showed that thè indigenous ducks and chickens harbour multidrug resistant Escherichia coti and may contribute to environmental contamination through faecal shedding.Item Clinico-haematological features of dermatophilosis in indigenous breeds of cattle in Ibadan, Nigeria(Faculty of Veterinary Medicine, University of Ibadan, Nigeria, 2018) Olaogun, S. C.; Jeremiah, O. T.This study evaluated the clinical-hematological profiles in bovine dermatophilosis. A total of 50 dermatophilosis infected cattle were studied clinically and 50 blood samples taken from two different locations of Akinyele cattle market and Bodija Abattoir Ibadan. Hematological parameters such as PCV, Hb, RBC,WBC,Platelets, MCV, MCH, MCHC, Lymphocyte and Neutrophils were evaluated using standard procedures .The level of severity was classified based on the extent of the surface lesions and the chronicity as observed on the animals vis a viz body condition scoring system, hematological parameters under different breeds, sexes, ages and severity of disease condition were subjected to a one way analysis of variance (ANOVA) with no level of significance established at p < 0.05. White Fulani was the breed with the highest cases of dematophilosis (66%), females (86%) were more infected than males. Cattle within age bracket of 2-2½ years (38%) showed clinical signs of dermatophilosis more than other age groups. Sokoto Gudali breed had the highest values for most hematological parameters, while Kuri breed had the least values for most of the hematological parameters. Females showed better values than males. Age range 3-3½ years had most of the highest values. Mild infestation showed the highest values. Therefore, this study has been able to revealed variation to dermatophilosis susceptibility, Kuri breed, adult cattle and bulls appeared to be more resistance. The hematology in generalized dermatophilosis have been elucidated by this present study and have been found to vary with age, sex, severity of infection and breed of cattle.Item Evaluation of bacteria and antibiotic resistance profiling of Wara (White soft cheese) in Oyo- State, South West, Nigeria(Nigerian Veterinary Medical Association, 2017) Amosun, E. A.; Agbato, A. O.; Daodu, O. B.; Ojo, O. E.Fresh milk from healthy cows contains few bacteria but contamination during handling and processing can rapidly increase bacterial population and subsequently depreciate it quality. This study evaluated thè presence of bacteria and their antibiotic resistance profiles in white soft cheese (Wara) in three major producing locai Government areas in Oyo-State, Nigeria. The cheese samples were collected in sterile universal bottles immediately after production. Samples were immediately transported to thè laboratory for bacteria isolation, identification and antibiotic susceptibility test of thè isolates. A total of one hundred and sixty-five (165) bacterial isolates of ten different bacterial genera were identified from 102 cheese samples. The isolation rates of different species/genera were Lactobacillus spp (39.8%), E. coli (32.5%), Klebsiella spp (9%), Citrobacter spp (2.4%), Acinetobacter spp (3.6%), Pseudomonas spp (6.6%), Bordetella spp (0.6%), Proteus spp (1.2%), Staphylococcus spp (3.6%) and Strepiococcus agalactiae (0.6%). Results demonstrated substantial differences in their resistance pattems to various antibiotics. The isolates were tested against ten different antibiotics. The Gram negative isolates showed twenty-five resistance pattems while Gram positive isolates revealed fifty-four distinct resistance groups. In all, Gram positive isolates showed resistance to ceftriaxone (61.1%), gentamicin (51.4%), chloramphenicol (51.1%), amoxicillin (48.6%), ciprofloxacin (44.4%), cotrimoxazole (43.1%), perfloxacin (40.3%), streptomycin (40.3%) Erythromycin (31.9) and ofloxacin (30.6%) while Gram positive showed resistance to chloramphenicol (22.6%), trimethoprim /sulfamethoxazole (20.4%), amoxillin/clavulanic acid. (10.8%), streptomycin (9.7%), gentamicin (8.6%), sparfloxacin (6.5%), amoxicilin (5.4%), Perfloxacin (5.4%), ofloxacin (4.3%) and ciprofloxacin (3.2%). Multi-drug resistance to three or more antibiotics was observed in 69 isolates, 56 Gram positive and 13 Gram negative bacteria. This study confirmed that white soft cheese “wara” can be a source of bacteria with multidrug resistant phenotypes.Item Occurrence of Skin Abscess and Sensitivity Pattern of Associated Bacterial Organisms in Pigs on Ifelodun Farm Settlement, Ogun State, Nigeria(Faculty