ABSTRACT:
The study on the bioremediation of heavy metal by
bacteria isolated from mechanic workshop soil in FCT, Nigeria
was conducted. A total of fifteen (15) soil samples were
collected at random from motor mechanic shops in Lugbe (Abuja
Municipal Area Council), Kuntunku in Gwagwalada and Dutse-Alhaji
in Bwari, and in Gwagwalada, Bacillus cereus (3) was the
most occurring bacteria, followed by Bacillus licheniformis
(2) and only one (1) B. subtilis, and Pseudomonas
aeruginosa each, were isolated. In Dutse, Bacillus
subtilis (3) and Pseudomonas aeruginosa (2) were the
only bacteria present in the soil samples. Meanwhile, B.
subtilis (3) was the most prevalent in Lugbe soil,
followed by Pseudomonas aeruginosa (2), B. Megaterium
and Klebsiella pneumonia present has only one each.
B. subtilis was the most frequently isolated bacteria
with seven (37%), followed by five Pseudomonas aeruginosa
(26%), three B. cereus (16%), two Bacillus
licheniformis (11%) while and only one (1) B. Megaterium
and Klebsiella pneumonia represented (5%) each was
isolated. No effect was observed on heavy metal reduction by
Bacillus licheniformis and Klebsiella pneumoniae.
Pseudomonas aeruginosa had the most significant remediation
impact on cadmium and lead in the soils from the mechanic
workshop. Bacillus megaterium had a cadmium reduction of
1.24±0.00 µg/g and 1.36±0.00 µg/g of lead while Bacillus
subtilis and Klebsiella pneumoniae had no reduction
in the concentration of cadmium. However, further study should
be carried out to ascertain the bioactive substance in
Pseudomonas aeruginosa responsible for the bioremediation of
heavy metals such as lead and cadmium.

Abstract: A cross - sectional study was conducted from January
2024 to July 2024 in Dairy cattle in and around Asossa town
in order to estimate the prevalence of
mastitis, isolate and identify S.aurues from mastitic
lactating cows, assess its antimicrobial resistance pattern and
identify risk factors associated with mastitis.
A total of 369 Dairy cows milk samples were collected with
purposive sampling techniques. The overall prevalence of
mastitis at cow level was 39.56 % with 14.90 % and 24.66 % of
clinical and subclinical mastitis prevalence, respectively.
A
total of 1476 quarters were examined to detect clinical and
subclinical mastitis by physical examinations of udder, milk and
by California Mastitis Screening Test. From a total of 1476
quarters examined, 13.41 % (198/1476) and 23.37% (345/1476) of
quarters were affected by clinical and sub clinical mastitis,
respectively. In this study, the subclinical mastitis was
higher than clinical mastitis. For all except Age and
parity, intrinsic and extrinsic risk factors showed significant
value for the prevalence of mastitis in the study area (P˂0.05).
From 146 mastitis infected lactating cows, 543 milk samples were
cultured and 22.22% S.aureus were isolated.
The present result showed a significant association of
resistance pattern with S.aureus isolates, particularly
to amoxicillin (84.61%), penicillin G (78.84%), Cefoxitin
(76.92%), Tetracycline (69.23%), Streptomycin (61.53%),
Gentamycin (53.84%), and Vancomycin (61.53%). In this study,
76.92 % S.aureus isolates were resistant for Cefoxitin.
There were also observed multidrug resistance, mainly to
Penicillin G, Streptomycin and Tetracycline. The present study
revealed higher prevalence of mastitis and occurrence of
resistance S.aureus, which are dependent on multiple
associated risk factors. S.aureus to various
antimicrobials indicated that, there is existence of resistance
for frequently isolated mastitis bacteria to commonly used
antimicrobial agents in the study area. Hence, regular
resistance follow-up, using antimicrobials sensitivity tests
helps to select effective antibiotics and to reduce the problems
of drug resistance developments towards commonly used
antimicrobials.
