William, O, Portas O, Samuel O, Maurice O, Rubina A.  2013.  Survey of bacterial and parasitic organisms causing disease and lowered production in indigenous chickens in Southern Nyanza, Kenya. Abstractabstract2.pdfWebsite

A cross-sectional study was carried out to identify bacteria and parasites that caused disease and lowered productivity in indigenous chickens in Rachuonyo and Migori districts in Southern Nyanza, Kenya. A total of 21 chickens from 11 randomly-selected homesteads, within a group that was recruited into the African Institute of Capacity building and Development (AICAD) project, were used in the study. The chicken-keepers routinely vaccinated their birds against Newcastle disease and were recovering from an outbreak of Gumboro disease which had caused high mortalities. Picking of the chickens for postmortem examination was by random selection at household level and also geared towards picking those that showed signs of disease. Bacterial isolations were done from pooled oro-pharyngeal and cloacal swabs, and swabs from liver and/or other organs showing pathology. Parasitological isolations were done from skins and gastro-intestinal tracts. Pasteurella and Klebsiella were isolated from cases that were showing respiratory signs, while Salmonella Gallinarum was isolated from liver and spleen of a few birds showing signs of mild peritonitis. Other bacteria isolated, from oro-pharyngeal and cloacal swabs, included: Staphylococcus, Bacillus, E. coli, and Enterobacter. Aspergillus fumigatus was isolated from a case of skin wounds and defeathering. Parasitological isolations included: ascarids, tape worms, flukes, pin worms, tetrameres, stick-tight fleas and scaly-leg mites. These organisms were associated with various pathological lesions. Since they indirectly cause stress that is associated with increased susceptibility to other diseases and reduction in productivity of the birds, it was found advisable that, in addition to vaccination against the viral diseases, the poultry-keepers exercised regular deworming and dusting of the birds with acaricides, as well as treating the birds whenever they appear sick.

The overall objective of the study is to determine parasite carriage of village chicken of Mbeere district, Eastern province of Kenya. The study was conducted for over two seasons, the dry (January to March) and wet (October to December) season. Subsequently efficacy testing of selected antiparasitic drugs will be conducted. Twenty four birds of three age groups (chicks, growers and adults) were randomly selected from homesteads. The study showed that all chicken (100%) harboured ecto and endoparasites and 79.1% were infected with haemoparasites. With respect to ectoparasites, all the birds (100%) were infested, with lice, while 75% were infected with mites, 66.7% with ticks and 54.1% with fleas. The most prevalent nematodes were the caecal worms (91.7%), Tetramere species (54.1%), Gonglylonema (29.1%) and Coccidial oocyst (20.8%). Cestodes were also present in 91.7% of the samples. Haemoparasites had a prevalence of 83.3%. This study has shown that endo and ectoparasites are a common health problem in the village chicken in Mbeere District, Kenya. The studies for wet season and for drug sensitivity testing are still on-going.

Njagi, LW, Mbuthia PG, Nyaga PN, Minga U, Olsen JE.  2005.  A Study on Effectiveness of Seven Disinfectants Against Possible Bacteria Contaminants of Coops and Premises Inhabited by Indigenous Chickens and Ducks. Abstractabstract3.pdfWebsite

Seven commonly used disinfectants abbreviated as A, B, C, D, E, F and G (A is, Glutaraldehyde and Coco – benzyl dimethyl ammonium chloride; B is, Didecyldimethyl ammonium bromide 50% w\\v; C is, Sodium hypochlorite; D is, pine disinfectant and antiseptic; E is, chloroxylenol; F is, phenol and that for disinfectant G is, cresol and soap solution) were evaluated for their effectiveness in disinfecting coops and premises of indigenous chickens and ducks. Bacterial isolates from 14 samples (each sample comprising of a pharyngeal and a cloacal swab from one bird pooled together) from village chickens and ducks were used in this study. The isolates were taken to represent microorganisms in the birds\' environment. Results showed that effectiveness amongst the disinfectants varied markedly. Two disinfectants were very effective (sensitivity of 80% and 60% respectively), three were moderate (30% sensitivity, each) and two were ineffective. Some of them were effective only at a concentration higher than that recommended by the manufacturer. For effective disinfection occasional sensitivity testing is therefore recommended.

Bebora, LC, Bii CC, Waitindi HK.  2005.  Pigeon-Frequented Areas, Garbage Piles and Dog Faeces as Possible Sources of Candida and Cryptococcus Infections for Humans and Animals. Abstract

A study was carried out to establish the presence of Cryptococcus neoformans and Candida species in two pigeon-frequented areas; garbage piles from two separate sites in Nairobi, and dog faeces from Small animal clinic, University of Nairobi, Kabete. The sampling included both solid materials and air. Potato Dextrose agar, CHROMagar and urea media were used for isolation and characterization of these yeasts. Various species of Candidaand Cryptococcus neoformans were isolated in numbers ranging from 104 to 105 colony forming units per gramme or per 2-minute exposure to air; from both pigeon-frequented areas and garbage sites. Cryptococcus was isolated more than Candida species in pigeon-frequented areas, while the reverse was the case for garbage sites, both for solid and aerial samples. The dog faeces yielded Candida organisms mainly. The presence of these yeasts in both solid samples and air highlights the possibility of these areas, which are frequently traversed by humans and animals (including chickens and other birds), as being possible sources of infection for humans and animals. Aerial contamination means the organisms can be disseminated far and wide easily.