of Veterinary Medicine, Alexandria University, Egypt, 2016) Omotosho, O. O.; Olaogun, S. C.; Odukaye, A. O.Pigs are relatively prone to abscess formation especially in the skin. This study was designed to assess the occurrence of skin abscess in pigs on the Ifelodun farm settlement in Ogun state, South-West Nigeria and evaluate the antibiotic sensitivity pattern of bacterial organisms isolated from pus samples from the abscesses. A total of 2,909 pigs from 104 randomly selected farms on the Ifelodun farm settlement were physically examined. The anatomic locations of gross swellings on the skin were noted. Diagnosis of skin abscess was arrived at after palpation and aspiration of content. Pus samples from 14 intact abscesses were collected aseptically for isolation and sensitivity using standard cultural and disc diffusion method respectively. Data were analysed using descriptive statistics. 26 (0.89%) of the 2,909 pigs examined across 22 (21.2%) farms out of 104 farms surveyed were affected. The anatomic distribution of the abscesses includes 43.3%, 6.67%, 16.67% and 33.33% on the neck, forelimbs, trunk, and hind limbs respectively. None was observed on the head. 10 bacterial species were isolated from the 14 tested isolates with Arcanobacterium pyogenes (57.1%), Staphylococcus aureus (42.8%) and Escherichia coli (35.7%) being most frequently isolated. Antibiotic sensitivity profile varied with more isolates being sensitive to Erythromycin, Tetracycline, Gentamicin, and Chloraphenicol for gram positive bacterial species and Ceftazidine, Cefuroxime, Gentamicin and Augmentin for gram negative species. Swine skin abscess affects various body regions in pigs on Ifelodun pig farm settlement. The neck and hind limbs were mostly affected likely due to poor injection practices. Based on availability of veterinary preparation readily available in the Nigerian market, Gentamicin, Tetracycline and Erythromycin remain viable options for post-surgical management of the abscesses while Chloramphenicol should be avoided due to its deleterious effect on humans. Antibiotic sensitivity is recommended in cases of recurring skin abscesses in a pig or herd.Item Isolation and antibiotics susceptibility patterns of Escherichia Coli O157:H7 from selected dairy herds in Nigeria(African Union, InterAfrican Bureau for Animal Resources (AU-IBAR), 2012) Amosun, E. A.; Olatoye, I. O.; Adetosoye, I. A.This study determined the safety of milk from dairy herds obtained by hand milking method from two major cattle producing States of Nigeria by investigating the presence of Escherichia coli 0157:H7 and their antibiotic susceptibility pattern. Forty seven milk samples from Kwara and 63 from Kaduna States were obtained from selected indigenous breeds of dairy cow. Bacteriological analysis by culturing on MacConkey agar (MAC) and subcultured on Sorbitol MacConkey agar (SMAC) were done. Escherichia coli 0157.H7 were confirmed serologically using latex agglutination kits (OxoidR UK). The isolates were tested for susceptibility to five commonly used antimicrobial agents and plasmid transfer was also carried out using E. coli K12 356 recipient. Out of the 61 non-Sorbitol fermenting (NSF) E. coli isolated from the samples 33(30.0%) were confirmed as E .coli 0157.H7 serotype. Antibiotic Susceptibility profile showed that all the isolates were resistant to one or multiple antibiotics, resulting in six different resistance patterns. Sulphadimidine resistance was the highest with all the isolates (100%) exhibited resistance to this drug while streptomycin had the highest sensitivity. Out of the seventeen E.coli 0157.H7 isolates tested for plasmid transfer, eleven (64.7%) transferred their resistance to the sensitive E. coli K12 356 enblock, while the remaining six showed segregation. The preponderance of E. coli O157 in this study indicated that greater proportion of milk being produced for human consumption in Nigeria were not wholesome and could posed threat of transmission of zoonotic pathogens. The high proportion of multidrug resistance exhibited by the isolates and the plasmid transfer is of public health significance as they could confer resistance on both pathogenic and non-pathogenic bacterial population in the consumers. More so, the milk which were obtained traditional unhygienic hand milking are either consumed raw or improperly pasteurized. Hygienic milking, pasteurization and judicious use of antibiotics after properly diagnosis and sensitivity test against newer antibiotics are recommended.
