Abstract
Faecal shedding of catle as well as poultry and poultry
products have been implicated as a major source of
Salmonella infectons in humans. We sourced to isolate and
identfy Salmonella and Shigella species from catle dung in
diferent abatoir of Ile-Ife, Nigeria and to detect the route
of cross-contaminaton of Salmonella and Shigella from
animals to humans with antbiotc susceptbility of the
isolates recovered. All 40 samples taken were collected from
the dung of freshly killed cows which were placed within
sterile plastc containers and transported to the
Microbiology Laboratory. Each Sample was placed
aseptcally in sterile nutrient broth and incubated.
Microbiological analysis was conducted with samples
serially diluted and analyzed on Salmonella-Shigella agar by
the direct platng method. Biochemical tests were employed
to confrm the isolates including Gram staining, catalase,
oxidase, urease, glucose fermentaton and motlity tests.
The results showed that out of the ten (10) samples
collected in Odo-Eran area, Ile-Ife town, 4 (40%) samples
showed Escherichia coli growth, 4 (40%) Salmonella were
isolated and 2 (20%) Shigella-like organisms were isolated.
At God's Love Tabernacle (GLT) area in Ile Ife town, From the
20 samples taken, 7 (35%) showed Salmonella isolates, 7
(35%) confrmed Shigella-like characteristcs isolates. Six
(30%) isolates lef were observed to show Escherichia coli
colonies. The Salmonella/Shigella isolates obtained from
study areas were 100% resistant to chloramphenicol, 75% to
septrin and 10% to pefoxacin and tarivid respectvely while
the isolates were 80% susceptble to gentamicin and 65% to
ciprofoxacin and streptomycin used. Gentamicin
streptomycin and ciprofoxacin antbiotc therapeutc agents
will be efectve in the treatment of catle infectons caused
by Salmonella and Shigella species in the study area.
Epidemiological burden of Salmonellosis is expected to be
much greater in the developing parts of the world.

Introducton
Salmonella are the leading cause of bacteremia, 28.5% with S.
typhi accountng for 20.9% and non-typhi salmonella 7.6% [1].
Infectons due to salmonella serotypes contnue to be a major
health problem [2]. Worldwide incidence of shigellosis is
estmated to be 164.7 million cases per year of which 163.2
million were in developing countries, where 1.1 million deaths
occurred. About 60% of all episodes and 61% of all deaths
atributable to shigellosis involved catle and children below fve
years. The incidence in developing countries may be 20 tmes
greater than that in developed countries [3]. An estmated 30%
incidence of these infectons are caused by S. dysenteriae with
case fatality rates reaching 30% [3].
Salmonellosis is one of the most common and widely
distributed food-borne diseases. It consttutes a major public
health burden and represents a signifcant cost in many
countries [4]. Most Salmonella infectons in catle are
subclinical, and shedding of the organism can occur for extended
periods. Salmonella can also persist in the farm environment [5].
Shigella species are highly infectve, partcularly S. dysenteriae
considered the most virulent, and can produce a potent
cytotoxin known as “Shiga toxin”. Shigella dysenteriae type 1
causes severe and sometmes fatal disease. Shigella species have
been recently identfed to be the most frequently identfed
agent of laboratory-acquired infectons because of their high
virulence and low infectous dose [6].
In Nigeria, morbidity associated with illnesses due to
Salmonella contnues to be on the increase and in some cases
resultng in deaths [7]. It is common in developing countries
where afected populatons are immunologically compromised
due to poor nutriton and background infectons leading to high
morbidity atributed to shigellosis [8-10]. Salmonellosis, a major
cause of bacteria enteric illness in both humans and animals
cause diseases in humans and is referred to as a zoonotc
infecton/disease. It is a disease caused by the bacteria
Samonella [4].
