Introduction: Information on the prevalence of keratinophilic fungi in West Indies is scanty. Occurrence of keratinophilic fungi in soils of St. Kitts and Nevis has not been investigated previously. Methodology: The prevalence of keratinophilic fungi was investigated in 108 samples of soils of varying habitats from St. Kitts and 55 such samples from Nevis by hair-baiting technique. Fungal growths appearing on the hair baits after four to eight weeks of incubation at room temperature were microscopically examined and cultured on mycological media. Cultures were identified on the basis of colonial and microscopic features. Results: Forty-nine (45%) of the samples from St. Kitts and 38 (69%) from Nevis were positive for keratinophilic fungi. Microsporum gypseum complex, a well-known geophilic dermatophyte, was the most frequently recovered species being present in 15.7%  of soils of St. Kitts and 40% of soils of Nevis. The next commonest species recovered was Chrysosporium indicum, represented by 15 (13.9%) isolates from St. Kitts and seven (12.7%) isolates from Nevis. Other infrequently isolated keratinophilic species included Chrysosporium tropicum, Chrysosporium keratinophilum, and unidentified Chrysosporium species. Conclusions: This study is the first of its kind in the islands of St. Kitts and Nevis. A high incidence of M. gypseum complex in the soil of these islands is a noteworthy finding of public health significance.

Aims: Keratinophilic fungi include dermatophytes and a variety of other fungi. Information on their occurrence in several Caribbean countries is scarce. This study investigates occurrence of dermatophytes and other keratinophiic fungi in soils of Anguilla, British West Indies (BWI) and emphasizes its public health significance. Study design: Place and Duration of Study: The study was done in the Department of Microbiology, Saint James School of Medicine, Anguilla (BWI). One hundred and ten samples of soils from habitats in several localities in Anguilla were examined. Methodology: The samples were processed by Vanbreuseghem’s hair-bait technique. Bits of fungal growth on hair-bates were cultured on Mycobiotic agar to get pure cultures. Identification of the isolates was accomplished by a detailed study of colonial characters and microscopical features of the isolates. Results: Eighty-five isolates of keratinophilic fungi were recovered. The identified species included two geophilic dermatophytes, Micrsporum fulvum and M. gypseum and two species of Chrysosporium, namely Chrysosporium keratinophilum and C. indicum, M. fulvum was the predominant species being recovered from 35 (31.8%) of the soil samples followed by C. keratinophilum being isolated from 15.5% of the samples. M. gypseum was present in 8 (7.3%) of the samples. The prevalence of other species was as follows: C. indicum (13.6%), Chrysosporium spp. (4.5%) and Sepedonium spp. (4.5%). Conclusion: The preponderance occurrence of M. fulvum over M. gypseum and that of C. keratinophilum over C. indicum in soils of Anguilla is a remarkable observation. The farmers, other workers, school children who come in contact with soil are likely to be infected with a dermatophytes and also the visitors to the beaches and the local population nearby.

One hundred and fifty samples were collected from eleven districts of Vidarbha region of Maharashtra state and screened for the presence of keratinophilic fungi using hair baiting technique for isolation. Seventy-one isolates were recovered and identified. The cultures were identified using macro- and micromorphological features. Their identification was also confirmed by the BLAST search of sequences of the ITS1-5.8S-ITS2 rDNA region against the NCBI/Genbank data and compared with deposited sequences for identification purpose. Thirteen species of eight genera were isolated, namely, Auxarthron conjugatum (2.00%), Chrysosporium indicum (14.00%), Chrysosporium evolceanui (2.66%), Chrysosporium tropicum (4.66%), Chrysosporium zonatum (1.33%), Chrysosporium state of Ctenomyces serratus (3.33%), Gymnascella dankaliensis (1.33%), Gymnascella hyalinospora (0.66%), Gymnoascoideus petalosporus (0.66%), Microsporum gypseum complex (9.33%), Trichophyton mentagrophytes (2.00%), T. terrestre (3.33%), and Uncinocarpus queenslandicus (2.00%). This study indicates that the soils of Vidarbha region of Maharashtra may be significant reservoirs of certain keratinophilic fungi.

Although keratinophilic fungi on avian feathers have been widely described, data from European literature are quite lacking regarding Mediterranean countries. The aim of the present study was therefore to evaluate the occurrence of fungal species on feathers of different avian species in Italy. A total of 378 feather samples from both aquatic (n = 254) and terrestrial birds (n = 124), for a total of 30 bird species, were cultured for keratinophilic fungi. Fungal isolates were recognized by their macro- and micro-scopical morphology, and results were corroborated by PCR and sequencing. Keratinophilic fungi belonging to 11 different species (Scopulariopsis brevicaulis, Chrysosporium keratinophilum, Trichophyton terrestre, Microsporum gypseum, Sepedonium sp., Chrysosporium pannorum, Myriodontium sp., Chrysosporium tropicum, Chrysosporium pruinosum, Chrysosporium luteum and Aphanoascus fulvescens) were isolated from 71 animals (18.8%). The frequency of isolation of keratinophilic species from terrestrial birds was significantly higher in waterfowl. Migratory birds in Italy have been proven to carry pathogenic fungi such as dermatophytes, (A. platyrhyncos, A. crecca, E. rubecula), besides saprophytic species.

