Background

Smallholder pig production plays a

big role in the livelihoods of several

communities in Uganda

Pigs potentially harbour several

pathogens, most of which might be

insidious.

There is poor management and

biosecurity in pig farms

There is lack of sufficient

information on pig diseases and

their economic impact in Uganda

Material and Methods

320 apparently healthy pig herds

were selected from 32 villages; 10

herds per village.

Household questionnaire completed

In each herd, up to 3 pigs were

sampled, in total 684 serum

samples.

Antibody ELISA was performed

using commercially available kits

Chi-square test was used to test for

any significant association between

the occurrences of pathogen’s

antibody with pig rearing, age and

breed type.

Conclusions and

recommendations

Research on pig pathogens in Uganda

normally focuses on the ‘big killers’,

such as African swine fever. This study

however highlights the need to conduct

more research on other pathogens,

since they could contribute to high

mortalities, but also because they

hamper productivity in pigs in Uganda.

Follow-up investigations to characterise

the most commonly pathogenic

serotypes and genotypes of the above

pathogens, and study the dynamics

and impact of these pathogens in

current smallholder pig production

systems are warranted.

Results

High prevalence observed for

Streptococcus suis, Leptospira.

spp, Porcine Circovirus 2 (PCV2),

Actinobacillus pleuro-pneumonia

(APP) and Mycoplasma

hyopneumonia (M. hyo.).

Significant differences were

observed between districts with S.

suis higher in Masaka (P=0.016)

and M. hyo, Influenza A, and

PCV2 higher in Lira (P=0.00,

P=0.00, P=0.03 respectively)

Pathogens Prevalence % (CI 95)

Aujeszky’s disease virus (ADV) 0.2 (0.00-3.62)

Porcine Reproductive and Respiratory

Syndrome Virus (PRRS)1.3 (1.64-11.28)

Porcine parvovirus (PPV) 4.5 (1.64-11.28)

Influenza A 5.8 (2.23-12.60)

Mycoplasma hyopneumonia (M. hyo) 15.4 (8.65-23.53)

Actinobacillus pleuro-pneumoniae (APP) 23.0 (15.00-33.00)

Porcine circovirus 2 (PCV2) 43.7 (34.08-54.28)

Leptospira spp. (Lepto) 70.6 (61.07-79.64)

Streptococcus suis (S. suis) 83.3 (74.18-89.77)