Keratinophilic fungi are the prime cause of various mycotic infections among children. Murtala Amusement Park is one of the preferred recreation grounds in Minna. The aim of this research was to investigate the occurrence of fungal species at Murtala Amusement Park, Minna, with the goal of identifying keratinophilic species among them. A total of 360 soil samples from six different important sites in the Park were collected during dry and rainy seasons. A total of 542 isolates from eleven genera were identified; Aspergillus, Candida, Fusarium, Paecilomyces, Mucor, Chrysosporium, Alternaria, Penicillium, Trichoderma, Microsporum, and Rhizopus.  A total of 142 and 399 fungal isolates were isolated during dry and rainy seasons respectively. Out of the soil physicochemical parameters analyzed, only Ca and Mg showed significant correlation with a number of the fungal colony at 1 % and 5 % levels of significance respectively and it occurred during dry season. There was no association between the numbers of fungal isolates recorded across the two seasons. Maximum percentage of contribution was observed with Aspergillus niger in both seasons. While the minimum percentage of contribution was observed with Microsporum gypseum (1.40 %) and Paecilomyces variottii (2.51 %) during the rainy and dry seasons respectively. Simpson’s dominance of fungal species showed 10.86 and 9.84 for dry and rainy season respectively. Evenness of fungal species at dry and rainy seasons were 0.0759 and 0.0247 respectively. Diversity index of fungal species were 2.531 and 0.908 for Shannon’s Index and Simpson’s Index respectively. A very high incidence of keratinophilic fungi demonstrated in the soil of Murtala Amusement Park is a noteworthy finding for public health significance.

This report represents the first study of keratinophilic fungi present in soils of Jamaica. Out of the 40 soil samples examined from different habitats, 30 (75%) were positive for the presence of keratinophilic fungi, yielding 36 isolates of keratinophilic fungi. Microsporum gypseum complex (represented by 16 isolates of M. gypseum, and four of M. fulvum) was most frequent, being present in 50% of the samples. A very high occurrence of this dermatophyte in Jamaican soil is of public health significance. The remaining isolates of keratinophilic fungi were represented by Chrysosporium spp (mainly C. indicum and C. tropicum) and Sepedonium sp.

Alkaline soils commonly called as <em>Usar</em> soil having pH 7.5 to 11.0 is commonly found in regions having poor drainage and little percolation. These soils occupy vast tracts of barren lands in the northern parts of India. These areas are frequently visited by man and animals, however there are no reports on the occurrence of keratinophilic fungi from the <em>Usar</em> soils. The purpose of this research was to study the occurrence of keratinophilic fungi in the alkaline Usar soil. To investigate the occurrence of soil keratinophilic fungi from <em>Usar</em> soil, 120 samples were collected from five districts of Uttar Pradesh viz. Lucknow, Bareilly, Azamgarh, Balia and Pratapgarh. Keratinophilic fungi were isolated by the hair baiting techniques using human hair as keratin bait. The cultures were identified using macro- and micro morphological features. Eighty-tow strains of keratinophilic fungi were recovered from 120 (68.33%) soil samples. The isolated fungi were composed of ten species of five genera viz. <em>Chrysosporium indicum</em> (19.16%), <em>Microsporum gypseum</em> (12.5%), <em>Chrysosporium tropicum</em> (10.0%), <em>Chrysosporium pannicola</em> (7.5%), <em>Trichophyton terrestre</em> (5.83%), <em>Chrysosporium lucknowense</em> (4.16%), <em>Chrysosporium</em> state of <em>Ctenomyces serratus</em> (3.33%), <em>Gymnascella dankailensis</em> (3.33%), <em>Gymnoascus reessii</em> (1.66 %) and <em>Trichophyton mentagrophytes</em> (1.66 %). The presence of keratinophilic fungi in the <em>Usar</em> soils of Uttar Pradesh, India indicates that these fungi do occur at higher alkalinity.

Mesenteric lymph nodes of slaughter cattle, swabs of slaughter and dressing areas and effluents of Zaria abattoir were cultured for salmonellae. Of a total of 510 samples cultured, 23 (5%) were positive for Salmonella. Five (4%) of 118 bovine lymph nodes contained salmonellae whereas sites swabbed during dressing had a frequency of isolation of 7% (11 of 150) and only 4 (3% of 150 samples) were positive after cleaning of dressing areas. Three (3%) of 92 effluent samples contained salmonellae. Thirteen of the 23 isolates of Salmonella were of different serotypes. The predominant serotypes were S. dublin (4 isolates), S. widemarsh (4 isolates) and S. Handoff (3 isolates). Twenty (87%), 8 (35%) and 8 (35%) isolates were resistant to streptomycin, neomycin and tetracycline respectively, while 6 (26%), 5 (22%) and 3(13%) isolates were not susceptible to gentamicin, ampicillin and chloramphenicol respectively. Overall, 15 resistance patterns were observed. The widespread occurrence of salmonellae in Zaria abattoir coupled with the high incidence of resistance to antimicrobial agents are of public health significance from the viewpoint of food hygiene and therapy for salmonellosis.

Four types of luncheon meats, bologna, chicken loaf, ham, and macaroni cheese, each manufactured by four different companies, were purchased from four major retail outlets in Ontario over a period of 16 weeks during the summer of 1975. Bacterial evaluation included determination of total aerobic plate count, coliforms, Escherichia coli, Staphylococcus aureus, Clostridium perfringens, salmonellae, and enterococci. Bacteria of public health significance were not a problem except for a high incidence of enterococci in all samples. S. aureus counts exceeded 1000/g in 20% of 30 positive samples out of a total of 159 samples. Total aerobic plate counts exceeded 5,000,000/g in 46.5% of the samples. Wide variation in bacteriological quality of the products between manufacturers was found.
